Lennox Heat Pump Defrost: What Florida Homeowners Hear
lennox
Cold fronts still hit Tampa Bay. Heat pumps reverse for defrost; manufacturer education helps you tell normal operation from a service call.
Why defrost exists
During heating, outdoor coils can frost. Heat pumps temporarily reverse to melt ice—normal behavior discussed in manufacturer owner education, including Lennox residential heat pump resources. You may hear a whoosh, see steam, or feel brief cool air at registers.
When it’s not normal
Ice that never clears, no heat for long periods after mild weather, or frequent emergency heat use can indicate airflow, charge, sensor, or control issues. Refrigerant diagnosis requires EPA Section 608 certified technicians.
