Why Heat Pump Repair Matters in Davis
Davis has more heat pumps every year from new all electric homes and furnace swaps. Fog season frost on outdoor coils puts the defrost system to work from November to March.
-
More heat pumps on the street: New homes and furnace swaps add units that now need service.
-
Fog season frost: Morning fog coats the outdoor coil, and the defrost system cycles often.
-
Hard summers too: The same unit cools through 15 to 20 days at 100°F or more.
-
Winter bills: A unit that cannot heat well leans on backup heat strips, and bills climb.

Phone triage: You tell us what the unit is doing, and we flag any urgent safety points.
-
Error codes: We read any codes on the thermostat, indoor unit or outdoor board.
-
Both mode tests: We run heat and cool and compare the results.
-

Heat Pump Problems We Fix
Heat pump problems look different from AC or furnace problems. These are the ones we see most.
-
Weak heat in winter: A system that runs but only blows lukewarm air may have low refrigerant, a dirty coil or a sensor fault. We test before we guess, and heat pump not heating davis calls start here.
-
Ice that will not melt: A coil can frost up in fog season. If the ice stays thick after the defrost cycle, a defrost board, sensor or reversing valve may have failed.
-
Stuck in one mode: The unit heats when you want cooling, or the other way round. A stuck reversing valve or a bad control signal is a common cause.
-
Loud defrost noise: A whoosh or a thump during defrost can be normal. A loud grinding or banging sound points to a worn fan motor or a failing part.
-
Mini split error codes: A blinking light on a wall head often means a sensor, board or communication fault between the indoor and outdoor units.
-
High winter bills: A heat pump that cannot keep up leans on backup heat strips, which use far more power than normal heating does.
