In this article, we dive into the specific features of both ducted and split system aircon installation.  We aim to equip you with knowledge required to make an informed decision by drawing on insights from industry experts.  This will help ensure your space is cooled efficiently, cost-effectively, and in harmony with your lifestyle and aesthetic preferences.

Join us as we explore the pros and cons of each main air conditioning type.  We hope that this will provide a clear pathway to a decision that will keep you cool and comfortable for years to come.

Section 1: Understanding Ducted Air Conditioning Systems

Reverse cycle ducted air conditioning systems offer a seamless way to cool or heat an entire property. These systems typically consist of an indoor unit concealed in the roof space and an outdoor unit located outside the property.  The 2 units are connected with copper pipework designed to transport refrigerant in a cycle of liquid and gas form.

The whole ducted system is controlled by a wall controller that also typically functions as a thermostat, unless zoning and room sensors are installed with zoned air conditioning.  Air is circulated throughout the home via a series of flexible ducts and rigid ductwork components.  Air is distribute into each room/area through air vents, and similarly returned to the air conditioning system by return air grille/s and filter/s.

Pros of Ducted Systems:

Full Coverage:  Ideal for large spaces.  Ducted systems help ensure even temperature control throughout the property​​.

Aesthetics:  Ducts and vents are usually hidden or unobtrusive.  This offers a sleek, stylish appearance​​.

Zoning Capabilities:  Many ducted systems allow for temperature control in different areas independently, with the use of room sensors.  This enhances comfort and energy efficiency​​.

Cons of Ducted Systems:

Higher Initial Cost:  There is generally a greater expensive upfront when it comes to the purchase and installation cost of ducted.

Installation Limitations:  Ducted systems require significant space for ductwork.  This makes them less suitable for certain structures or homes with limited roof space​​.

Control Limitations:  While zoning features offer some area-specific temperature control, they may not provide the same level of individual room climate control as split systems.  This can lead to energy wastage if cooling or heating unoccupied rooms​​.

When weighing up the pros and cons of ducted air conditioning, it’s important to investigate all options and compare the features to your specific property.  The assessment should not only include current demands and layout, but also any future plans such as renovations that may change your air conditioning requirements.

Section 2:  Exploring Split System Air Conditioning

Split air conditioners are just that; a split-design air conditioning system.  They are known for their two-component design with at least one indoor unit and one outdoor unit.  Most models on the market work using reverse cycle air conditioning principles.

You may be thinking; isn’t that the same as a ducted system?  You would be right!  A ducted system is technically a ‘ducted split system’.  However, in Australia, we tend to refer to wall split air conditioners as ‘split systems’ and split ducteds as ‘ducted systems’ for simplicity.

Split systems offer a distinct approach to climate control with a wide range of models available.  These typically consist of an indoor unit mounted on the wall, although they also come in floor-standing, under-ceiling, and even in ceiling in the case of cassettes.  They are connected by refrigerant pipework to an outdoor unit which houses key components, such as the compressor.

Pros of Split Systems:

Installation Flexibility:  Ideal for properties with limited space.  Split air conditioners can be installed in various locations without extensive ductwork​​.

Energy Efficiency:  Split systems often consume less energy than ducted systems when heating or cooling individual areas.  This reduces not only energy but also money wastage​​.

Cost-Effective:  Splits are generally less expensive to purchase and install upfront.  They also offer potentially lower running costs for specific area usage​​.

Cons of Split Systems:

Limited Area Coverage:  Split air conditioners are more suited for individual rooms rather than large, open spaces.  Large areas may require multiple AC units​​ or a multi-head system.

Aesthetic Concerns:  Indoor units may not blend well with interior décor.  External units can also impact the aesthetics of outdoor spaces​​.

Potential for Inconsistent Temperatures:  Since each split unit operates independently, varying temperatures can be present in different rooms or areas of a property​​.

When assessing the pros and cons of split system air conditioning, it’s important to consider all features and look at your property as a whole.  The review should not only include current aircon requirements, but any future events like kids or working location that may change your air conditioning requirements.

Section 3: Comparative Analysis

Several factors come into play when choosing between ducted and split air conditioning systems. The key factors include, but are not limited to, cost, efficiency, installation requirements, and specific needs of the property.

Cost and Installation:  Ducted systems are generally larger, more complex, and therefore more expensive to install.  This is particularly true in older style buildings and those with limited roof space.  In comparison, split systems offer more budget-friendly installation and flexibility in terms of unit placement​​​​.

Efficiency and Coverage:  Ducted systems have the advantage of providing more even temperature control throughout larger spaces.  Meanwhile, split air conditioners are more efficient for cooling or heating specific areas.  Split systems are subsequently ideal for smaller homes or single rooms​​​​.

Aesthetics and Control:  Ducted aircons offer a more integrated look, with vents seamlessly blending into the decor.  While split aircons provide more control over individual room climate conditions, they come with visible indoor units that may affect interior aesthetics​​​​.

Understanding these distinctions helps in making an informed decision that aligns with both your immediate and long-term requirements for climate control in your home or business.  However, there is certainly more to consider when it comes to making the right decision for you.

Section 4: Making the Right Choice for Your Home or Business

Choosing between a ducted system and split air conditioner depends on many factors, as we have discussed.  Further to the differences between the two AC styles, it’s also important to consider your property’s size, layout, and your personal preferences.

Assess Your Space:  Consider the size of your property and the number of rooms you need to cool or heat.  Ducted systems are ideal for larger properties requiring consistent temperature throughout.  Meanwhile, split systems are better for smaller spaces or individual rooms.  In some cases, a combination of split and ducted may be required.

Budget Considerations:  Evaluate your budget not only in terms of the initial purchase and installation, but consider long-term running costs.  A local HVAC professional can offer tailored advice as to the how to choose energy efficient air conditioning on a budget.

Energy Efficiency:  Think about energy consumption and efficiency.  Split air conditioning units can be more energy-efficient for heating or cooling specific areas.  However, you need to consider the energy costs associated with running multiple split units compared to one main ducted aircon system.

Aesthetic Preferences:  Consider how the air conditioning unit will integrate with your home or office design.  Ducted systems are less visible, whereas split systems require visible indoor units.  However, you can get increasingly stylish indoor units in a range of colours, with Industry-leader Daikin providing a colour palate selection in their home base of Japan, known as Risora Custom Style.

Consult with Professionals:  Finally, seek advice from HVAC professionals who can provide insights tailored to your home’s specific needs and constraints.  With dozens of different scenarios to consider, they can save you time and money while finding your perfect heating or cooling solution.

By carefully weighing these factors, you can make a decision that ensures comfort, efficiency, and satisfaction in your home or business.  There may be many different solutions that could work.  Ultimately, the aim is to make the right choice for now and into the future.


In the quest to find the perfect air conditioning solution, understanding the differences between ducted and split systems is crucial.  While ducted systems offer an integrated, whole-home approach ideal for larger spaces, split air conditioners provide flexibility and efficiency for smaller areas or specific rooms.

Your decision should be influenced by your property’s size, budget constraints, aesthetic preferences, and energy efficiency needs.  With this article, we hope you feel equipped to make an informed choice that aligns with your lifestyle and ensures lasting comfort in your home or business.

Air conditioners are an essential part of keeping a comfortable home, especially during the hot summer months.  With so many different types of air conditioners available today, it can be difficult to know what to look for when shopping for one.

One of the main considerations when buying an air conditioner is whether you are looking for a single unit, or if you want something with potential for more than one area to be cooled.  Split systems or multi-split air conditioning systems can cool multiple rooms at once, while ducted air conditioning can keep your entire home cool no matter how large it is.

The latest advances in technology have also led to the development of highly energy efficient units that can both save you money on energy bills and help protect the environment.  Inverter air conditioners offer cost effective temperature control and adjustable fan speeds which not only save money but also provide a quieter operation compared to other traditional models.

Additionally, there are a range of features to consider such as digital controls, adjustable louvers which direct airflow in all directions, and settings for different temperatures throughout the day.  With all these features to consider it’s important to take your time when selecting the right air conditioner for your home or business.

In this article we’ll explore some common mistakes you should avoid when looking to purchase an air conditioner.  We’ll also provide recommends on how to make the best air conditioning choices.  This will

ensuring that the air conditioner you buy is best suited to your space, budget, and needs.

1.      Not considering air conditioning.

If you are shopping for an air conditioner, don’t make the common mistake of not considering the many health, lifestyle, and economic benefits beyond the basic financial sense.  If you are looking to install air conditioning for the first time, you may be surprise as to the many benefits of air conditioning.

If looking to change over an existing air conditioner, replacing your AC system may seem expensive at first.  However, it could be the most financially viable option as repairs become more frequent and costly over time.  Also, at some point parts will no longer be available for your AC model.  You may not want to wait until it fails completely, only to have to wait weeks without air conditioning until a new system can be installed.

New air conditioning systems are also built to be more energy efficient compared to older models, which will help keep your power bills low in the long run.  If your home air conditioner is over 10-12 years old and requires frequent repairs, or is using too much energy, it may be worth investing in a new air conditioning system.

2.      Choosing the wrong air conditioner type.

Choosing the wrong air conditioner type for your home or business is a common mistake.  The right AC unit is essential for a comfortable and cost-effective heating and cooling solution.  When selecting the best type of air conditioning, it’s important to consider both current and future needs.

If you are looking to cool a single room, installing a wall split system or ceiling cassette system may suffice.  However, if more rooms need to be cooled in the future, this can quickly become very expensive as each unit must be installed separately.  It may then be more cost-effective to invest in a ducted system from the get-go.  This will reduce installation costs and save money in the long run.

