Diagnose and repair heat pump thermostat failures — no power, wrong readings, communication faults, or dead equipment.
We test power at the thermostat base, check wiring connections, and confirm communication with the indoor unit.
We trace thermostat wires for breaks, shorts, or loose connections at both the thermostat and the furnace/air handler.
Loose wires are reconnected, faulty thermostats are replaced with a compatible model, and system settings are restored.
We verify the thermostat controls both heating and cooling modes and all stages operate correctly.
Yes — if the thermostat isn't working, the heat pump won't run at all. We can usually fix or replace it on the first visit.
Basic thermostat swaps are doable, but heat pump systems require correct wiring for reversing valves, auxiliary heat, and staging. Incorrect wiring can damage the system.
We document your settings before any swap and will re-program a new thermostat to match your schedule and preferences.
We respond quickly to restore your heat pump fast.
