AC is Blowing Warm Air

3 Reasons Your AC is Blowing Warm Air


If your air conditioning unit is blowing warm air, don’t panic! There are a few likely culprits and fixes you can try before calling a pro. Here are the 3 most common reasons your A/C is blowing warm air and how to troubleshoot them.

Wrong thermostat setting

An improper setting on your AC thermostat affects your HVAC system’s ability to regulate temperature and can lead to a variety of problems. Before you turn on your air conditioner this summer, check your thermostat and ensure it is set to “cool”. For better AC performance, consider investing in a smart thermostat.

Clogged air filters

Your AC traps particles in the air as it enters your home through its filters. Without proper maintenance, dust and debris can accumulate on your air filters, restricting airflow. This can cause your air conditioner to blow warm air instead of cold air.

To prevent dirty, clogged air filters, make sure to clean your filters regularly. Experts recommend replacing your air filters with new ones every 30 to 90 days.

Lack of power

Before you panic and call in the professionals to fix your AC for blowing warm air, try to check if you are able to turn on the power to the unit. Most homeowners forget to turn on the power to the outdoor unit and suffer a whole day of no cooling inside their homes. If you have an electrical problem in your home, have your system checked and serviced by a pro.
