Why Central AC Coils Freeze Up in Houston Summer Heat
It sounds paradoxical, but central AC evaporator coils frequently freeze into solid blocks of ice when outdoor temperatures hit 95 degrees. A severely dirty air filter or low R-410A refrigerant charge causes coil surface temperatures to drop below 32 degrees Fahrenheit. As moisture condenses from humid air, it freezes across the coil fins, blocking all airflow into your living rooms.

Frequently Asked Questions
Turn the thermostat cooling mode to OFF immediately and switch the fan setting to ON. This allows indoor air to thaw the ice without burning out the compressor motor. Do not scrape ice off the coil fins as delicate aluminum can be punctured.
Continuous running is usually caused by low refrigerant from a pinhole leak, a failing blower motor operating below target RPM, or undersized equipment struggling against extreme attic heat loads.