Renovations may also alter your individual AC units’ performance, making them unsuitable for their new areas to be served.  Before investing in any aircon, think of all potential scenarios now and into the future so you don’t have to spend extra on fixing any issues later down the line.

3.      Automatically replacing with like-for-like AC.

Replacing an existing air conditioning system might seem like an easy option, but it is important to consider other options.  Replacing the existing unit with a like-for-like version without review is a common mistake.

Too many people fail to take the time to speak with a reputable AC installer who can offer insight on like-for-like or other options that may be appropriate for your property.   For example, a wall mounted split system may be more suitable than a floor mounted split or wall/window box unit.

When replacing an existing system, it is also important to ask 3 key questions:

  1. Did my original system adequately heat or cool the room?
  2. Has the function of the room changed since installation?
  3. Will the function of the room change in the future?

Answering these questions will help you determine if you need a different air conditioner type or different capacity (kW rating) when selecting a new system.

4.      Installing the wrong size air conditioner (kW).

Selecting the incorrect sized air conditioner a common mistake to be avoided.  This can lead to serious implications and significantly reduce the lifespan of your AC unit.  If your current unit appears undersized, it will continually run without rest and fail to bring indoor temperature up or down to desired levels.  On the flip side, an oversized air conditioner will cycle on and off constantly, resulting in premature damage and inconsistent air flow.

Before selecting aircon for a room or building, it’s important to remember the story of Goldilocks and the Three Bears.  Too small, too large – you need to get one that is just right!

Still in doubt?  Look up and consult a local HVAC contractor (e.g. searching air conditioning Brisbane), who can factor in multiple variables such as room size, ceiling height, building orientation, insulation, and window size/number to determine what kW rating you need.  A local installer will also have the insight into the best options for your city and climate.

5.      Selecting the wrong AC brand.

Selecting an air conditioner can be tricky, as there is no one AC brand that fits all.  Each brand has their own merits and drawbacks, and it’s important not to make the mistake of selecting just any brand without a second thought.

Rather than selecting an AC brand based on popularity or price alone, it’s important to consider all factors when deciding which air conditioner to buy.  Going for the cheapest option may cost you more in the long run if parts are expensive or unavailable.  Furthermore, some popular home air conditioners may have frequent issues such as long delays in spare parts or lack of parts before the system even reaches its reasonable lifespan.

The best thing to do is talk to a reputable air conditioning company about what brands they recommend and why.  Alternatively, you can research online for balanced and unbiased sources that can help inform your decision.

6.      Not considering type of aircon refrigerant.

Don’t make the mistake of thinking refrigerant type doesn’t matter.  Choosing the right gas in a new air conditioner is essential for several reasons.  First, certain refrigerants can be poisonous and cause long or even short-term exposure like R410A.  Second, the government is phasing out and heavily taxing certain refrigerants such as R22.

It is also important to make sure only the correct type of refrigerant is used in a new air conditioning system.  The wrong refrigerant can cause premature failure of internal components, resulting in costly repairs or even complete system failure.

Most importantly, incorrect refrigerant can reduce power efficiency.  Non-condensables can form in the pipework and build up inside the condensing coil.  This causes the AC to run at higher pressures, ramp up compressor electrical draw, and decrease heat transfer.  Ultimately, this leads to reduced efficiency or premature system failure.  This is why it’s important to consider refrigerant type at all stages.

7.      Not considering room design and AC style.

Many air conditioner selections occur without consideration for the style of the unit and how it will look in a room.  Air conditioners have become more attractive in recent years, making them better suited to modern and landscape designs.

AC units come in a variety of colours and finishes, including black, blue, red, metallic, and wood.  In some homes and businesses, bulkhead units are installed flush into the ceiling with only suction and discharge grilles visible indoors.  This helps reduce noise levels and preserves the aesthetics of a room design.

When comparing different air conditioning units, it’s worthwhile taking some time to compare AC models online and inspect them visually.  This will ensure you are not only happy with the function, but also the form that the AC unit will take in your home or workplace.

8.      Failing to review air conditioner models.

Another common mistake to avoid when in the market for air conditioning is selecting a new air conditioner based on price or presentation only.  It’s important to take the time to analyse different AC models available before committing to a purchase.

While it may be tempting to go with whatever model is on sale or readily available, it’s worth considering all relevant models including options from the same manufacturer.  This will allow you to determine which one is most suitable for you and your specific needs.

As a prime example, those looking for a Daikin air conditioner should thoroughly assess the differences between Daikin’s best wall split systems.  Doing so will ensure that you make the best decision based on price, needs, and budget.  This leads to the best value for money air conditioning system being selected.

9.      Buying air conditioning from the wrong supplier.

When it comes to purchasing an air conditioner, you want to be sure that you are getting the best possible deal and not going to the wrong source.  A good place to start is through an air conditioning company, as they usually offer package deals which can be cheaper than buying directly from a general retailer or even wholesaler.

The reason for this is because AC companies often buy their units in bulk and have trade accounts with wholesalers, allowing them access to greater discounts on air conditioners.  This should then be passed onto customers, helping them save money in the process.

If you do find a better price elsewhere, the cost of installation may not be included.  In this scenario, the cost of installation often ends up being significantly more expensive to offset the cheaper cost of the aircon.  This means that you may end up paying more overall when sourcing the new air conditioner separately from the installation portion.

10. Not considering how the AC unit will be installed.

It’s important not to forget the bigger picture when buying a new air conditioner.  Many people make the mistake of not considering post-purchase factors: transporting, carrying, storing, protecting, and eventually installing the AC units.  Not to mention all the materials and qualified labour that will also be required for the aircon installation.

All the steps that follow buying air conditioning units involve time, energy, planning, etc.  If purchasing AC units through a dedicated air conditioning company, much of this is eliminated for you.

It’s also worth remembering that you get what you pay for when it comes to air conditioning installation. Choosing a cheaper installer can result in greater expense, frustration, and pain in the long run. Professional installers use the correct materials and take the time to make sure it’s done right the first time.

If you look at things from an overall perspective, investing with a quality air conditioner installer may help you save instead.  A decent supply and install package can save you precious time, help prevent costly mistakes, and provide greater peace of mind knowing that your new air conditioning system is in safe hands from start to finish.

In summary, there are many factors to consider when finding the best new air conditioner for you or your business.  We have touched on the top ten things to look out for when buying air conditioning.  However, please be aware that there are dozens of other common air conditioning mistakes that can be made.

Throughout South-East Queensland, from the vibrant streets of Brisbane to the sunny stretches of the Gold Coast and Sunshine Coast, and out to the heat of Ipswich, the warmth of the sun is both a joy and a challenge.  There is nowhere we would rather be than in the Sunshine State.

A smoothly running air conditioner is a necessity with the challenging heat of Summer, often running unnoticed until it starts to struggle.  This can mean the difference between a cool comfortable oasis indoors vs a sticky tropical jungle invasion.

When your air conditioner starts to call out for attention, it may softly whisper or screaming out for repairs.  By paying attention to air conditioning, you can often avoid the inconvenience of a complete breakdown and the shock of emergency repair bills.  It’s important to listen out for the whispers and get your AC the help it needs.

The need for professional help is not just for the air conditioner’s benefit, although it can extend its life and limit the strain of existence.  It is also directly linked to your health and happiness over the warmer months and helps save money in the short and long term.

  • Repairing small air conditioning issues can often help prevent larger, more expensive issues.
  • Attending to a broken or inefficient unit can save money on running costs and power bills.

There are many signs that you need air conditioning repairs in both the residential and commercial HVAC settings.  In this article we will narrow down to 5 key signs that your air conditioning unit is whispering for help; from inconsistent cooling to rise in quarterly power bills, to unwanted noises, short-cycling, and moisture undermining your properties integrity.

Let’s unpack the five signs indicating it’s time to call the experts for an air conditioning repair near you.

Sign 1: Inaccurate Temperature Control

Has your lounge ever felt more like a sauna than a sitting room?  If the AC is on but controller setting seems to be nothing but a number, this is one of the most unmistakable signs that an air conditioning system needs repair.  Erratic temperature control is a symptom of distress, indicating that it’s not just about comfort but also a signal from the AC units that something’s wrong with its operations.

There are several reasons why this might happen:

Thermostat Troubles

If the brain of the AC starts malfunctioning, it can no longer command the system effectively.  The thermostat is typically part of the wall controller, although it can be a stand along component.  When faulty, the thermostat can result in an air conditioning system not generating enough cool air or even none at all.  Sometimes the issue may be as simple as needing new batteries.  Sometimes it needs recalibration.  Other times it can also indicate more complex electrical problems or sensor issues.

Compressor Complications

An AC compressor is integral to the cooling process and core component of how air conditioning works.  The compressor pressurises refrigerant to release heat.  If it’s not working properly, your aircon can’t maintain the set temperature.  This leads to a system that runs constantly without properly cooling the indoor environment.

Refrigerant Release

Refrigerant is the lifeblood of the air conditioning cooling process.  If it leaks or is contaminated, inadequate cooling can result.  This not only impacts performance but can also damage to the environment, internal and external.  Air conditioner components can fail if operating without designed refrigerant levels, while the ozone layer is damaged by released refrigerant gases.

Duct Dilemmas

Leaks or blockages in air conditioning ductwork can significantly impact temperature regulation.  Cool air can be escaping into your ceiling, walls, or outside environment instead of circulating through your home or office.  Ductwork components can also malfunction when insulation wears away.

Addressing these issues promptly can restore balance to your AC system, ensuring that your home or workplace returns to being the cool refuge expected in the Sunshine State.  Furthermore, it can prevent the problem from escalating, which helps protect against potential system failure and costly power bills.

