FAQ-Air Conditioning Service

The air conditioning system basically comprises of 2 sections. The indoor fancoil and the outdoor condenser. The indoor fancoil simply act as a blower to dissipate the cooling generated by the outdoor condenser. If there is no cool air blowing out from the indoor fancoil, the outdoor condenser might not be working. A qualified technician is needed to troubleshoot on the outdoor condenser.

A normal air conditioner will have water condensate in the indoor fancoil and discharge through a draining pipe to the nearest drain. The Air Conditioner will start leaking water when the drainage piping is clogged / choked. General aircon servicing normally involves the vacuuming of the drain pipe which may rectify the pipe chokage.

There are a number of causes to this air conditioner not cold situation

Reason 1: The indoor fancoil is dirty resulting in weak dissipation of cool air.
Reason 2: The outdoor condenser is dirty resulting in incapable of producing cooling refrigerant.
Reason 3: There may not be enough refrigerant in the air conditioning system.
Reason 4: There might be some problem with the air conditioning system resulting in non-continuous operation of he system.
Reason 5: The desired operating temperature is set too high.
Reason 6: The air conditioner installed is under-sized.

One common reason is that the electrical power is not being supplied to the air conditioner. Perform an initial check on your electrical panel making sure that the electrical supply to the air conditioner has not trip. Upon confirmation of the availability of electrical supply, a qualified technician should be engaged to have the air conditioner repair.

Regular service of your air conditioning equipments will provide the following benefits:

Benefit 1: The air conditioner will cool better.
Benefit 2: The electrical consumption of the air conditioning equipments will be lower.
Benefit 3: Aircon leaking will be minimize.
Benefit 4: There will be less need for aircon repair.
Benefit 5: The air con equipment lifespan will be prolonged.

In general, it is recommended that residential air conditioners be serviced and checked every 3 months and every month for commercial air conditioner. The duration varies with different usage pattern and other environmental factors. Please seek the assessment of a qualified technician.

The basic maintenance that is recommended is the cleaning of the air filter and outer panel of the air conditioner every 2 weeks. This will helps to improve the air conditioning of the room.

Noise is normally generated from

Vibration noise resulted from dirty indoor fancoil/ outdoor condenser.
Noisy draft resulted from dirty indoor fancoil.
Loose mounting of component in the air conditioning system.
Faulty parts in the air conditioning system.

The smell comes from bacteria formed by microbes in the warm dark humid environment in the indoor fancoil unit. Sometimes when the smell is very bad you may need a more intensive chemical treatment to rectify this problem.

Chemical overhaul/cleaning is a very thorough way of cleaning the air conditioner. When an air conditioner is badly clogged/ choked and a general service can’t improve the condition, an overhaul is necessary. In an overhaul, the air conditioner is dismantle part by part and chemically wash.

By dismantling the fan coil unit, the air conditioning individual components can be washed thoroughly. This will help better clean the unit and also not leaving behind chemical residue that may leas to the corrosion of the fan coil.

Evaluate and advice

When engaging an air conditioning company (air conditioning contractor), you should go for a company that is established and reliable. Find out their profile and experience and their after service warranty.

We also provide 30 days of post service warranty for all jobs rendered.

If your air conditioning system has a refrigerant gas leak problem, simply adding of refrigerant gas (R22 / R410) is not a solution. A trained technician should perform pressure testing to trace and repair the leakage point. Upon completion of leaking repair, a correct amount of refrigerant gas should be top up.

Most new model of air conditioner comes with air purifying filter. Air Purifying Filter can remove smoking odour, human smell, impurities and harmful particles in the air condition space. Its recommended that the purifying filter is replaced every three to six months. Or the color of purifying filter (originally white color) is changed to dark brown or black. Leaving dirty air purifying filter in the air conditioning system will affect its cooling performance.

You need to service the condenser (outdoor air conditioning unit) at least once a year to make sure the air circulation of the unit is not blocked. It can affect the cooling efficiency, a shorter compressor life and higher electrical consumption. Sometimes, it is subjected to environmental condition, which requires a qualified technician to give recommendations.

There are 2 possibilities. Ice-forming on the discharged pipe is due to insufficient gas in the system. Ice-formation on the suction pipe could be caused by a dirty fancoil unit or, a dirty filter or, the indoor unit blower is not rotating.

The blinking / flashing of indicator light indicate that there is a fault with the air conditioning system. Hence the air conditioner switches off by itself. A qualified technician is needed to diagnose and repair the fault. As this is a protective function to prevent the air conditioner from further damage, it is not advisable to do a electrical power reset to get the aircon temporary working. Continue operation might further damage the air conditioning system.

There is a fault with the indoor electronic circuit board. The circuit board controls the operation of the indoor fancoil and damage causes it to lose its operational control. A repair or replacement of the circuit board is necessary.

The fault might lies in the remote controller or the indoor printed circuit board. Try the remote controller on other fancoil and if it work, your remote controller is fine. If the fault lies in the printed circuit board, you need to engage a qualified technician to do repair on the printed circuit board.

When the refrigerant gas in an air conditioning system depletes away and the air conditioner needs to regularly top up refrigerant gas, we can suspect that there is air conditioning refrigerant leaking in the system. Pressure testing work will help to identify which is the leakage area. Normally high pressure is induced into the condenser, fancoil and refrigerant piping to identify where is the leakage. Further repair work will be quoted upon identifying the leakage area.

Note: Pressure testing work is a testing process (not repair work) to identify the leakage area. This work will not be able to rectify the fault but it’s a necessary process to define the scope of repair deriving from the result of the testing work. The leakage area defined herein is an indicative section of the refrigerant system. Our pressure test are unable to pinpoint leakage location.
