Frozen evaporator coils from high humidity
Why it happens here
Lakefront homes near Lake Nona Yacht Club see relative humidity above 70 percent most of the year. When the AC runs constantly, the coil temperature drops below freezing and condensation turns to ice. Dirty air filters make it worse by restricting airflow. The system stops cooling and you see ice on the lines.
Our approach
We do not just thaw the coil. We find the cause. We check the air filter, measure static pressure, and verify refrigerant charge with a manifold gauge set. If the system is oversized, we adjust blower speed. We also recommend a whole-home dehumidifier for lakefront properties.
