How To Thaw A Frozen AC

Nothing beats coming home to a cool house—so if your AC freezes up on a hot day, it’s more than inconvenient; it’s uncomfortable. A frozen AC isn’t trapped in a block of ice, but rather has moisture that freezes around its coils, causing the system to lose efficiency and stop cooling effectively. At Baldwin Cooling, Heating, Plumbing & Electrical, we’re here to help you resolve the issue quickly! Here’s how to safely thaw a frozen AC unit and get it back in action.


Common Causes of a Frozen AC

Understanding why an AC freezes can help you prevent it from happening again. Here are some common causes:

1. Blocked Airflow

When airflow is obstructed, warm air can’t circulate around the evaporator coils, causing them to freeze. Clogged air registers or a dirty air filter can reduce airflow, preventing proper heat exchange. Without ventilation, coil temperatures can drop below freezing, leading to ice buildup.

2. Faulty Blower Fan

The blower fan keeps air circulating, helping maintain even temperatures throughout the system. When it stops working, cold air becomes denser and can’t move through your home effectively. This can lead to frozen refrigerant lines, causing a blockage in air circulation and creating icy coils.

3. Low Refrigerant Levels

If refrigerant levels are low, your AC loses efficiency, leading to temperature drops below freezing on the evaporator coil. This causes humidity to freeze on the coils, affecting the system’s ability to cool your home.


Steps to Thaw Your AC

Fortunately, you can safely defrost your AC unit at home. Follow these steps:

  1. Turn Off the Thermostat
    Begin by switching off your thermostat to stop the cooling process and prevent more ice from forming.
  2. Turn On the Fan
    Set the fan to “ON” to help circulate air and thaw the ice. This process may take up to 24 hours.
  3. Dry the Coils
    After the ice melts, gently dry the coils with a towel to remove any excess moisture.

If the problem persists, there may be an underlying issue with your system that requires professional attention. Baldwin’s technicians can inspect your AC and provide the necessary repairs to keep it running smoothly.

Excellent install of a generator by Jake & Ryan. They went over and above, working late waiting for the utility inspector to come out for final inspection. Couldn’t be happier…these guys are the best.
