How often should HVAC be serviced here?

Once a year at minimum — a spring cooling check for inland heat, and a heating check before winter. Smoke seasons are hard on filters, so check them monthly when air quality is bad.

Heat pump or gas furnace in San Francisco?

Heat pumps are increasingly the answer: they handle San Francisco's mild winters efficiently, cool in summer, and align with the state's electrification direction. A pro can size one for your home and advise on panel capacity.

How do I keep wildfire smoke out of my house?

Seal the envelope's big leaks, upgrade to higher-rated filtration your blower can handle, and run the system on recirculate during smoke events. Leaky ductwork in attics and crawl spaces is often the biggest smoke pathway — a pro can test and seal it.

San Francisco sits in California's patchwork climate: mild coastal influence or hot inland valleys — sometimes both within a single metro — and HVAC needs change with the microclimate.

Electrification is the statewide direction: heat pumps replacing gas furnaces, with ductless mini-splits filling the gaps in older homes.

When heating or cooling trouble hits your San Francisco home — one room roasting while the rest of the house is fine — AirFlow HVAC connects you with an independent local HVAC pro. Tell us what is happening and we will match you with a pro nearby, fast.

Homes here, and the HVAC problems they get

Local housing notes

Older homes with no central air — prime mini-split territory.
Newer electrified builds with heat pumps as standard.
Coastal condos and apartments with aging through-wall or packaged units.
Sunset District stucco rowhouses where side-yard equipment must meet setback rules.

Common local HVAC issues

No-cooling older homes: coastal-era homes with no AC face hotter summers unprepared.
Gas-to-heat-pump conversions: electrification retrofits need proper sizing and duct evaluation.
Poor filtration: standard filters can't handle smoke season — upgrades need pro guidance.
Inland heat overload: valley heat waves push undersized or aging ACs past their limits.
Fog-belt moisture: persistent summer fog keeps outdoor equipment damp for months, accelerating corrosion on unprotected cabinets; coastal-rated coatings and regular rinses fight the decay.
Victorian retrofit challenges: ornate Victorians and Edwardians hide nooks where ducts cannot run and plaster walls that resist cutting; slim-duct or ductless systems thread through with minimal disruption.
Wind-driven rain intrusion: winter storms push rain sideways into louvers and vent terminations; storm hoods and proper flashing keep water out of equipment and wall cavities.
Soft-story seismic bracing: retrofit ordinances have many buildings under construction at once, filling the air with dust; protecting intakes and changing filters during nearby construction saves coils.
Radiator-to-heat-pump conversions: old steam and hot-water radiators pair poorly with modern controls; homeowners often keep radiators for charm while adding mini-splits for precise room control.

San Francisco FAQs

Usually duct design: long runs, crushed flex duct, or poor balancing starve distant rooms of airflow. A pro can measure airflow room by room and fix the distribution rather than oversizing the equipment.
