CUPERTINO DETAILSMini-split repair
Mini-split repair
in Cupertino.
Many Cupertino mini-splits were added to Eichlers and remodeled homes a decade or more ago. Clogged drains, failing sensors and communication faults are now common.
01
Fault codes and control boards
HAXX reads the fault code, tests sensors, fan motors and control boards, and checks communication wiring between the indoor and outdoor units.
02
Leaks of water or refrigerant
Water dripping from a head usually means a blocked drain or pump. Weak cooling often points to a refrigerant leak at a flare joint.
03
Deep cleaning
Dirty blower wheels and coils cut airflow and cause odors. HAXX cleans heads in place.
