The benefits of servicing your commercial air conditioning systems cannot be overemphasized. Most business owners have had to spend more on energy bills and repair costs because of not servicing their commercial air conditioners regularly. But how often should you service your commercial air conditioning? Why do you need to service and maintain your commercial air conditioning? Find answers to these questions and more as you read on!

How often should you service your commercial air conditioner?

The average life expectancy of commercial air conditioners is about fifteen to twenty years. However, your commercial AC may not reach its maximum age if you do not service it regularly. Air conditioning systems used for most businesses should be serviced multiple times per year. The timeframe for servicing commercial air conditioning systems depends on several factors.

One of the primary factors that may determine how often you should service your commercial air conditioner is the operating environment of your business. If you run a manufacturing industry business, your air conditioning system may need to be serviced three to six time a year (every two to three months).

If your business is close to an area with lots of construction activities, or it is located in a place prone to pollution, you may have to service your air conditioner every one to two months. It would be best if you also cleaned or possibly even changed your commercial air conditioner filters every few services (e.g. if they are disposable).

Why you should service your commercial air conditioning systems

Your commercial AC has several components that work together to make your business environment comfortable. Hence it is critical to service the air conditioner system for optimal performance. Here are other reasons why you should service your commercial air conditioner:

Find out how long the HVAC business has been open

Almost every day, a new HVAC business opens its doors. According to Investopedia, only 50% of new businesses will still be in business five years after their launch date. This is true even though many new HVAC businesses have the potential to be successful. So, at the very least, you want to ensure that any HVAC contractor you work with has at least five years of solid work experience in your area.

In the other hand, you don’t want to hire a contractor to do a job and then find out they can’t fix problems or take care of the equipment they set up for you. As an article in Forbes magazine mentions, if inexperienced contractors spot a problem, it may not yet be in their repertoire to fix the damage in question. At this point, your HVAC contractor may refer you to someone else.

Safe and Approved

Choose an air conditioning contractor whose technicians have undergone drug testing, background checks, and the earlier requirements. It would be best if you also looked out for certifications. These certifications let you know that the company you’re working with is one of the best in terms of quality and customer service. Most HVAC companies put their license number on their website and other marketing materials. Do not be afraid to ask the company for their license numbers, perform background checks and any other testing or safety measures that will help protect your family and property.

Check for Reviews and Referrals

One of the best ways to find a good HVAC contractor in your area is to ask around. Review sites like Yelp, Angie’s List, and Home Advisor help people pick HVAC companies based on how well they’ve done in the past. You’ll find that most reviews written by past customers are honest and fair. If they got great service, you’d be able to tell from their ratings. If something goes wrong, they usually aren’t afraid to say so. Listen carefully to the stories of homeowners whose homes and HVAC systems are similar to yours.

No home inspection, then don’t use their service.

If a contractor is unwilling to go to your home for measurements and a comprehensive assessment, you should not hire them. Before giving you an air conditioning installation cost or replacement, a contractor should visit your home to look at your current system and measure it. After a thorough inspection, your technician will decide what size and type of unit are best for your home. Your ducts and insulation must be looked at to find the best fit.

Check for Pricing

When looking for a good HVAC contractor, you may want to consider how much their services will cost. Before a contractor starts working on your project, transparent pricing lets you know exactly how much you will have to pay. You should also find out if a contractor charges by the job or by the hour. Good HVAC contractors give you a clear price quote before they start the job and never charge by the hour.

Every twelve months is the best time to service your air conditioner, and the best season to do so is just before the change of any season.

When you buy your first home, you start to think about many things you didn’t know before you rented or leased it. Now, you worry about how much it will cost to water your yard. You must think about mowing, pulling weeds, tightening loose cabinets, weather stripping, caulking bathtubs, and servicing your air conditioner, including your home’s air conditioning system.

Since it’s getting warmer, it makes sense that many people are thinking about their air conditioners. Should they be taken care of regularly, and how often and when? After all, you don’t want your air conditioner to stop working during the summer.

Let’s understand what maintenance is all about

Air Conditioning Maintenance Technician


Most heating and air conditioning contractors offer this service, but the standard of service may vary. Depending on the season, your air-conditioning technician will usually have a list of things to check, test, clean, and adjust your cooling or heating system. This level of maintenance goes beyond the simple things you should do every few months on your own, like changing your air filter and making sure your outdoor unit is clear of anything that could block it.

During your air-conditioning maintenance appointment, your technician may make changes that help your system run better and use less energy. But there may be broken parts or major problems with your air conditioning system. If so, you may need to schedule a service to fix or replace a part.

Am I Supposed to Maintain My AC?

Your home’s air conditioning unit needs to be taken care of, just like your car or heating system. Since you’ll need your air conditioner the most in the summer, we recommend getting it serviced in the spring, when the weather is still nice enough to live without it.

Another common question from our customers is, “How often should I have my air conditioner serviced?” We recommend getting your air conditioner and heater serviced once a year. When the spring comes around again, you can turn it on and see how well it works.

