What to Do If Your Air Conditioner Freezes

It’s getting warmer in the Baton Rouge area (hooray!), and summer is quickly approaching! With warm weather on the way, the last thing you’d expect is a frozen air conditioner, right?

If your air conditioner freezes, there are many things to consider, but some tips and tricks can help you fix the problem on your own.

Why Your AC Unit Is Freezing

There are different signs of a frozen air conditioner.  The inside of your AC unit could be covered in ice. It may be blowing warm air, even when it is turned on. Or, maybe you noticed it’s just not working up to its usual standard.

Whatever the warning sign, a frozen air conditioner could be attributed to different factors. These include:

  • Restricted airways and vents in your AC unit
  • A condensate drain not working properly
  • Inadequate fan speed
  • Low refrigerate levels or a refrigerate leak
  • And more

Some of the listed reasons are more serious than others. While some issues require contacting an HVAC professional, there are some steps you can take to resolve the problem yourself.

First Steps When Your Air Conditioner Freezes

The first thing you’ll want to do when your air conditioner freezes is: turn it off. Running your frozen AC unit could damage important parts and make for an expensive repair in the future. Once the unit is off, you can turn the blower or fan back on. This could help speed up the process of thawing out the evaporator coils. These coils are the actual component of the unit that freezes if air is not properly circulated in the air conditioner.

Do not attempt to remove any ice or buildup on the coils by hand. Damaged coils could also result in costly damage to your AC.  As the blower works to warm the coils, try and remove any excess water that gathers inside the unit. You can do this with a shop vac on a central air conditioner, or tilt and drain standing and window units.

After the evaporator coils have been thawed and the unit is dry, it’s important to search for the cause of the problem.

How to Fix a Frozen Air Conditioner

There are many things you can do to prevent your AC unit from freezing. Using these tips and methods, you could fix your frozen air conditioner.

  • Change the air filter. A dirty air filter will prevent warm air from circulating and keeping the coils from freezing.
  • Clean the evaporator coils. This is the component of the unit that literally freezes. It’s important to keep coils clean of dirt and dust. Carefully brush coils to remove unwanted debris.
  • Clear supply vents and registers. If the registers and vents in your home are blocked or plugged, it can cause issues that affect your main unit.

When to Call a Professional for AC Repair

If you complete the above steps and your AC unit is still blowing warm air, or not reaching the desired temperature, it is time to contact a professional for air conditioner repair.

Your air conditioner freezing could be the result of low refrigerant (or a refrigerant leak), or the unit’s fan not blowing enough air to keep the coils from freezing. Either way, contacting a professional is the easiest and most convenient way to get your AC back in working (and cooling!) order.
