Why Your AC Might Be Blowing Warm Air — and What Longwood Homeowners Can Do About It

Noticing your home’s AC blowing warm air is more than just a frustrating setback; it could be a sign of many potential issues that can leave you without effective cooling when you need it most. 

With that in mind, here are some of the most common problems that could lead to your AC blowing warm air and the steps you should take to get your unit back in working order:

Refrigerant Issues

Your AC system can’t provide effective cooling without refrigerant, a substance that carries heat out from within your home. Low refrigerant levels (whether from slow or sudden leaks) could be behind your AC’s poor performance. There could also be some problem with the unit’s compressor, as it is essential to drive refrigerant flow and achieve proper cooling.

Restricted Airflow

You might also catch your AC blowing warm air when it has trouble achieving the appropriate level of airflow. In many cases, that is due to a clogged filter. Air filters keep dust out of the system and stop particles from circulating in your home, but they need replacement every few months. You could also have duct issues allowing warm air into the mix.

Thermostat Issues

Thermostats play a key role in regulating temperatures in your home. If yours is broken or improperly calibrated, then it can signal your AC incorrectly, causing the system to blow warm air.

Keep Up With Routine AC Maintenance

The best way to keep your system from blowing warm air is to schedule annual tune-ups before the summer months arrive. The process will ensure that your system is operating properly and can also serve as an opportunity to identify any potential issues.
