Residential Heat Pump Repair in Tallahassee

Heat pump specific problems

• Reversing valve stuck or failing, so the system delivers heat in cooling mode or cool air in heating mode.
• Defrost control board or sensor faults causing odd winter behavior.
• Auxiliary or emergency heat strips running when they should not, driving up electric bills.
• Outdoor unit icing in winter and failing to clear on a defrost cycle.
• Thermostat configured for a conventional system rather than a heat pump.
• The same shared failures as any AC: capacitors, contactors, fan motors, refrigerant leaks and compressors.

Cooling season symptoms

In summer a heat pump behaves like a standard air conditioner, so no-cooling complaints look identical: warm air, long run times, ice on the lines, or an outdoor unit that will not start.

The extra diagnostic step is confirming the reversing valve is actually in the cooling position, since a valve issue produces symptoms that otherwise make no sense.

Winter behavior worth knowing

On cold mornings, a heat pump outdoor unit will frost and then run a defrost cycle — steam rising off the unit is normal, not a fire. Brief lukewarm air during defrost is also normal.

What is not normal is heavy ice that never clears, or the system relying on backup electric heat strips for extended periods on mild days.

Efficiency considerations

Because heat pumps run in both seasons, their annual runtime is high. That makes maintenance more valuable than on a cooling-only system, and it makes airflow and refrigerant charge accuracy matter more for operating cost.
