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.
NOVATO DETAILSHeat pump service
Heat pump service
across Novato.
Novato grew fast after World War II, so many heat pumps here were added to tract homes built for gas furnaces. Tight attics, long duct runs and older wiring shape most repair calls.
01
Postwar tract homes
In San Marin, Ignacio and older tracts near downtown, retrofitted air handlers often show clogged drains, leaky ducts and refrigerant loss at the coil.
02
Hamilton and newer builds
Homes built on the former Hamilton Air Force Base are newer, but control boards, sensors and outdoor fan motors still wear out.
03
Wiring checked too
HAXX holds C-10 and C-20 licenses, so tripped breakers, disconnects and low-voltage faults are traced on the same visit.

GOOD TO KNOW
Heat Pump Repair in Novato: questions, answered.
My Novato heat pump keeps icing over. What causes that?
Some frost is normal and clears in defrost. Heavy ice usually points to a failed defrost sensor or board, low charge or a fan problem. HAXX tests each one.
Do you service mini-split heat pumps in Novato?
Yes. HAXX repairs single-zone and multi-zone ductless heat pumps along with ducted systems.
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.
