Why San Francisco homes get this: The cool, foggy maritime climate means central AC is rare and rarely needed, so HVAC work centers on heating efficiency, ventilation, and increasingly heat-pump retrofits driven by Title 24 energy rules. Older homes often have undersized or outdated heating systems requiring careful upgrades.

By national ratios San Francisco supports about 1,200 full-time HVAC technician pros — a large market with room for niche specialists, emergency-only operators and franchises alike. That is larger than most United States cities we cover. Only 39 % of homes are owner-occupied: landlords, building managers and housing associations place much of the work, often as recurring contracts. The housing stock is old for the country, which pushes repair and replacement demand above the national average.
