Air filter problem
If the aircon does not cool, the air filter might be affected by dust . In such case, air cannot flow through properly which greatly reduces the cooling Level of the air conditioner. Either clean the air filter or replace it as needed. (Note:every 2 month once should clean using normal brushes)
Dirty coils
If the air conditioner is not cold enough the condenser coils may be dirty and loaded with dust. In an Aircon, the condenser is like a radiator that dissipates heat. The condenser coil must be clean to dissipate heat outside. As the coils get dirtier the AC becomes less efficient, If the coils are dirty enough, the unit will never be cold enough and will not be able to cool the room.
Insufficient coolant
The coolant circulates through the evaporator coils and cools the air flowing over it and eventually sends cool air into the room. when the level of the coolant becomes insufficient, the Air conditioner fails to cool. at the stage call to Professional Engineer for coolant top up and refill.
compressor Repair
A compressor is the heart of an air conditioning unit which is responsible for cooling your Home. If the aircon does not cool, the compressor might be in a problem. The compressor is a motor which compresses the coolant and circulates the refrigerant through the evaporator and condenser coils. If the compressor goes bad condition the cooling cycle does not working good and the Aircon fails to cool.it running but not produce
