Why Is My AC Frozen? And How to Fix it

Ice buildup on an air conditioner can be a challenging issue for homeowners, and the question we always hear is, “Why is my AC frozen.” A frozen AC can impact the cooling efficiency of your AC unit and cause potential damage and costly repairs if not addressed. Understanding the causes of this ice formation is crucial for resolving the problem and maintaining your air conditioning system’s longevity and optimal performance.

If you’re wondering how ice can form on your AC system despite record-breaking temperatures. The answer lies in one of the system’s main components – the evaporator coil.

What does the evaporator coil do?
An evaporator coil is part of an air conditioner or heat pump that absorbs the heat from the air in your house. It is located inside the air handler or attached to the furnace. The role of the evaporator coil is to hold the chilled refrigerant that the compressor moves into it.

As the air from the blower fan moves over the coil, the cold refrigerant removes the heat from your home’s air. The refrigerant becomes warmer and travels to the condenser coil outdoors.