If you’re constantly fiddling with the controller, yet comfort seems to be an elusive goal, it’s time to reach out for professional HVAC repair.  An expert technician can diagnose the problem, from thermostat to compressor, and provide the appropriate solutions to keep your air conditioner running smoothly.

Sign 2: Inflated Power Bills

Have you been experiencing bill shock as your quarterly energy expenditure soars higher than the summer temperatures outside?  An unexpected increase in your power bill could be the symptom of an air conditioning system in need of repair.  When an air conditioner is not running efficiently, it has to work overtime to cool an indoor area.  This leads to energy consumption that is anything but economical.

There are several things that may be contributing to this financial headache:

Aging AC

As air conditioners age, they often become less efficient.  This is especially true if they haven’t been serviced regularly.  Wear and tear on AC components can mean your system has to work harder to achieve the same level of cooling as before.  The question often becomes whether to repair or replace the AC.

Filthy Filters

Clogged or dirty air filters restrict airflow, forcing an air conditioner to use more energy to circulate air.  This not only affects your bills but can also put undue stress on the entire air conditioning system.  This excess strain can wear out the system faster, leading to premature failure.

Persistent Problems

If your air conditioner consistently has issues, this can increase running costs.  Worn out or broken parts such as fans and motors can cause inefficient operation.  These components may still be working but inefficiently, causing your unit to draw more power to compensate for their decreased performance.  Running an AC in this state also increases strain on other components, causing a continual chain of problems.

Ductwork Defects

If the ducts that distribute air throughout the indoor space are leaking, your air conditioner must run longer to cool the home or workplace.  This leads to increased energy usage.  Air leaks can significantly reduce the AC system’s cooling ability, while also adding dollars to your power bills.

To prevent these inefficiencies from burning a hole in your wallet, it’s important to take action easy and often.  Regular DIY AC maintenance can help keep your air conditioner running as efficiently as possible.

If you still notice a spike in your bills without a corresponding increase in usage or rates, it’s a clear sign to contact a HVAC professional.  They can perform a comprehensive system check to identify inefficiencies, repair faulty parts, and help restore your air conditioning to its cost-effective glory and get your energy expenditure back on track.

Sign 3: Irregular Noises

An air conditioner in good working order should run relatively quietly.  Some whispers are normal, such as a  low hum or the sound of air whooshing through vents.  Some people even like these AC noises to help them relax or sleep.  However persistent or unusual noises can signal that air conditioner repairs are required.  These sounds often serve as the audible clues that something is going wrong internally.

There are several different sounds that you might be hearing:

Banging or Clanking

These sounds can indicate that a loose or broken part, such as a blade, shaft, or other internal component, is knocking around inside your unit. This could cause significant damage if not addressed promptly.

Squealing or Screeching

High-pitched noises might suggest that the fan belt connecting to a motor has slipped or that bearings in the fan motor are starting to fail.  It’s not a sound to ignore, as it can precede a major breakdown event.

Buzzing or Humming

A buzzing sound can denote electrical issues, such as a failing motor, loose wiring, or other electrical components that are malfunctioning or not properly secured.  It can also be connected to a refrigerant issue in some instances.


Constant clicking sounds when the unit cycles on and off might point to a relay problem.  While a single click is normal when the system starts up or shuts down, persistent clicking is not.


This noise can be a telltale sign of a refrigerant leak or a ductwork issue.  Both are significant concerns that require immediate attention.

What to do when faced with these unsettling sounds?  First step is to shut down your AC system to prevent further damage.  Then it’s important to act quickly and call a professional technician to investigate the noise.  They can pinpoint the source and make the necessary repairs before minor noise issues turn into major mechanical failures.  Keeping an ear out for these audible anomalies can save you time, money, and the discomfort of living through a heatwave with an inoperative air conditioner.

Sign 4: Increased Cycling

Air conditioners are designed to go through relatively routine heating and cooling cycles, with the frequency increasing on the hottest days.  If you notice that your system is cycling on and off more frequently than usual, this could be a clear indicator that it’s time for some repairs.  Frequent cycling can put extra stress on your air conditioner and could lead to a decrease in its lifespan if not addressed promptly.

There are several possible causes behind this erratic behaviour:

Controller Concerns

If the AC wall controller includes the thermostat and is not accurately gauging the temperature, this can cause the air conditioner to turn on and off more frequently than needed.  An uncalibrated or malfunctioning controller might be the culprit behind the erratic cycling.

Oversized Operation

An air conditioner that is too large for the area served will cool down the space quickly, then shut off, only to turn back on a short while later when the temperature rises again.  This rapid on-and-off cycle can cause excessive wear and tear on internal components.  This situation often occurs when a room size has been changed (e.g. Home renos, office reconfiguration, etc.), or the heat load has changed (e.g. removed old heat-generating TV, added block out blinds, staff reduction, etc.).

Clogged Components

Restricted airflow due to a dirty air filter or blocked heat exchange coils can cause an AC unit to overheat and shut down.  Once it cools a bit, it will start up again, thus creating a cycle of frequent on and off that’s hard on the poor aircon.

Reduced Refrigerant

Refrigerant is essential for cooling in the air conditioning cycle.  If there is a refrigerant leak and reduced levels internally, the system might cycle on and off as it struggles to maintain the desired temperature.  This requires urgent air conditioner repairs due to the potential harm to you, your family, the aircon equipment, and the external environment.

To prevent these short cycling issues from affecting your comfort and your air conditioning efficiency, regular maintenance and timely repairs are key.  Replacing or cleaning the air filters, checking refrigerant levels, and ensuring the controller is working as designed are good first steps.

If the problem persists, it’s time to consult with an HVAC professional who can accurately diagnose the issue.  Ignoring frequent cycling can lead to bigger problems, so take this sign as a prompt to seek AC repairs ASAP.

Sign 5: Ice Build Up

When it’s scorching outside, finding ice anywhere can seem like a cool surprise.  However, if you find ice build up on your air conditioner coils, it’s no cause for celebration—it’s a red flag.  Ice on the evaporator coils of AC unit indicates a problem that could stem from multiple areas, impacting performance and potentially damaging the air conditioning equipment.

There are several common causes that explain the chill behind the frost:

Blocked Blower

When air filters are clogged or the indoor fan blower is restricted in any other way, it can prevent the evaporator coils from absorbing sufficient heat.  This causes condensation on these indoor heat exchange coils to freeze.

Low Levels

Refrigerant is what AC systems use to absorb heat from the air inside your home.  If there’s a low level of refrigerant in the system, it can cause the remaining refrigerant to become too cold as a result.  This leads to ice formation.

Malfunctioning Motors

Fan motors help in transferring warm air over the coils.  If they aren’t functioning correctly, then not enough heat is absorbed.  As a result, the coils can freeze over.

Caked Coils

When AC coils are caked with dirt, mould, grease, or any other matter, they are essentially insulated.  This prevents them from absorbing adequate heat, which can eventually cause ice to form.

HVAC repair service tech hosing and cleaning off coils

If your air conditioner turns into a popsicle maker, there are a few things you can do.  First and foremost, turn the system off to prevent further damage and allow the ice to melt.  Then check and make sure the filters are clean, cleaning or replacing them if needed to ensure proper airflow.

Once any ice has melted and only if safe to do so, then inspect the coils for dirt and fans to see if operating.  Then, or at any step before, call in a professional.  An HVAC technician can safely check over the system, pinpoint the issue/s, and handle any aircon repair indicators such as refrigerant shortage or blocked coils.

Ice on AC coils is more than a minor inconvenience—it can lead to a complete system shutdown if ignored.  By responding to the sign of icing up, you’ll help ensure the air conditioner keeps its cool without any frosty surprises.  The only place you really want ice is in your summer drink!

The Importance of Air Conditioning Repairs

Procrastination may be a natural part of human nature, but best to be avoided when it comes to the health of your air conditioning unit.  Attending to repairs in a timely manner helps ensure your air conditioner is operating correctly, efficiently, and ensures you get the most out of your investment.

Prompt air conditioner repairs can also significantly improve the air quality in your home or office by preventing issues such as mould growth or the circulation of allergens.  Some air conditioning brands have additional technology to help with allergies, but this is only one part of the solution.  The filters and internal components can harbour bacteria and disease, which can be blown out into the indoor area if an aircon is not serviced or repaired when needed.

A well-maintained air conditioner is synonymous with energy efficiency.  An aircon in need of repair can consume more electricity and skyrocket your power bills.  Issues like blocked airflow, refrigerant leaks, or faulty components force the unit to work harder, leading to inefficiency and energy wastage.  In comparison, quick AC repairs keeps your system running smoothly.  It also helps to preserve the indoor environment, outdoor environment, and contents of your wallet.

During the hot summer months in Queensland, the last thing you want is air conditioning breakdown.  A well-maintained AC isn’t just about physical comfort; it’s about peace of mind.  The reliability that comes from a properly serviced air conditioner means you can focus on enjoying summer days rather than worrying about when the next aircon outage will be.


As we’ve discussed, there are five critical signs indicating air conditioning repairs are needed.  Each signal a cry for help from your unit —a plea for air conditioner repairs ASAP.  If the cries are heard and attended to, this can save you time, money, and discomfort in the long run.

An efficient, functional AC system isn’t just a convenience, it’s a necessity in regions like Brisbane, Gold Coast, Sunshine Coast, and Ipswich.  Keep an eye and an ear out for these signs, and never underestimate the value of acting quickly.  Your air conditioner, and everyone who enjoys its cool relief, will thank you!

