Carrier HVAC in San Francisco, CA | Crestview Heating & Air California
We provide independent Carrier service across San Francisco’s fog belts and heat pockets, with 19 years of hands-on experience fixing Infinity heat pumps in Mission District Carrier service Victorians and installing 38MGR ductless systems in Edwardian flats that never had ductwork. The one thing that makes our Carrier work here different: we size equipment neighborhood by neighborhood, because a load calculation for a fogged-in Richmond District row house fails completely three miles east in SoMa during a heat dome. Call (844) 560-6978 for a free estimate on any Carrier system.
Why San Francisco Residents Choose Us for Carrier Service
We’ve been inside enough San Francisco homes to know that “Carrier repair” means something different here than in Sacramento or San Jose. Marcus Feldman, our owner and Service Manager, grew up in Woodland Hills where summer heat was relentless — he learned early that a broken system isn’t an abstract problem, it’s a week of misery. That mindset carried through his training at Los Angeles Trade-Technical College and into the 19 years since he launched Crestview Heating & Air. He still runs service calls himself.
Our Carrier sales & service covers the full product line, from Infinity variable-speed heat pumps to Comfort 80 gas furnaces. We’re factory-trained compatible across nine major brands, but Carrier’s ductless mini-splits dominate our San Francisco workload for a reason: most buildings in 94117, 94118, 94119, and 94120 were built before 1925 with balloon-frame construction, no duct chases, and horsehair-plaster walls. You can’t just drop in a standard split system. We stock OEM Carrier compressors, control boards, and coils locally because San Francisco’s salt-laden marine air chews through aftermarket alternatives faster than inland climates allow. Our 4.8-star average across 250+ reviews? Those customers left them after we solved problems other companies walked away from.
Common Carrier HVAC Problems We Solve in San Francisco
- Condenser coil corrosion in western neighborhoods. The Pacific marine layer rolling through the Sunset and Richmond Districts carries salt that pinholes Carrier aluminum coils within 5–7 years. We’ve replaced Infinity 19VS outdoor units where the coil looked like Swiss cheese — always with OEM copper-tubed replacements, never generic aluminum, because the fog doesn’t stop.
- Compressor burnout from undersized returns in Victorian flats. Carrier Performance 14 SEER systems installed in 1890s Nob Hill buildings often fight against original 6-inch wall cavities used as return plenums. Chronic high head pressure cooks the compressor. We measure static pressure before quoting any repair, because replacing a compressor without fixing the return path is throwing money into the bay.
- Evaporator freeze-ups in Tenderloin ductless retrofits. Carrier 38MGR mini-splits installed in flats with original Williams gravity furnaces have no backup heat source. When fog keeps temperatures in the low 60s for weeks, the mini-split runs continuously and ices the coil. We diagnose these as control-strategy problems, not refrigerant leaks — and we fix the controls.
- Reversing valve failures during Mission heat domes. Carrier heat pumps in 94110 short-cycle violently when temperatures swing 30°F in a single afternoon, which happens here and almost nowhere else. The reversing valve sticks between heating and cooling modes. We’ve learned to spec heavier-duty valves for Mission installations after seeing three failures in one July.
- Pilot outages in Richmond District Comfort 80 furnaces. Older Carrier gas furnaces near Ocean Beach fight against downdrafts through century-old chimneys. The thermocouple tests fine in our shop and fails the next foggy night. We check chimney draw with a manometer, not just a match, because “working when we left” isn’t good enough.
Carrier Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s Building Code contains a clause that most homeowners never hear about until they’re staring at a bid $600 higher than expected: any new HVAC installation within 100 feet of the liquefaction zone — which covers most of SoMa and the Marina — requires seismic bracing for the condenser pad and a gas shutoff valve strapped to the structure. This isn’t a contractor upsell. It’s SFBC enforcement of CBC and ASCE 7 requirements, and it adds $400–$800 to every Carrier job in those areas. We’ve done Carrier 38MGR multi-zone installs in SoMa concrete lofts where the structural engineer’s bracing spec cost more than the mini-split heads. For Carrier owners in Nob Hill or the Tenderloin, outside the liquefaction zone, that line item disappears. But the horsehair-plaster walls and zero attic clearance don’t — they just trade one San Francisco problem for another. This is why we don’t quote Carrier installations over the phone. We look at the building, the neighborhood, and the specific micro-climate stress your equipment will face.
