Air Conditioning by Treat’s Heating & Cooling

If your air conditioning is turning on but blowing warm air instead of cold; there are a few reasons this could be happening but here are a few things to check before you call Treat’s Heating & Cooling for service.

Check your thermostat setting: If the fan is blowing but the air seems warm or not cool, check the thermostat to see if it is set to “on” or “auto”.  If it is set to “on”, your fan will stay on all the time, even when your air conditioner isn’t cooling the home.  This setting helps circulate air throughout your home, but can lead people to think that their AC is blowing warm air and it’s using much more energy.  Change your thermostat to “auto” if it’s currently set to “on” to avoid this.

Change your air filter: the air filter in your air conditioning system protects your air conditioner by removing large dirt particles and debris from the air.  But if you leave the same filter in there for too long, it gets filled with dirt and restricts the airflow to the air conditioner.

This can cause the condenser unit to freeze up, keeping the AC from cooling your air.

High efficiency air filters are designed to remove tiny airborne particles but they can also restrict airflow to your AC just like a dirt air filter does.  This can cause the condenser to freeze so your AC can’t cool the air properly.

Look at your condenser unit: Another common cause of reduced cooling in home air conditioners is a dirty condenser unit, which is outside.  Buildup of dirt on the condenser coils (tubes that the refrigerant flows through) prevents your AC from properly cooling your air.  The condenser coils need cleaning annually to maintain peak efficiency.

If you have checked all of these things and are still having problems with your air conditioner call Treat’s Heating & Cooling for a service appointment 360.825.0800.
