How to Prevent Frozen Evaporator Coils

Change your air filter on schedule — dirty filters are the #1 cause of frozen coils
Ensure all return air vents are open and unobstructed

If you see ice forming, turn the system off and switch to fan-only to thaw before calling for service

Expert Insights

Pro Tips: Frozen Evaporator Coils

Pro-level knowledge our network technicians use to diagnose and resolve this problem faster.

Verify Thermostat Settings

Confirm the thermostat is set to the correct mode (heat/cool), the target temperature is appropriate, and the battery is fresh.

Inspect Electrical Connections

Corroded or loose wiring causes intermittent failures and is a fire hazard. Always shut off power at the disconnect before any inspection.

Install a CO Detector

Place carbon monoxide detectors near HVAC equipment and sleeping areas. Gas furnaces with cracked heat exchangers are a primary residential CO risk.
