Frozen evaporator coils from high humidity
Why it happens here
The air near Cypress Creek holds more moisture, so the evaporator coil runs wetter and colder than inland. A slightly dirty filter or a small charge issue is enough to drop the coil below freezing, and once it ices over, airflow stops and the compressor overheats.
Our approach
We never just thaw the coil and leave. We check filter condition, blower amp draw, and refrigerant charge to find the root cause. Then we verify the temperature split is back in the 18 to 22 degree range before we call the job done.
