My Air Conditioner is Not Blowing Cold Air

There are many reasons why the air conditioner is not blowing cold air. Here are the top 4 reasons why your air conditioner is not blowing cold air:

  • The air filter is blocking airflow.
  • The refrigerant pressure is too low.
  • The circuit breaker tripped.
  • The air ducts have leaks.

Preventative care like air conditioner maintenance is best to avoid why your air conditioner is not blowing cold air. However, having your HVAC contractor service your air conditioner at the first sign of trouble prevents more serious issues.

Air Conditioner Not Is Blowing Cold Air Because of the Air Filter

The air filter in the central air system works to strain particles from the indoor air supply. When an air filter fills to capacity, less air passes through the system altogether.

Whenever this happens, the amount of air the central air system has to condition diminishes. While the system may be working just fine, it feels like your air conditioner is not blowing cold air because so little air makes it back into the house.

Homeowners who have not checked on their air filters in some time should do so. They may discover it to be the cause of the problem.

Air Conditioner Not Is Blowing Cold Air Because of the Refrigerant Pressure

Evaporator coils and refrigerant issues also result in problematic air conditioning.

Refrigerant plays a key role in air conditioning. During the cooling process, refrigerant is compressed, dropping it to a very low temperature. Then, through tubes, it fills the evaporator coils. The coils cool as well and as warm air passes over them, a heat transfer takes place.

When refrigerant fails to compress under pressure, the temperature also fails to drop low enough to cool air. Consequently, while the air conditioning system itself works, air never feels cold enough.

It may also have to do with the amount of refrigerant available. Because refrigerant is in a closed system, it never “runs out,” but it can leak. Inadequate refrigerant levels also results an air conditioner not blowing cold air.

Air Conditioner Not Is Blowing Cold Air Because of the Circuit Breaker

Air conditioner units that have not received maintenance are guilty of tripping circuit breakers.

When air conditioners operate without maintenance, they require more power than usual. Because of this, circuit breakers trip and shut down the air conditioning process, leading to the air conditioner not blowing cold air.

Homeowners who constantly find their circuit breaker tripped should call for air conditioning maintenance. Maintenance solves this problem by cleaning the system of buildup and making the necessary technical adjustments.

Air Conditioner Is Not Blowing Cold Air Because of the Air Ducts

Air Duct With A Hole

The duct system in the attic is used to transport cleaned and conditioned air back into the home. When the ducts experience tears and holes, it results in the conditioner not blowing cold air.

This is because the attic environment differs greatly from the home environment. Attic temperatures easily soar past 100 degrees and the air does not receive the same type of filtration as home air. Consequently, when there are tears, cleaned air escapes into the attic. Meanwhile, dirty attic air enters the ducts and finally, the house. When this happens, it feels that while the central air runs, air doesn’t seem cooler.

The air ducts deteriorate with age and use. In addition, construction mistakes, earthquakes, rodents and accidents can also puncture the ducts.

Homeowners who find a fall in indoor air quality as well as air conditioning temperature may suspect air ducts to be the problem. Have your air ducts inspected by your HVAC technician. Repairs to the air ducts will certainly solve this issue of the air conditioner not blowing cold air.