Contact a trusted HVAC professional to inspect and repair your air conditioning system.  They have the expertise and equipment to accurately diagnose issues and resolve.  The aim is to ensure that your air conditioning units are in optimal condition, ready to handle the heat of a hot and humid Queensland Summer.



Air conditioning systems have become a modern day essential in the home and workplace, especially in hot, humid regions such as Queensland, Australia.  Ensuring they operate effectively is not only vital for our comfort but also for our health and wallets.

Like all electronic equipment, air conditioners display signs and symptoms when they’re not at their best.  Being proactive and recognising these early warning signs can save you from a lot of discomfort and potential expense down the line.  Especially on hot, summer days where relative humidity in Brisbane and similar cities is consistently over 50% and temperatures 30 degrees +.

In this article, we’ll outline 7 clear signs that your air conditioning needs service.  These range from lack of airflow to lack of cooling, and from aircon leaking water to not enough moisture being removed.  We’ll also cover some of the reasons for an air conditioner service and provide actionable steps to ensure you know how to handle common aircon service indicators.

Sign 1: Air Conditioner Air Flow is Weak

Has your once-powerful air conditioner started to feel more like a gentle breeze?  Or even worse: you can’t feel any airflow at all?  Low or weak airflow can be one of the first signs that an air conditioning service is required.

There are a few main reasons why your air conditioner be underperforming in the airflow department:

  • Blocked Pathways: Similar to how we struggle to breathe with a blocked nose, your AC might be struggling to deliver that refreshing burst of cool air when its pathways are restricted.  This often stems from things like a dust-filled air filter or obstructions in the vents.
  • Motor Issues: The motor is the heart of your air conditioner airflow.  If it’s facing issues, it can directly impact the strength of the air being pushed out.

The unrestricted flow of air is essential not just for the efficiency of the AC units, but also for maintaining the desired temperature in your home or office.  Clean and clear pathways ensure that your air conditioner operates smoothly, uses less energy, and provides consistent cooling.  Think of it as giving your AC the lung capacity it needs to breathe and perform at its best!

Fortunately, there are a few checks and steps you can do for your air conditioner:

  • Aircon Filter: AC filters can affect airflow and are typically part of an air conditioner service.  It’s always a good idea to check and clean air filters regularly and replace when needed.
  • Airflow Obstructions: Important to keep an eye out for any obstructions that might affect airflow.  Check around both your indoor and outdoor condenser unit and remove any obstructions where safe to do so.

A little attention can go a long way in ensuring your space remains the cool haven you desire.  If you’ve done these checks and the problem persists, it might be time to consult with a professional for an air conditioning service to assess any potential AC motor or ductwork issues.

Sign 2: Air Conditioner Not Blowing Cold Air But Running

Common conundrum:  The air conditioner is humming along, appearing to be hard at work, and yet… the air isn’t cold?!  Puzzling and frustrating!  But don’t sweat it (literally and figuratively) – there are often straightforward reasons and solutions for this sign of air conditioner service being required.

There are dozens of reasons why an air conditioner is blowing warm air.  Two of the most common include:

  • Refrigerant Issues: Refrigerant is a key component of air conditioning.  It’s the substance that your AC uses to remove heat and humidity from the air.  If there’s a leak and it’s running low, the cooling capacity of your aircon can be severely affected.
  • Faulty Compressor: Another potential troublemaker could be a faulty AC compressor.  The compressor is essentially the powerhouse of your air conditioner.  If it’s not working properly, or any part controlling it is faulty, the whole cooling process can be impacted.

There are a few checks you can do at home or at work, provided safe access and precautions taken:

  • Controller Setting: It might sound basic, but sometimes the solution is as simple as ensuring the AC controller/thermostat is set to ‘cool’ and at the desired temperature.  Accidental bumps or fiddly fingers can sometimes change settings without us realising.
  • Circuit Breakers: Ensure that the circuit breakers for the AC unit are in the ‘ON’ position. Sometimes only the indoor unit can be running, and not the outdoor, leading to aircon not cooling.

If after these checks your AC is still more ‘warm’ than ‘cool,’ it may be time to look up air conditioning service near me.  An HVAC technician can take a closer look at potential refrigerant issues, compressor operations, and other technical aspects that might be causing your air conditioner to not blow cold air.

Sign 3: Noisy Air Conditioner

There is a certain level of noise from an air conditioner we don’t mind hearing.  In fact, we can certainly appreciate the gentle hum of an air conditioner working its magic on a hot day.  But when that hum turns into a squeal, grind, or buzz, that’s a different story.  That noise is a sign that an air conditioning repair service is needed, ASAP!

Different types of noises can mean different things:

  • Squealing: This can indicate a problem with a fan motor belt, suggesting it might be loose or slipping out of place.  Alternatively, it could be a sign of a motor bearing problem.
  • Grinding: This can indicate that bearings in the motor are wearing out.  Worst case, the grinding noise might indicate the motor assembly has completely failed.
  • Buzzing: This is a tricky one, as it can indicate a wide range of issues.  Buzzing can suggest loose parts, debris in the unit, refrigerant leaks, or electrical problems.

Ignoring these audible cues from your AC can be tempting, especially when the system still seems to be cooling your home or workplace.  However, ignoring your air conditioner telling you it needs a service can lead to more significant and typically more expensive damage down the road.  It’s similar to a small ache turning into chronic pain if left untreated.

There are a few initial things you can check when it comes to a noisy air conditioner:

  • Visual Inspection: Sometimes the cause of the noise can be as simple as twigs, leaves, or debris caught in the outdoor condensing unit.  Safely turning off the system and doing a visual inspection might help you identify and remove any obvious obstructions.  Only undertake this if 100% safe to do so.
  • Check the Insulation and Panels: Ensure all panels are secured correctly.  Loose panels can rattle, causing additional noise.  Also, over time the insulation that surrounds the AC unit might wear out, leading to increased noise levels.  Checking and replacing it might be a quick fix.  An HVAC technician is licenced to fix your AC insulation.

It the noises persists or if you require a professional solution, it’s best to contact an air conditioning service technician near you to look into it.  They’ll have the expertise to identify the root cause, carry out aircon repairs, ensure your AC runs smoothly and quietly, and move onto an air conditioner service where possible.

Sign 4: Smelly Air Conditioner


Have you turned your air conditioner on, only to get more than you wanted out of the AC unit?  While we love the cool breeze it provides, the unpleasant scent that can sometimes blow out instantly turns that relief into repulse.  If your aircon smells like vinegar, musty, weird in any way, it’s important to pinpoint the cause and treat accordingly.

There are a couple of common reasons for offensive aircon odours:

  • Bacteria: One of the worst smells from an air conditioner has to be a urine or vinegar-like odour.  This can be puzzling and concerning.  This smell is typically due to the build-up of bacteria within the unit.  Such a scent indicates it’s time for thorough aircon cleaning.
  • Mould and Mildew: Unsavoury mould spores and fungi can thrive in the damp, dark environment of your AC, especially in the ductwork, vents, or even the AC unit itself.  When an aircon is running, it can blow these particles into your indoor environment.
  • Burnt Wiring or Mechanical Issues: If you catch a whiff of something that smells like burning, it’s possible that the AC has an electrical issue, burnt wiring, or overheating parts.  This is a serious issue and airconditioning use should stop immediately.  An HVAC technician can help identify, repair, and then carry out a full air conditioner service to get your system back to full health.

Speaking of health, mould and bacteria build-up isn’t just a sensory annoyance… a smelly air conditioner can also be detrimental to your short- and long-term health.  Prolonged exposure to mould spores can lead to respiratory issues, allergic reactions, and other health problems.  These issues are especially severe for those with pre-existing conditions or sensitivities.  An aircon service is not just about keeping your home smelling fresh; it’s about ensuring a healthy environment for you and those around you.

To help reduce chances of a smelly aircon, there are things you can do:

  • Routine AC Maintenance: DIY air conditioning maintenance is a great starting point.  By regularly cleaning your AC filters, ensuring proper drainage, and other steps outlined, you reduce the chance of bacteria building up to smelly and dangerous levels.
  • Minimise Surrounding Moisture: It’s important to ensuring AC units and areas in the vicinity remain dry.  This can be done by controlling moisture sources, using the appropriate aircon settings, and ensuring adequate ventilation (naturally or mechanically).  These steps can significantly reduce the risk of mould and bacteria growth.

If you suspect that the odour might be due to electrical or mechanical issues, or if you’ve completed your own AC service and a musty smell persists, it’s time to call in a professional.  They’ll thoroughly inspect the system, identify the root cause, and guide you on the best steps to take to resolve and maintain your AC system.

Sign 5: Leaking Air Conditioner

It’s never a good sign when you spot a puddle near your air conditioner.  While air conditioners do produce condensation as part of their normal cooling process, that shouldn’t translate to aircon dripping water or water coming out of aircon in any undesirable location.

As part of the refrigerant cycle, air conditioners work by removing moisture from the air.  This produces condensation which is normally handled and drained away without the aircon leaking water.  However, when something goes wrong in this process, you might find yourself with unwanted water coming out of the indoor unit or system leaking water outside.

Apart from the obvious inconvenience, persistent water leaks are of concern for several key reasons:

  • Cause Structural Damage: Aircon dripping water can damage floors, walls, and even the foundation of your home over time.
  • Electrical Short Circuiting: Water and electronics do not mix, so any electrical fittings or personal items near the leaking air conditioner can be damaged.
  • Promote Mould Growth: Damp areas can become breeding grounds for mould and mildew, posing health risks and potential damage to your belongings.
  • Lead to Illness: Building up of mould and bacteria is linked to a range of short and long-term negative health outcomes.

