SAN MATEO DETAILSMini-split repair
Mini-split repair
in San Mateo.
Ductless systems are common in San Mateo Eichlers, ADUs and additions. Many problems come down to drains, sensors, boards or communication between units.
01
Error codes and communication faults
HAXX reads the code, then tests the boards, sensors and the wiring between indoor and outdoor units.
02
Leaks and drains
Water dripping from a head usually means a clogged drain line or pan. Refrigerant leaks are located before any recharge.
03
Cleaning and fan motors
Dirty blower wheels and coils cut airflow and cause odors. HAXX cleans them and replaces failing fan motors.
