1. What is the reason when the aircond is operating but there isn't any cold air?
The air conditioning system consists of two sectors with different functions. The indoor fancoil and the outdoor condenser. The indoor 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, it may cause by the following factors.
- Air filters dirty
- Object blocking the air inlet/outlet of the indoor/outdoor units.
- Aircond temperature is set too high.
- Windows and doors are opened.
- Airflow direction is not appropriately set.
- Remote control is not in the cooling mode.
- Parts may be faulty.
- Fan motor is clod with dust. Thus, cool air is being blocked, therefore cannot be blown out.
- The air conditioner installed is undersized
- Not enough refrigerant in the air conditioning system.
Please contact a qualified service technician to attend to your air conditioner.
2. Why is the air condition leaking water?
Water from the air condition is discharged out through a drainage pipe that is run from the fan coil unit to the nearest drain. Water will start to leak from the fan coil if :
- The drainage / pan or pipe could have been blocked due to some dirt being accumulated at these area.
- Aircond could be dirty
- Poor gradient of the drainage pipe.
- Installer use smaller pipe size for the drainage pipe
3. Why does water drip from the condenser (Outdoor unit)?
It is normal for water to drip from the condenser as condensation takes places when the warm air surrounds the piping condensate.
4. Why does ice-forms on the copper pipes of the condenser (outdoor) unit?
There are two possibilities. Ice-forming on the discharged pipe (the smaller sized one) is due to insufficient gas in the system. Ice-formation on the suction pipe (the bigger one) could be caused by a dirty fan coil unit or, a dirty filter or, the indoor unit blower is not rotating. A qualified technician should engaged to have the air condioner repair.
5. Why is the air conditioner is not working or when it operating, the MCB trips?
The most common reason is that the electrical power is not supply to the air conditioners. If the air conditioner operate for period of time then only it trips. Then , it could be possible that the MCB is under-sized. Please check the recommended MCB size with our service center for your specific model.
6. Why does the air conditioner produce a foul smell?
This is due to the smell of the room, furniture, or cigarettes being absorbed into the unit and is discharged together with the airflow. Please contact qualified technician to service your air conditioner in the event the air con produce a foul smell.
7. Why is my air conditioner so noisy?
The blower and coil may be dirty. OR, the noise may come from the vibration due to uneven wall surface or the indoor installation panel has'nt been install or attached properly to the wall surface OR, the blower wheel which is attached to the indoor fan motor is unbalance or broken . Sometime the noise is due to a glass partition or a thin plywood partition, or, which the compressor operating noise could have been easily transmitted into the room (Please refer to the installation menu).
8. Why is the fan coil unit still operating when the condenser is not?
When the room temperature has reached its set temperature by the remote controller, the condenser will stop operating. It will resume operation once the room temperature rises.
9. What happen if I do not service my aircon?
The life span of the air conditioner will be shortened, coolness decreases with usage and water leaking problem may occur as a result of a choke drainage system. The inefficient operation will then cause the electricity consumption to increase.
10. Do we need to service the Condensing (outdoors) unit? If, yes, how often?
You need to clean the condensing unit at least once a year to make sure the air circulation of the unit is not blocked. If you didn't service the outdoor condenser, then it can affect the cooling efficiency, shorter compressor life and even increase your electrical bill. Sometimes, it is subjected to environmental condition, which requires a qualified technician to give recommendations.
11. Can we do the general service by ourselves and how often?
Cleaning of fan coil and the cover of the air condition can be done easily but to take out the water tray will be tough for some people. To vacuum the drainage system and to check the refrigeration level cannot be done without proper equipment.
Basically, it is recommended that residential air conditioner is to be service and check every 3 months and every month for commercial air conditioner. The duration of how often to service the air conditioners is varies with the different usage pattern and environmental factors. Please seek the assessment from a qualified technician.
12. Can I do my own maintenance on to my air conditioner chemical flushing?
It is not advisable. Since there is a lot of dismantling to do, it is better to get a professional help. When chemical flushing is not done properly, several problems may occur. The chemical flushing should be carry out by a qualified technician.
13. When does the air conditioner needs Chemical overhaul and chemical cleaning ?
When your air conditioner starts blowing badly smell from the indoor fancoil, you should engaged a qualified technician to do chemical cleaning. The smell comes from the bacteria formed by microbes in the warm dark humid environment in the indoor fancoil unit. Chemical overhaul is need when your air conditioners is badly clogged / choked whereby the general servicing can not improve the condition. In an overhaul, the air conditioner is dismantle part by part and chemically wash.
14. Why must your company dismantle the fan coil unit for chemical service instead of
inserting a water tray to wash away the chemical?
By dismantling the fan coil unit, we can clean the air conditioner's individual components thoroughly with the alkaline-based chemical, without leaving behind chemical residue which may lead to the corrosion of the fan coil.
15. What should be done, if there is a refrigerant leakage problem?
If you air conditioner system has a refrigerant leakage problem, simply adding of refrigerant (R22 / R410A) is not a solution. A qualified technician should be engaged to trace and repair the leakage. Upon completion of the repair , a correct amount of refrigerant should be top up.
