Why Aircon Not Cool?
Clogged air filter
If the air conditioner does not cool, the air filter might be clogged. In such case, air cannot flow through properly which greatly reduces the cooling capacity of the air conditioner. Either clean the air filter or replace it as needed.
If the air conditioner is not cold enough the condenser coils may be dirty and loaded with debris. In an AC, the condenser is like a radiator that dissipates heat (which was removed from the air). The condenser coil must be clean to dissipate heat outside. As the coils get dirtier the air conditioner becomes less efficient, which makes it work harder to cool the room. If the coils are dirty enough, the unit will never be cold enough and will not be able to cool the room.
The coolant circulates through the evaporator coils and cools the air flowing over it and eventually sends cool air into the room. So when the level of this coolant becomes insufficient, the AC fails to cool. At this stage call a PRO for coolant top up and refill.
A compressor is the heart of an air conditioning unit which is responsible for cooling your room. If the air conditioner does not cool, the compressor might be defective. The compressor is a motor which compresses the refrigerant or coolant and circulates the refrigerant through the evaporator and condenser coils. If the compressor goes bad the cooling cycle does not start and the AC fails to cool.
A thermostat is a sensor that senses the room temperature and hints the compressor to start or stop the cooling cycle. If the thermostat is defective the air conditioner does not cool or may cool continuously.
The other possible technical reasons behind AC not cooling can be a faulty run capacitor of the compressor, defective control board, bad thermistor, choked capillary, faulty motor etc.
High atmospheric temperature
An AC has an optimum operating temperature (surrounding temperature) at which it can work most effectively. If the temperature shoots up beyond the optimum temperature limit, the efficiency of the air conditioner goes down. Sometime it is so hot outside that a stage is reached where the compressor stops working completely.
