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.
Low refrigerant, a failed sensor, a stuck expansion valve or a control fault. Each is tested before a part is ordered.
Fault codes are read and traced to the sensor, board or communication wire behind them.
Clogged condensate lines, failed pumps and dirty coils are cleared and the drain is tested.
Flare joints and line sets are leak-tested and repaired before the system is recharged.
Indoor blower and outdoor fan motors, capacitors and loose parts that cause rattling.
Filters, coils and blower wheels cleaned to restore output and stop musty smells.
Ductless outdoor units in Vacaville sit in direct summer sun and dust. Heat and debris wear fan motors, boards and coils faster than in cooler Bay Area cities.
Communication errors, sensor faults and failed control boards are traced with the manufacturer's diagnostics.
Clogged drain lines that drip down the wall, and refrigerant leaks at flare fittings, are found and repaired.
Dirty indoor blower wheels and coils cut airflow. HAXX cleans them so the head cools at full capacity.
