AfterHVAC Company in San Francisco, CA
San Francisco’s fog-cooled climate and century-old housing stock create HVAC challenges you won’t find anywhere else in California. Most homes here were built without ductwork, without central air, and sometimes with only a gravity floor furnace set into a 120-year-old subfloor. We’re Brandt HVAC, and we specialize in the jobs other contractors turn down: fitting modern heating and cooling into Victorians and Edwardians that were never designed for it. If your system quits or you’re finally adding AC to a Mission District flat or an Outer Sunset row house, call us at (984) 538-9003. A live person answers, day or night.
Why San Francisco Homes Are Different
The marine layer dominates everything. In the Outer Sunset and Richmond District, summer temperatures rarely crack 65°F, which means cooling load is essentially zero but heating runs ten months a year. Meanwhile, a south-facing Victorian in Potrero Hill or the Mission can bake to 85°F indoors on the same July afternoon. Two completely different systems, sometimes within a few miles.
Most of our housing dates to 1880 – 1915. These wood-frame row houses have plaster walls, shallow crawl spaces, and no ducting. Running new ductwork often means cutting through lathe and plaster that crumbles, or navigating seismic soft-story retrofits that have already claimed the garage ceiling space where we’d normally route linesets. And then there’s the DBI permit process, which is famously detail-oriented. We’ve spent weeks coordinating with structural engineers just to decommission an old floor furnace in the Haight-Ashbury because the subfloor couldn’t support a modern unit without reinforcement.
Salt air from the Pacific corrodes outdoor coils faster than anywhere inland. A condenser in the Sunset District ages differently than one in Walnut Creek. We factor that into every equipment recommendation.
Our Main San Francisco Services
San Francisco homeowners call us most often for these three jobs, each handled differently here than in standard suburban construction.
AC Repair in San Francisco
Most “AC repair” calls in San Francisco are actually ductless mini-split issues: refrigerant leaks at the lineset penetration through old siding, failed inverter boards in compact outdoor units squeezed into tight yards, or drainage clogs from condensate pumps working overtime in humid fog conditions. We stock inverter compressors and flare fittings sized for the Daikin, Mitsubishi, and Bryant systems common in local retrofits. Every repair starts with a written price and ends with a 365-day guarantee. AC Repair in San Francisco
Furnace Repair in San Francisco
Gas furnace work here means navigating gravity floor furnaces in Inner Richmond Victorians, wall furnaces in 1920s Sunset apartments, and modern high-efficiency condensing units shoehorned into former closet spaces. Igniter failures, limit switch trips from restricted airflow in tight installations, and heat exchanger cracks in salt-corroded cabinets are the usual suspects. We carry OEM igniters and flame sensors for Rheem, York, and Bryant units, and we’re experienced with the venting challenges of tight San Francisco side yards. Furnace Repair in San Francisco
AC Maintenance in San Francisco
Maintenance in this city means cleaning salt residue from coastal coils, checking condensate drainage in high-humidity microclimates, and verifying that mini-split lineset insulation hasn’t degraded where it passes through old wood siding. Our tune-ups include a written report on what we found, not a sales pitch for what you don’t need. Technicians aren’t paid commission on replacement recommendations. AC Maintenance in San Francisco
