What HVAC problems are most common in San Francisco?
In San Francisco, the most common issues are fog and humidity, historic building constraints, no central systems, and radiator heat. Seasonal demand tends to be heating dominant, minimal AC need except sunny neighborhoods. A proper visit checks airflow, ducts, electrical components, and refrigerant or combustion performance before recommending parts.
Why won't my AC or furnace turn on?
No-cooling and no-heat calls usually trace back to a tripped breaker or safety switch, a clogged filter, a failed capacitor, a bad ignitor, or low refrigerant - not always a full system failure. A proper diagnostic checks the electrical, airflow, and charge or ignition before quoting parts.

About San Francisco HVAC Service
Direct Answer
For HVAC service in San Francisco, the first question is usually neighborhood and building type. Foggy western neighborhoods often need heating and moisture control, while sunnier areas may need AC or ductless mini-splits. A useful visit checks filters, airflow, controls, condensate drainage, and whether ducts are practical in the home.