If you do find yourself having to deal with a dripping air conditioner, here are two checks to consider:

  • Inspect the Condensation Drain: The most common cause of aircon leaks is a blocked condensation drain.  Check to ensure it’s clear of any obstructions, such as dirt, debris, or even algae growth.  Gently cleaning it out might solve your problem.  However, this is best left to the professionals in the majority of cases.
  • Check the AC Pan and Pump: The pan that collects the condensation can rust or get damaged over time, resulting in leaks.  Similarly, if you have a condensate pump installed, ensure it’s working properly.  Again, if you find this issue then it’s usually best to call in the experts.

If these steps don’t resolve the issue or if you’re unsure about the source of the leak, it’s best to call in a pro.  An air conditioning service technician will be able to diagnose the problem accurately and recommend the best course of action.  Remember, while a small puddle might seem benign, addressing it promptly can save you from bigger headaches in the future.

Sign 6: Humid Even With Air Conditioner Running

Stepping into a cool, dry home on a sweltering day is one of the joys of modern day living.  But what if your refuge feels more like a tropical rainforest than a refreshing oasis, even with the air conditioner running?  This is an often-unassuming sign that your air conditioner needs service.

Regulating the humidity levels indoors is one of the key roles of an air conditioner, apart from cooling the air.  By maintaining the right humidity level, an AC ensures a comfortable living environment and protects your home from issues like mould growth or excess dampness.  This is critical in regions like South-East Queensland, where humidity is typically over 50%.

There are a few common reasons why an air conditioner might not work as designed with humidity:

  • Size Matters: If your air conditioner is too big for the space it’s cooling, it might cool the room quickly but not run long enough to extract moisture effectively.  On the flip side, an undersized AC system might not have the capacity to handle the humidity levels.
  • Technical Issues: Issues with components like the heat exchanger evaporator coil or compressor can impact the ability of airconditioning to regulate humidity.
  • Age of the Unit: Older units might not be as efficient in moisture removal as newer equivalent models.  In addition, AC compressors lose efficiency over time.

A home or workplace that’s too humid can feel warmer than it actually is, generally leading to discomfort.  High indoor humidity can also lead to other issues like mould growth, dust mites, and damage to property, furniture, and electronics.

If you find yourself in this sticky situation, fortunately there are things you can do:

  • Check the Controller: Modern AC controllers or thermostats often have a ‘humidity’ or ‘dehumidify’ setting.  Ensure the controller is set correctly and functioning as it should be.
  • Regular Maintenance: Checking filters and ensuring heat exchange coils are clean can improve the efficiency of your air conditioner.  Sometimes a humidity issue can be resolved by simply completing an aircon service.

If you’ve tried these steps and you still feel like you’re in the middle of a jungle inside, it might be time to call for professional help.  Looking up an air conditioning repair service near me will help you find someone who can not only service but also repair your AC if needed.  They can assess your system, service the aircon, recommend repairs, and even advise if a replacement or supplementary dehumidifier is required.  Hopefully a standard air conditioner service is all that is needed, but good to be prepared!

Sign 7: Air Conditioner Short Cycling

There’s something reassuring about the predictable rhythm of an air conditioner at work.  Cycling in and out, keeping our climate just right.  But what if your AC seems to be dancing to a faster, more erratic tune?  If it’s turning on and off too quickly, you might be witnessing what’s called “short cycling.”

Air conditioners have regular cycles where they run, reach the set temperature, and then rest for a while before starting again.  However, if your AC is starting up and shutting down more frequently than it should, it’s a clear sign that an air conditioning service and possibly repairs are required.

There are a few common issues that could be causing the short cycling air conditioner:

  • Faulty Controller: Sometimes the issue isn’t with the AC units but rather with the controller or thermostat.  If the temperature-reading point is not reading the room’s temperature correctly it can cause the air conditioner to turn off prematurely.
  • Oversized Unit: If your aircon is too big for the area served, it might cool the room rapidly and then shut off, only to restart a short while later because the temperature rises quickly.  It’s a classic case of a unit that’s too powerful for its own good.

Short cycling isn’t just annoying; it’s very costly.  It causes AC equipment to wear out faster than it normally would and increase energy consumption, leading to higher power bills.  Preventing this is just one of the many ways to help extend the life you’re your air conditioner.

If you’re feeling a bit hot under the collar about this issue, keep cool and check these:

  • Thermostat Check: Ensure your thermostat or controller (if that’s where temperature is being read from) is placed away from heat sources like lamps or direct sunlight.  It’s also recommended to replace the batteries and check that it’s functioning correctly.
  • Filter Check: A dirty or blocked filter can restrict airflow, as discussed previously, causing the air conditioner to overheat and shut down.  Routine inspection, cleaning, and/or replacement of filters helps ensure smooth AC operation.

If your air conditioner continues its rapid on-off routine after these checks, it would be wise to seek out professional advice.  An expert can diagnose the underlying issue/s, complete an AC service, and suggest aircon repairs if needed.  Subsequent repairs may be in the form of recalibration, replacement of parts, or even considering a unit that’s better sized for the area served.

The Importance of Air Conditioning Service

Like many other household appliances, your air conditioner needs service, attention, and care.  Waiting for a complete breakdown before seeking an air conditioning repair service isn’t just inconvenient—it can also be costly in the short and long run.  This cost isn’t just limited to the aircon, but also applies to your health and the condition of your property.

Being proactive with air conditioning maintenance is an investment that really pays off.  Regular check-ups and aircon servicing can significantly prolong the life of your AC system and ensure it runs efficiently for as long as possible.  This translates into reduced energy bills and helping avoid unexpected repair costs and premature replacement.  The importance of air conditioning service cannot be overstated.


In this article, we’ve highlighted some key signs that your air conditioner might be crying out for some TLC: weak airflow, not cooling even while running, unusual noises, odd odours, leaks, unregulated humidity, and short cycling.  These aren’t just quirks; they’re clear indicators that something’s wrong and the air conditioning needs service and attention.

For the comfort of your home and the longevity of your AC equipment, it’s essential to prioritise the health and efficiency of your air conditioner.  Don’t ignore these signs; they’re your aircon’s way of communicating with you.  It’s wise to pay attention to the signs of an air conditioner service being required, for the health of you, your family, your workplace, your property, your belongings, and the AC equipment itself.

This results in wasted money via excessive power bills, increased aircon repair costs, and premature equipment replacements.

Learning how to clean air conditioner vents isn’t just a matter of aesthetics but an essential practice in supporting IAQ in house and the longevity of air conditioning systems. Attention to and commitment to ensuring air con vents are clean and functioning optimally allows them to perform as the unsung heroes they really are.

1b. Brief Overview of Different Vent Types

There are a wide range of vent types, with different functions and terms used to describe them. They come in an array of different shapes, sizes, and structures.


The first step is to understand the functionality of the main types of air vents:

Supply Vents

These are designed to supply air into a room. Supply air vents typically contribute to room temperature changes, making it warmer or cooler, depending on the air con set up.

Return Vents

These are designed to allow air to be drawn out of a room and return to the indoor unit. Return air vents contribute to the circulation and regulation of air throughout an entire HVAC system.

Exhaust Vents

These are designed for air to be extracted from an indoor environment, such as a bathroom or toilet. A fan is often used to draw the air out through the vent into the outdoors.

Fresh Air Vents

These are designed to reintroduce fresh air from the outdoors back into the indoor environment. They are typically set up with building ventilation, or can be retrofitted, and are subsequently maintained along with the rest of the HVAC system.


Air vents come in a range of different shapes, much like the range of ducted air conditioning brands:


These are compatible with building structures, fit nicely into walls and ceilings, but require more material for similar airflow to round vents.


These boast efficiency in air movement and are material-economical compared to their rectangular counterpart.


These are typically flat, low-height design, adapt shapes, can become rounder under pressure, and offer versatility in spatial requirements.


Vents also come in a range of different sizes, with numerous sizes available in each range and no one-size-fits all standard:

Small (range)
Medium (range)
Large (range)


In addition to these variations, differentiating the main vent structures is important:


These are often found on walls, ceilings, or floors, and typically made from metal. Grilles facilitate the flow of air without adjustable slats.


These often have slatted openings that can be adjusted, and typically made of plastic. Registers provide a degree of control over airflow and direction.

Ducted air conditioning is one of the most common types of air conditioning available.  It is found in homes and businesses worldwide due to its many benefits.  In some regions of the world, ducted air conditioning is a luxury.  In some regions, like Brisbane and Queensland in general, it’s almost a necessity for most buildings.

When looking at Brisbane air conditioning, here are some estimated prices for ducted air conditioning:

  • A small home typically involves a price range of $6,000-$12,000 for ducted supply and installation.
  • A standard 2-4 bedroom home may involve a cost of between $8,000-$16,000 for supply and install of ducted air conditioner.
  • A large 4+ bedroom/double-storey may vary from $10,000 – $20,000 for full ducted air conditioning installation.

Given the variety of factors involved and the wide range of pricing options available, it’s best to opt for an experienced specialist who can assist with quotes tailored to your specific needs.  Key considerations include space measurements, budget requirements, and personal preferences.

Consulting a ducted aircon professional will help you get the most out of your ducted air conditioning system without breaking the bank.  However, some background knowledge is helpful when discussing your needs with the experts.

Understanding the costs involved in a new ducted air conditioning system can be confusing.  It can be helpful to think about ducted aircon varying in price due to three main factors; ducted unit pricing, addition of AC zoning, and ducted install costs.  In this article we’ll explore these main 3 costs.

