Is Your Air Conditioner Blowing Hot Air? Some Common Remedies

In southeast Michigan, the last thing you need is an A/C that’s blowing hot air during the hot summer months. If you have noticed your home does not feel comfortable only to discover hot air coming out of the vents, there are a few fixes you can try yourself. If they fail to work, it is time to call in one of our expert HVAC technicians to repair your central air conditioning.

Replace the air filter. If you have not changed the air filter in a while, it could be completely clogged with dirt, dust, pet dander, and other debris. This will severely restrict airflow, which could impact your system’s ability to cool properly. To ensure this does not happen again, be sure to change the air filter frequently. It is best to check the filter monthly.

Check the thermostat. We all make mistakes, and the thermostat could have been switched over to heating mode inadvertently. Additionally, this can occur if the thermostat has been switched to “on” instead of “auto,” which causes the fan to run continuously.

Could a refrigerant leak be the culprit? When the refrigerant in your air conditioning system drops below a certain level, it usually indicates a leak. Our HVAC technicians can diagnose the issue and repair the leak promptly if this is the case, as trying to repair it yourself could result in damage to your equipment.

Check to ensure the outdoor unit is receiving power. A tripped breaker in the main electrical panel can result in the indoor blower fan operating, while the outdoor unit does not receive power. Your system cannot pump cold air if the breaker is tripped. If this is the case, reset the breaker. This may solve the issue, however, if the breaker quickly trips again or repeatedly, call the professionals and leave the breaker off.

The outdoor condenser coil may need cleaning. When the condenser coil located outdoors accumulates dirt/debris or becomes obstructed by tall grass, it can cause your A/C system to lose cooling capacity. Hose off the coil gently, and remove any obstructions around the unit. If this does not work, have the condenser coil cleaned by professionals.
