How Often Should You Service Your Air Conditioning Unit?

Regular air conditioning servicing helps keep your system running efficiently, reduces the risk of unexpected breakdowns and maintains a comfortable indoor environment.

But how often should you book a service? The answer depends on how frequently you use your unit, the environment it operates in and the type of system you have. Here's what you need to know.

How Often Should Air Conditioning Be Serviced?

As a general recommendation, air conditioning units should be professionally serviced once or twice a year. However, some systems may need more frequent maintenance depending on their workload.

For example:

Domestic air conditioning: Units used mainly during warmer weather may need less frequent attention than those used for both heating and cooling throughout the year.
Commercial air conditioning: Systems in offices, shops and other business premises often operate for longer periods, making regular servicing particularly important.
High-use environments: Units exposed to dust, grease or other contaminants may need more frequent cleaning and maintenance.

At STR, we recommend servicing your domestic air conditioning unit once a year and your commercial or high-use system twice a year. Following the manufacturer's guidance will also help you determine the most suitable servicing schedule.

What Are the Signs Your Air Conditioning Needs Servicing?

Even with regular maintenance, it's worth knowing when your system may need attention. Look out for the following signs:

Reduced cooling or heating: Your unit struggles to maintain the desired temperature.
Unusual noises: Rattling, buzzing or other unfamiliar sounds could indicate a fault.
Unpleasant smells: Persistent odours may point to dirt or moisture within the system.
Water leaks: Water around the indoor unit could indicate a drainage problem.
Rising energy bills: A less efficient system may use more energy to achieve the same results.

If you notice any of these issues, arrange a professional inspection rather than waiting for your next scheduled service.

What Does an Air Conditioning Service Include?

A professional service involves checking the system's condition and making sure its key components are working as they should.

These checks help identify potential issues before they develop into more serious faults. You should also follow the manufacturer's instructions for routine filter cleaning between professional services.

Why Is Regular Air Conditioning Maintenance Important?

Servicing your air conditioning system offers several benefits beyond keeping it clean.

‍Improved energy efficiency: Clean filters and properly maintained components help your system operate efficiently, potentially reducing energy consumption.‍
Fewer unexpected breakdowns: Routine checks can identify worn or faulty components before they cause a system failure.‍
Longer system lifespan: Looking after your equipment can reduce unnecessary strain on its components and help extend its working life.‍
Reliable performance: Regular maintenance helps ensure your air conditioning is ready when you need it, whether you're cooling your home during summer or heating a workspace in winter.
