Heat pumps in Herald 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. Our techs train specifically on these systems, 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. A winter symptom and a summer symptom get tested separately.
Specialized knowledge for specialized equipment.
We test solenoids and refrigerant flow directly.
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 Herald, CA.
The failure points unique to this system type.
Tested directly, not assumed.
Outdoor coil ice that won't clear on its own usually means a defrost board or sensor problem.
Verified directly.
Because heat pumps run two directions, charge accuracy matters even more.
We clean, inspect, and test fan motor amperage.
We verify compatibility during service.

What Herald 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.
The signal isn't reaching the strips the way it should.
A heat pump tune-up covers ground a standard AC visit never touches, namely the defrost cycle and the reversing valve.
Not just during summer AC demand.
Not just the mode it's currently running in.
We train on the specific brands common in Herald, CA.
Climate affects wear patterns more than it affects overall lifespan.
