Frozen Coils — Gastonia AC Problem

Urgent — Act Now

Ice on the evaporator (indoor) coil or refrigerant lines is a clear warning. Common causes: clogged air filter, blocked return vents, failing blower motor, or low refrigerant from a leak. When the coil freezes, airflow drops further and the compressor can be damaged if the system keeps running.

What to Do

• Turn the system off at the thermostat (and breaker if needed)
• Do not chip ice off the coil
• Allow the system to thaw; check and replace the filter if dirty
• Call for professional diagnosis — especially if ice returns after restart

In Gastonia humidity, frozen coils often point to refrigerant issues that need proper leak detection and repair, not just a filter change. See also: Refrigerant Leak Repair and Emergency AC Repair.
