HVAC in South San Francisco
Cooler marine air, still plenty of failed furnaces.
SSF does not cook like Pleasanton. Furnaces and heat pumps still fail. We come when the window is real.
No heat is usually an ignitor, flame sensor, pressure switch, or thermostat — not an automatic furnace replacement.
Use this as a field guide to HVAC South San Francisco, then book a visit if the house still misbehaves.
We test ignition, flame proving, inducer, and safety switches. Age is a data point, not a diagnosis.
We map HVAC South San Francisco to the actual failed part or design limit. Age of the system is a data point, not the diagnosis.
You approve any repair after the findings are written down. Diagnostic visits are a flat $69. New installation estimates are free in-home with a load calculation — not a number invented from square footage on Zillow.
“It’s 15 years old, you need a new system” without readings is a pitch. We show the failed part first.
A company that skips testing on HVAC South San Francisco will skip it on the next call too. We would rather lose a job than install the wrong thing.

Inland heat (Pleasanton, Livermore, Concord) and marine air (Alameda, Daly City) are different loads. A note written for Concord is not automatically right for a fog-belt house. We treat them that way.
