Heat pump problems
we diagnose and fix.
Ducted systems, ductless mini-splits and multi-zone heat pumps. Tell us what the system is doing and we start the visit with that symptom.
Ice on the outdoor unit
Some frost in winter is normal. A unit that stays iced points to airflow, refrigerant or defrost-control problems.
Mini-split error codes
Blinking lights and error codes on Mitsubishi, Daikin, Fujitsu and other ductless systems, traced to the sensor, board or refrigerant issue behind them.
Short cycling and noise
Units that start and stop, rattle, hum or trip the breaker are checked for electrical, airflow and sizing problems.
Water leaks from indoor heads
Clogged condensate lines and drain pumps cleared and tested before water damages the wall.
Repair or replace advice
If the system is not worth fixing, you get the reasons in writing and options to compare, not pressure.
HALF MOON BAY DETAILSHeat pump repair
Heat pump repair
on the coast.
Half Moon Bay homes need heat far more often than cooling, so a coastal heat pump runs in heating mode for much of the year. Damp, salty air adds wear that inland systems rarely see.
01
Heating-mode faults
Defrost boards, reversing valves, outdoor sensors and low charge are the usual reasons a heat pump blows lukewarm air on a cold, foggy morning.
02
Salt-air wear
Corroded coil fins, rusted fasteners and pitted electrical contacts on outdoor units near the ocean are checked on every visit.
03
Power and controls
HAXX is also a licensed electrician, so tripped breakers, disconnects, surge damage after outages and thermostat wiring are handled in the same call.

GOOD TO KNOW
Heat Pump Repair in Half Moon Bay: questions, answered.
Why does my Half Moon Bay heat pump keep going into defrost?
Cool, humid coastal air makes outdoor coils frost more often. Frequent or failed defrost cycles usually point to a sensor, control board or refrigerant issue that HAXX can test for.
Do you repair heat pumps in Ocean Colony and Miramar?
Yes. HAXX services ducted and ductless heat pumps throughout Half Moon Bay, including Ocean Colony, Miramar, Arleta Park and Highland Park.
Is it worth repairing an older heat pump?
It depends on the fault, the refrigerant the system uses and the condition of the compressor and coils. HAXX explains the repair cost against replacement options so you can decide.
Do you repair ductless mini-splits?
Yes. HAXX services wall, ceiling cassette and ducted mini-split heads, single-zone and multi-zone.
