Heat pumps in Hillsborough fail differently than a furnace or straight AC — a stuck reversing valve, an incomplete defrost cycle, or auxiliary heat that won't kick in all need specific diagnostic steps. We're trained specifically for heat pumps, not just general repair.
General HVAC techs are often less confident with heat pumps since the reversing valve, defrost board, and aux heat strips don't exist on a standard split system. We test each component specifically, since a heat pump issue in January often has nothing in common with the same symptom in July.
What sets a heat pump specialist apart.
Catching what often gets misdiagnosed as a compressor failure.
Whether defrost won't start or won't stop, we test the board and sensors.
We test the physical heating elements and the control logic that decides when to fire them, since a fault in either one produces the exact same symptom.
Winter and summer get equal attention here.
Different brands handle defrost logic differently, and our techs train on the specific systems common in Hillsborough, CA.

What Hillsborough heat pump owners ask most.
Nine times out of ten this points to a reversing valve stuck in the wrong position, though we still check refrigerant charge since it can mimic the same symptom.
If it never melts back on its own, that's the signal something's wrong.
Nine times out of ten it's a wiring or staging problem between the thermostat and the control board, and we check that connection directly.
These two components simply don't exist on a conventional system.
Not just during summer AC demand.
We verify in both modes since the system runs two ways.
We train on the specific brands common in Hillsborough, CA.
Not inherently, though the auxiliary heat strips see more use in harsher climates and are worth checking during maintenance.
Regular tune-ups extend that window meaningfully.
