AC Not Blowing Cold Air

There may be many reasons why your AC is not blowing cold air. This can range from your thermostat being set incorrectly, to power issues. No matter the cause, Complete Air Mechanical is here to help.

5 Reasons Your AC Is Not Blowing Cold Air

1. Your Thermostat is Set Incorrectly

The first thing you should do is check your thermostat as it may be set incorrectly. Ensure it is set to cool and the temperature is set to your ideal setting. Sometimes thermostats may be set to fan, heat, or another setting that may impact your AC unit not blowing cold air.

After checking your settings, wait for a few minutes for your unit to kick back on to cool your home. If it is still blowing warm air, move on to the next step.

2. Dirty Air Filter

Your air filter will be found in the indoor handle unit. The filter’s job is to filter out any dirt, dust, and other airborne particles that you may have otherwise been exposed to. You may want to clean out or replace this filter to see if this is the culprit of your issue.

Before you remove this filter, make sure your AC unit is off. Once you inspect it and put it back in, go ahead and turn on your air again to see if it is now blowing cold air. If not, please move on to the next step.

3. Evaporator Coil Issues

An evaporator coil’s main function is to absorb the heat from the air. When evaporator coils have issues, it can impact the temperature in your home. This coil is also prone to freezing when the unit gets too low in temperature.

The signs of a frozen evaporator coil include:

  • Your home is hotter than the thermostat is set to
  • Higher than normal utility bills
  • Frost on this inside of your unit

If you think your evaporator coil needs to be troubleshot, please call an HVAC professional.

4. There May be a Power Issue

Your unit may have a power issue that is causing your AC not to blow cold air. This could be due to a tripped breaker or a blown fuse. You could resolve this by resetting your breaker. From there, you will want to turn the AC on again to see if it is still blowing warm air.

5. Leaking or Low Refrigerant

Refrigerant is a chemical staple in your unit. Your unit may need more of this chemical to run how it’s supposed to, or your unit may have a refrigerant leak that needs to be repaired.

If you think your unit may be low on refrigerant, please reach out to an HVAC professional.
