Why is My Air Conditioner Freezing Up in Port St. Lucie, Florida I Need Cool Air

Nothing can be more frustrating and exhausting than having an air conditioner freeze up on a hot day. As luck would have it, AC unit freeze-ups typically happen when you need cool air the most. 

This can heat you up in more ways than one. You’ll end up asking yourself, “why is my air conditioner freezing up?”, which is probably what brought you here. Truth be told, frozen air conditioning units are a common problem that many people face. So, you’re not alone.

What Causes AC Units to Freeze Up?

While there are several reasons why your AC unit may freeze up, some solutions are as simple as adjusting the thermostat. Other issues require a professional’s touch with significant HVAC expertise. Some of the most common reasons for AC units freezing include:

  • Refrigerant Line Restriction
  • Filters Are Blocked or Clogged
  • Fans Stop Moving
  • Refrigerant Leaking From The Unit

Any of these issues can cause the refrigerant inside your unit to expand and become too cold, causing your air conditioner to freeze up. The first thing you should do when dealing with an AC unit freeze-up is check the temperature and the unit itself. If you step outside and feel a slight chill in the air, it may be too cold for your AC unit. Experts recommend that you don’t run your AC unit if it’s below 62 degrees Fahrenheit outside.

Check around the unit and look for things that may be blocking airflow such as trash, uncut grass, weeds, etc. Sometimes, fixing a freeze-up is as simple as clearing the area around the unit. If your unit is clear and still freezing up, double-check the hoses aren’t kinked and the fans are running. You’ll be able to hear the fans when they are operating properly without having to open up the unit, which makes it an easy assessment you can do yourself.

After checking the area around the unit and making sure the fans are running, double-check for leaks. If you find any leaks coming from underneath your unit, call an HVAC expert to check on the refrigerant levels and make sure that all the lines and connections are fit and secure.
