Fast, Reliable AC Repair & Installation Across San Francisco
AC repair in San Francisco typically runs $175–$765 and most calls are handled same-day when you reach us by mid-afternoon. We’re Crestview Heating & Air California, and our AC Repair & Installation team makes the trip up from San Jose to serve San Francisco homeowners and commercial properties with the same owner-managed service that earned us 250+ reviews at 4.8 stars. Marcus Feldman, our owner and Service Manager, still carries 19 years of hands-on HVAC experience into the field. San Francisco’s fog-driven micro-climates create unusual cooling demands — the Mission District can hit 95°F in September while Nob Hill stays wrapped in 65°F marine layer the same hour — and that volatility demands technicians who understand how to size and service systems for neighborhood-specific conditions, not just square footage.
Why Crestview Heating & Air California Is San Francisco’s Preferred AC Repair & Installation Company
We’ve built our reputation across the Bay Area by showing up personally and solving problems without passing you through a dispatch center. In San Francisco, that means Marcus Feldman reviews every job himself — from a mini-split retrofit in a 1910 Edwardian flat in the Tenderloin to an emergency compressor replacement in a SoMa loft. 250+ customers who left reviews agree: our 4.8-star average reflects consistent real-world performance, not a handful of curated testimonials.
Our familiarity with San Francisco’s housing stock matters. We’ve worked on gravity wall furnaces in Nob Hill buildings with zero duct infrastructure, routed refrigerant lines through horsehair-plaster walls in Mission District Victorians, and sized equipment for converted warehouse lofts where seismic-bracing requirements under California’s CBC add engineering complexity most inland contractors rarely encounter. Nearly two decades of HVAC experience means we’ve seen virtually every system type, age, and brand a San Francisco property owner could own.
We don’t outsource to subcontractors. Owner-managed, not outsourced — that’s the difference when you’re trusting someone with refrigerant lines inside your walls.
Our AC Repair & Installation Services in San Francisco
AC Repair
San Francisco’s salt-laden fog doesn’t just corrode garage door hardware — it attacks outdoor AC condensers, electrical connections, and capacitor terminals too. We responded to a Mission District home on Valencia Street where the garage door spring snapped on a 95°F day. The original galvanized spring had corroded after only 4 years due to salt air. We replaced it with a stainless steel spring and installed nylon rollers, then added a corrosion inspection to our AC tune-up service. For AC repair specifically, we see capacitor failures accelerated by coastal moisture, compressor electrical damage from salt buildup, and contactor pitting that causes intermittent cooling — all patterns more common in San Francisco’s 94103, 94107, and 94110 ZIPs than in our inland San Jose service area. A typical AC repair in San Francisco runs $175–$765.

AC Installation
Installing central air in San Francisco presents a unique challenge: tens of thousands of Edwardian-era flats across the Tenderloin, Nob Hill, and Mission still rely on original Williams or Empire single-room gravity wall furnaces with no duct connections and no accessible attic space. The most common AC installation we perform in San Francisco isn’t a conventional split system — it’s a ductless mini-split retrofit, routing refrigerant lines through walls built in 1905 with horsehair plaster and balloon-frame construction. AC installation in San Francisco typically costs $4,130–$8,850 depending on head count, electrical upgrades, and whether seismic bracing is required for rooftop or exterior-mounted equipment.

AC Replacement
When an aging system fails in San Francisco, replacement decisions hinge on infrastructure reality. A Victorian flat in Noe Valley with no ductwork and a single wall furnace isn’t a candidate for conventional central air without major architectural intervention. We evaluate whether a multi-zone mini-split, a high-velocity small-duct system, or a hybrid heat pump configuration makes sense given your building’s constraints. Your system, our specialty — we service 9 major brands including Trane, Lennox, Goodman, and Rheem, so we’re not pushing you toward equipment that doesn’t fit your property.

Refrigerant Recharge
Low refrigerant in San Francisco often traces to corrosion at the outdoor unit’s service valves or line-set flare connections — salt air attacks copper and aluminum dissimilar metal junctions. We pressure-test, identify leak points, and recharge with the correct refrigerant type for your system’s age and brand. R-22 systems still operating in older San Francisco buildings require careful handling; we discuss replacement timelines honestly rather than band-aiding obsolete equipment.