What is Ducted Air Conditioning & How Does it Work?

Firstly, it’s important start with an overview of what a ducted air conditioner is and how it functions.  Essentially, ducted air conditioning is a system based on the refrigeration cycle and designed to provide heating, cooling, ventilation, and conditioning of air in buildings.

Daikin ducted air conditioning components

Ducted split systems consists of two parts, the outdoor condenser and the indoor evaporator unit.  The condenser (“outdoor”) is typically located in a well-ventilated area outside, and transfers heat from the building to the external environment.  The evaporator unit (“indooSr”) is usually concealed in the roof or ceiling space and distributes cooled air throughout the indoor environment.

The two main units that make up a ducted system are connected by piping and cabling.  Then there are ducts that connect each room or space to the indoor unit.  The ducted aircon system can be controlled with a wall controller or remote control, as well as Wi-Fi controls available on modern systems.  In some cases, an AC zoning system may also be included.

Ducted reverse cycle air conditioning is a type of air conditioner which offers both cooling and heating capabilities in one system.  This reduces the cost of having separate devices for both functions.  With ducted reverse cycle aircon, the indoor environment can be kept at a comfortable temperature no matter what the outdoor climate is.

Commercial ducted systems are often designed to cool the workplace due to benefits of ducted air conditioning for a business, with other heating solutions such as heater banks being used for warming purposes.  However, ducted reverse cycle aircon is becoming increasingly popular in commercial spaces too due to its ability to satisfy both heating and cooling on demand.  This simplifies the heating, ventilation, and air conditioning (HVAC) system in a commercial building and provides maximum comfort for employees and customers alike.

Ducted air conditioners are primarily used for achieving temperature control and humidity regulation.  Air conditioning works by moving air over refrigerant-filled exchanger coils inside an indoor fan unit.  This fan circulates warm or cool air depending on whether it is a heating or cooling cycle respectively.  A condenser fan in the outdoor unit pushes air through this unit to reject heat into the outside environment.

Basic heat pump cycle

Refrigerant moves around the system in order to perform its conversion from high pressure to low pressure.  During its passage through expansion valves, refrigerant switches between vapour (gas) form and liquid form.  This distinguishes it from central air conditioning systems which use water as their local medium for heat transfer instead of direct refrigerant expansion (Dx).

New Ducted Air Conditioning Costs

The initial cost of a ducted air conditioning system is substantial and includes more than just ducted unit price itself.  Along with buying the indoor evaporator unit, outdoor condensing unit, and controller, you must also buy ductwork components such as flexible duct, supply/return air plenums and/or t-pieces.  Transporting these items to your home also carries a fee.

Furthermore, you will need associated components for new ducted AC install like pair coil or pipework, interconnect cables, insulation materials, and mounting equipment.  Electrical materials such as a circuit breaker and safety switch are necessary in most cases.  It’s also possible that you’ll need zoning gear including zoning controllers, modules, and sensors for individual room temperature control.

The cost of labour can be significant when it comes to ducted air conditioners as well.  Installers will typically be joined by technicians, apprentices, and an electrician in part to complete the job correctly.  The hourly pay rate plus superannuation for each team member should be factored into the total cost, along with any staff days off such as holidays or sick leave.

Calculating a ducted air conditioner pricing

Finally, there are business overheads like licenses, insurances, and advertising that contribute to the overall expense.  Clean up materials and rubbish fees can also pop up during an installation or replacement job.  As you can see, there are many costs that aren’t immediately apparent when it comes to a ducted air conditioning installation pricing.

Ducted Air Conditioner Unit

It’s easy to underestimate just how much goes into installing or replacing a ducted air conditioner.  However, if done properly with the help of a reputable installer, it can save you time, money, energy, and sanity in both the short term and long run.

The cost of a ducted aircon unit varies depending on the brand, size, and model that you choose.  It is important to calculate the size based on factors such as building usage, heat load, airflow requirements, and ceiling heights.  Most ducted units come with wired wall controllers or remotes as part of the package, so bear this in mind when considering prices.

Local suppliers may be able to offer competitive pricing due to wholesale buying and lower retail overheads.  Consider asking for any cashback offers or discounts before committing to a purchase.  Furthermore, quality often correlates with price so it may be worth investing in higher-end models from reputable manufacturers such as Daikin, Mitsubishi Electric or Heavy Industries, ActronAir, Panasonic, Toshiba, or Hitachi.

By taking the time to compare prices and research ducted AC models before settling on a purchase, you can save money on your ducted air conditioner system while getting top quality equipment.  You can also safe money in the long term if the best ducted aircon is chosen upfront.

Ducted AC Zoning

Ducted air conditioning zoning is an optional feature that can greatly influence the price when installing a ducted AC system.  From installation to upkeep and maintenance, the price of a zoning system can change dramatically depending on the size, brand, and features you choose.

The number of individual zones will depend on what size of zoning system you decide to go with.  Most controllers offer up to 8 zones as standard, though some extend up to 14 or even 27 zones with smart systems like iZone.  Each additional zone will add both material and labour costs.

When it comes to brands, there are many options available including Daikin and Mitsubishi Electric or third-party options like Polyaire (AirTouch) or All Air (iZone).  Quality may affect price but so do specific features featured in the system.  It’s worth shopping around for the best value for money before making your decision.

Ducted Air Conditioning controls

When looking at features, you should consider how much control you wish to have over each area.  Ducted air conditioning zoning control can range from basic on/off controls to individual room temperature control.  Additionally, there are various added extra functions such as Wi-Fi connectivity, touch screens, motion sensors, timers, and even whole home automation integration which can come included or as an additional cost depending on the model chosen.

Timing is also important.  Having your zoning system installed at the same time as a new ducted aircon system rather than down the line tends to be more cost-effective.  By investing time into researching all elements of ducted air conditioning zoning prior to investing money into purchasing one, you can make sure that in the end you’ll get the most out of this option for a reasonable price.

Ducted System Installation

When it comes to the cost of installing a ducted air conditioner, there are several factors that need to be taken into account.  The size, type and number of units, space available for components, the degree of difficulty during installation, and materials required all have an impact on the final cost.

Larger units are typically more expensive due to being three-phase power units (18kW and above).  They require additional electrical cabling and materials compared to single-phase units (17 kW and below), as well as additional labour for installation.

Due to their electrical nature, ducted air conditioners should not be installed by DIY or unlicensed contractors.  This poses a risk for extensive damage, voiding warranties and insurance claims, or worse – risking lives.  Therefore, it is vital to engage a reputable company with experience managing and performing installations.

The quality of materials and service can vary significantly from company to company.  Low upfront costs may seem tempting but could end up costing far more in the long run due to rogue tradespeople taking advantage of customers.  Unfortunately, these cowboys also often use low quality materials that fail earlier than expected.  A good quality installation will save money in the long run while providing peace of mind that the system is operating as designed with maximum energy efficiency.

Before determining whether ducted air conditioning is suitable for your home, you’ll need to make sure there is enough roof space for the ductwork.  If you’re replacing an existing system, the ductwork should already be in place and can be reused or modified as needed.  A pre-install site inspection can assess quality of existing and suitability to reuse existing ductwork with the new ducted aircon install.

It’s important to consider the locations of both the indoor and outdoor units when installing a ducted system.  Incorrect placement can lead to additional costs due to access issues or extra labour and materials needed.  The indoor unit should ideally be placed in a convenient spot near the return air grille, away from manholes and beams that could complicate future repairs.  It may cost more upfront, but it could save you thousands down the line.

Similarly, when it comes to positioning the outdoor unit, investing in an ideal location will pay off in the long run.  This unit is usually more expensive than the indoor one and acts as the powerhouse of the entire system.  If the condenser runs more efficiently, so does the entire system with potential savings on energy bills.  When placing it outdoors, try and arrange a shady, airy spot if possible and practical.

Man choosing a new air conditioner

What to consider when choosing an air conditioning unit in Brisbane

During the hot Brisbane summer, air conditioning is essential for ensuring comfort and productivity.  It would rarely be considered a luxury in QLD; nowadays it’s a necessity in most buildings.

With so many types of cooling available, it can be difficult to choose the right air conditioner for your home or commercial property.  Here are some points to consider:

Size Required

First, consider the size of your space and how it will be used.  Size required depends not only on area of the room/s, but also heat load.  Area and heat load are 2 of the most important factors that will determine the best fit for your Brisbane business or residential property.

Air conditioners come in different capacities and sizes.  If you buy an AC unit that is too large or too small, it could result in sub-optimal performance, reduced efficiency, and energy wasted.  Like Goldilocks, you want to find the one that is just right.  In air conditioning, this refers to a kilowatt (KW) capacity.

Capacity Comparison

When review KW rating, it’s important to look at the cooling capacity.  Air conditioners have a heating KW rating also, but AC units in Brisbane should only be compared on their cooling rating.

Some units can ramp up above their stated KW rating, but usually only for a short period of time (e.g. 30 minutes).  It’s not recommended to strain an air conditioner by continually demanding it work over its rated capacity.  Like anything pushed to its max, it will wear out faster and shorten expected lifespan, costing you more money in the long term.  This is especially true in the harsh Brisbane climate.

Climate Control

Smaller homes or offices may benefit from wall-mounted split-system air conditioners as they can provide direct cooling to specific areas.  They also provide area-specific climate control.

For example, an office server room might require 24/7 cool conditions to keep critical electronic equipment cool.  Meanwhile, a paper file storage room may require relatively mild conditions to accommodate the occasional visitor.

