Why Is It Important To Regularly Service Commercial Air Conditioners?

It’s estimated that, for every year you fail to conduct commercial air conditioning maintenance, the efficiency of your system drops by approximately 5%. This in turn affects operational costs, while neglect can also lead to expensive repairs and even replacement. Therefore, it’s important to have your air conditioner regularly serviced – we recommend a major service once every 12 months. Apart from performance, there are other reasons that your business’s air conditioner should be regularly serviced.

benefits of commercial air conditioning systems


Cool temperature

Perhaps the most obvious benefit associated with air conditioning installation is temperature regulation. In a commercial environment where machinery, equipment, and people coexist, it’s risky when temperature increases to dangerous levels. With commercial air conditioning system in place, you can maintain the temperature in your workplace at a more comfortable level both for you and your employees. Ever had one of those days when everything seems to drag on just because it’s hot? High quality air conditioners can fix that! When your employees are comfortable, their minds are clear and they’re always ready to tackle their tasks for the day.


Reduced energy bills

Hesitant to replace your old and outdated HVAC system because you think that means having to spend much more on commercial air conditioning installation? You must be getting the wrong idea about modern air conditioning services! Nowadays, Brisbane commercial air conditioning systems are built to be environmentally friendly and energy efficient. That means that by getting rid of your old system, you don’t only cut your energy costs but you also reduce your business’s carbon footprint.

Better productivity

You know how hard it is to concentrate on getting your work done when you’re feeling too hot. Working under extremely hot conditions makes you and your employees inefficient and less motivated compared to when there are air conditioners around. With air conditioning systems, you can achieve optimum temperature levels and help boost your employees’ productivity no matter how hot it gets outside. That’s scientifically proven! In fact, according to the Association for Psychological Science (APS), people have a harder time being productive when they’re feeling too hot. Workers who are working at a comfortable temperature also tend to be much happier, so don’t think twice about installing air conditioning units in your workplace or swapping out your old HVAC system.

Less noise

You know how noisy electric fans can get sometimes. If you need some cool air in your workplace but don’t want to be distracted by noise, go for commercial air conditioning. Since modern commercial air conditioning units are very quiet, you can hardly notice they are cooling the air around your workplace. Air conditioning systems aren’t as distracting as electric fans but they make the ambiance in your workplace so much better! Not only that–typically, doors and windows are closed off to air conditioned rooms so less noise enters your office, keeping it cool and quiet.

Go green

Are you a business owner who has taken the time to reduce your paper waste and greenify your office in other ways? Then your commercial air conditioning system should be your next step towards greenifying your workplace! When you upgrade your air conditioning system in the office, you are helping your business engage in more environmentally friendly practices. Ask Sun City Air conditioning specialists about programmable and smart thermostats to help you control your office’s interior environment.

Employee health

Ever heard about “sick building syndrome?” When the air inside your workplace has quality problems, your employees start to feel sick for no apparent reason. Without air conditioning installations in your workplace, the carbon monoxide in the parking garage located near your building might easily infiltrate your indoor air or may cause your old HVAC to circulate dust and debris through your duct network. You know how old air conditioning systems are often the victims of dirt and dust buildup. When this happens, particles end up traveling throughout your HVAC vents and contaminating the air inside your office. And what does contaminated air often result in? Illnesses such as asthma, allergies, and more. With a new air conditioning system, your workers don’t only get to enjoy clean air but also stay healthy.

Simplified maintenance

Repairs for older air conditioning systems can be very expensive. Unfortunately, if you haven’t been keeping up with your maintenance, or if you bought a building with an old system, you may be facing some costly repairs down the road. We’re certain you wouldn’t want repairs involving replacement parts end up costing your business thousands of dollars. When you invest in new air conditioners, all you need to do is to make sure that they are maintained on schedule. It’s very simple.

Frequently Asked Questions

How can I save energy when using an air con?

