My Air Conditioning Unit Froze Over-- Now What Do I Do?!?
Frozen coils happen when the temperature inside the unit drops too low, causing moisture to freeze on the evaporator coil. This usually points to a problem with airflow, refrigerant levels, or drainage.
Common causes include:
1. Restricted Airflow
A dirty air filter, blocked vents, or a malfunctioning fan can prevent warm air from flowing over the coils—causing them to get too cold and freeze.
2. Low Refrigerant
Low refrigerant reduces the pressure inside your AC system. That causes the coil temperature to drop dramatically, freezing condensation on the surface.
3. Refrigerant Leak
If there's a leak in the refrigerant line, your system won’t have enough refrigerant to function properly—leading to icy coils and poor cooling performance.
4. Clogged Condensate Drain
If the drain line is blocked, water can build up around the coil and freeze instead of draining properly.
Will My AC Run If the Coils Are Frozen?
Technically, yes—but you absolutely should not run it. A frozen coil means your air conditioner can’t cool your home properly. Worse, running it while frozen can damage the compressor and lead to expensive repairs.

Why Is There Ice Build-Up in My Window Air Conditioner?
Ice on your AC is never normal. It’s a warning sign of a deeper issue like:
-
Airflow blockages
-
Low refrigerant
-
Drainage problems
-
Component failure (like a stuck fan or thermostat issue)
