Frozen AC Coil and AC Freezing Up in San Angelo, TX
A frozen indoor coil stops the AC from cooling and can damage the compressor if it runs too long. Ice on the refrigerant lines or the indoor coil is the telltale sign. Whether you call it a frozen coil or an AC freezing up, the problem is the same and the cause needs to be found.

Common Causes
Dirty Filter
A clogged filter restricts airflow over the coil, causing it to freeze.
Low Refrigerant
Low refrigerant drops the coil temperature below freezing. See refrigerant leak repair.
Dirty Evaporator Coil
A dirty coil cannot absorb heat properly and can freeze. See evaporator coil repair.
Blower Problem
A weak blower reduces airflow and can cause freezing. See blower motor repair.
When to Call for Service
Turn the AC off and let the coil thaw, then check the filter. If it freezes again, the cause is still there. Freezing is a symptom, not the root problem, so request service rather than simply melting the ice. Read why your AC keeps freezing.

Frequently Asked Questions
Why is my AC coil freezing?
Common causes include a dirty filter, low refrigerant, a dirty coil, or a blower problem.
Should I just melt the ice and restart the AC?
No. Melting the ice only clears the symptom. If the cause is not fixed, the coil will freeze again and repeated freezing can damage the compressor.
