Fast, Reliable Heating & Furnace Across Noe Valley
Heating and furnace repair in Noe Valley runs $175–$825 for most repairs, with furnace replacement typically falling between $3,500–$7,500 depending on your home’s existing infrastructure. We handle everything from corroded floor furnaces in 1890s Victorians to modern high-efficiency retrofits, and we know the specific permit and corrosion challenges that come with working in this neighborhood.
We’ve been driving our trucks up and down the hills of Noe Valley for nearly two decades. Anthony Moreno, our founder and lead installer, still shows up on the job personally, whether it’s an emergency call on 24th Street or a planned replacement in the flats near Dolores Park. Noe Valley’s unique microclimate, that sheltered warmth that sits 5–10°F above what the Inner Sunset sees on the same afternoon, means your heating system works differently here than just about anywhere else in San Francisco. That matters when we’re sizing equipment, diagnosing failures, or explaining why your 1920s flat needs a different approach than a new build in Daly City. If your furnace is blowing cold air, cycling constantly, or you smell gas near your floor furnace, call us at (877) 454-5066. We offer free estimates and emergency service for urgent situations.
Why Meridian Heating & Air Los Angeles Is Noe Valley’s Preferred Heating & Furnace Company
Our reputation in Noe Valley was built one job at a time, not through marketing campaigns. We’ve worked in the Victorian and Edwardian row houses that dominate this neighborhood, from the plaster-walled flats near Castro Street to the hillside homes with balloon framing on the slopes toward Diamond Heights. That familiarity matters. We don’t waste your time figuring out how to run line sets through lath walls or where the original floor furnace sits beneath hundred-year-old hardwood.
286 customers and counting have left us reviews averaging 4.8 out of 5 stars. Those aren’t numbers from a single good month; they represent nearly two decades of showing up, doing the work, and standing behind it. Anthony Moreno personally leads installations and service calls, so the expertise you read about is the same expertise that walks through your door.

Our Heating & Furnace Services in Noe Valley
Furnace Repair
Furnace repair in Noe Valley typically costs $150–$700, with most calls landing in the $250–$450 range depending on parts and accessibility. The most common repair we see here isn’t the failed blower motor or cracked ignitor you’d expect inland. It’s heat exchanger corrosion in original floor furnaces, accelerated by decades of salt-air exposure creeping through crawl spaces and foundation vents. We retrofitted a ductless mini-split heat pump into a 1905 Victorian flat on 24th Street, replacing a corroded floor furnace that had rusted through its heat exchanger from decades of salt-air exposure. Our crew ran the line sets through plaster-and-lath walls and got the permit sealed within the week. If your floor furnace is putting out soot, making unusual rumbling sounds, or triggering your CO detector, that’s not a maintenance item. It’s a safety issue that needs immediate professional attention.
Furnace Replacement
A full furnace replacement in Noe Valley runs $3,500–$7,500, with the wide range reflecting whether we’re swapping a like-for-like wall heater or engineering a completely new heating solution for a ductless Victorian flat. Many Noe Valley homes were built between 1890 and 1925 with absolutely no ductwork pathways, so a conventional forced-air retrofit means cutting through plaster-over-lath walls and running duct chases that eat square footage you don’t have. We often recommend ductless mini-split heat pumps or high-velocity systems for these properties. Anthony evaluates each home personally, because the “right” replacement in Noe Valley depends on your building’s framing, your electrical service, and whether SF’s Department of Building Inspection will approve the installation path. Permits for furnace replacement in Noe Valley are mandatory, and DBI review adds lead time that surprises homeowners who’ve moved from less regulated markets.
Furnace Tune-Up
Annual furnace tune-ups in Noe Valley cost $80–$200, and they’re particularly valuable here because of how intermittently these systems run. Noe Valley’s mild winters mean your floor furnace or wall heater might only fire a few dozen times per season, and intermittent use causes its own problems. Gas valves gum up. Ignitors carbon over. Heat exchangers develop condensation corrosion from short cycling rather than steady operation. Our tune-up includes combustion analysis, gas pressure verification, heat exchanger inspection with a borescope, and a written condition report. For homes in the 94131 ZIP code with original equipment, we also inspect for salt-air corrosion on burner assemblies and pilot tubing. Catching a cracked heat exchanger during a tune-up beats finding out about it when your CO alarm goes off at 2 a.m.
Heat Exchanger Inspection & Replacement
Heat exchanger failure is the repair that ends the conversation about “fixing” an old furnace in Noe Valley. In coastal neighborhoods like this, we’ve seen heat exchangers fail in as little as 12–15 years on floor furnaces that should last 20+. The salt air doesn’t just rust the exterior cabinet; it accelerates internal corrosion where combustion gases meet condensate. A cracked heat exchanger means carbon monoxide can mix with your indoor air, and in Noe Valley’s tightly sealed Victorian flats with original windows painted shut, there’s nowhere for that gas to go. We inspect with fiber-optic cameras, and if we find cracks or thinning, we recommend replacement. Sometimes that’s a new heat exchanger. Often, given the age of Noe Valley’s housing stock, it’s a full system replacement with modern safety controls.

