AC Not Cooling - 10 Reasons Behind AC Not Cooling Properly |

On the hot summer day, you least want an air conditioner that cannot be cold. There can be several reasons behind the AC not cooling, some of which are technical flaws and some are non-technical.
The most common reasons for AC not cooling are:

 

 

 

 

Dirty or Blocked Evaporator Coil

If the air conditioner is not cold, the condenser coil can be filled with dirt and debris. In an AC, the condenser is like a radiator that destroys the heat (which was removed from the air). The condenser coil should be clean to spread the outside heat. Since the coil contains dirt, the air conditioner is less efficient, which makes it harder to cool the room. If the coils are sufficiently dirty, then the unit will never be cold enough and will not be able to cool the room.

Choked Air Filter with Dust

If the air conditioner is not cold, the air filter may be closed. In such a case, the air can not flow properly, which greatly reduces the cooling capacity of the air conditioner. Either clean the filter or replace it pro re nata.

 

 

 

 



 

 

 

Brocken or Open Thermostat


If your AC not cooling in the house then, the thermostat could be a reason for it. The thermostat is a sensor that feels the temperature of the room and prompts the compressor to start or stop the cooling cycle. If the thermostat is bad then the air conditioner is not cold or can be cold continuously.

 

 

 

 

Insufficient Refrigerant In the Unit – AC Not Cooling


The coolant rotates through the evaporative coil and cools the air flowing on it and finally sends cold air into the room. So when the level of this cooling becomes insufficient, the AC fails to be cold. At this level, call a PRO for coolant top-ups and refill.

  • Creating ice on the chill line and outer unit
  • Noisy
  • The AC can not cool the house especially on hot days, but it is fine in cold days and nights.

 

 

 

 

 

Maybe Yor Compressor is Defective

A compressor is the heart of the AC system, which rotates like blood between the inside and outside the unit. If it is damaged, then AC cannot cool your air. A compressor is working in the air conditioning unit that is responsible for cooling down your room. If the air conditioner is not cold, then the compressor can get worse. A compressor is a motor that compresses the refrigerant or coolant and transmits the refrigerant through the evaporator and condenser coil. If the compressor gets damaged, the cooling cycle does not start and the AC fails to be cold.

 

 

 

A faulty or broken condenser fan

If the unit of the outer side of our ac has lost the fan motor or fan blade then the heating exhaust of our ac will not be available. Due to which our ac room will not be able to cool. Before we changed the motor outside unit, also make sure that there is no fault in motor wiring. Sometimes our motor’s ac stops due to the burning of one of our cages.

 

 

 



 

 

 

Defective Parts In the Unit

Other possible technical reasons behind the non-cooling of AC can be a faulty run capacitor of the compressor, faulty control board, poor thermister, choke capillary, defective motor, etc.

 

 

 

 

High Atmospheric Temperature


An AC has an optimal operating temperature, on which it can work most effectively. If the temperature exceeds the optimum temperature limit, then the efficiency of the air conditioner decreases. Sometimes it is so hot outside that it reaches a stage where compressor stops working completely.

 

 

Underscore AC In The Room

One common mistake that people make is that they buy AC based on their budget and not on the basis of the room requirement. In a large room, a small AC will always be difficult to cool the room in the summit summers. The size of the AC ought to be consistent with the dimensions of the space.

 

 

Defective AC Remote Control

There may also be a situation when a temperature change signal to the remote AC unit fails to send.
