When summer temperatures are at their highest in Southeast Michigan, there’s nothing more frustrating than losing your AC. If you start to experience issues, it could be that your AC is freezing up and not working properly. The easiest way to determine if this is the issue is to inspect your refrigerant line-set pipe. You may need professional AC repair if this or your evaporator coil has ice.
In this blog, the expert technicians at Robin Aire discuss what causes an air conditioner to freeze up and how to properly prevent these issues so that your comfort is never compromised during the warmest months of the year.

5 Reasons Your Air Conditioning Is Freezing
To adequately prevent your AC from freezing up on a sweltering summer day, you must first understand why air conditioning systems have these issues.
Reduced Airflow
Restricted airflow can cause humidity to settle on your coils, where it can freeze. A common cause of reduced airflow is dirty air filters. When these filters become clogged with debris, there isn’t enough air moving through your home to prevent your AC from freezing. Other issues like blocked or closed supply and return vents can also decrease airflow in your home.
Low Refrigerant Levels
The refrigerant in your system plays an essential role in regulating the temperature throughout your AC. When refrigerant levels are low due to a leak or another issue, the pressure in the system drops, and the refrigerant expands and becomes cold. This is what leads water vapor to freeze on the surface of your coils.
Clogged Condensate Lines
Your AC collects moisture from the air, and when it condenses, it drains out of your home through your system’s condensate line. However, a clog in this line prevents your system from sufficiently removing the excess water, allowing it to become trapped where it freezes on the evaporator coils.
Blower Fan Issues
If your blower fan isn’t working correctly and reduces airflow, it can freeze your coils. Without warm air being blown onto the coils, your AC will freeze, preventing the air conditioner from working properly.
Cold Summer Nights
Your AC cannot function properly when outdoor temperatures drop below 60 degrees. The air pressure will cause the system to freeze, especially if it’s run at these temperatures for prolonged periods.
Prevention Tips & Solutions for a Frozen AC
Having to thaw a frozen AC is frustrating and inconvenient. Prevent these issues from happening in the first place with these simple tips:
- Have your refrigerant levels checked regularly by a professional
- Change your air filters every one to three months and keep all registers and vents open
- Use a programmable thermostat to automatically shut off your system when outside temperatures drop below 60 degrees
- Inspect your condensate line regularly
- Ensure your fan is working properly and increase its speed
