What Makes an AC Unit Freeze Up? The Top 4 Reasons

What Makes an AC Unit Freeze Up? The Top 4 Reasons

Summers in Palatine, Illinois, can be brutally hot and humid. Let’s say it is the middle of summer, and your air conditioner has been working overtime to keep your home cool.

Suddenly, the unit stops working, and the room starts to warm up again. You may be wondering, what causes an AC unit to freeze up?

This post will discuss the top four reasons why your air conditioner unit may be freezing up. We will add tips on how you can fix the issue yourself!

1. Dirty Air Filter

Air filters are vital for trapping dirt, dust, and other airborne particles, so they don’t end up clogging your AC unit. However, if the air filter gets too dirty, it can restrict airflow and cause your AC unit to freeze. To prevent this, ensure to check and clean your air filter regularly.

2. Low Refrigerant Levels

When the refrigerant level in your AC unit is low, it can cause the coils to freeze. The refrigerant helps to cool the air, so when it’s low, the unit has to work harder to keep the house cool, which can cause the coils to freeze.

If you think your AC unit is low on refrigerant, you should call a professional to check it. They can add more refrigerants and get your AC unit to work correctly.

3. Clogged Condenser Coils

If you wonder why your HVAC system is icing up, one possible reason is that the condenser coils are clogged. The primary function of coils is to release heat outside, and when they’re unable to do that effectively, it can cause your AC unit to freeze up.

To prevent this, keep the area around your condenser unit clear of debris like leaves and dirt.

If you think your condenser coils might cause your AC unit to freeze up, contact a professional HVAC technician for help. They can clean the coils and get your system back up and running.

4. Defective Thermostat

The thermostat is vital for turning the AC unit on and off. If it is defective, it may cause the AC unit to freeze up.

If you think your thermostat may be the problem, you can try replacing the batteries or adjusting the settings. If that doesn’t work, you’ll need to call a professional to have it replaced.
