6 Reasons Your AC Is Not Cooling and How To Fix It

It can be rather inconvenient if your air conditioning unit produces hot air instead of cooling your house on a humid day. There are various reasons why your air conditioner isn’t cooling, both technical and non-technical, and this problem can put you in trouble, especially during the hot summer months.

Let’s look at six reasons why your air conditioner isn’t cooling and figure out how to fix the issue:

A Clogged Air Filter

If the air conditioner filter is dirty or clogged with dust and dirt, it can cause various problems. The most typical cause of your split and window air conditioners not cooling is a dirty air filter, which can interfere with the thermostat’s regular operation. The cold and hot air movement inside the ducts is blocked by dirt in the AC filter. It can also cause the evaporator coil to freeze, preventing cold air from leaving the outlet. It’s an excellent option to get the AC filter checked by the experts performing HVAC and air conditioning service in Wesley Chapel, FL, and replace it if it’s clogged.

A Malfunctioning or a Broken Thermostat

If your split or window air conditioner isn’t cooling, examine the thermostat’s functioning. If your air conditioner blows cold air first, then hot air, it may be a problem with your thermostat. Your thermostat controls your air conditioning system, so if it isn’t working correctly, it can cause issues.

Change the thermostat settings to auto mode if you are in this situation. As a result, the fan only turns on when the air cools down. If your thermostat’s screen is blank, consider replacing the battery. Also, ensure the AC unit is turned on if your thermostat is not connecting with your air conditioning system.

The AC Condenser is Blocked

Because a compressor handles refrigerant flow between the evaporator and the condenser, a damaged condenser cannot cool the air properly. If the condenser on your AC unit is blocked by leaves, bushes, trees, or other objects, it won’t be able to release as much heat to the surrounding area.

When the heat has nowhere to go, it builds up in the condenser unit, raising the condensing temperature and making the system inefficient to run.

Motor Failure of the Fan

The outdoor unit will be unable to dissipate heat if the fan motor is broken or malfunctioning, interfering with the cooling capability of an air conditioning unit. It is preferable to have this damaged motor problem addressed by a professional, so contact AC repair in Wesley Chapel for better assistance.

Clogged Evaporator Coil

The surface and fins of your evaporator coil are used to chill the air in your air conditioner. Dirt produces an insulating layer on the coil, making it more challenging to cool the air to the required temperature. The cooling effectiveness of your evaporator coil will be reduced if it is covered in dirt or filth.

To clean a dirty evaporator coil, combine warm water and a mild detergent in a spray bottle. Spray solution and wait for a few minutes to soak in before cleaning the dirt.

Lower Refrigerant Level

If your air conditioner isn’t cooling, the refrigerant may be leaking. Refrigerant is a critical fluid that absorbs heat from the surrounding air, and its absence or inadequacy causes your air conditioner to chill. It isn’t possible. To avoid this issue, get your air conditioner serviced regularly. 

They can identify and resolve signs such as hissing or bubbling sounds and snow accumulation on the external unit.


It is strongly recommended that you get it serviced and maintained by a professional to ensure that your air conditioning unit is constantly running correctly.
