Answers |
| Question : 1 |
Why is my air-con unit leaking? |
| Answer |
A normal air conditioner will have water condensate in the indoor fan coil and discharge through a draining pipe to the nearest drain.
The drainage pipe could be choked with dirty particles so the water cannot be drained out, causing the leakage from the fan coil unit.  |
| Question : 2 |
Why is my air-con not cold? |
| Answer |
The air conditioning system basically comprises of 2 sections. The indoor fan coil and the outdoor condenser. The indoor fan coil simply acts as a blower to dissipate the cooling generated by the outdoor condenser. If there is no cool air blowing out from the indoor fan coil, the outdoor condenser might not be working. A qualified technician is needed to troubleshoot on the outdoor condenser. |
| |
Some of other reasons for your reference :- |
| |
- The blower and air filter is dirty and clogged with dust.
- The thermostat is set too high.
- The unit is undersize.
- The orientation of the room (eg. facing direct sunlight).
- The refrigerant gas needs to be topped up.
|
| Question : 3 |
Why is the air-con noisy? |
| Answer |
Noise is normally generated from |
| |
- Vibration noise resulted from dirty indoor fan coil/ outdoor condenser
- Noisy draft resulted from dirty indoor fan coil
- Loose mounting of component in the air conditioning system.
- Faulty parts in the air conditioning system
|
| Question : 4 |
Why is the air-con smelly? |
| Answer |
The smell comes from bacteria formed by microbes in the warm dark humid environment in the indoor fan coil unit. Sometimes when the smell is very bad you may need a more intensive chemical treatment to rectify this problem. |
| Question : 5 |
Why does the air-con needs chemical overhaul / chemical cleaning? |
| Answer |
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. |
| Question : 6 |
Why must the fan coil unit be dismantle for chemical overhaul instead of inserting a water tray to wash away the chemical? |
| Answer |
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 lead to the corrosion of the fan coil. |
| Question : 7 |
What will happen if I do not service my air-con unit? |
| Answer |
The aircon unit will gradually be unable to produce cold air and water leakage may occur. |
| Question : 8 |
How frequent should I service my air-con unit? |
| Answer |
a. For residential units, it is advisable to service your aircon every 2 months.
b. For office and commercial units, it should be serviced every month. |
| Question : 9 |
Can I service the air-con unit myself? |
| Answer |
You can clean the fan coil cover and wash the air filters by yourself. However, it is advisable to engage qualified service technicians as they have the proper tools and equipment to service the aircon units, check the safety circuits, refrigerant pressure and also vacuum the drainage pipe. |
| Question : 10 |
Why is it necessary to dismantle the fan coil unit for chemical wash? |
| Answer |
The dirt at the cooling coil can be washed and cleaned thoroughly. |
| Question : 11 |

Workmanship and inferior materials.
- Always check the types of guarantees that the contractors offer.
- Making sure that the contractors have registered offices is a crucial part for accountability.
|
| Question : 13 |
Why is the room not cold enough even after the air-con been running for few
hours? |
| Answer |
- There are a number of causes to this air conditioner not cold situation.
- The indoor fan coil is dirty resulting in weak dissipation of cool air.
- The outdoor condenser is dirty resulting in overheating of compressor.
- There may not be enough refrigerant in the air conditioning system
- There might be some problem with the air conditioning system resulting in non-continuous operation of the system.
|
| Question : 14 |
Why is the air-con not working? |
| Answer |

| Answer |
If your air conditioning system has a refrigerant leakage problem, simply adding of refrigerant (R22 / R410) is not a solution. A trained technician should perform test to trace and repair the leakage. Upon completion of leakage repair, a correct amount of refrigerant should be top up. |
| Question : 20 |
What is the advantage of Air Purifying Filter and how often do we have to replace it? |
| Answer |
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. It's 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. |
| Question : 21 |
Do we need to service the Condenser (outdoors) ? If, yes, how often? |
| Answer |
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. |
| Question : 22 |
Why does ice-forms on the copper pipes of the condenser (outdoor) ? |
| Answer |
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 fan coil unit or, a dirty filter or, the indoor unit blower is not rotating. |
| Question : 23 |
Why is the air con switches OFF by itself and the air-con indicator light is blinking /
flashing |
| Answer |
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 an electrical power reset to get the Air-Con temporary working. Continue operation might further damage the air conditioning system.
|
| Question : 24 |
Why is the air con switches ON and OFF by itself ? |
| Answer |
There is a fault with the indoor electronic circuit board. The circuit board controls the operation of the indoor fan coil and a damage causes it to lose its operational control. A repair or replacement of the circuit board is necessary. |
| Question : 25 |
Why is the air conditioner cannot be switch ON using the remote control ? |
| Answer |
The fault might lies in the remote controller or the indoor printed circuit board. Try the remote controller on other fan coil 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. |
| Question : 26 |
What should I consider when choosing an air conditioner for my premise? |
| Answer |
The following are some factors you should consider when choosing an air conditioning system. |
| |
- Determine the size of the area for which the air conditioner is required to cool.
- Determine the cooling capacity required (refer to question 2 under this section).
- Determine the brands and types of air condition you prefer.
- a)Workout and compare your budget.
