Are you wondering what to do when your AC unit freezes up? One of the most common problems surrounding malfunctioning air conditioning is a frozen AC unit.

You’ll know if this is the case because you’ll see ice on the indoor or outdoor unit.

If this is the case in your home, you’re currently experiencing a very heated environment but don’t worry; here’s a simple guide on how to cool things down.

What To Do When Your Ac Unit Freezes Up

The biggest (mostly main) reason for a frozen AC unit revolves around the restriction of airflow. The following things are what can be checked to try and remedy that problem.

  • Check The Filter

This is usually the number one cause of a frozen air filter. In order to check your air filter, find your return vent, unscrew the cover and check the filter.

If it’s dirty then simply replace it with another filter bought at your local hardware store (without bothering with the remaining steps).

  • Check The Duct Work

See if there are any restrictions within the ducts due to collapsed ductwork, but be careful (most certainly an unsafe environment for your fingers). Your ducts may even be dirty enough to restrict airflow (although this is rare).

  • Try Thawing It Out

In order to thaw your AC, turn your thermostat from cool to off and your fan on. This will really make things hot in your home so feel free to go out from dinner or see a movie.

After this is done, find your air handler and frozen coil—check your condensation panel—you want to make sure it is draining properly. If it isn’t, you could end up with a lot of water damage. Regardless, drop some condensate pan-cleaning tablets into the pan (to prevent odors and build).

If water has built up, however, don’t do the next step.

  • Start It Back Up

If you’ve properly allowed your unit to thaw and everything appears right as rain, switch your thermostat back to cool. If your AC then blows air that is cooler than room temperature then you are good to go.

If none of the above things helped, then you might have a more serious problem such as a weak/bad blower or A refrigerant leak. in this case, you might have to buy a new AC unit.

If you haven’t even gotten to this point or you don’t feel confident beyond checking the filter…
