Frequently Asked Questions

Is Aircon Servicing Important?

Aircon servicing is a necessary part of your aircon maintenance. The benefits of regular maintenance includes:

1) The longevity of your aircon. A well maintain air-conditioning will be able to last longer

2) Clean aircon ensures that your aircon is operating at its optimal level which in turn helps reduce your utility bill.

3) Cleaner air circulation which is important if you have family members with a sensitive nose.

As the cost of air-conditioning rises, it is definitely cheaper to do aircon maintenance than to purchase a new aircon. On top of that, by keeping your aircon clean, you save on your electrical bills while ensuring that the air that is produced is cleaner for you & your family.

As with all equipment, the higher the usage, the more often maintenance is required. Below is rough time frame of usage for your reference.

Regular Usage
If you use daily on an average of 6-8 hours daily, you will require to service your aircon on a more regular.  With higher usage, dust & dirt starts to accumulate and over time may decrease the efficiency of your air-conditioning. For daily usage, we recommend general aircon servicing to be done on your aircon once every 3 months

Occasional Usage
For homeowners that use their aircon less often, you may choose to service your aircon on a longer interval. For such cases, we recommend chemical aircon servicing once every 2 years to ensure the longevity of the aircon

For homeowners who are more hands-on and would like to clean their own aircon, here are some simple steps you can follow for basic maintenance. These involve accessing the fan coil, which is usually as easy as lifting the cover of your unit.

Various air-conditioning models may vary and it is recommended that you do a video search on youtube to understand the method to avoid damaging your air-conditioning.

Step 1:

Gently lift the cover of your aircon and remove the filters

Step 2:

Thoroughly wash your filters with water and dry it before putting the filters back into your aircon

Step 3:

Check for any large particles of dirt that is visible on fan coil and gently use a vaccum to remove it. Do not use excessive force which may damage the fan coil

Step 4:

Place the removed filters(make sure they are dry) back into their orginal position and close the lit of yoir aircon

If your aircon is taking longer than usual to cool the room, blowing warm air, or you notice ice forming on the copper pipes outside, these are common signs that your refrigerant level may be low. The most accurate way to confirm is to have a technician check the gas pressure using a manifold gauge.

It is not recommended. Handling refrigerant requires proper tools, safety equipment and technical knowledge. Using the wrong type of gas or overfilling the system can damage your aircon and void your warranty. It is always safer and more cost effective to engage a certified technician to do the job correctly

The cost depends on the type of refrigerant your aircon uses as well as the type of unit you have. Prices vary accordingly so it is best to contact us directly for an accurate quote. 

Not necessarily. If your aircon is low on gas, it usually means there is a leak somewhere in the system. Topping up the gas without fixing the leak first means the refrigerant will run out again over time. A proper gas top up service should always include a leak check and repair before the refrigerant is refilled. This is what our technicians at CoolAire do on every job.
