AC Unit With Evaporator Coil
Help! I Think My Evaporator Coil Has Frozen!

April 12, 2019

The AC unit in your Neptune Beach, Florida, home relies on many hard-working components. These all work together to help keep the temperature in your home comfortable. One component you may experience issues with is the system’s evaporator coil. A frozen evaporator coil can cause problems with the efficiency of the air conditioner in your home and potentially result in your system breaking down. Therefore, it’s important to schedule a professional repair as soon as you suspect or notice a problem.

What is an Evaporator Coil?

The evaporator coil in your AC unit or heat pump helps the system complete its heat exchange process. It does so by absorbing heat from the air inside the house.

Signs of a Frozen Evaporator Coil

Being vigilant about problems with your AC unit can help you prevent a small problem from becoming a large one. As a result, you can lower your risk of breakdown. A frozen evaporator coil may be your problem if:

  • You see ice forming around the outside refrigerant line.
  • There’s moisture around your air handler.
  • Your condensate drain pan is overflowing.
  • The air coming out of your supply vents is warm.

What Can Cause a Frozen Evaporator Coil?

Even if you get your evaporator looked at, you’ll also need to address the issue that caused the coil to freeze in the first place. Some of the most common reasons that evaporator coils freeze include:

A Dirty Coil

Dust and dirt can buildup up on and around your evaporator coils. This not only puts additional strain on your system. It also increases its risk of freezing. Scheduling regular maintenance can help keep your evaporator coils clean and functioning properly.

Refrigerant Leaks

Refrigerant leaks can come from wear and tear. They may go unnoticed for a long time. If your refrigerant is low, it can cause ice to build up on your coil. As a result, it can eventually freeze it.
