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.
HILLSBOROUGH DETAILSHeat pump repair
Heat pump repair
in Hillsborough.
Hillsborough homes are large, often 2,500 square feet and up on half-acre or bigger lots, so heat pumps here tend to be multi-system or multi-zone. A fault in one zone rarely means the whole house is down.
01
Multiple systems per house
Wings, upper floors and guest suites often run on separate equipment. HAXX tests each system and its controls instead of assuming one cause.
02
Long line sets and hillside pads
Outdoor units set downslope or far from the house mean long refrigerant runs. Leaks at flare joints and buried line sets are a common find.
03
Electrical side checked too
As a licensed C-10 electrician, HAXX checks disconnects, breakers and low-voltage control wiring on the same visit.

GOOD TO KNOW
Heat Pump Repair in Hillsborough: questions, answered.
Why is only one zone of my heat pump not working?
Usually a sensor, fan motor, board or communication fault at that indoor head or air handler. HAXX isolates the zone before replacing any part.
Do you repair dual-fuel systems with a gas furnace backup?
Yes. HAXX services both the heat pump and the furnace side, including the controls that switch between them.
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.
