During the summer, many homeowners rely on their A/C units more frequently to stay comfortable. There are sometimes issues that cause systems to malfunction when people need them the most. While air conditioning repair addresses these problems, there are minor issues that homeowners may be able to correct themselves.

Why Is My A/C Not Cooling My Home?

1. Clogged Filters

The air filters in your air conditioner catch contaminants, including pollen and dust. When the filters become clogged, accumulated particles block airflow. The grime may also settle on the evaporator coils that transport the refrigerant your A/C needs, compromising cooling.

Change out the air filters to correct this issue. To prevent future trouble, switch the filters every three months. If you have pets, change it every month.

2. Thermostat Issues

If your HVAC unit has cooling and heating capabilities, accidentally setting the unit to the heating mode produces hot air. Malfunctions can also occur when the thermostat needs new batteries, so try switching them.

The setting may also be too high. In the summer, lower the temperature to 78 degrees while you’re at home. Switching to a smart thermostat allows you to monitor usage and make changes to the setting remotely. 

3. Blocked Vents

HVAC units draw in and push out air through vents. Vents often include mechanisms that close, stopping airflow. When these systems are obstructed, the compressors that control refrigerant can freeze, resulting in malfunctions.

Check the vents throughout your home and open any closed ones. If the vents are obstructed by furniture, move the items aside. You may need HVAC repairs for the compressor if the system still doesn’t produce cool air.
