Fast, Reliable Heating & Furnace Across Noe Valley
Heating & Furnace repair in Noe Valley typically costs $175–$825, with most service calls completed same day. Crestview Heating & Air California has been serving Noe Valley’s distinctive Victorian and Edwardian housing stock for nearly two decades, and we understand the unique challenges of working on systems that predate modern HVAC by a century. Call us at (844) 560-6978 for a free estimate.
We’re familiar with the tight crawl spaces under 24th Street flats, the original gravity floor furnaces still embedded in hardwood on Elizabeth Street, and the decorative gas wall heaters that warm the Italianate cottages off Sanchez. Noe Valley’s banana-belt microclimate, sheltered by Twin Peaks from the marine layer, means your heating system works differently here than in fog-soaked Richmond or the Sunset. That local knowledge matters when we’re diagnosing why your 1920s system keeps cycling or why your retrofit mini-split won’t ignite.
Our Heating & Furnace team responds to Noe Valley calls from our San Jose base, and we’ve built our reputation on showing up prepared for the specific quirks of this neighborhood’s aging housing stock.
Why Crestview Heating & Air California Is Noe Valley’s Preferred Heating & Furnace Company
We’ve earned a 4.8-star average across 250+ customer reviews by treating Noe Valley homes with the care they deserve. Owner Marcus Feldman serves as our Service Manager, which means the person accountable for your job is the same person who helped build this company over 19 years. You’re not getting a dispatched contractor who disappears after the invoice clears.
Noe Valley customers tell us they appreciate that we don’t push unnecessary replacements. When we recently serviced a 1910 Edwardian flat on Elizabeth Street where the original in-floor gravity furnace had a cracked heat exchanger, the unit was embedded in old-growth fir flooring with no basement access. We fabricated a custom flush plate and sourced a NOS burner assembly from a specialty supplier in Oakland to avoid destroying the irreplaceable wood floor. That’s the kind of problem-solving 19 years in this trade teaches you.
We carry factory training across nine major brands, including Trane, Lennox, and Rheem, so we rarely need to order parts for a second trip. For Noe Valley’s pre-1920 housing, that speed matters. Your gravity furnace doesn’t have a standard parts catalog anymore.
Our Heating & Furnace Services in Noe Valley
Furnace Repair
Furnace repair in Noe Valley runs $175–$825 depending on the system age and part availability. The most common call we get here isn’t a modern forced-air unit. It’s a cracked heat exchanger in an original in-floor gravity furnace, or a gas valve that’s finally succumbed to decades of sediment buildup in a decorative wall heater. We stock ignitors, gas valves, and burner assemblies for legacy equipment, and we maintain relationships with specialty suppliers who still carry new old stock for systems discontinued before most of us were born.

Furnace Replacement
When repair isn’t economical, we guide Noe Valley homeowners through replacement options that respect their building’s constraints. Most Noe Valley flats have zero ductwork and balloon-frame construction with tight joist bays. Forced-air retrofits often aren’t feasible without major structural work. We frequently recommend ductless mini-splits for Noe Valley’s Edwardian flats, especially given the banana-belt warmth that creates real summer cooling demand a few blocks away in the Mission wouldn’t feel. We’ll walk you through the cost comparison: a new high-efficiency wall heater versus a multi-zone mini-split system, including electrical upgrades if your flat still has active knob-and-tube wiring.

Furnace Tune-Up
A furnace tune-up in Noe Valley costs $95–$235 and should happen annually before the heating season. For gravity floor furnaces and decorative wall heaters, our tune-up includes combustion analysis, gas pressure verification, and inspection of the heat exchanger for cracks that could vent carbon monoxide into living spaces. We also check for proper venting through original masonry chimneys, which in Noe Valley’s older buildings can suffer from deteriorated mortar or bird nesting. Lower humidity here than on the foggy west side means less corrosion, but it also means dust accumulates faster. We clean burner orifices and pilot assemblies that haven’t been touched in years.

Heat Exchanger Inspection & Replacement
Cracked heat exchangers are the most serious safety issue we find in Noe Valley’s original heating equipment. A cracked exchanger can leak carbon monoxide directly into your home, and in a gravity furnace embedded in your floor, there’s no room for error. We use borescope cameras to inspect exchangers without destructive disassembly, and when replacement is possible, we fabricate custom mounting solutions for the non-standard dimensions of pre-1920 units. Sometimes the exchanger itself can be welded or patched by a specialty metal shop we partner with in the East Bay. When it can’t, we’ll tell you honestly and help you plan a safe replacement strategy.

