How To Fix A Frozen Air Conditioner?

What happens if your air conditioner malfunctions and you’re left with a frozen unit?

It might seem strange for a heating system to freeze during the summer, but it happens every year to many homeowners without proper preparation. If your air conditioner freezes on a hot day, you will be uncomfortable. Learn how to solve the problem of an AC unit that is frozen and how to identify one:

Reasons Why The Air Conditioner Gets Frozen?


1. Insufficient Airflow

Clogged or leaky ductwork is another cause of poor airflow, which requires duct cleaning and sealing. The unit will have to work harder to reach the same comfort level if its filters are clogged.

2. Refrigerant Levels are Low

The refrigerant levels can also be too low, resulting in freezing. This problem can be identified by ice along the refrigerant line in your air conditioner.

3. Problems With the Fan

During normal use and operation, fans can get dinged or worn out. The AC fan can be knocked off the balance if a larger object travels through your system.

4. Faulty Evaporator Coils

Hair, pet dander, dust, dirt, and mold all get filtered out by your air conditioning unit. Although your AC filter catches a lot, the evaporator coils in your system can accumulate a lot of dust over time.

How to Fix a Frozen Air Conditioner?

  • Step 1

A frozen air conditioner needs to be turned off at the breaker box. To turn off your central air conditioner, turn the off switch on your electrical panel. Frost removal can take a few hours or up to a few days. It would help if you did not try to remove the ice from your air conditioner. Trying to do so may damage your system. If any water has collected around the unit after it thawed, you can remove it.

  • Step 2

When an AC unit is frozen, the coils must be dried by turning on the fan or blower. Turning on the power and setting the thermostat for only operating the fan makes it possible only to operate the blower. A hairdryer can remove moisture from your air conditioning system if it has frozen coils. Overheating an air dryer can damage the coils.

  • Step 3

Ensure your air filters are clean and replace them if necessary. We check your condenser’s coils and fins to see if dirt and debris are preventing airflow. To clean coils in that case, use a soft brush. A refrigerant leak will require specialized tools and equipment to fix. For help with this type of project, hire a licensed HVAC technician for air conditioning services in Allentown, PA.

  • Step 4

Now that you have unfrozen and addressed any AC unit errors, it’s time to restore power. Set your thermostat to the desired temperature after switching the breaker back on. Cool air should start coming out of the vents within a few minutes. A professional HVAC technician for AC repair in Allentown, PA, should be contacted if your air conditioner does not reach the desired temperature or is blowing warm air.
