Mini-split repair
for every zone.
Wall, ceiling cassette and slim-ducted mini-splits that stop heating or cooling, leak water or show error codes. HAXX repairs single-zone and multi-zone systems from all major brands.
Error codes and blinking lights
Fault codes are read and traced to the sensor, board or communication wire behind them.
Water leaking from the head
Clogged condensate lines, failed pumps and dirty coils are cleared and the drain is tested.
Refrigerant leaks
Flare joints and line sets are leak-tested and repaired before the system is recharged.
Fans, motors and noise
Indoor blower and outdoor fan motors, capacitors and loose parts that cause rattling.
Cleaning and airflow
Filters, coils and blower wheels cleaned to restore output and stop musty smells.
FREMONT DETAILSMini-split repair
Mini-split repair
in Fremont.
Ductless systems in Fremont additions, ADUs and older homes fail in predictable ways: drains clog, sensors drift, boards fail and refrigerant slowly leaks out.
01
Error codes and communication faults
HAXX reads the code, then checks the indoor-outdoor communication wiring, sensors, control boards and fan motors behind it.
02
Leaks of water or refrigerant
Dripping heads usually mean a blocked drain or pump. Weak cooling or heating often means a refrigerant leak at a flare joint.
03
Cleaning
Dirty coils and blower wheels cut output and cause odors. A deep clean restores airflow on many older heads.
