What to do when your air conditioner freezes

May, 6th, 2013

As we get closer to summer and temperatures start to rise, we always see an increase in calls about frozen air conditioning systems. The biggest question is how do you fix this problem? However, the first thing you need to know is why your air conditioner stopped working in the first place.

There are two primary reasons that cause an air conditioner to freeze up. They are:

  • air conditioner tune-upLow refrigerant (Freon) – You can lose refrigerant slowly over time or you could also lose it due to a leak somewhere within the system. An Bi-Annual HVAC maintenance check will help prevent this and keep your home cool during the hot summer months.
  • Restricted air flow – Your AC unit needs consistent air flow in order to work properly. Restricted air flow generally occurs because of dirty or blocked air filters. In order to keep this from happening, you should change the filter once every three months during the months of use.

Now that you know what causes an AC unit to freeze, here are some steps to take once your air conditioner freezes:

  1. Turn it off – As soon as you realize that your air conditioner has frozen, turn it off so that it can defrost. Leaving it running while it is frozen could cause more serious issues.
  2. Check the air filter – Once it is completely thawed, check the air filter to see if it is dirty or completely blocked. If the filter is a replaceable one, simply replace it. If it is one that can be cleaned, be sure to clean it thoroughly and let it dry before putting it back into the air conditioner unit.
  3. Check the refrigerant – There must be enough refrigerant or Freon in the unit to allow the air conditioner to run smoothly. If there is not enough Freon or there is a leak, you will need to call a professional, licensed HVAC contractor.
