Fast, Reliable Heating & Furnace Across San Anselmo
San Anselmo’s inland Ross Valley location means your furnace works harder than you might expect. While coastal Marin stays mild, our valley traps heat in summer and lets winter cold settle in hard — yet most homes along San Anselmo Avenue and in the Sleepy Hollow neighborhood were built before 1950 with gravity floor furnaces or decorative fireplaces as the only heat source. If your Craftsman bungalow on Crescent Road is running a decades-old system, or your hillside ranch off Sir Francis Drake Boulevard is struggling through another January cold snap, we can get there quickly. Call (877) 454-5066 for a free estimate.
We’ve been handling Heating & Furnace work long enough to know that San Anselmo’s housing stock creates specific challenges. Tight crawl spaces under pier-and-beam foundations, original knob-and-tube wiring still live in some walls, and the town’s aggressive reach codes pushing toward all-electric retrofits — these aren’t obstacles you figure out on the fly. Anthony Moreno, our founder and lead installer, has spent nearly two decades solving exactly these problems in older California homes.
Why Meridian Heating & Air Los Angeles Is San Anselmo’s Preferred Heating & Furnace Company
Our reputation in San Anselmo was built one job at a time. 286 customers and counting have left reviews averaging 4.8 stars, and a significant share come from repeat calls in the 94960 ZIP — particularly from homeowners in the flood-prone creek-adjacent blocks who remember which contractors showed up after the 2005 inundation and which didn’t.
Anthony shows up on the job. Not a rotating subcontractor, not a dispatcher sending whoever’s available. When you schedule a furnace replacement on Elm Avenue or a heat exchanger inspection near Memorial Park, you’re getting 19 years of hands-on HVAC experience from someone who still carries tools and climbs into crawl spaces.
Response time to San Anselmo matters when your furnace fails on a 38°F January morning. We keep common Rheem and Goodman parts stocked for faster turnaround, and our familiarity with Marin County’s permit requirements — especially the all-electric provisions in newer reach codes — means we don’t waste your time figuring out local compliance on the clock.
Our Heating & Furnace Services in San Anselmo
Furnace Repair
A typical furnace repair in San Anselmo runs $175–$825, with most calls landing in the $240–$450 range depending on parts. The town’s pre-war housing stock means we regularly encounter original gravity furnaces still limping along in homes off Center Boulevard, plus 1980s-era gas units in the upper hillside ranches that are hitting end-of-life all at once. We work on your brand — Goodman, Rheem, York, Daikin, and five others — so the right fix isn’t limited to whatever one manufacturer sells.
Furnace Replacement
Full furnace replacement in San Anselmo demands more than swapping boxes. The majority of homes in the 94960 ZIP were built without ductwork, and many crawl spaces along San Anselmo Creek have flooded at least once since 2005. Anthony Moreno personally assesses whether your existing mechanical location is still viable or whether elevated installation or closet relocation makes more sense. New gas furnace installations in this market typically fall between $4,130–$8,850 depending on access difficulty and whether duct fabrication is required.
Furnace Tune-Up
San Anselmo’s fall Diablo wind season brings smoke and particulate that loads up filters fast. A furnace tune-up in San Anselmo runs $95–$235 and includes combustion analysis, heat exchanger inspection, and filter assessment calibrated to our heavier-than-coastal particulate load. We recommend scheduling before October, when the first cold snaps hit the valley floor and our calendar fills with no-heat calls from Fairfax to Larkspur.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a safety issue we take seriously — carbon monoxide risk is real, and San Anselmo’s older furnaces are reaching the age where metal fatigue shows up. We inspect with visual and combustion testing; if replacement is needed, we’ll quote honestly against full system replacement so you can make an informed call. In flood-zone homes near the creek, we also check for corrosion from past water exposure that other inspectors might miss.

Trusted Brands We Service in San Anselmo
We carry factory training or deep field experience on nine major HVAC brands, including Carrier in San Anselmo, plus Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For San Anselmo customers, this means we stock common Rheem and Goodman ignition modules, gas valves, and blower motors locally — no two-week wait for a part that leaves your family without heat. When we encounter a Daikin modulating furnace in a newer retrofit off Sir Francis Drake, or a York system in a commercial building near the Hub, we’re not guessing. We’ve worked on your specific model before.
Common Heating & Furnace Problems We See in San Anselmo Homes
- Original gravity furnaces failing in Craftsman bungalows. These units have no blower motor, rely on convection, and were designed for an era when “heating” meant taking the chill off. Homeowners on Crescent Road and San Anselmo Avenue are often shocked how much comfort a modern forced-air system delivers — and how complex the retrofit is in homes with no existing duct paths.
- Corroded components in flood-zone crawl spaces. San Anselmo Creek’s 2005 flooding submerged mechanical equipment in dozens of homes, and subsequent smaller events have kept moisture levels high in pier-and-beam foundations near the town center. We regularly find rusted burner assemblies and deteriorated heat exchangers in these locations, often requiring equipment relocation as part of any lasting fix.
- Undersized systems in hillside ranches with expanded floor plans. Mid-century homes in upper San Anselmo neighborhoods were often built with modest original heating, then had additions that pushed load calculations far beyond capacity. The result: systems that run constantly, burn out prematurely, and still leave rooms cold.
- Reach-code confusion during replacement quotes. Marin County’s push toward all-electric heating has created uncertainty for homeowners who assumed gas replacement was straightforward. We clarify what’s currently permitted, what rebates apply to heat-pump conversions, and whether a dual-fuel approach makes sense for your specific home and timeline.

FAQs — Heating & Furnace in San Anselmo
We typically schedule same-day or next-day service for San Anselmo furnace breakdowns, with our Emergency & Commercial HVAC in San Anselmo available for urgent no-heat situations. Our routing through the Ross Valley means we’re rarely more than 20 minutes from the 94960 ZIP during business hours. Call (877) 454-5066 — we’ll give you a real arrival window, not a four-hour guess.
Yes — we service the full 94960 and 94979 ZIP codes, from the flat creek-adjacent blocks near the Hub to the steep hillside ranches above Sleepy Hollow and the upper Sir Francis Drake corridor. Hillside access and tight driveways are familiar territory; we bring the right equipment for properties where standard service vans don’t fit.
Our AC Repair & Installation in San Anselmo team also handles emergency HVAC service for urgent residential and commercial heating failures. When your furnace quits on a freezing January night or your heat exchanger crack is venting combustion gases, we prioritize the call. Anthony Moreno handles after-hours emergencies personally when volume requires it — you’re not getting an on-call newbie.
San Anselmo pricing is comparable to Fairfax and San Rafael, though our valley’s older housing stock and flood-zone access challenges can push some jobs toward the higher end of the $175–$825 repair range. Homes with original gravity furnaces or submerged crawl spaces simply require more labor than newer construction in Kentfield or Larkspur. We quote before starting work so you know exactly where your job falls.
We stand behind our heating and furnace installations with solid warranty coverage and follow-through that doesn’t disappear after the check clears.

For repair work, we guarantee our labor and parts for a period that lets you sleep soundly. Call (877) 454-5066 for exact warranty details on your specific system — estimates are free, and we’ll put it in writing before any work begins.
