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.
LAFAYETTE DETAILSHeat pump repair
Heat pump repair
in Lafayette.
Lafayette summers often reach the high 80s and can top 100°F, and winter nights sometimes freeze. A heat pump here works hard in both seasons, so wear shows up in both modes.
01
Defrost and cold-weather faults
Frosted outdoor coils, failed defrost boards and stuck reversing valves are common on cold Lafayette mornings. Each part is tested before anything is replaced.
02
Summer overload
Long run times in heat waves strain capacitors, fan motors and compressors. HAXX checks electrical readings and refrigerant charge together.
03
Wiring and breakers
As a licensed electrician too, HAXX traces tripping breakers, disconnects and low-voltage control faults on the same visit.

GOOD TO KNOW
Heat Pump Repair in Lafayette: questions, answered.
Why does my heat pump blow cool air on winter mornings?
It may be in a defrost cycle, which is normal for a few minutes. If it lasts, a sensor, defrost control, reversing valve or low charge is likely. HAXX tests each one.
Do you repair heat pumps you did not install?
Yes. HAXX services most ducted and ductless heat pump brands in Lafayette homes.
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.
