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.
Campbell mini-splits often serve Downtown bungalows with little attic space, plus ADUs and garage conversions in neighborhoods like Hamann Park and San Tomas.
Condensate lines on older bungalows can clog or lose slope. HAXX clears the line, checks any pump and confirms it drains.
Blinking lights and communication codes often trace to a board, sensor or interconnect wire, not a dead system.
Mitsubishi Electric, Daikin, Fujitsu, LG, Carrier and other ductless brands.
