We’ve been crawling the tight basements and subfloor cavities of Mission District flats for a decade. Daniel Okafor, our owner and lead technician, knows the difference between a 1905 Edwardian on Valencia with original lathe-and-plaster walls and a 1960s stucco duplex off Cesar Chavez, because he’s personally worked on both. That matters when you’re trying to run a new vent pipe through a shared party wall or replace a floor furnace in a building where the crawlspace is 14 inches high. Mission District’s 94110 zip code is our regular territory, not an afterthought.
Why Northstar Heating & Air San Francisco Is Mission District’s Preferred Heating & Furnace Company
357 customers agree: our 4.9-star average comes from showing up, diagnosing honestly, and fixing it right the first time. No dispatcher filtering your call, no rotating crew of strangers. Daniel personally handles every heating call in Mission District, which means the same person who quotes your furnace replacement is the one who installs it.
Response time to Mission District averages under 90 minutes for emergency heating calls. We know the parking realities on 24th Street during evening rush, the one-way patterns around Dolores Park, and which Mission alleys accommodate a service van. That local fluency saves 10-15 minutes on every call, which matters when your heat is out and the temperature’s dropping.
A decade of doing this right in San Francisco means we’ve replaced floor furnaces on Shotwell, repaired Bryant units in converted Victorians near Mission Dolores, and tuned up York systems in live-work lofts along Harrison. That accumulated neighborhood knowledge is what lets us quote accurately and show up with the right parts.
Our Heating & Furnace Services in Mission District
Furnace Repair
Furnace repair in Mission District homes often involves gravity furnaces, wall heaters, or compact forced-air units squeezed into spaces never designed for them. We see cracked heat exchangers in aging floor furnaces on Capp Street, failed ignitors in post-war duplexes near Precita Park, and gas valve issues in converted commercial kitchens along Mission Street. Our Heating & Furnace team carries replacement parts for York, Bryant, and American Standard units, plus universal-fit components for the orphaned brands common in these older buildings. Most repairs finish same day.

Furnace Replacement
Replacing a furnace in Mission District presents unique constraints: minimal attic clearance, no existing ductwork in many flats, and shared walls that limit venting options. We’ve retrofitted high-efficiency American Standard units into 1890s Victorians near Dolores, installed compact Bryant systems in basement mechanical closets on Alabama Street, and converted floor furnace setups to wall-mounted condensing units where crawlspace access made traditional replacement impossible. For cooling, we also offer our AC Repair & Installation in Mission District. Every Mission District replacement starts with a load calculation that accounts for the neighborhood’s warmer microclimate and those shared party walls.

Furnace Tune-Up
A furnace tune-up in Mission District runs $95–$235 and typically takes 60-90 minutes. We focus on combustion analysis, gas pressure verification, and heat exchanger inspection, because many units here run in tight enclosures with limited ventilation. For the original floor furnaces still operating on Harrison and in the Mission Dolores area, our tune-up includes burner orifice cleaning, thermocouple testing, and carbon monoxide checks around the floor grate perimeter. Annual tune-ups prevent the mid-winter failures that are especially disruptive in buildings where tenants share one heat source.

Heat Exchanger Repair & Replacement
Cracked heat exchangers are a serious safety issue we encounter regularly in Mission District’s aging furnace stock. The cast-iron heat exchangers in 1940s-1960s floor furnaces develop stress fractures after decades of thermal cycling, and the tubular steel exchangers in early forced-air units corrode from the inside out. We do not patch heat exchangers, we replace them, because anything less is a carbon monoxide risk. In Mission District buildings where the original furnace is too deteriorated for exchanger replacement alone, we’ll walk you through the retrofit options honestly, including whether a Heat Pump & Mini Split in Mission District makes more sense given your building’s constraints.

Common Heating & Furnace Problems We See in Mission District Homes
- Red-tagged floor furnaces after permit pulls. San Francisco’s Department of Building Inspection increasingly flags original in-floor gravity furnaces during sale or renovation permits, especially in the Mission’s pre-1960s housing stock. We specialize in retrofitting compliant replacement heat sources into buildings with zero duct infrastructure and tenants still in place.
- Failed ignitors in high-humidity basements. Mission District’s older flats often have partial basements with moisture issues from aging foundations and poor drainage. That humidity corrodes hot surface ignitors and damages flame sensors, causing intermittent or no-heat calls that spike during the first cold snap.
- Heat exchanger cracks in original wall heaters. The single-zone wall heaters common in Mission District’s two-unit Victorians were designed for 20-year lifespans and are now pushing 40-60 years. We find cracked exchangers and deteriorated vent connectors during routine service calls on Shotwell, Capp, and in the Mission Dolores area.
- Uneven heating in converted flats with added walls. As Mission District’s housing stock has been subdivided and reconfigured, original single-zone heating systems now serve chopped-up floor plans. We see cold bedrooms, overheated common areas, and thermostats located in the one warm corner of the building.
