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.
MOUNTAIN VIEW DETAILSHeat pump repair in
Heat pump repair in
Mountain View homes.
Mountain View has a lot of newer heat pumps, many installed in the last few years as homes moved off gas. That means more mini-splits, more multi-zone systems and more warranty questions.
01
Eichler mini-splits
Monta Loma and other Eichler homes have no attic, so most run on wall or ducted mini-split heads. Drain lines and line sets often run outside the walls and need a careful look.
02
Warranty first
Many Mountain View systems are still under manufacturer warranty. Have the model and install date ready, and HAXX will tell you what the warranty may cover.
03
Repair, or replace with a heat pump
If a repair does not make sense, a replacement in Mountain View single-family homes must again be a heat pump under the city's reach code, so the options stay focused.

GOOD TO KNOW
Heat Pump Repair in Mountain View: questions, answered.
Do you service heat pumps in Mountain View Eichlers?
Yes. HAXX repairs the ductless and ducted mini-splits common in Monta Loma and other Mountain View Eichler neighborhoods.
If my heat pump cannot be repaired, can I go back to a furnace and AC?
In Mountain View single-family homes, a replaced air conditioner must be a heat pump under the city's current reach code. HAXX will explain the options that fit the code.
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.
