When you have a frozen AC line, the unit will not be able to efficiently cool your home. This can be a very uncomfortable experience for someone that just came home on a hot summer evening.

What causes an air conditioner to freeze up?

A frozen AC line can be caused by a number of underlying problems including a blocked air filter and low refrigerant charge. When the amount of refrigerant in the AC system is too low or too high, the pressure will drop, causing temperatures to fall below freezing. Water can then condense around the line and coils and freeze the AC unit.

What to do when your AC line freezes up

Whatever the cause of the freeze, there are a few things you can do to get your air conditioning unit working again. Here are some tips on how to unfreeze the AC line:

  • Check the Air Filter

This is probably the best thing to check first to unfreeze the AC line. Find your return vent, unscrew the cover, and check your air filter. If you have a clogged filter, clean it or replace it with a new one. This is an easy procedure you can perform on your own.

  • Thaw Your Frozen AC Line

It is simple to thaw your unit: this will get the AC line and other parts to un-freeze and get ready to work properly again. To achieve this, there are two simple things you can do. You should start by switching your thermostat to ‘OFF’. The defrosting process will start immediately.

Next, you have to make sure that your condensate pan is draining properly to eliminate the risk of water damage. You can throw in a few condensate pan cleaning tablets to make your home smell nice afterward. Give your AC unit a few hours to fully defrost and it will be ready for use again.

  • Start Your AC Again

When you are sure that your AC line has been fully defrosted, you can start it up again. All you need to do is switch the thermostat back to COOL and wait for the unit to cool your home.

It is important to note that while the steps above can unfreeze your frozen AC line, it doesn’t solve the problem completely and you still might need to have your air conditioning system professionally assessed to avoid further trouble. We recommend to contact an HVAC professional, especially if your AC unit freezes often. A component might be broken and you might need to get air conditioning repair services.
