There’s nothing more frustrating than turning on your air conditioner on a hot day, only to find that it isn’t working properly. One of the most common problems that can occur is frozen A/C coils. But what are frozen A/C coils, and what could be causing this problem? Read on to find out.

What Are Frozen A/C Coils?

The coils in your air conditioner are responsible for absorbing heat from the indoor air. This process is known as refrigeration, and it’s how your air conditioner can cool the air inside your home.

Frozen coils occur when the air around the coils gets too cold. This can happen for various reasons, which we will discuss below. As the coils get colder, they begin to ice over. Once the coils are completely frozen, the air conditioner will no longer be able to absorb heat, and the unit will shut down.

What Causes Frozen A/C Coils?

There are a few reasons your air conditioner’s coils might freeze. Here are some of the most common causes:

1. Dirty Air Filter

A dirty air filter is one of the most common reasons for frozen A/C coils. The air filter is responsible for trapping dust, dirt, and other airborne particles.

Over time, the air filter can become clogged with these particles. When this happens, the airflow to the coils is restricted. This can cause the coils to get too cold, which will cause them to ice over.

2. Refrigerant Leaks

Another common cause of frozen A/C coils is a refrigerant leak. Refrigerant is a vital part of the air conditioning process. It helps to remove heat from the indoor air and transfer it outdoors.

If there is a leak in the system, the refrigerant level will drop. This can cause the coils to get too cold, which will cause them to freeze.

3. Broken Fan Motor

If your fan motor is broken, it will not be able to circulate air around the coils properly. This can cause the coils to freeze over, as they will not be able to get rid of the excess heat.

There are a few ways to tell if your fan motor is broken. One way is to listen for a rattling noise from the air conditioner. This is a sign that the fan blades are not spinning correctly. Another way to tell is if the air coming out of the vents is not as cool as it should be.

4. Thermostat Issues

If your thermostat is not working properly, it can cause your air conditioner to freeze up. Thermostats are responsible for regulating the temperature in your home. If set too low, it can cause the air conditioner to run for too long and the coils to get too cold.

5. Blocked Condensate Lines

The condensate lines are responsible for carrying away the water produced during the cooling process. If these lines become blocked, it can cause the coils to freeze over.

Condensate lines can be blocked by dirt, dust, and other debris. If you suspect that your condensate lines are blocked, you should have them cleaned out by a professional.
