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.

What is the better AC for your home?

Typically, you can pick from four types of air conditioner: window AC, split AC, portable AC or ducted AC. Which one to choose depends on the ease of installation and the capacity you need from your unit. Let’s briefly review the characteristics of each:

  • Window Air Conditioners: A window air conditioner is the simplest type of AC unit. It’s a single unit with all of the parts and components contained inside. The unity is installed in a window (sometimes in a wall) and connects to an electrical outlet.
  • Split Air Conditioners: This type of air conditioner is split into two units, hence its name. A unit is installed in a wall into the home and the other outdoor expels the heat gathered from the indoor system.
  • Portable Air Conditioners: It is a mobile unit that does not require definitive installation, although it does need a power supply point.
  • Ducted Air Conditioners: In this system, the air is sent through ducts from a central location to hear and cool all rooms of the house at the same temperature. Usually, the unit is in the ceiling.

Cooling Capacity

To know if an AC unit has the correct cooling capacity for your house you should know the BTU capacity of the product. BTU is the acronym for British Thermal Units and it is the measure of the amount of heat that the appliance can extract from a place.

To calculate the number of BTUs that your home needs you must use the following formula:

Room volume: Length x Width x Height = X, then divide X by 2.

Example: Length 3m x Width 3m x Height 2m = 18m / 2 = 9m.

With the answer obtained 9, it could be said that between 9,000 and 12,000 BTU is required. However, the BTUs needed may vary depending on weather conditions, the number of people in the home, and other factors. To make a correct decision, we recommend you have the advice of an expert to receive personalized attention.

Think about energy efficiency

The last models in the market have energy efficiency programs. It is a key point in your choice because this feature will influence your energy bill. It is also essential to keep in mind that the more efficient your AC unit is, the less impact its operation will have on the environment.

According to statistics of 2020, 63% of people in Australia use their air con during the warmer months and the Aussies keep their unit running for 6.3 hours per day on average. The overuse of aircon units provokes a response like the one that Fox News documents in New York, where during the high temperatures that North America faces the people are willing to ditch air conditioning to reduce carbon footprint and climate change.

When it comes to air conditioners, the debate about whether or not to cover your unit never comes to an end. One side says that air conditioner units are made to be outside and don’t need extra protection, so covering your unit is more likely to hurt it than to help it.

The others tend to take the “better safe than sorry” approach to AC protection and focus on keeping the air conditioner’s efficiency up. Since the weather is more unpredictable than ever, you should know both sides of the argument to make a good choice.

Does it help to cover your AC unit?

Air conditioner cover

The AC industry has been debating whether or not you should cover your AC unit in the winter. In theory, it makes sense. If you don’t live where it gets hot in the winter, you won’t need your air conditioner, so why not cover it up to protect it from the weather?

Many air conditioner experts say that you don’t need to cover your air conditioner because it’s made to handle bad weather like rain, wind, snow, and ice. Even though that may be true in ’97, there are times when you should cover your air conditioner unit.

Air conditioners are made to work in harsh conditions.

Air conditioner units are made to work outside to handle any weather, even the cold winters in Minnesota. The condenser, the hard box on the outside of the unit, has a finish that will last for a long time. The condenser is made to last through rain, sleet, snow, or hail. The coils in your air conditioner are also made to work in harsh weather.

Most air conditioner units don’t need to be covered when they’re not in use because they’re made of good materials and have a good finish. Most air conditioner manufacturers say that you shouldn’t cover it. Even so, many people think it’s a good idea.

When should you put a cover on your AC?

Cover your air conditioner if a snowstorm is coming.

Frozen air conditioning

People, where snow is common, should follow the same advice: take a few minutes to cover your air conditioner if you know a blizzard is coming. Keeping the extra snow out of your air conditioner can help, especially if the temperature rises above freezing during the day and then drops below freezing at night.

Wrapping it Up

Most people probably don’t need to do anything more than cover the top of the unit to protect it from falling debris. Putting a piece of plywood on top of your air conditioner is simple. Keep in mind that the location and surroundings of your home could be the only thing that makes you decide to cover your unit completely. You might have other reasons for covering the unit for the season.

Covering an air conditioner in the winter might help it look newer for longer, but it’s unnecessary. Your air conditioner was made to withstand the weather, so you don’t have to worry about it this winter.

Work productivity remains an utmost concern for several business owners. Many employees are required to be productive regardless of the working conditions.

However, research has shown that a worker’s productivity reflects the kind of working conditions they are subjected to.

While there are several ways to enhance work performance, having a good air conditioning system offers a good way to enhance workers’ productivity. A comfortable working environment is crucial to employee performance, and proper air conditioning helps provide such comfort.

The following are some of the ways air conditioning can improve work performance;

Exhausted female worker

An employee can only be productive when they’re healthy. A functioning air conditioning system has several health benefits that enhance employee productivity. They include:

  • Improves respiratory conditions: Airborne particles are common in the workplace and may likely cause respiratory illnesses. Similarly, gases and fumes from the outer surrounding may also enter the office apartment. A good air conditioning system helps circulate clean and fresh air by removing stale and heavy particle air.
  • Faster metabolism: An air conditioning system helps reduce the office’s temperature to a level that promotes faster metabolism in employees.
  • Reduces the pressure on the immune system: Germs spread faster in poorly air-conditioned rooms. An air condition unit provides the right temperature that mitigates the spread of germs.

2. Enhances worker’s comfortability

Several factors play a significant role in workers’ productivity. However, comfort in the workplace has remained an integral aspect of performance.

Research has shown that workers are more excited to work when comfortable. While there are numerous ways to improve employees’ comfort in the workplace, installing a functional air conditioning unit is very crucial.

Office temperatures have a strong connection to workers’ mood and productivity. For example, there is a difference between an office with a comfortable temperature of 74 Celsius to a stuffy 80 degrees.

A proper air conditioning unit goes a long way in enhancing employee comfortability and improving productivity.

3. Stable office temperature

An office environment with a stable temperature helps to maximize performance. Workers love a stable office temperature.

Coming to work each day to meet varying temperature levels can be quite unsettling. While there is a debate on the ideal work temperature, studies have shown that a temperature of 25 degrees Celsius is best for workers’ productivity.

An office apartment would need a good air conditioning system to keep temperature levels stable at the workplace.

4. Ideal humid temperatures

Aside from heat, humidity is another factor that unsettles many employees. Air conditioning systems with inbuilt humidifiers allow for humidity control.

Research shows that the ideal relative humidity of the workplace should be between 40-60%. Low humidity may cause itchy or dry skin and increase workers’ vulnerability to cold and infection, resulting in low work performance.

Workers perform best when they are relaxed, healthy, and stable. One of the best ways to enhance workers’ productivity is to ensure they are comfortable in their workplace.

With a proper air conditioning system, business owners and executives can improve the health and comfort of their workers, which helps to promote productivity.

High humidity levels in the home can be pretty unsettling. It often leaves you sweaty and uneasy.

High humidity and moisture levels pose a serious problem to your home’s structure and surfaces in severe cases.

For instance, high humidity can destroy paintings, wood, siding, and insulation in your home. Similarly, your home becomes prone to allergens and pollutants like dust, mold, and mildew, which can be devastating; to your health, especially if you are suffering from any pulmonary condition or asthma.

What is the ideal humidity level in your home?

The ideal humidity levels vary from one room to another. However, a level between 30 and 40 percent humidity is generally suitable for keeping your home warm and comfortable in the winter. Humidity levels between 50 and 60 percent are typically ideal, even on the hottest days of summer.
