FAQs

A: The two most common causes are low refrigerant from a leak and restricted airflow from a dirty filter or coil. DC's high humidity means the evaporator coil has more moisture to remove — making it more vulnerable to freezing when either issue is present.

A: Yes. Switch to fan-only mode to thaw the coil before calling. Running the system while frozen can damage the compressor in San Diego heat.