Larger spaces require larger solutions, such as ducted air conditioning.  Ducted air con works by circulating cool air throughout the entire property.  These are suitable for homes or workplaces where the indoor climate requirements are fairly similar throughout the area to be served by the ducted system.


The addition of ducted AC zoning should also be considered.  Zoning allows certain rooms or areas to be closed off, air flow to be adjusted, and/or temperature to be adjusted.  The level of control depends on the type of ducted zoning installed.

Brisbane air conditioning installers are everywhere, and residents are spoilt for choice when it comes zoning additions.  There are many finer details to consider when assessing zoning, such as standard constant zone vs bypass electronic constant zone.  It’s recommended to consult a ducted zoning expert for more advice on the differences.


You should also consider how often you will use the air conditioning.  If it’s only needed occasionally in one area, then a stand-alone budget wall split air conditioner may be suitable.

On the other hand, if you require constant cooling or use aircon majority of the time, then investing in a higher quality air conditioning system is worth it.  When reviewing higher quality brands, the decision often comes down to Mitsubishi Electric or Daikin in Brisbane.


As you can imagine, air conditioning in Brisbane is in peak demand in the warmer, summer months.  As a result, demand for new air conditioning goes up as the temperature heats up.  The lead up to Christmas sees demand reach an all-time high as everyone wants to be cool and comfortable for the holiday period.

Lead times for install become longer in response to demand.  Air conditioning suppliers also start to run short on certain sizes and/or models.  Stock shortages have been worse in recent years following COVID lock-downs, shipping containers delayed, and global economic factors forcing AC manufacturers to reassess how much stock they carry.

The cooler months are recommended when considering a Brisbane air conditioner.  This will give you a greater selection of AC units, shorter lead times, and better deals.  The temperature will also be milder, taking the pressure and urgency off the whole process.

From wall splits to ducted splits, package units to evaporative cooling units, it’s important to know what works and what doesn’t work.  Here is a brief overview of the most popular Brisbane air conditioning units that customers ask about:

Split Air Conditioners

Split air conditioners are a great option for smaller spaces requiring specific climate conditions.  These systems can be mounted on the wall, hung under ceiling, or stood on the floor.

Split systems usually consist of an indoor unit that absorbs heat from the warm air and transfers it to an outdoor unit via refrigerant gas.  An indoor fan blows the resulting air out into the room, providing cooling.

With a standard split aircon, the outdoor condenser unit rejects heat into the atmosphere and condenses the refrigerant gas into a liquid.  It then pumps the liquid refrigerant back to the indoor evaporator unit to absorb more heat.  This process forms a loop, known as the refrigeration cycle.

Ducted Air Conditioning

Ducted aircon systems work by supplying cool air throughout an entire property, rather than just in one room or location.  This makes them ideal for larger Brisbane commercial offices, warehouses, schools and such facilities.  The upfront cost of ducted air conditioning plus cost of ongoing maintenance should be weighed up against other options available.

Ducted systems are typically installed with the indoor concealed in the ceiling and the outdoor on the ground, wall bracket, or roof.  They utilise a series of ducts in the ceiling space to distribute cooled air throughout the building. These days, the indoor components are sometimes left unconcealed to create an industrial look.

Installing ducted AC in Brisbane

Brisbane ducted systems are popular because of the larger houses, in comparison with Melbourne and Sydney.   Population density is lower, so houses can be larger and there are more options available in terms of outdoor unit location.  Furthermore, because the houses are not as close together as many other major cities, standard noise from a ducted condenser is less of a concern.

Package Units

Package units are another popular option in Brisbane, as they also utilise ductwork.  These units consist of 1 large unit, rather than 2 in the case of the ducted system.

A package unit is 1 complete unit that contains both the evaporator and condenser coils.  The unit typically sits up on the roof (i.e. rooftop package unit), in a plant room, or down on the ground.

If a Brisbane HVAC technician could choose any air conditioner to work on, a Package Unit would often be their number 1 choice.  Why?  Well, just think about the other popular option; ducted.  Ducted indoor units are in the ceiling, and ceiling spaces get VERY hot, very quickly under the Brisbane sun.  Throw in tight spaces and humidity… Not where you’d want to be for an air conditioner service, let alone repair or install.

In comparison to ducted AC, package units are usually out in the open or in a nice airy plant room.  All components are easily accessible.  No wonder package units are gold to commercial HVAC tech’s!

Evaporative Coolers

Evaporative coolers are an efficient and cost-effective way to provide air conditioning in dry climates.  However, they don’t work well in humid climates such as Brisbane!

The reason for this is simple: evaporative cooling relies on the evaporation of water to create a cooling effect.  If the air is already saturated with moisture and no water can evaporate, no cooling will take place.

This means that in a humid climates like Brisbane, evaporative coolers will not be able to perform efficiently.  Additionally, too much humidity can lead to mould growth inside the unit.  This can lead to a whole range of health problems.

For these reasons, evaporative coolers are not suitable for Brisbane.  They should be avoided in favour of other types of air conditioners that do not rely on evaporative cooling.

When it comes to Brisbane air conditioning, there is no one-size-fits-all solution.  It’s important to consult with a professional who can assess your needs and recommend the best system for your home or business.

Maintenance of air conditioning units in Brisbane

Maintaining air conditioning units in Brisbane is essential for ensuring optimal performance and comfort.  Air conditioner servicing is just as important, if not more so, than the initial installation.

While there are many types of aircon available, the general principles are the same to ensure they keep running efficiently all year round. Here is a summary guide to Brisbane air conditioning maintenance:


While Brisbane air quality is better than many other capital cities, air conditioning filters are still essential for keeping your indoor air clean and healthy.  Not only do they trap dust, pet dander, and other allergens in the air, but they also help reduce odours and keep your AC system running at peak efficiency.

When a filter gets clogged with dirt and debris, it can restrict air flow to the air conditioner and cause it to work harder than necessary.  This can result in poor performance, higher energy bills, and even permanent damage to the system.  To keep your air conditioning system running smoothly, make sure that you pay attention to filter maintenance at a minimum.

Woman checking her air conditioner

It is recommended to check the filter/s every month or two at least.  If it is visibly dirty, remove, clean, dry, and reinstall.  If the filter is clean, it does not need cleaning.  Excessive washing of an air conditioner filter when not required will wear the filter media out quicker, shortening the lifespan of your filters.

If the filter is becoming see-through when you hold it up to the light, or damaged in any way, it is time to replace.  For wall split systems, these can be ordered from the manufacturer or via a Brisbane air conditioning company.

For ducted air conditioning filters, filters are usually made to measure due to the wide range of sizes used in Brisbane.  Even if they look similar, filters just 5-10mm out may either not fit in the return air grille at all or not fit as designed.

If AC filters are not cleaned frequently enough, are worn, or are too small, the air conditioning system cannot work properly.  Matter may bypass the filter and enter the indoor unit.  On the evaporator coil, bacteria, mould, and other such matter thrives in the moist conditions.  This can spread throughout the air conditioning system and indoor air.  This is certainly not healthy for the aircon or your health.

Other AC Components

Aside from the filter/s, inspecting an air conditioner on a regular basis for any visible signs of damage or wear and tear is essential.  Brisbane weather conditions can be relentless in Summer, and this puts a strain all AC components.

A quick inspection can start the process, using ears and eyes only, to check all components.  This hands-OFF check helps assess if there are any major issues with fans, blades, compressors, condenser coils, insulation, pipework, isolator, etc.

While there are some other easy air conditioner maintenance checks you can do yourself, it’s important to stay safe and know your technical limits.  If you notice any problems, it is best to contact a Brisbane HVAC contractor for further servicing or repairs.

Area around the AC Unit

If accessible, it is important to keep the area around each aircon unit clean and airy.  This involves keeping it clear from storage items, obstructions, debris, vegetation, and animal habitat.

Anything that obstructs AC unit airflow can decreased performance and efficiency.  This it can cause components to overheat and/or burn out.  Worst-case result is complete system failure.

With vegetation and habitat, it can provide a home to all sorts of animals.  In Brisbane, geckos are of particular concern.  Sneaky geckos frequently find their way onto printed circuit (PC) boards, causing death to the board and gecko.  Due to the electrical nature of modern day air conditioners, this often has a flow on effect and can take out multiple PC boards, sensors, fan motors, and capacitors.

You can invest in gecko deterrents and treatments offered by Brisbane air conditioning repairers.  However, there is no guaranteed way to prevent geckos from damaging your PC boards.  The applications also wear down overtime, particularly in response to gecko urine.

By following these simple steps, you can help to ensure that your air conditioning system is running efficiently and effectively all year round.  With the right care and maintenance, you can enjoy a comfortable home or office in Brisbane without having to worry about the heat.

How to save money on your energy bills with an air conditioner in Brisbane

When it comes to keeping your commercial building or domestic property cool in the Brisbane heat, air conditioning is essential.  However, running an air conditioner can be expensive and take a toll on your already rising energy bills.

Fortunately, there are several ways to help you save money on your energy costs while still enjoying comfortable temperatures inside.  Here are just some of the ways to save money when running your Brisbane air conditioner:

Energy Efficient Air Conditioner

The first step in reducing air conditioning running costs is to be sure to choose an energy-efficient air conditioner to begin with.  Look for a suitably sized system with a high energy star rating and/or EER rating.  This AC equipment will use less power and can help reduce your electricity bills.

It’s important to remember to install the correctly-size air conditioner upfront.  While a 2.5KW air conditioner will have a higher star rating than a 5.0KW, it’s going to draw excessive energy by never cycling off if installed in a room requiring a 5.0W.  Furthermore, it will wear out faster and cost more overall.  So, while saving on energy bills is important, we must be careful not to cause greater expense in other areas.

