Common Reasons Your Oklahoma A/C Is Blowing Hot Air

Common Reasons Your Oklahoma A/C Is Blowing Hot AirWhen your air conditioner stops producing cool air, you need to get the problem solved quickly to avoid any discomfort. Here are some of the most common reasons why your central A/C is blowing hot air, with advice on how to solve the easy fixes and when to call your HVAC pro for help.

Wrong Fan Setting

If your thermostat fan gets switched over to “on” instead of “auto,” the blower fan will stay running after the cooling coil cycles off and push out warm air at the registers. Switching the thermostat back on the “auto” setting should put the different components back in sync.

Tripped Circuit Breaker

The indoor and outdoor A/C units are controlled by separate breakers in your home’s electrical panel. If just the outdoor unit’s breaker trips, the blower will circulate warm air. You can try resetting the breaker, but if it immediately trips again, leave it alone and call an experienced HVAC technician.

Blocked Air Filter

If you’ve neglected to replace the air filter lately and it’s clogged with debris, the lack of adequate airflow may be suffocating the system and reducing cool air output. To solve this issue, inspect the air filter once a month and change it when there’s any visible accumulation of dirt.

Low Refrigerant

If the refrigerant level has dropped, your air conditioner’s cooling capabilities can decline. A low refrigerant level usually indicates a leak somewhere in the system that your HVAC contractor needs to locate and fix to restore the flow of cool air at the registers.

Dirty Condenser Coil

It’s easy for dust to build up on the condenser coil and hinder proper heat transfer. Tall grass around the condenser unit can also impair vital airflow. Both of these issues can reduce cool air output, so clear the area around the unit and hose off the coil to get rid of dust and dirt. If there’s no noticeable improvement, the condenser may need a professional cleaning.
