You might be surprised to find out your air conditioner can freeze up, even when it feels scorching outside. Frozen air conditioners won’t be able to cool your home properly — and can cause further damage to the unit — so you need to get to the bottom of the issue ASAP.

Here are a few reasons why air conditioners freeze up in the summer and how to fix a frozen AC unit:

Dirty Air Filters

Over time, your AC air filters will collect a lot of dust, dirt, and debris. Clogged filters can strain your HVAC system by making it harder for air to pass through. Your AC works by cooling the warm air that passes over the coils. If the air filters are clogged, the warm air can’t get in and the cold air will be trapped. This causes the coil to get too cold and freeze.

You should change your air filters every three to six months, depending on the manufacturer’s recommendations. If you don’t feel comfortable doing this yourself, schedule air filter replacement services with a local HVAC pro.

Clogged Drain Lines

Condensation collects inside your AC unit and needs a way out through the drain line. If the drain line becomes clogged, the water will be stuck inside the unit, and the air conditioner could freeze. The condensation can also cause mold growth, water damage, and compressor issues, so it’s important to clear any clogs quickly.

Unclogging the drain line is a job best left to an experienced HVAC technician. Once the line is clear, the condensation can leave the air conditioner, and the system can function properly.

Refrigerant Leaks

Refrigerant absorbs the heat in the air that passes through your AC unit. If the refrigerant line is leaking, your air conditioner won’t be able to regulate the temperature properly. This can cause the evaporator coil to freeze and put serious strain on your air conditioner.

If you suspect that your refrigerant is leaking, you need to schedule refrigerant line repairs right away. A knowledgeable HVAC contractor can locate the source of the leak, replace the tubing, refill the refrigerant to a safe level, and test your system to ensure it runs correctly.

Slow or Broken Fans

The blower fans circulate air throughout the AC system and into your home. They also blow air over the evaporator coils to prevent overheating. If the fans are broken, condensation will form on the coils and eventually freeze.

Broken fans are often caused by poor electrical connections, faulty motors, or obstructions. An expert HVAC technician can identify the cause of a failing fan and provide the right repair.
