AfterFast, Reliable AC Installation Across San Francisco
AC installation in San Francisco typically runs $4,130-$8,850 for a complete system, and most jobs are scheduled within two weeks of the written estimate. That range reflects the real spread between a compact ductless unit for one floor of an Edwardian flat and a full central air retrofit into a detached Sunset home. We work the whole city, from the fog belt of the Outer Richmond to the afternoon heat of the Mission, and we size every job with a room-by-room load calculation, never square footage alone. Call (747) 966-3037 for a free estimate, and we’ll give you a written price before anything gets ordered.
We’re Meadowsweet Heating & Air, part of the Cedarwell family of HVAC companies. The name comes from a wildflower once strewn on floors to keep rooms fresh, and that standard shapes how we leave your home: shoe covers on, drop cloths down, and a photo of the clean-up sent before the crew walks out. Luis Serrano leads our installation teams across San Francisco, and he holds every job to the 365-Day Done Right Promise. If it’s not done right, we make it right. No runarounds.
Why Meadowsweet Heating & Air Is San Francisco’s Preferred AC Installation Company
San Francisco homes don’t behave like homes anywhere else. A Mission District flat can be ninety degrees while the Outer Sunset sits in fog, and an old Victorian with double-hung windows loses cool air through every gap. That’s why we send background-checked, uniformed technicians who know the difference between a Sunset stucco flat, a Noe Valley hillside house, and a Pacific Heights Edwardian with plaster walls you don’t want cracked open. Our crews follow the C.A.R.E. values code: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, Explain the price before the work. That last one isn’t a slogan. It’s a written price, in your hand, before anything starts.
We carry parts for nine major equipment brands, so when a San Francisco customer needs a Trane coil or a Goodman blower, we’re not waiting on a warehouse in Sacramento. Scheduling is coordinated from our San Francisco Bay Area office and crews are dispatched locally across the city. A live person answers our phone 24/7, including weekends and holidays. No voicemail queue. When your AC fails on the first hot Sunday of September, you’ll talk to a human who knows the city.
Furnace Installation in San Francisco
Furnace installation in San Francisco is rarely a swap-in-place job. Our housing stock was never built for forced air. Edwardian row houses ran on floor furnaces and gravity-feed gas units, which means adding or replacing a furnace often requires routing new ductwork through shallow crawl spaces and around shared party walls. A typical furnace installation here runs $175-$825 for repair work, while full replacements paired with an AC system fall within the $4,130-$8,850 AC installation range, depending on what the existing distribution looks like. We start with a load calculation and an honest look at your ductwork before we quote anything.
Retrofit into Older Homes
In a pre-1915 row house, the furnace right-of-way usually doesn’t exist. We’ve installed high-efficiency furnaces in Cole Valley homes where the only original heat came from a floor furnace in the hallway. The work involves running insulated trunks through a crawl space we’ve already mapped for clearance and slope, and sealing every joint. It’s slower than a garage swap, but it’s how a San Francisco furnace gets done right.
Furnace and AC Together
If you’re going to open a wall anyway, pairing a furnace with a central air or heat pump in the same scope saves on labor and keeps the ductwork sized for both. We’ll write one price that covers the full system, so you know exactly what the combined work costs before we cut anything.
HVAC Installation in San Francisco
HVAC installation in San Francisco means designing for a city where two addresses one mile apart have different cooling loads. We size equipment with a room-by-room Manual J calculation, not a rule of thumb, because an oversized AC in the Outer Sunset will short-cycle and rot from salt air, while an undersized one in Potrero Hill will run all afternoon during a Diablo wind event and still not hold 76 degrees. The $4,130-$8,850 range covers the equipment, the load calculation, the permits, and the labor, and we’ll tell you exactly where your job falls before anything gets scheduled.
Ductless Systems for No-Duct Homes
Most San Francisco homes have no existing ductwork, and opening plaster walls in a historic facade triggers DPW permit requirements. A ductless mini split installation avoids that entirely, and in fog-coastal zones we recommend corrosion-resistant coated coils on the outdoor units. For a two-bedroom Edwardian flat, this is often the smartest first AC system, with heating and cooling from one quiet indoor head.