Capacitor Replacement
Capacitor failure is one of the most common service calls we get from San Francisco’s 94117, 94118, 94119, and 94120 ZIPs. The combination of coastal humidity and temperature swings from the marine layer stresses start and run capacitors beyond their rated tolerance. We stock replacement capacitors matched to Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard systems, and we check for underlying voltage or connection issues that caused the original to fail prematurely.

Trusted Brands We Service in San Francisco
Your system, our specialty. We maintain factory-trained compatibility across Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so San Francisco customers are never told “we don’t work on that.” For common repairs, we stock capacitors, contactors, and refrigerant fittings matched to Trane, Lennox, Goodman, and Rheem systems locally, which keeps turnaround tight when you’re waiting on cooling during a late-summer heat event in the Mission or Visitacion Valley.
Common AC Repair & Installation Problems We See in San Francisco Homes
- Salt-air corrosion of outdoor electrical components. San Francisco’s Pacific marine layer deposits chloride on capacitor terminals, contactor points, and compressor electrical boxes, causing failures in 3–5 years versus 7–10 years inland. We inspect and treat these connections during every service call.
- Zero-duct infrastructure in pre-1920 buildings. Victorian and Edwardian row houses throughout the 94102–94110 core were built with wall furnaces or radiant heating and no provision for forced-air cooling. Mini-split installation requires creative line-set routing through walls with minimal cavity space.
- Micro-climate mismatch in equipment sizing. A system properly sized for a fog-shrouded Nob Hill flat will be undersized for a south-facing Mission District unit that sees direct sun and 90°F+ heat dome conditions. We perform Manual J load calculations using neighborhood-specific design temperatures, not city-wide averages.
- Seismic-bracing complexity in SoMa lofts and mid-rises. Converted warehouse and concrete buildings in 94103 and 94107 face California CBC and ASCE 7 requirements for rooftop and exterior HVAC equipment that add engineering and installation cost not typically enforced at this level in residential suburbs.

FAQs — AC Repair & Installation in San Francisco
San Francisco’s salt-laden fog accelerates corrosion on both garage-door hardware and outdoor AC components, cutting typical lifespan from 7–10 years inland to 3–5 years coastal. Springs, hinges, rollers, tracks, and opener chains on garage doors fail prematurely; on AC systems, capacitor terminals, contactor points, compressor electrical connections, and line-set flare fittings corrode and leak. We address both with stainless steel and coated replacements plus marine-grade lubrication, and we include corrosion inspection in our AC tune-up service. Call (844) 560-6978 to schedule — estimates are free.
Yes, we replace rusted opener chains with coated chains and lubricate with marine-grade grease rated for salt-air exposure. A rusted chain binds, overloads the motor, and causes premature opener failure — we’ve seen this pattern repeatedly in San Francisco’s outer neighborhoods where fog penetration is heaviest. The repair typically falls within our standard service call range. Call (844) 560-6978 for an exact quote — estimates are free.
Yes, ductless mini-split installation is our most common AC project in San Francisco’s Victorian and Edwardian housing stock. We route refrigerant lines through exterior walls, use slim line-hide channels where aesthetics matter, and place indoor heads to avoid cutting through horsehair plaster unnecessarily. Load calculations account for your specific micro-climate — a south-facing Mission unit needs more capacity than a fog-bound Nob Hill flat of identical size. Call (844) 560-6978 for an exact quote — estimates are free.
We service original Williams and Empire gravity wall furnaces where possible, but replacement parts are increasingly scarce and these units have no efficiency or safety ratings by modern standards. Most of our engagements with 1910s-era wall furnaces in the Tenderloin, Nob Hill, and Mission evolve into system-design conversations about replacing them with ductless heat pumps that provide both heating and cooling. Call (844) 560-6978 for an exact quote — estimates are free.
Salt air is a contributing factor, especially if the outdoor unit sits within a few blocks of the bay or in a fog channel where marine layer lingers. Corroded electrical connections cause voltage drop and hard-start conditions that stress compressor windings; pitting at refrigerant service valves causes leaks that force the compressor to run overheated. We inspect for salt damage, replace compromised components with corrosion-resistant alternatives, and discuss whether a protective coating or more sheltered mounting location would extend replacement compressor life.
