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.
LOS ALTOS HILLS DETAILSHeat pump repair
Heat pump repair
in the hills.
Los Altos Hills homes sit on lots of an acre or more, often with a main house, a guest cottage and a pool house. Many run several heat pumps, each with its own wear pattern.
01
Multi-system properties
Separate zones for the main house, ADU and studio mean more outdoor units, longer line sets and more controls to test. HAXX checks each system, not just the one that failed.
02
Long runs and exposure
Outdoor units placed far from the house or on exposed slopes see more refrigerant joints, debris and weather. Leak checks and coil cleaning are part of the diagnosis.
03
Power after an outage
PG&E safety shutoffs can leave boards, breakers and sensors in a fault state. A licensed electrician on the same visit checks the circuit side too.

GOOD TO KNOW
Heat Pump Repair in Los Altos Hills: questions, answered.
Do you service heat pumps in Los Altos Hills guest houses and ADUs?
Yes. HAXX repairs heat pumps in main houses, detached ADUs, studios and pool houses, including multi-zone ductless systems.
Why does my heat pump stop working after a power shutoff?
Sometimes a control board, breaker or communication link does not recover cleanly. HAXX resets and tests the system and replaces failed parts if needed.
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.
