Heat Pump Repair for Systems That Work Both Ways

A heat pump has to do two jobs from one set of parts, so it can fail in ways a cooling-only system never does. It might cool fine and refuse to heat, heat fine and refuse to cool, run constantly in mild weather, or ice over and never clear itself. Heat pump repair means testing the system in both modes rather than confirming one of them works and stopping there.

Faults Specific to Heat Pumps

• Reversing valves that stick or fail to shift between heating and cooling
• Defrost boards and sensors that leave the outdoor coil iced over
• Auxiliary heat strips that run when they should not, driving up the bill
• Thermostats that are not configured for heat pump staging
• Low refrigerant charge, which hurts heating capacity before cooling
• Compressor and contactor failures
• Outdoor fan motors and crankcase heater faults

The Symptoms Customers Notice First

Most heat pump problems announce themselves as a comfort complaint before they become a breakdown. Air from the vents feels lukewarm rather than warm. The outdoor unit runs but the indoor temperature drifts. The electric bill jumps because backup heat is carrying the load the compressor should be handling. Any of those is worth a diagnosis, since a heat pump limping along on auxiliary heat is expensive to run.
