Air ConditioningWhy Is My AC Unit Blowing Warm Air?

May 16, 2018by AndersenEMS

When the weather begins to warm, the last thing you want is to have your AC unit blowing warm air. So why does this happen, and what can you do about it? Andersen Heating & Cooling has the answers.

Thermostat still set to HEAT

The first thing you should check if your AC isn’t working is your thermostat. It’s easier than you might think to forget to switch functions once the seasons change, but often homeowners don’t remember to change the setting from HEAT to COOL! Make sure your thermostat settings are correct this spring.

Thermostat fan set to ON

While you’re at the thermostat, check the fan setting. If the fan is set to ON, it will run continuously and blow warm air when the AC unit is cycled off. Set your fan to AUTO this spring in Charlotte.

AC unit blowing warm air due to clogged air filter

Clogged air filters are your air conditioner’s worst enemy. They can cause higher energy bills, which makes your air conditioner work harder, and even cause a premature system failure. To avoid your AC unit blowing warm air, change your filter at least once a month. This will also help ease your allergy symptoms and lower energy bills.