Ignitor Replacement
Ignitor replacement in Noe Valley costs $150–$700. We see two distinct failure patterns here. In original gas wall heaters and gravity furnaces, ignitor failures usually mean a standing pilot that’s been extinguished by downdraft in original venting or a thermocouple that’s finally worn out after 40+ years. In retrofitted ductless mini-splits, ignitor failures are increasingly caused by power surges from aging knob-and-tube wiring still present in some pre-1920 flats. The surge fries the electronic ignition module. We stock both standing-pilot thermocouples and electronic ignitors, and we’ll assess your electrical system to prevent repeat failures.

Gas Valve Repair
Gas valves in Noe Valley’s legacy decorative wall heaters often fail after decades of sediment accumulation from San Francisco’s gas supply. The valve won’t open fully, or it won’t close completely, creating a dangerous slow leak or inefficient burn. Direct replacements haven’t been manufactured for many of these valves, so we either rebuild the existing valve with new seals and diaphragms, or we adapt a modern valve to work with the original manifold configuration. Either approach requires field fabrication and careful leak testing. We don’t guess with gas.

Trusted Brands We Service in Noe Valley
We service equipment from nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Noe Valley’s newer retrofits and additions, we commonly work on Trane and Lennox ductless systems, and we stock Rheem parts for the wall heaters that replaced original gravity furnaces in the 1960s and 70s. Our factory training means we don’t decline jobs because of brand. Your system, our specialty. We also maintain a running inventory of universal and legacy parts at our San Jose warehouse, so most Noe Valley service calls don’t wait on shipping.
Common Heating & Furnace Problems We See in Noe Valley Homes
- Cracked heat exchangers in original in-floor gravity furnaces. The constant heating and cooling cycle of cast-iron or steel exchangers over 80+ years eventually causes metal fatigue. In Noe Valley, we find these embedded in old-growth fir flooring with no basement access below, making replacement a custom fabrication job rather than a parts swap.
- Gas valve failure in legacy decorative wall heaters. Decades of sediment in the gas line slowly degrade valve seals. Many of these valves were made by manufacturers that no longer exist, so we rebuild or adapt rather than replace with off-the-shelf parts.
- Ignitor failure in retrofitted ductless mini-splits caused by power surges. Aging knob-and-tube wiring in pre-1920 Noe Valley flats creates voltage irregularities that fry electronic ignition modules. The fix isn’t just a new ignitor. It’s assessing whether your electrical system needs upgrading.
- Inefficient or uneven heating due to original gravity system design. Gravity floor furnaces rely on natural convection, which means the warmest room is directly above the unit and bedrooms down the hall stay cold. We help Noe Valley homeowners understand when zoning improvements or supplemental heating makes more sense than fighting physics.

FAQs — Heating & Furnace in Noe Valley
Yes, we regularly repair original in-floor gravity furnaces in Noe Valley without destroying irreplaceable old-growth fir flooring. We fabricate custom flush plates to match existing cutouts and source new old stock parts from specialty suppliers when standard replacements don’t exist. Call (844) 560-6978 for a free assessment of your specific unit.
Repeated ignitor failure in Noe Valley mini-splits is most often caused by power surges from aging knob-and-tube wiring still present in many pre-1920 flats. The surge damages the electronic ignition module. We replace the ignitor and evaluate whether your electrical system needs upgrading to prevent repeat failures. Call (844) 560-6978 to schedule diagnostics.
The answer depends on your heating and cooling needs, your building’s electrical capacity, and your budget. New high-efficiency wall heaters cost less upfront but provide only heat. Ductless mini-splits handle both heating and cooling, which matters in Noe Valley’s warmer banana-belt microclimate, but may require electrical upgrades in older flats. We provide honest comparisons based on your specific building. Call (844) 560-6978 for a free estimate.
Schedule a furnace tune-up annually, ideally in early fall before the heating season begins. Noe Valley’s lower humidity and reduced marine fog compared to western San Francisco means less moisture-related corrosion, but dust accumulation is still significant. Annual maintenance catches cracked heat exchangers, venting problems, and combustion issues before they become safety hazards. Call (844) 560-6978 to book your tune-up.
