No matter how diligent you are about replacing your air conditioner filters and having regular air conditioner maintenance, there is still a chance that your air conditioner could freeze up during the summer. Before we get into how to fix the problem of your air conditioner freezing up, let’s take a look at what could cause your air conditioner to freeze up in the first place.

What makes an air conditioner freeze?

There are three main things that can cause an air conditioner to freeze up:

Lack of air flow – this is the most common reason that many air conditioners freeze up. Dirty air filters or undersized ducts can limit airflow, causing the temperature of the cooling coil to drop to below freezing. Usually, changing the filters is enough to fix the problem. However, if your air conditioner is freezing up due to undersized ducts, the problem is a result of weakened airflow causing humidity in the air to build up and freeze on the coil.

Refrigerant leaks – the amount of refrigerant in your air conditioner has to be carefully controlled if you want to keep your air conditioner running effectively. Too much, or too little, refrigerant in your system could cause your air conditioner to freeze (or not provide enough cooling).

Outdoor temperature – when it gets especially cold at night, there is a chance that your air conditioner could freeze up. Air conditioners don’t do well when temperatures are below 60 F – if temperatures dip this low, turn off the AC and open the windows to save some energy!

What To Do if Your Air Conditioner Freezes

The steps you should take to fix your air conditioner if it freezes depend on the reason why it froze.

If your air conditioner is frozen, turn it off immediately and let it defrost – this will prevent any serious damage to the system. Next, check all the air filters in your home to see if they are dirty or blocked. If they are, clean or replace them. Check back in 24 hours – if there is no more ice on your compressor, changing the filters solved the problem.

If it’s a lack of refrigerant that has caused your air conditioner to freeze, it’s best to talk to an HVAC contractor. They will know the exact level to set your refrigerant at to ensure optimal air conditioner operation. In addition, if your air conditioner is freezing due to a refrigerant leak, they will be able to fix the problem. There’s also the chance that your defrost timer is on the fritz.
