SAN FRANCISCO DETAILS

Mini-split repair
in San Francisco.

Ductless systems are common in San Francisco retrofits. Damp coastal air and long line runs in older buildings bring their own repair patterns.

01

Fault codes and lost communication

HAXX reads the fault, then tests sensors, control boards and the wiring between indoor and outdoor units.

02

Water dripping indoors

Clogged drains, failed condensate pumps and poor line slope are the usual causes. Coils and blower wheels are cleaned during the visit.

03

Refrigerant leaks and fan motors

Flare joints, coils and line sets are leak-tested. Failed indoor and outdoor fan motors are replaced with matching parts.

What ductless brands does HAXX service?

Mitsubishi Electric, Daikin, Fujitsu, LG, Carrier, Gree and most other brands, including multi-zone systems.

My mini-split runs but does not heat. What causes that?

Often a refrigerant leak, a failed sensor, a dirty coil or a reversing valve problem. HAXX tests each before quoting a repair.

Which mini-split brands do you repair?