Ducted Systems Where They Fit
In a standalone Sunset home with a real attic or crawl space, a ducted central system from AC Installation can work beautifully. But we’ll only route ducts where static pressure stays low; in attached row houses with party walls on both sides, we often recommend against a full ducted retrofit and show you the numbers on why. Your home, your call, but you’ll have the real picture.
Trusted Brands We Service in San Francisco
Meadowsweet Heating & Air is certified to service and install Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For San Francisco’s coastal neighborhoods, we often spec Trane and Daikin, because their factory-coated and corrosion-resistant coil options hold up measurably better in salt air than bare aluminum. We also work on Lennox and Goodman systems, and we keep common parts stocked locally so a repair or replacement in San Francisco doesn’t idle waiting on a freight truck. Visit AC Installation in San Francisco to see how we handle jobs across the city.
Common AC Installation Problems We See in San Francisco Homes
- Corroded condenser coils from marine fog. In the Outer Sunset and Richmond, salt-laden air eats bare aluminum coil fins years before the same unit would fail in the Mission. We recommend factory-coated or corrosion-resistant coils on any outdoor unit west of 19th Avenue.
- Oversized units that short-cycle. A contractor sized by square footage and guessed five tons, so the system kicks on for six minutes, shuts off, and never dehumidifies. Room-by-room load calculations prevent this, and they matter more in San Francisco than almost anywhere else because of the microclimates.
- Failed heat exchangers on floor furnaces. Thousands of pre-1940 Edwardian flats in the Haight, Cole Valley, and Inner Sunset still run on floor furnaces. Once a heat exchanger is condemned, the unit can’t legally be repaired, and replacement often means rerouting heat entirely.
- High static pressure from retrofitted ducts. Forcing a ducted system through a shallow crawl space or around a shared party wall chokes airflow and wears out blower motors early. We check static pressure on every retrofit and won’t install a system that’s going to fight itself.
Pricing for AC Installation in San Francisco, CA
Here’s the honest spread for San Francisco. A ductless mini split installation for one or two rooms often lands near the lower end of the $4,130-$8,850 range.

FAQs About AC Installation in San Francisco
Yes, in most cases. Salt-laden marine fog in the western avenues corrodes standard aluminum condenser coils and cabinet fasteners years faster than inland, and on a fog-belt block of the Outer Sunset we once replaced an outdoor mini split whose coil fins were already crumbling. We spec factory-coated or corrosion-resistant coils from Trane or Daikin for any outdoor unit west of 19th Avenue, and we’ll show you the price difference in writing so you’re not guessing.
Because square footage ignores San Francisco’s microclimates. The Outer Sunset and the Mission can carry cooling loads that differ by whole tons within a mile, especially during late-summer Diablo wind events when offshore air compresses and heats. We run a room-by-room Manual J calculation on every job, using window orientation, insulation, ceiling height, and the actual weather data for your side of the city. An oversized system short-cycles and rots; an undersized one can’t cool. Neither is acceptable.
Yes, a ductless mini split system does exactly that. The indoor head mounts high on a wall or ceiling and connects to an outdoor unit by a small refrigerant line, no ductwork required. For an attached Edwardian with shared party walls and no crawl space access, this is often the only sensible way to get cooling without invasive construction in a historic facade. We’ll tell you if ducted is possible, and if it’s not, we’ll say so plainly.
It shortens it. In the Outer Sunset and Richmond, we recommend an annual coil cleaning and corrosion check every spring, instead of the every-other-year interval that works inland. The salt film builds up, reduces heat transfer, and eats the coil fins from the outside in. A tune-up in San Francisco runs $95-$235, and we’ll photograph what we find so you can see the condition for yourself. Call (747) 966-3037 to book a spring check.
First, look at the outdoor unit’s coil fins for white salt crust or crumbling metal. Second, listen for a system that short-cycles; rapid on-off cycling means it’s oversized or low on refrigerant. Third, change or clean your indoor air filter now, not in July. If anything looks off, don’t open the unit yourself, refrigerant and capacitors carry real danger and a trained professional should handle them. Call us at (747) 966-3037 and we’ll inspect it, give you a written report, and quote any repair before we start.
