Fast, Reliable Heating & Furnace Across Fairfax
Furnace repair in Fairfax typically runs $175–$825 and most calls are handled same-day when you reach us by early afternoon. We’re Meridian Heating & Air, and our Heating & Furnace team knows the Ross Valley’s older housing stock inside and out — from the wall heaters still running in Perry Street bungalows to the floor furnaces tucked beneath Cascade Canyon cottages. Anthony Moreno, our founder, still carries the tools and shows up on the job himself. Call (877) 454-5066 for a free estimate.
Why Meridian Heating & Air Los Angeles Is Fairfax’s Preferred Heating & Furnace Company
We’ve been at this nearly two decades, and the 286 customers who’ve left reviews averaging 4.8 stars include plenty from right here in Fairfax. They mention the same thing repeatedly: Anthony arrives, diagnoses the actual problem, and fixes it without the runaround.
Fairfax sits just far enough inland that winter nights on the valley floor drop into the 30s while coastal Marin stays mild. That temperature swing catches homeowners off guard when their original wall heater fails at 11 PM. We understand the urgency because we’ve driven Bolinas Road at midnight to reach a cold house in the 94930 zip.
Our familiarity with Fairfax’s pre-1960 housing means we don’t waste your time proposing solutions that won’t fit. Low attic clearance in those craftsman bungalows, irregular floor plans on sloped lots, original floor furnaces with rusted combustion chambers — we’ve addressed each of these dozens of times. You get experience, not experimentation.
And because Anthony serves as Lead Installer, the expertise you speak with on the phone is the same expertise that arrives at your door. No handoffs to rotating subcontractors who’ve never seen a Fairfax hillside cabin.
Our Heating & Furnace Services in Fairfax
Furnace Repair
Most Fairfax homes never had a conventional furnace to begin with. When we say “furnace repair” here, we’re often talking about the original floor furnaces in the 1920s cottages near the town center, the wall heaters in the post-war bungalows along Broadway, or the gas-fired units retrofitted into hillside homes in the 1980s. A typical repair in Fairfax runs $175–$825 depending on whether we’re replacing a failed ignitor, addressing a cracked heat exchanger, or tracking down a faulty gas valve. We carry common parts for Rheem, York, and Bryant systems to avoid ordering delays that leave you cold.

Furnace Replacement
When replacement becomes the smarter investment, Fairfax’s housing stock presents a specific challenge. Most of these homes lack central ductwork entirely, and the low attics and crawl spaces make retrofitting ducts impractical or impossible. We’ve guided many Fairfax homeowners toward Fairfax AC Repair & Installation options like ductless heat pump solutions rather than forcing a conventional furnace into a structure that fights it. That said, when a ducted system does make sense — typically in homes that have already been partially updated — we install properly sized units from our nine supported brands. A full replacement with new equipment generally falls in the $4,130–$8,850 range depending on complexity.

Furnace Tune-Up
Fairfax’s combination of wooded canyon moisture and valley-floor temperature swings puts unusual stress on heating components. A proper tune-up here means checking for condensate drainage issues in shaded, north-facing installations, verifying gas pressure after seasonal temperature shifts, and inspecting heat exchangers for corrosion accelerated by the area’s humidity. Our tune-ups run $95–$235 and include a full combustion analysis. We recommend scheduling before the first cold snap hits the Ross Valley, since that’s when every HVAC company in Marin gets overwhelmed.

Heat Exchanger Inspection & Replacement
This is where we get direct about safety. A cracked heat exchanger in any gas-fired heating system can leak carbon monoxide into your living space. In Fairfax’s older homes, where original floor furnaces and wall heaters may have been running for 40+ years, this risk is elevated. We use visual inspection, combustion analysis, and when warranted, camera examination to verify heat exchanger integrity. If replacement is necessary, we’ll tell you honestly whether it makes financial sense on an aging unit or whether redirecting toward a new system is the wiser path. We do not perform patchwork repairs on compromised heat exchangers — full stop.

Trusted Brands We Service in Fairfax
We work on your brand — that’s been our approach for 19 years. Our factory training and field experience cover nine major manufacturers: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Fairfax customers, this matters because we stock common ignitors, gas valves, control boards, and heat exchanger components for Rheem, York, and Bryant systems locally. That inventory means faster turnaround on repairs, especially during mid-winter cold snaps when waiting three days for a part isn’t an option. We’ve also found that Daikin and York equipment performs particularly well in the ductless configurations that suit so many Fairfax homes. Whatever’s heating your house, we’ve likely serviced it before.
Common Heating & Furnace Problems We See in Fairfax Homes
- Failed ignitors in original floor furnaces. The piezo-electric and hot-surface ignitors in pre-1960 floor furnaces throughout the 94930 and 94978 zips have exceeded their design life by decades. We replace these with modern, compatible components that restore reliable ignition without replacing the entire unit.
- Corroded heat exchangers from canyon moisture. Homes on the wooded, north-facing slopes near Cascade Canyon experience persistent shade and moisture year-round, which accelerates coil corrosion and heat exchanger deterioration in gas-fired units. Technicians coming from drier inland markets consistently underestimate this failure pattern.
- Undersized wall heaters in expanded bungalows. Many Fairfax craftsmen have had additions built over the years, but the original wall heater was never upgraded to handle the additional load. The result is a house that’s warm near the heater and cold everywhere else — a problem we solve with proper load calculation and right-sized equipment.
- Gas valve failures after temperature swings. The Ross Valley’s wide seasonal range, from summer highs of 95–105°F to winter lows in the 30s, causes repeated thermal cycling in gas valves. We see stuck and leaking valves more frequently here than in more temperate coastal Marin communities.
