Is Your AC Not Cooling? Find Out the Reasons and How to Fix It

Are you wondering why your air conditioning unit is blowing out hot air instead of cooling your home? This problem can be caused by various factors, causing your air conditioning system to not run in its proper state. Read on to learn the top reasons why your AC is not cooling your room and the steps to fix it. 

Dirty air filter

This is the most common reason why your AC is not cooling. If the filter is unclean or clogged by dust and dirt, it could cause various problems. It could interfere with the proper working of the thermostat and dirt in the AC filters can block the passage of cool and warm air inside the ducts. It could also make the evaporator coil freeze, thus blocking the passage of cool air from the outlet. Get your filter checked by experienced aircon technicians, such as J&M Costa, to make sure it is not causing blockage and other issues for your AC. 

Incorrect thermostat settings

Always check the settings of your thermostat if your split AC or window AC is not cooling. Turn the thermostat settings to auto mode instead of keeping it always on On mode. This way, the fan works only when the air is being cooled.

Dirty outside unit

Another reason why your AC is blowing hot air is because of poor maintenance of the outside unit. The unclean outside unit can get in the way of your AC system, so it is important that you understand how air conditioning works. Your AC is made up of the evaporator (inside unit) which absorbs heat from the air around you and the condenser (outside unit) which condenses the hot air into cool air. A clogged condenser will not allow proper cooling of the air conditioning system and debris will block even heat transfer.

Clean your condenser regularly to give it ample room to breathe. Remove weeds and dirt that surround it and have it checked by technicians on a regular basis. 

Faulty motor

A broken or faulty fan motor can cause the outdoor unit to be unable to dissipate heat, thus hindering the cooling capacity of your air conditioning unit. If you suspect this is the case, get a reliable aircon technician to fix or replace it. 

Low refrigerant level

The refrigerant is the fluid that absorbs heat from the surrounding air. If there is insufficient refrigerant in your air conditioning unit, your AC will not be able to do its job. It is possible that your refrigerant is leaking. If you hear hissing or bubbling noises and a buildup of ice on the outside unit, then call a professional to get this problem sorted.

Damaged compressor

The compressor manages the flow of refrigerant between the evaporator and condenser, so it is an important part of the AC unit. If the condenser is damaged, the unit cannot cool the air well enough. A damaged compressor needs a replacement so you need to get it checked by a professional. 


What’s Next? 

To keep your AC working properly, it is recommended that you get your air conditioning unit serviced and maintained by professionals regularly. Regular maintenance can help you detect and prevent future costly problems.
