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.
In Saratoga, ductless units often serve additions, bonus rooms, pool houses and ADUs that the main ducts never reached. Each one runs independently, so each can fail on its own.
A head that ignores the remote or shuts off early often has a failed receiver, room sensor or control board. HAXX tests each.
Pool houses and far wings mean longer line sets, where leaks and poor insulation reduce output. HAXX pressure-tests the run.
Mitsubishi Electric, Daikin, Fujitsu, LG, Carrier and other ductless brands.