Carrier Models & Products We Service in San Francisco
We work on every Carrier line you’re likely to find in San Francisco residential or small commercial buildings:
- Carrier Infinity 19VS — variable-speed heat pump, increasingly common in Mission and Noe Valley retrofits where cooling demand spiked after 2019 heat domes
- Carrier Performance 14 SEER — single-stage AC, often the only cooling in pre-war buildings where a condenser was squeezed onto a rear deck
- Carrier Comfort 80 — gas furnace, still running in thousands of Richmond and Sunset District homes, usually paired with original wall furnaces in other rooms
- Carrier 38MGR — multi-zone ductless outdoor unit, our most frequent San Francisco install because it solves the no-ductwork problem without gutting historic interiors
We carry OEM Carrier compressors, fan motors, control boards, and coils in our local inventory. For capacitors and contactors, we’ll use quality aftermarket like Supco if OEM is backordered — but we tell you before we install, and we warranty the work either way. “If I wouldn’t put it in my own house, I’m not putting it in yours.” That’s how Marcus runs it.
Carrier Service Pricing in San Francisco
| Service | Price Range |
|---|---|
| AC Repair | $175–$765 |
| Furnace Repair | $175–$825 |
| AC Installation | $4,130–$8,850 |
| Tune-Up | $95–$235 |
What drives the cost? For repairs, it’s parts availability and access — a control board behind a built-in cabinet in a Pacific Heights flat takes longer than the same board in an open garage. For installs, it’s the seismic bracing requirement in SoMa, the custom line-set routing in Victorians, and whether we’re doing a single-zone mini-split or a full multi-zone 38MGR system. Every estimate we provide is free and itemized. Call (844) 560-6978 for yours — we’ll look at your specific building, not just your ZIP code.

FAQs — Carrier HVAC in San Francisco
Yes, we do this regularly. In a 1910 Edwardian on Jones Street last year, we routed a 38MGR line-set through a custom chase behind a false beam to preserve original crown molding. We never cut plaster speculatively — we map the wall cavity first. Call (844) 560-6978 and we’ll walk through your specific layout.
Probably not oversized — more likely it’s responding to rapid temperature swings that are unique to San Francisco’s micro-climates. Chinatown Carrier service areas and Mission heat domes can push past 95°F while the waterfront stays fogged in, and your Infinity’s variable-speed compressor may be hunting between stages. We check load calculations against actual neighborhood temperature data, not citywide averages. Call (844) 560-6978 for a diagnostic.
Yes. San Francisco requires permits for all furnace replacements, and if you’re in the liquefaction zone (most of SoMa, parts of the Marina), you’ll also need seismic bracing inspection. We pull permits as part of our standard process — it’s not an add-on, and we handle the scheduling. Call (844) 560-6978 to confirm what’s required for your address.
Most likely. SoMa’s concrete mid-rise conversions often drain mini-split condensate through a pump rather than gravity, and those pumps fail every 3–5 years in continuous-use installations. We stock replacement pumps and can usually swap one same-day. Call (844) 560-6978 — we’ll confirm with a quick diagnostic visit, estimates are free.
Sometimes. If it’s a failed thermocouple and your chimney draws properly, a repair runs $175–$350. But if the heat exchanger is cracked or the downdraft problem is structural, replacement is safer. Richmond District homes near Ocean Beach face unique venting challenges from marine-layer pressure changes. We’ll test both and give you honest numbers. Call (844) 560-6978 for a free evaluation.
Service Areas Near San Francisco
