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.
PLEASANTON DETAILSHeat pump repair
Heat pump repair
for Pleasanton homes.
Pleasanton heat pumps work hard in both directions: cooling through long, dry Tri-Valley summers and heating on frosty winter mornings. That steady use shows up as worn parts.
01
Summer strain
Compressors, capacitors and outdoor fan motors take the most wear during Pleasanton heat spells. Each part is measured before anything is swapped.
02
Winter defrost problems
Ice that does not clear, or a system that blows cool air on cold mornings, often points to a defrost board, sensor or reversing valve.
03
Breakers and controls
HAXX holds C-10 and C-20 licenses, so tripped breakers, disconnects and thermostat wiring are diagnosed by the same visit.

GOOD TO KNOW
Heat Pump Repair in Pleasanton: questions, answered.
Why is my Pleasanton heat pump blowing cool air in heat mode?
A stuck reversing valve, a failed defrost control, a bad sensor or a low refrigerant charge are the usual causes. HAXX tests each one before quoting.
Which heat pump brands do you repair?
Most major ducted and ductless brands, including American Standard, Mitsubishi Electric, Daikin, Carrier, Trane and Lennox.
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.
