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 systems in East Palo Alto homes and ADUs run year-round. Dirty coils, blocked drains and communication faults are the most common reasons for a service call.
HAXX reads the manufacturer's fault codes, then tests sensors, control boards and the communication wiring between indoor and outdoor units.
Water dripping from an indoor head usually means a blocked drain or failed pump. Refrigerant leaks at flare joints are found and sealed before recharging.
Indoor coils and blower wheels collect dust and mold. Deep cleaning and fan motor replacement restore airflow.
