Orlando AC Facts: Should My AC be Frozen Over?

It’s hot out, so you have your AC running constantly trying to keep the hot air out and the cool air in. Sometimes, your unit can freeze over, and you wonder, “Is this normal?” Here are our Orlando AC facts that you should know about.


It can be really annoying trying to figure out what’s going on with your AC unit. How can it be frozen over if it’s just so hot out? Here are our Orlando AC facts that can help you understand what’s going on.

How You Can Tell Your AC Unit Is Frozen

There are a number of ways that you can tell that your AC unit is frozen over. Here are just a few ideas:

  • AC unit is not working
  • AC unit is not cooling some rooms
  • Air coming out of vents is warm, not cool

What You Can Do

Check the access panel to the evaporator. Make sure you shut off the unit first. If the evaporator is frozen over, then there is the issue. This usually occurs when the unit is running too cold for too long. The refrigerant in the system most likely fell below 32 degrees and thus froze over.

Defrost Your Unit

This is where it gets complicated; you will need to defrost your unit. One of the best solutions is to shut off the power completely to your unit and let it defrost for about 24 hours. This, in the dead heat of the summer, may not be something that you really want to wait on.

You can also try and speed up the process with a hairdryer, but we don’t recommend this because you could crack the coils. It’s like powering hot water on an iced-over car window. You can damage it.

How to Prevent

The best thing you can do is always get your AC unit checked by an HVAC professional every 6 months. Regular inspections can prevent issues like this from ever occurring.
