Why Does My Air Conditioner Freeze?

Although it might seem strange that an air conditioner can freeze, it’s a very common problem during the summer months. Let’s break down why this happens, how to fix it, and what you can do to prevent it from happening again.

Why Does My AC Freeze?

When an air conditioner freezes, it’s most likely because there is little to no airflow around the evaporator coils. When evaporator coils get dirty, the barrier of dust and debris on them keeps the refrigerant inside from raising its temperature. As a result, condensation gathers on the coils and eventually freezes them, leaving your AC unable to cool the home.

How to Thaw Your Frozen Air Conditioner

If your AC freezes, there’s no need to call a technician. Simply follow these simple steps to thaw your AC:

Step 1: Turn your thermostat off and your fan on, and wait for the ice to thaw.

Step 2: Check your air filters while you wait, replacing it if it’s dirty.

Step 3: Once the ice is completely thawed and the coils are dry, you can turn your AC on again.

Remember that it’s always a good idea to call a professional if you’re uncomfortable performing these tasks on your own.

What Can I Do to Prevent a Frozen AC?

Preventing a frozen AC is actually quite easy. Change your air filter every few months during mild weather and more often during the summer and winter months. By doing this, you can prevent clogged air filters, which reduce air flow to the coils and allow dust to settle on them. Additionally, a tune-up on your AC two times each year will let you know if your coils are dirty and prevent other problems from going unnoticed.

Should I Call a Professional?

As mentioned above, calling a professional is a good idea if you aren’t comfortable thawing your AC on your own. You should also call a technician if your AC freezes frequently. This indicates a need for actual air conditioning repairs, which might be related to the system’s refrigerant levels.