If everything is working well, you don’t have to call a technician to change the air filter because you can do it yourself. To do this, find the slot on the unit where the filter goes. Slide-out the old filter and put a brand-new one in its place. Remember which side of the air filter should be on the outside as you do this. Before changing the air filter, read the manufacturer’s instructions about what kind of filter to use and how to change the old one.

When should you call a maintenance technician?

If you turn on your air conditioner and it makes strange noises or doesn’t blow cold air, you should call a professional as soon as possible. You don’t want to run your unit when something is wrong because it can lead to greater damage, where you’d have to buy a new one when a simple repair is all that is required.

Infography about 10 reasons to service an air conditioner

Failing to arrange a proper air conditioner service is more common than you may think in most Australian households.  This is because people think that AC maintenance can be costly, and the unit may still function without being attended to or even full repaired in some cases.

Please don’t make that mistake!  Your air conditioning system can develop serious problems if you just wait until aircon repairs are required.  You will likely need to pay more in the long run and your system won’t reach its full life expectancy.  Also, you will not be enjoying the full AC benefits as the system will fail to operate at maximum capacity.

If you are still wondering what are the reasons to service an air conditioner, even if it is still operational, keep reading.

Improve indoor air quality

Your air conditioner unit may be clogged with dust and dirt, or even worse, bacteria and mould.  You and your family could be breathing in this contaminated air without even realising it.

This can lead to health issues, especially if someone in your family is asthmatic or suffers from   allergic reactions.

If you carry out air conditioner repairs and perform routine AC maintenance, then you will improve the air condition for you and your family.  This creates a healthy and safer indoor environment.

Reduce airborne allergens and bacteria

By servicing your air conditioner you will help ensure a healthy life for your family, as a clean air con and clean air filters can lead to dust-free and bacteria-free air.

Many air conditioners used nowadays include air purification and filtration systems.  These are based on technologies that have been proven to be highly effective in helping to reduce viruses, bacteria and particles in suspension just by the air recirculation itself.

You will not enjoy those benefits if your AC is poorly performing because of inadequate aircon servicing.

Breathing clean air

Reduce the risks of diseases

Health and many diseases related to air conditioning have to do with poor air quality.  You can avoid these with regular servicing and HVAC maintenance.

Remember that the common cold, sore throat and tonsillitis can developed if you deny quality air to your family by not servicing your AC units.

Improve aircon performance

With service and maintenance, the air conditioner’s high performance will be ensured.  What is the point of buying the best air conditioner on the market if it won’t be working at its maximum capacity?

Also remember that despite the type of air conditioner you have, all of them need regular maintenance and service.  There are no exceptions.

Air Conditioner Performance

Improve energy efficiency

A regular aircon service will guarantee that your air conditioner runs at optimal capacity.  Remember that an AC may lose up to 5% of its efficiency each year if you do not properly service it or perform regular maintenance.

Keep in mind that high efficiency means that your aircon will perform better and consume less energy.  It will also be able to cool down or warm up a space much quicker.

Increase the life of an aircon system

The life span of your air conditioner depends on the size of the area it provides heating or cooling to, as well as other factors.  The average for a home air conditioner is 10 to 15 years. Now think about how that number could be halved without regular air con cleaning, servicing and maintenance.

It can be compared exactly with how your body functions.  If you do not exercise regularly, eat healthily, and check on your health every now and then, your life expectancy may decrease.  On the flipside, if you check on your health regularly and maintain yourself with a healthy diet and exercise then your life expectancy may increase.

Air conditioners work in much the same way.  You need to replace the damaged parts, clean it and make sure it’s working as designed on a regular basis.

Switching the air conditioner

Identify problems before they occur

You need to consider that it is not easy to identify an AC problem just by looking at the unit.

When you call an air conditioning contractor for maintenance, they will open up the units and do a comprehensive check.  This way, they will be able to identify any problem internally before it gets worse and causes more major, costly aircon repairs.

Or even better, by performing proper AC maintenance, there will be little to no room for a problem to even occur.

Reduce breakdowns

Premature breakdowns may occur if you do not perform maintenance regularly and service your air conditioner.  Remember that small issues that are not resolved in time may turn in the bigger problems that will surly cost more to repair.

If you left those aircon problems untreated it can lead to damage of the whole AC unit.  In the worst-case scenario you will end up having to buy a new air conditioner.

Keep you warmer or cooler all year

Without aircon servicing, air conditioner performance will be poor.  This will lead to the air conditioning system failing to condition the space to the desired temperature.

This can occur even when using your air conditioner in its max setting.  The AC will keep drawing power and try to perform, but will just be using excess electricity and be worn out faster.

Furthermore, what is the point of getting air conditioning if you will not support it performing as it should?  Do not wait too long to service your aircon and guarantee high performance.

