Three Common Reasons Your AC Might be Blowing Warm Air
Few things are more frustrating on a hot summer day than an air conditioner blowing warm air. Many homeowners depend on the AC to keep cool and comfortable, so discovering that it’s doing the complete opposite is an annoyance.
It’s important to schedule professional air conditioner maintenance to prevent serious AC problems; however, sometimes getting the cool air flowing is an easy DIY fix. We’ve outlined the three most common causes of this frustrating issue.
1. Thermostat Set Incorrectly
The first step in figuring out why your AC is blowing warm air is to simply check the thermostat settings. Because we’re just coming out of heating season, it’s easy to forget to switch your thermostat setting from HEAT to COOL. Also, be sure to switch your fan setting to AUTO so it will only circulate air when the air conditioner is running.
2. Restricted Airflow
Reduced airflow is another problem which can cause your air conditioner to blow warm air. A clogged filter can reduce airflow by preventing air from entering the system. It’s important to check the air filter regularly and change it when needed.
3. Circuit Breaker Issues
Another reason why your AC might be blowing warm air is that the outdoor unit isn’t receiving electricity. HVAC systems require a lot of power to keep running, so it’s possible that it overloaded the circuit or blew a fuse. Check the circuit breaker and fuse box to make sure your outdoor AC unit is getting the electricity it needs to properly operate.
You should always contact a certified HVAC professional immediately if your air conditioner frequently causes a tripped circuit breaker or blown fuse, as this could indicate a more significant problem.
