Every job starts with a real diagnosis, not a guess — here's the full scope of what our HVAC repair technicians handle across Cupertino, CA.

Refrigerant Leak Detection
Topping off refrigerant without finding the leak just delays the same failure. Techs handling refrigerant leak detection carry the specific parts and tools this job calls for, not a generic kit.
Blower Motor & Fan Repair
A blower that hums but doesn't spin, or one that's pulling excess amperage, gets tested under load, not just visually inspected. Techs handling blower motor & fan repair carry the specific parts and tools this job calls for, not a generic kit.

A blown board is sometimes a symptom of a bigger electrical issue we'll flag. This is one of the most requested HVAC repair calls we get across Cupertino, CA.
Thermostat & Wiring Troubleshooting
We check low-voltage wiring runs end to end before assuming the thermostat is the culprit. Techs handling thermostat & wiring troubleshooting carry the specific parts and tools this job calls for, not a generic kit.