Temperature Settings

Making adjustment to the temperature settings on your air conditioner controller can help you save energy and reduce your power bills.  Even small adjustments can make a big difference.  For example, 1 degree can make a 5-10% difference to your energy usage.

In Brisbane during the summer months, it is best to set your thermostat between 24-26°C.  During the colder winter months, it’s recommended to be set between 18-20°C.

Keeping your home at these temperatures will provide comfortable temperatures inside while still keeping costs down.  Additionally, using fans or ceiling fans can help circulate cool air throughout the space and make it feel even cooler without having to lower the actual air conditioning temperature.

Routine Maintenance

Once an air conditioner is installed, maintenance become critical to keep it working as designed.   Scheduling regular maintenance services for your AC system can take the hassle out of remembering to book.  This can also help avoid the air conditioner becoming neglected until it’s too late.

Routine maintenance helps to ensure optimal operating conditions and improves energy efficiency.  This allows an aircon to use the least amount of power to generate the maximum cooling effect.

Given that more than 50% of running costs for Brisbane commercial buildings is attributed to the heating, ventilation, and air conditioning (HVAC) systems, a small improvement in efficiency can result in a huge money saving.  Preventative maintenance is a cost-effective option for Brisbane air conditioning systems.

Scheduled HVAC maintenance can catch minor issues before they become major.  This can save you significant time, money, and energy.  Maintenance also helps prevent downtime and lift the morale of your family (home or work). This can contribute to financial savings all around.

By following these simple tips, you can keep your Brisbane air conditioning requirements under control all year round.   Most importantly, you can stay cool during the scorching summer months while still saving money on energy bills.

Investing in an efficient air conditioning system and taking proper care of it can go a long way to helping you to stay comfortable and save money in so many ways.  For any assistance finding the best air conditioner for your needs in Brisbane, please don’t hesitate to contact us.

Summertime offers the best time to enjoy chilling on the beach with friends, picnicking at the park or backyard camping with your family.

But it could also be a frustrating experience for many people, with temperatures rising as high as 35 degrees in many cities.

While split air conditioners help you stay cool all the summer, they have a fair share of problems you may have to contend with.

Like any other electronic appliance, split air conditioners are susceptible to breakdowns and problems if not serviced regularly. The following are the top 5 problems of split AC units and their potential solutions.

1. Inadequate Cooling

One of the most common problems with split air conditioners is the lack of cooling. Split air conditioners are efficient and take a short time to cool down to the desired temperature.

However, if your split air conditioner isn’t cooling as quickly as it used to be despite being turned on for hours, it most likely has a problem.

A dirty air filter, condensate drain, or ice formation on the evaporator coils could cause your AC’s inadequate cooling. Air filters are intended to keep dust and debris out of the air conditioner.

They can become blocked and affect the efficiency of your air conditioner if they are not cleaned regularly. We suggest you clean your AC at least once every six months to prevent air filters from getting blocked.

2. Gas Leak or low refrigerant level

Gas leakage or reduced refrigerant level could be why your split AC is not functioning optimally. Refrigerant is a fluid or gaseous compound that absorbs heat from the environment, making your home cool.

Lack of refrigerant or gas leakage in your split air conditioner will affect its performance. Solving this problem may require you to check your AC indoor unit and outdoor unit and also look for areas of possible leakage points.

3. Compressor failure

Fixing an AC compressor

The compressor is a vital part of an air conditioner. It is located in the outdoor unit and controls the gas flow between the evaporator and the condenser.

A compressor failure could cause your split AC to stop working or reduce efficiency. To repair a faulty compressor in your split AC, clean the condenser coil, inspect the capacitor, and clean the outdoor unit fan.

You may have to replace the compressor if it’s damaged beyond repair.

4. Unpleasant odour when turning on the air conditioner

Another common problem with split AC is when you turn on your air conditioner; it begins to emit an unpleasant smell. This problem is common with old split AC that is not serviced regularly.

When dirt accumulates in the AC drainage system, it prevents water from flowing, leaving water on the AC drain tray.

You can resolve the issue by cleaning the drainage system or hiring a professional split AC repair service.

5. Problem with the thermostat

A  is an internal control unit that allows you to set the appropriate temperature according to your needs.

A thermostat breakdown will prevent you from regulating the temperature and may cause damage to the split AC unit.

You can set the thermostat to the minimum temperature or call a split AC qualified technician to help you resolve the problem.

Bottom line

Regular maintenance of the split AC can help ensure its longevity. If you notice any of the problems highlighted above in your split AC do not hesitate to resolve them as soon as possible by hiring a split AC professional to enjoy that satisfying coolness.

Summer comes with a lot of unforgettable thrills and fun for many people. From longer afternoons to the warmth of the blazing sun, summer provides the perfect cover for families and friends to unwind and bond.

However, summer is a period when you would have to deal with higher temperatures, and not many people can stand the heat for long. Sleeping, working, or exercising can become extremely discomforting for many, especially in hotter regions.

As a result, the use of air conditioners would make your summer more comfortable and enjoyable. Air conditioning has transformed how we live and work, but the comfort it delivers comes with a price.

With rising energy costs, you must educate yourself to save money while staying cool during summer. Here are some tips you can use to enjoy a comfortable summer.

1. Check the performance of your Air Conditioning System

Air conditioning in summer

Start by testing your air conditioning system before the onset of summer. Since it is likely you may not have used it in a while; you should check its performance to know if it is working fine.

Checking early helps you detect and resolve any problems right ahead of time before facing the blazing heat of summer.

2. Keep Air Filters Clean

Ensure you keep your air filters in good condition. With time, your central HVAC air system will become clogged with dirt and particles, making it less effective in lowering indoor temperature.

Keeping your filters clean allows air to pass through easily and improves indoor air quality. More so, keeping your air filter clean can also reduce your unit energy consumption by up to 10%.

If you have a permanent electrostatic filter in your HVAC unit, you should clean it every 30 days.

3. Plan an HVAC Tune-Up

Consider an HVAC tune-up in addition to checking your air filters for maintenance. Hire an HVAC technician to help diagnose and repair any defect before it degenerates into bigger problems.

Schedule maintenance with your HVAC technician at least once a year. Your technician should be able to address heating and cooling functions to ensure your HVAC unit is ready for optimal performance come summer.

4. Set up a programmable thermostat

While adding a programmable thermostat may cost you some bucks, it is worth it. By setting up a programmable thermostat, your air conditioning system could function more efficiently.

The device allows you to organize your home’s air conditioning operations. It does this by allowing the temperature to rise between 5-10 degrees while you are away and return to your desired temperature when you return.

5. Seal cracks and openings in doors and windows

Small gaps and cracks are as tiny as an inch and can let in as much air as a 2.4-inch diameter hole. Use air caulk to seal gaps to prevent warm air from leaking into your home.

You can try out the dollar bill test to know if the gaps in your walls are large enough to leak air into your homes.

6. Install drapes and blinds

Cover your windows with light-coloured curtains or metal blinds to keep the sun’s heat out of your home. Once the sun is reflected away from the interior of your home, your air conditioning unit will have less work to do, prolonging its useful life.


Keeping your home as comfortable as possible is crucial for an enjoyable summer. Following these tips would save you money and keep you cool all summer long while protecting your air conditioner.

The compressor makes up the heart of an Air Conditioner’s cooling cycle. It is located outside the air conditioning unit and is responsible for cooling the refrigerant. A faulty AC compressor may lead to an increase in energy consumption. The air from the air conditioner may become hotter than normal due to poor refrigerant circulation.

The compressor has to function optimally for your air conditioning system to provide a good cooling effect. But how does an AC compressor work? What are the functions of an AC compressor? Let’s find out!

Here is how an AC compressor work

Your air conditioner compressor helps to cool the refrigerant. After leaving the evaporator of your ac air conditioner, the liquid refrigerant transforms into a low-pressure gas after absorbing heat. The refrigerant absorbs the heat from the room in your ac evaporator since heat rises to occupy cooler areas.

The gaseous refrigerant enters the compressor, which cools the hot refrigerant. Here is where your ac compressor works its magic. Firstly, it compresses the gaseous refrigerant into a liquid by increasing the. The AC condenser coils absorb the heat from the gaseous refrigerant. The cooling process continues as the refrigerant is further cooled before the now liquid refrigerant is fed into the evaporator coils of your air conditioning system.

The heating and cooling loop of the refrigerant continues as long your air conditioner is turned on to ensure your home stays cool and feels comfortable.

What are the functions of an air conditioning compressor?

Air conditioner model

You have seen how an AC compressor guarantees proper home or office space cooling. Here are some of the primary functions of your air conditioner compressor.

  • Transfer of heat

The AC compressor helps push the gaseous refrigerant to the condenser coil outside the air conditioner. The AC fans blow the cool air outside over the condenser coils and extract heat from the gaseous refrigerant before transferring it to the outside air.

  • Transforms the hot refrigerant to a liquid

As the compressor helps in cooling the refrigerant, the hot gas condenses into a warm liquid passed at high pressure to the expansion valve. The warm liquid then turns into a cool and low-pressure liquid before entering the evaporator coil.

How would you know if your AC compressor is working?

Your air conditioner compressor is a highly essential part of your AC system. Your AC compressor must function properly for effective cooling. However, the compressor may develop a fault as the air conditioning system ages or due to poor maintenance. One of the signs of a faulty ac compressor is an abnormal change in temperature or airflow. The leakage of refrigerant or moisture around your air conditioning unit is another sign of a faulty compressor. You may hear strange noises from your AC unit indicating that the ac compressor may be faulty.
