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.

GOOD TO KNOW
Heat Pump Repair in Colma: questions, answered.
Which heat pumps do you repair in Colma?
Ducted systems and ductless mini-splits from the major brands, including Mitsubishi Electric, Daikin, Fujitsu, LG and Carrier.
Why is my heat pump blowing cool air in heat mode?
Common causes are a failed reversing valve, a defrost control fault, a bad sensor or a low refrigerant charge. HAXX tests each before quoting.
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.