When the weather is hot, turn on your air conditioner early rather than work it harder once your home warms up. It also helps adjusting the louvres on split systems so they disperse air downwards when heating and upwards when cooling. It is best to check the energy star labels of your air conditioners before you buy–the more stars they have, the more energy efficient they are.

My commercial air conditioner is more than 10 years old. Should I get it fixed or replace it?

If your air conditioner has not been keeping up with its service maintenance, it is more expensive to have it fixed than replace it. Contact your trusted air conditioning services provider to know how much it will cost you either way.

What is ducted air conditioning?

ducted air conditioning system refers to one that delivers cool or warm air from an external fan into multiple rooms through ducts located in the ceiling.

Why is our meeting room always hot?

In a commercial setting, fluctuating meeting room temperatures are a common problem. The reason being is the changing heat load in meeting rooms.

People generate heat – so you can understand why the heat generated by two people is vastly different to that generated by ten or more.

The solution is to have dynamic and reactive cooling in the meeting room. This is commonly done by means of installing a separate supplementary system or by having thermostatically controlled variable damping of air supply.

Our office air conditioner is broken - who would pay to have it fixed / replaced?

Under most commercial leases routine servicing and maintenance are for the tenants account. This includes servicing, filter cleaning and replacement, and maintenance / replacement of controllers.

Capital repairs and system replacements are normally for the landlord’s account. This ranges from major repairs, like compressor replacements through to replacement of a system beyond economic repair.

We have seen leases where the tenant is responsible for all costs – such that they are required to hand an air conditioner back to the landlord at the end of the lease in the same condition as it was handed over at the start of the lease.

In all cases you should read your lease to determine who needs to pay for what.

Can I switch my air conditioner off at the powerpoint or at the fuse box?

It’s fine to turn its power off, especially if your office is going to be empty for long periods. If your unit has a low wattage crankcase heater that keeps its compressor warm, that’s good since a cold compressor usually gets damaged at startup. Once you turn off your air conditioner, make sure that you’ve turned it on for at least 12 hours before use.

How often should I clean my commercial air conditioning unit?

When its filter light flashes, you know it’s time to clean it. Sometimes, however, it still depends on the environment or air purity. In a normal domestic situation, cleaning your air con once every season is enough. But in a commercial situation, we advise cleaning your HVAC system once a month.

How often should I have my air conditioner serviced?

At least twice a year and potentially more frequently in a dirty / dusty environment – like areas with a lot of people and movement, such as sites near busy roads or other dust sources.

Regular servicing of your air conditioner will reduce energy consumption costs.

It is a condition of most commercial leases that the tenant maintains the air conditioners. In the event there is a failure of the system caused by a lack of maintenance, then the landlord may be entitled to have the tenant pay for the repairs / system replacement.

Why are there hot and cold spots in our office?

There are a number of reasons why you have hot and cold spots in an office environment. Some of the common ones are:

Uneven temperature across a large room – caused by unbalanced air flows

Hot offices and rooms when doors are closed – due to a lack of return air pathway

Hot / cold offices and rooms that have sun exposure – varying heat load caused by thermal radiation requires variable air supply to maintain a constant temperature

All of these problems can be remedied, some of them reasonably cheaply.

Why are there hot and cold spots in our office?

Ensure your system is well maintained and reduce run. Some ways of doing this are:

 - Ensuring your filters are clean and the outdoor unit is clear of air pathway obstructions

 - Reduce heat load coming into your property – by externally shading windows or by shutting curtains / blinds.

 - Set the fan on your systems to “auto” rather than on a fixed speed. The fixed speed setting continually circulates air throughout your property to balance the temperature and help you feel more comfortable. But the “auto” setting is the more inexpensive option because it saves energy—the fan only blows when the A/C is producing cool air.

 - Raise the set temperature. Most people are comfortable in an air conditioned environment set at 25 degrees. As a general rule, each degree increase in set temperature, reduces air conditioner energy consumption by 10%.
