AfterFast, Reliable AC Repair Across San Francisco
AC repair in San Francisco typically costs $175 – $765 for most diagnostic and common part replacement jobs, and our AC Repair team can usually reach San Francisco homes the same day you call. We’re based right here in the Bay Area, with dispatch coordinated from our local San Francisco metro office and crews who know the city’s hills, microclimates, and housing stock from the Outer Sunset to Potrero Hill.
San Francisco’s homes are different. Most were built before central air existed. When your AC stops blowing cold air, you need a technician who understands why a standard fix might not work in a 1905 Edwardian with no ductwork or a Victorian that just had seismic retrofit work block the crawl space. That’s the work we do. Call (984) 538-9003 and a live person will answer, 24 hours a day.

Devin Marlowe leads our operation here, and that local accountability matters when you’re letting someone into your home.
Our Threshold Verified standard means you know exactly who is coming before they arrive. We send you the technician’s name and photo, and they show a photo ID badge at your door. If anyone shows up who you weren’t told to expect, that visit is on us. For homeowners in San Francisco who live alone, have young children, or simply want certainty about who is walking through their door, this isn’t extra. It’s the baseline.

AC Not Blowing Cold Air in San Francisco
AC Not Blowing Cold Air in San Francisco is almost never a simple “low on Freon” fix, because most systems here are first-time ductless mini splits or heat pumps installed into homes that never had AC before, and the marine layer brings salt-air corrosion that mimics other failures.
A typical call starts at $175 for diagnostic, with most completed repairs landing between $175 and $765 depending on what we find. The real challenge is figuring out whether you’re dealing with a failed capacitor, a refrigerant leak from corroded coils, or a system that was never properly sized for your home’s layout in the first place.
Refrigerant Recharge and Leak Detection
When we find low refrigerant, we don’t just top it off. We pressure-test the system to locate the leak, because in San Francisco’s fog belt, salt air eats condenser coils and cabinet fins years faster than inland. A recharge without fixing the leak means you’ll call us again in six months.
Capacitor and Compressor Issues
Capacitors fail from heat cycling and age. Compressors fail from running low on refrigerant or from short-cycling in an oversized single-zone system. We test both, explain what we found, and give you a written price before replacing anything.
AC Service in San Francisco
AC Service in San Francisco means something different than in Phoenix or Houston. Most of our service calls aren’t tune-ups on decades-old central systems. They’re maintenance visits on relatively new ductless mini splits and heat pumps that were shoehorned into Victorians and Edwardians with no existing infrastructure.
A standard AC Service / Tune-Up runs $95 – $235. We clean coils, check refrigerant levels, test electrical components, and verify that your system is actually matched to your home’s load. In San Francisco, that last part catches a lot of problems that other companies miss.
Load Verification and System Balancing
Many San Francisco homes got a single-zone mini split installed without a proper load calculation. The system cools the downstairs fine but can’t reach upstairs bedrooms, or it short-cycles because it’s oversized for a fog-cooled Outer Sunset living room. During service, we measure actual performance against what your home needs.
Salt-Air Corrosion Inspection
For homes in the Richmond, Outer Sunset, or any block within a few miles of the ocean, we inspect condenser coils and cabinet condition. Catching corrosion early can save you from a $765 repair or premature replacement.
Trusted Brands We Service in San Francisco
We service all major residential HVAC brands, including Trane, Lennox, Goodman, and Rheem. Our San Francisco Bay Area office stocks common capacitors, contactors, and refrigerant fittings locally, which means faster turnaround on repairs. We also work on Daikin, Carrier, Bryant, York, and American Standard systems. Because many San Francisco homes run newer ductless equipment that was installed as a first-time system, we keep up with inverter-driven compressor technology and the specific fault codes these units throw when something goes wrong.
Common AC Repair Problems We See in San Francisco Homes
- Single-zone mini splits short-cycling in multi-story Victorians. A one-head system in a two-story Edwardian on a Haight-Ashbury block was never going to reach the upper bedrooms. We see this constantly. The fix is either additional heads or a properly zoned system, not another repair on the undersized unit.
- Salt-air corrosion causing refrigerant leaks in fog-belt neighborhoods. Condenser coils in the Outer Sunset and Richmond deteriorate from marine exposure. The leak mimics a simple “needs Freon” call, but the real problem is a compromised coil that needs replacement or protective treatment.
- Soft-story retrofit work blocking lineset paths. Pre-1978 buildings that underwent mandated seismic retrofitting often have new structural elements in crawl spaces and garage ceilings exactly where mini split linesets and condensers need to run. A like-for-like equipment swap can stall at permit when the original path no longer exists.
- Gravity floor furnace intersections. In the Inner Richmond and Haight-Ashbury, we still find old gravity floor furnaces sharing space with newer AC attempts. Decommissioning or working around these requires navigating San Francisco’s DBI permit process and the physical reality of a subfloor that predates modern equipment by a century.
Pricing for AC Repair in San Francisco, CA
| Service | Typical Range |
|---|---|
| AC Repair (diagnostic + common part replacement) | $175 – $765 |
| AC Service / Tune-Up | $95 – $235 |
| Furnace Repair (when gravity furnace tied into same call) | $175 – $825 |
What moves you up or down within these ranges? Three things: the part that’s failed, whether we need to recover and recharge refrigerant, and how accessible your equipment is. A capacitor swap on a ground-level condenser in Noe Valley is straightforward. A refrigerant leak hunt on a corroded coil in a wind-exposed Outer Sunset backyard takes longer. We give you a written price before any work starts, always, with no exceptions. Estimates are free. Call (984) 538-9003.

FAQs About AC Repair in San Francisco
Most ductless mini splits have a minimum operating temperature, and some budget models won’t run the cooling cycle below 60 – 65°F ambient. In San Francisco’s fog belt, that’s a real problem. We can recalibrate the unit’s settings or recommend a cold-climate heat pump model designed for our conditions. Call (984) 538-9003 and we’ll check what’s installed.
Yes. We work on homes with gravity floor furnaces regularly in the Haight-Ashbury and Inner Richmond. The AC side is almost certainly a ductless mini split that was added later. We repair those systems all the time. If you’re looking to replace the gravity furnace too, that involves San Francisco’s DBI permit process and careful structural assessment, but it’s absolutely doable.
Your single-zone system was probably never sized with a proper load calculation for a multi-story Victorian or Edwardian floor plan. Heat rises. One head downstairs can’t overcome that physics. We’ve rebalanced and added heads to dozens of these setups across San Francisco. A quick load calculation tells us whether your system is salvageable or needs expansion.
Seismic retrofit work often installs new structural elements or shear walls exactly where linesets ran or where a condenser was mounted. For a simple repair, we work around it. For a replacement, we may need to reroute linesets or relocate the condenser, which triggers permit and inspection requirements with San Francisco’s DBI. We handle that paperwork.
Given California’s electrification push and San Francisco’s mild climate, a heat pump often makes more sense than repairing an aging AC-only system, especially if your heating is still gas. Heat pumps handle both heating and cooling efficiently in our temperature range, and rebates may apply. We’ll give you honest numbers on repair versus replacement so you can decide. Call (984) 538-9003 for a free estimate.