Trusted Brands We Service in Noe Valley
We work on your brand. Our technicians are factory-trained or field-experienced on nine major HVAC manufacturers, and for Noe Valley customers we regularly stock parts and complete systems from Trane, Lennox, Goodman, and Rheem. Trane’s coated heat exchangers hold up well against salt-air corrosion. Lennox’s variable-speed systems pair nicely with the ductless retrofits common in Noe Valley’s older housing stock. Goodman offers solid value for straightforward replacements in homes that already have ductwork, and Rheem’s modulating furnaces handle the mild-load conditions we see here better than single-stage units that short-cycle all winter. Because Anthony still leads installs personally, we don’t push whatever’s in the warehouse. We recommend what fits your home, your microclimate, and your budget.
Common Heating & Furnace Problems We See in Noe Valley Homes
- Floor furnace heat exchangers rust out prematurely from coastal salt air. These units sit in crawl spaces or basement cavities where marine air circulates freely, and the combination of moisture and salt accelerates metal fatigue. We find pinholes and cracks that create CO leakage risks, especially dangerous in Noe Valley’s sealed Victorian flats with minimal ventilation.
- Original gas wall heaters clog with debris and fail ignitors after years of intermittent use. Noe Valley’s mild winters mean these units fire less frequently than in colder climates, but each startup cycle deposits carbon and draws dust into burner orifices. The result is hard starting, rollout, or complete ignition failure when you finally need heat.
- Old cast-iron radiators develop pinhole leaks from internal corrosion. The mineral-rich Hetch Hetchy water used in San Francisco’s steam systems leaves scale and accelerates metal thinning. We’ve replaced radiators in Noe Valley homes where the leak started as a weep and became a gusher mid-winter.
- Non-standard window configurations make portable heating solutions impractical. Original double-hung sash windows in Victorian flats are often painted shut or built to widths that don’t accommodate modern window units. This pushes Noe Valley homeowners toward permanent heating solutions sooner than they might prefer.

What moves you toward the high end? Accessibility is the big one. A floor furnace in a cramped crawl space on a hillside property takes longer to reach and repair than a wall heater at chest height. Permits add cost too, SF’s DBI requires them for most furnace replacements and any exterior penetration for mini-split line sets. Material choices matter: a stainless heat exchanger or coated burner assembly costs more upfront but pays back in lifespan against Noe Valley’s salt air. We discuss all of this before any work begins. Estimates are free, and Anthony personally reviews every replacement quote to make sure we’re not spec’ing more equipment than your home needs. Call (877) 454-5066 to schedule yours.

FAQs — Heating & Furnace in Noe Valley
Floor furnaces in Noe Valley fail faster because salt-laden marine air circulates through crawl spaces and foundation vents, accelerating rust on heat exchangers and burner assemblies. The neighborhood’s sheltered bowl doesn’t block this corrosion, it just blocks the cooling fog, so you get warm days and corrosive nights. If your floor furnace is over 15 years old, we recommend annual inspection with borescope verification of the heat exchanger. Call (877) 454-5066 to schedule, estimates are free.
Yes, but not a conventional forced-air furnace. Noe Valley’s Victorian and Edwardian flats built between 1890 and 1925 have no designed ductwork pathways, and retrofitting ducts means cutting through plaster-over-lath walls with minimal cavity access. We typically recommend ductless mini-split heat pumps or high-velocity small-duct systems that don’t require major structural modification. Anthony evaluates each home personally to determine the cleanest installation path and what SF DBI will permit. Call for a free assessment.
Noe Valley’s microclimate runs 5–10°F warmer than nearby neighborhoods, which reduces heating load but increases cooling demand, a combination that surprises many homeowners. We size heating equipment using actual Manual J load calculations rather than rules of thumb, because an oversized furnace in a mild-climate Victorian flat will short-cycle, waste fuel, and fail prematurely. Our calculations account for your specific block’s exposure, not just ZIP-code averages.
Yes. San Francisco’s Department of Building Inspection requires permits for furnace replacement and any exterior wall penetration for line sets or venting. For Noe Valley’s older buildings, DBI may also require structural review if the installation involves new openings in plaster-over-lath walls. We handle permit submission and inspection scheduling as part of our replacement service, and we factor the lead time into our project planning so you’re not left without heat unexpectedly.
We recommend Trane and Rheem for their coated heat exchangers and corrosion-resistant burner assemblies, and Lennox for their variable-speed systems that pair well with ductless retrofits. Goodman offers strong value for simpler replacements. Every recommendation depends on your home’s existing infrastructure and your heating load, not just brand preference. We work on all nine major brands we service, so our advice isn’t limited to one product line. Call (877) 454-5066 to discuss what fits your specific situation.
