Everybody living in Greensboro, NC, knows how the temperature is during summer. While braving the most humid and sweltering days of the year, the last thing you need is to get warm air from your AC unit rather than the cool wind that you gravely want. In fact, this is when we count on our air conditioners the most. 

To avoid this inconvenience, it is vital to know the usual causes of air conditioner problems. In this blog, we will look at the most common causes of this air conditioning problem.

4 Reasons Why Your AC Could Be Blowing Warm Air

There are many causes for an AC unit blowing warm air; some are silly, others are much more serious. Let’s review them:

Wrong Thermostat Settings

Let’s start with the basics; it may sound obvious, but always be sure to double-check that it is set to “auto” and not “on”. The issue of hot air may result from accidentally setting your thermostat to the “heat” setting.

Refrigerant is Low

Refrigerants are responsible for retaining heat from your home’s air. If it leaks, your AC unit will battle to cool your air. You’ll realize you have a refrigerant leak if your indoor and outdoor AC units have ice shaping on them. If the refrigerant is not leaking, then you will have to check the air ducts.

Dirty Air Filter

Dust is responsible for having a dirty filter; the entry of cool and warm air inside the ducts is obstructed. This will lead to the evaporator coils freezing, making your AC unit blow warm air.

Evaporator Coil is Dirty

When the evaporator coil gets blocked with dust and debris, there may not be enough free airflow to permit the proper cooling operation. 

Electric Diagnosis

A loss of power could create problems within the vent. The circuit breaker and fuse panel must get verified. However, be careful; if you constantly check the circuit breaker, you may have a severe electrical problem.
