Air Conditioning Repair FAQ

Why does one room in my house never cool properly?+

Usually a duct or damper problem specific to that zone rather than a system-wide refrigerant issue.

My AC runs constantly but never reaches the set temperature — why?+

Constant running without recovery is not normal and shouldn't be ignored.

Do you service zoned HVAC systems?+

Yes — damper motors, zoning control panels, and the wiring between them are all within scope.

Is ductwork really part of an air conditioning repair?+

We check airflow as a standard part of central air diagnostics.

How is central air repair different from a window unit or mini-split fix?+

Central systems involve ductwork, zoning, and a much larger air-handling path, so diagnostics go beyond the outdoor unit alone.

How quickly can someone reach San Lorenzo for a total outage?+

Total outages during extreme heat get priority routing across San Lorenzo, CA.
