Why Isn't My Air Conditioner Blowing Cool Air?

HVAC Repair Technician

When your HVAC system stops blowing cold air, you can troubleshoot for basic heating and air conditioning problems. If you notice your air conditioner is turned on but it is not blowing cold air and it's the middle of a hot summer day, that's a big problem you simply can't deny.

Before you call for professional repair, there are a few basic troubleshooting steps you can take to attempt to deal with the issue on your own. These include:

Get on the A/C Clean Team

Your air conditioner's cycle is controlled by the setting on the thermostat. If your air conditioner is running but no cool air is exiting the vents, the blower may be the problem or the air conditioner may be dirty. Air conditioner units require cleaning every spring. Regular cleaning prevents clogged filters and condensers, which may obstruct cool air from entering your home.

Check the Thermostat

Make sure your thermostat is set for cooling, and the fan is set to "Auto." This will enable the fan to turn on when the cooling cycle turns on. If the fan comes on, but no cold air comes out, then the thermostat is not triggering the cooling cycle properly. The thermostat is either faulty or the wiring has been connected incorrectly.

Clean the Condenser

Another common cause of reduced cooling in home air conditioners is a dirty condenser unit (that's the outside part of your air conditioning system). Buildup of dirt on the condenser coils prevents your AC from properly cooling your air. The condenser coils need cleaning annually to maintain peak efficiency.

When it's Time to Call the Pros

These are just a few easy things you can check yourself to find the source of your air conditioning problem. If you're still having issues, there could be any number of other problems that would require a qualified HVAC professional to help you diagnose and fix these problems.