Broken Air Conditioning

Save time and money

While you may think air con cleaning and servicing is expensive, you do not know how expensive it can get if you don’t pick up and solve issues in time.  Small damage may become huge if you do not service, repair or replace components soon enough.  In the long run, it will end up costing you more.

So, if you want to save money, keep track of when you need to perform maintenance or service to your AC.

Remember that preventive maintenance reduces the need for repairs in the future.  It can prevent permanent damage which would cost you more as you may end up needing to buy a whole new air conditioner.

Also keep in mind that for you to maintain the aircon warranty, you need to service the units regularly from day of installation.  If you fail to comply, your warranty may no longer be valid.  This means more money if your air conditioner has a manufacturing flaw.

Air conditioning savings

Remember that calling the experts to service your air conditioner will always be the best idea.

Imagine, out of nowhere, your air conditioner stopped working. You wonder what has happened, but you have also never done any cleaning or maintenance on the air filters. The good news is that it is on you. You have the ability to prevent this from happening.

Air conditioners are just like any other device at home. You need to clean it regularly to get the most out of it and make it work as designed.

Given that filters are one of the most important parts of an air conditioner, they have to be maintained correctly in order for an AC system to work properly.

Remember that poor maintenance, or even worse no maintenance at all, may increase electricity consumption. Also, it can deteriorate the whole air conditioning system faster than normal. So, if you want a long, energy efficiency life for your air conditioner you should clean and maintain it regularly.

Find out how to do it and how regularly you should do this.

How do I know that the air filters need a deep clean?

It is better not to reach a point where you can see or feel that your Air conditioner needs cleaning or maintenance. However, if this is your situation and it is already too late to prevent it, look for the following signs:

  • The heating or cooling cycle of your system is taking longer than usual.
  • The filter has already been in use for more than several months without attention.
  • You notice dust in the air and inside your home in general.

If any of these sound familiar to you, please clean your air conditioner filters.  If the case is extreme, you can always contact our team of air conditioning experts to help you with air conditioner maintenance.

What are the consequences of lack of aircon filter cleaning and maintenance?

Lack of cleaning

A primary consequence of not cleaning or changing your filters is a performance reduction, meaning the system won’t work as well as it is designed to.  You may notice a decrease in the air flow and the air conditioning temperature won’t be quite right.

Dirty filters will often result in an increase in electrical energy consumption, as the system has to work harder to get the room to the desired temperature.  This means your power usage will be higher and cost you more money as a result.

You may also hear an increase in noise from the air conditioner and even notice a bad smell coming from it.

For this reason, it is fundamental to pay close attention to filters and perform proper maintenance when necessary.

Basic maintenance of the filters is simple and easy to carry out.  Furthermore, the benefits are huge compared to the problems that not doing it can cause.

Remember that the main function of air conditioning filters is to prevent impurities, particles, germs and all kinds of harmful elements from entering the system and spreading through the indoor environment.

Lack of maintenance

Consequences from lack of maintenance are more serious.

When filters are in a very poor state, the indoor unit cannot move the air sufficiently and components of the system can literally freeze up. This happens because the system cannot dissipate cold into the environment.

If the indoor unit freezes up and the system is switched off for safety reasons, the ice will eventually defrost and all the water will drip and cause the drain pan to overflow.

It is also possible for dirt from the dirty filters to catch in the fan barrel and evaporator coil so that the air expelled will be completely dirty.

But the worst consequence of them all is compressor failure. If maintenance of the filters is postponed too much and they are left in an extremely poor condition, this can affect the compressor significantly.

The compressor is one of the most important and expensive components of an air conditioning system. If we have very dirty filters, the refrigerant cycle can be affected and cause excess liquid to reach the compressor (referred to as floodback). Replacing the compressor can be the most expensive repair for an air conditioner, therefore its worth considering if is better to do a full replacement or do the repair.

How to clean your air conditioner filters

Filters are normally made of polyester and are the first protective barrier for an air conditioning system.

Over time, dust particles tend to accumulate in filters. For this reason, cleaning will help you improve air quality and reduce power consumption of the appliance.

Cleaning it is not hard, but it depends on the air conditioning system you use.

How to clean the air filters from a Split Air Conditioner

Cleaning Split Air Conditioners is easy. You just need to take out the filters from the unit and rinse them with water.

Never use strong cleaning products that can be harmful for the filters. Just use your hands to wash the dust out of them. Let them dry for some time and then they are ready to go back into the unit.

How to clean the air conditioner filter from a ducted air conditioner

The process is very similar to cleaning the ones from the Split Air Conditioner. The main difference is the location.  Also sometimes the filters are not washable, but disposable.

You will realise what kind you have if the material is different. In this case, you will need to replace them for new ones rather than wash them.

How regularly should I clean the air conditioning filters?

It is recommended to check your air conditioner system every two to four weeks and clean filters whenever dirty.

It also depends in the environment in which you live. For example, if you live in the city where there is a lot of pollution, you should do it more regularly than if you live in the suburbs.
