AC System Blowing Warm Air: Possible Causes & Solutions

There are several reasons why your air conditioner may begin to blow warm air. Below are just a few key areas to inspect and some quick troubleshooting tips you can try to regain full functionality before calling in an expert:

1. Check Your Thermostat for an Error

One of the first things you should do when your AC system is blowing warm air is check your thermostat for errors. A misconfigured thermostat can mistakenly signal your air conditioner to blow warm air instead of cool air. Ensure that your thermostat is set to the cooling mode and that the desired temperature is lower than the current room temperature.

2. Check for a Frozen Evaporator Coil

A frozen evaporator coil is another common culprit behind warm air blowing from your AC. When coils are frozen over, it can restrict the airflow and prevent the system from cooling effectively. Check the indoor unit of your AC system for signs of ice or frost buildup. If you notice any, turn off the air conditioner and let the ice thaw before using it again.

3. Check for a Refrigerant Leak

Low refrigerant levels due to a leak can also lead to warm air blowing from your AC system. Refrigerant is responsible for absorbing heat from the air, so the cooling process is compromised when the levels are low. If you suspect a refrigerant leak, it’s essential to contact a professional HVAC contractor to locate and repair the issue and then recharge the refrigerant to the proper levels.
