We service both PSC and ECM motor types. This is one of the most requested HVAC repair calls we get across San Dimas, CA.

Circuit Board & Control Diagnostics

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.

Hvac Repair FAQ

Why did my HVAC system just stop working with no warning?+

Most 'no warning' failures actually had small symptoms beforehand, like short cycling or a faint hum, that got missed.

Is it worth repairing an older system or should I replace it?+

We'll give you an honest read on remaining lifespan and repair cost versus a new install quote, not a sales pitch either direction.

Do you carry parts on the truck or will I need a second visit?+

Our vans stock the capacitors, contactors, igniters, and control boards behind most common failures.

How fast can a technician actually get to San Dimas?+

Call dispatch directly for a live estimate on arrival time.

What does the flat-rate price actually include?+

Diagnostic time is built into the quote, not billed separately.

Is there an after-hours fee for emergency calls?+

We'd rather lose a job on price transparency than win one on a hidden fee.
