Heat pump repair in Nashville, TN, same day.
Heat pumps are their own animal. Reversing valves, defrost boards, aux heat sequencing, refrigerant charge - they fail in ways a straight AC or gas furnace never does. Our Nashville trucks carry the parts to diagnose and fix on the first visit.
Heat Pump Repair done right, the first visit.
Reversing valve failures
Heat pump stuck in heat or cool mode is almost always the reversing valve or its solenoid. We diagnose, replace, and recharge in one visit.
Defrost board problems
Frozen outdoor coil in winter is usually the defrost control board or sensor. Stocked on the van, replaced same day.
Aux / emergency heat
Strip heat that won't sequence, emergency heat running full time, high electric bills. Diagnosed and fixed, not patched.
Refrigerant leak repair
Electronic leak detection, proper repair, then recharge to manufacturer spec. Not a top-off that fails next season.
Dual-fuel systems
Heat pump with gas furnace backup. Balance points, thermostat staging, and changeover issues fixed properly.
Flat-rate pricing
Every repair is quoted by the job before we start. White Glove Members pay a flat $49 diagnostic.

Nashville's winters are the sweet spot where heat pumps work hardest and fail loudest. Average January lows sit in the upper 20s, which is right at the edge of where a standard air-source heat pump has to switch to auxiliary heat and where the defrost cycle runs constantly. That combination puts more thermal and mechanical stress on reversing valves, defrost boards, and compressors than a heat pump in, say, Atlanta or Chattanooga would ever see. If a component was marginal in September, it's usually broken by Christmas.
The other Nashville-specific issue is the mix of home vintages. Older East Nashville, Sylvan Park, and Berry Hill homes were retrofitted with heat pumps long after they were built, often with undersized returns and duct runs in unconditioned crawl spaces. That kills static pressure, freezes the outdoor coil faster than it should, and burns out defrost controls. Newer builds in The Nations and 12 South have modern equipment but tight envelopes - a small refrigerant leak that would be tolerable in a leaky house pulls indoor humidity up fast when the shell is airtight.
The five failures we see most in Nashville.
1. Reversing valve stuck in cooling. The system runs, air moves, but everything blowing out of the vents is cold in January. The reversing valve or its 24V solenoid has failed to shift. This is a same-visit fix if we have the valve on the truck for your brand.
2. Defrost board failure. Outdoor unit is a block of ice, indoor air feels weak, and aux heat is running constantly. The defrost control board or temperature sensor stopped triggering the defrost cycle. Standard part on our vans.
3. Aux heat running full-time. Electric bill doubled and the heat pump barely comes on. Usually a bad outdoor thermostat, wrong balance-point setting, or a control board that's given up on the compressor. Fixable in one visit almost every time.
4. Low refrigerant charge. The system runs but can't move heat. You feel the difference on the 20-degree mornings. Electronic leak detection, proper repair, then a recharge to spec - not a "top-off" that fails again next winter.
5. Failing capacitor or contactor. Compressor tries to start, hums, then quits. Cheap parts, quick fix, but the diagnosis has to be right so the underlying cause (usually high head pressure or dirty coils) doesn't take the replacement out with it.
