Why is the aircon switches ON and OFF by itself ? 21. Why is the air conditioner cannot be switch ON using the remote control ? 1. Why is the aircon operating but there isn't any cold air (aircon not cold)? 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. 2. Why is the aircon leaking water? A normal air conditioner will have water condensate in the indoor fancoil and discharge through a draining pipe to the nearest drain. Water will start to leak when the drainage piping is clogged / choked. 3. Why is the room not cold enough even after the aircon been running for few hours? 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. 4. Why is the aircon not working? One common reason is that the electrical power is not supply 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. 5. What is the advantage of regular aircon service? 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 prolong. 6. How often should I have the air con service? In general, 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 varies with different usage pattern and other environmental factors. Please seek the assessment of a qualified technician. 7. Can I do my own air-con maintenance? 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. 8. Why is the air con noisy? Noise is normally generated from a. Vibration noise resulted from dirty indoor fancoil/ outdoor condenser. b. Noisy draft resulted from dirty indoor fancoil. c. Loose mounting of component in the air conditioning system. d. Faulty parts in the air conditioning system. 9. Why is the air con smelly? 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. 10. Why does the air con needs chemical overhaul / chemical cleaning? 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. 11. Why must the fancoil unit be dismantle for chemical overhaul instead of inserting a water tray to wash away the chemical? 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 add to the corrosion of the fan coil. 12. What types of air-con do your company service?

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. 16. What is the advantage of Air Purifying Filter and how often do we have to replace it? 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. 17. Do we need to service the Condenser (outdoors) ? If, yes, how often? 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. 18. Why does ice-forms on the copper pipes of the condenser (outdoor) ? 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. 19. Why is the air con switches OFF by itself and the aircon indicator light is blinking / flashing ? 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. 20. Why is the air con switches ON and OFF by itself ? There is a fault with the indoor electronic circuit board. The circuit board control the operation of the indoor fancoil and a damage cause it to lost its operational control. A repair or replacement of the circuit board is necessary. 21. Why is the air conditioner cannot be switch ON using the remote control ? 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. |
