4 Steps to Take When Your AC Unit Freezes Up

AC unit Freezing up in Lincoln, NE

Many people in Lincoln rely on their HVAC systems to keep their homes comfortable throughout the year. However, if your AC unit freezes up, it can be challenging to get it working properly again. Here are four things to do when that happens.

1. Turn the Thermostat From Cool to Off

The first thing you should do is turn the thermostat from COOL to OFF. This will help prevent the unit from working harder to try and cool the air, which can cause further damage. Because the refrigerant is much cooler than normal, it might kill the condenser, which should receive it as a superheated gas instead of a cold liquid.

2. Turn the Fan On

You should turn on the fan setting to help prevent the AC unit from freezing up more and will also circulate the air in your home. If you have a lot of ice buildup on your AC unit, you may need to turn the fan setting to the “High” position. This will help thaw the ice and prevent it from building up again.

3. Cleaning and Replacing the Return Air Filters

Cleaning or replacing your return air filters is one of the most important things you can do to keep your AC unit running smoothly. Clogging of the return air filters puts extra strain on the blower and can cause the evaporator coils to freeze up. You should check the return air filters or replace them immediately when the AC unit freezes.

4. Open the Dampers and Supply Vents

When the AC unit freezes, you should open all of the dampers and supply vents of the whole system. This will allow air to circulate and help thaw the ice in the unit.
