Fast, Reliable Heating & Furnace Across Tiburon
Heating and furnace repair in Tiburon typically runs $150–$700 for repairs and $3,500–$7,500 for full replacement, with most service calls completed same-day. Tiburon’s salt-laden marine air and hillside homes create furnace problems you won’t find inland — corrosion, ductwork mold, and heat loss through oversized bay windows — which is why you need a technician who knows this peninsula specifically, not just Marin County generally.
We’re Stonegate Heating & Air California, and our Heating & Furnace team makes the trip across the Richardson Bay Bridge to Tiburon regularly. Owner Jason Trent supervises every project personally, and in 16 years we’ve built nearly 500 verified reviews at a 4.7-star average. We know the 94920 ZIP well — from the 1950s ranch homes tucked into the Bel Aire hills to the custom builds on the Tiburon Ridge. Call (855) 467-1888 for a free estimate.
Why Stonegate Heating & Air California Is Tiburon’s Preferred Heating & Furnace Company
Tiburon homeowners have told us the same story repeatedly: they called a “Marin County” HVAC company and got a tech from Novato who’d never worked on a hillside home with crawlspace access so tight you need to shimmy on your side. That doesn’t happen with us. Jason Trent is on the job as Field Supervisor, not managing from a Sacramento office. He knows Tiburon’s terrain because he’s crawled under those houses.
Our 499 reviews at 4.7 stars include plenty from Tiburon and nearby Sausalito. Homeowners mention the same things: we show up when we say we will, we explain what’s actually wrong without upselling, and we stock parts for nine major brands so we’re not ordering a gas valve that takes a week to arrive. Whatever brand you have — Carrier, Trane, Lennox, Goodman, or others — we carry the common failure parts or can source them fast through our Bay Area supply chain.
Response time to Tiburon is typically same-day or next-morning, depending on when you call. Emergency HVAC is available. We don’t subcontract to random technicians; the person who answers your questions is accountable to Jason directly.
Our Heating & Furnace Services in Tiburon
Furnace Repair in Tiburon
Furnace repair in Tiburon costs $150–$700 depending on the part and accessibility. The most common call we get? Ignitor failure on a 20-year-old furnace that finally gave out on the first cold night. But Tiburon has a second, sneakier problem: salt air intrusion through crawlspace vents corrodes the heat exchanger from the outside, causing carbon monoxide leaks that standard CO detectors near the living space might miss. We perform combustion analysis on every repair call to catch this. We recently serviced a 1960s hillside home on Paradise Drive where the original forced-air furnace had a heat exchanger rusted through by decades of salt air intrusion through the crawlspace vents. We replaced it with a sealed-combustion unit that draws intake air from the leeward side of the house, and installed a corrosion-protected evaporator coil to prevent a repeat failure.
Furnace Replacement in Tiburon
Full furnace replacement in Tiburon runs $3,500–$7,500. The upper end usually involves hillside homes where we need to crane equipment in or build custom platforms on steep grades. Tiburon’s housing stock — heavy on 1950s–1970s construction with original furnaces — means we’re often pulling out units that are 25–40 years old. These legacy systems were sized for the house as originally built, before the giant picture windows went in. We run proper load calculations that account for the solar gain those windows create, or you’ll end up with cold pockets in winter and an oversized, short-cycling furnace that dies young.
Furnace Tune-Up in Tiburon
A furnace tune-up in Tiburon costs $80–$200 and should happen annually, ideally in early fall before the first cold snap has every HVAC company in Marin booked solid. Our tune-ups include combustion analysis, heat exchanger inspection with a borescope, and ductwork assessment for mold. That last point matters especially here. Tiburon sits in a fog-sheltered microclimate that’s warmer and sunnier than Mill Valley, but the overnight humidity stays high enough to promote mold growth inside aging ductwork. Homeowners call us thinking their furnace is failing when it’s actually microbial buildup choking airflow. We catch that distinction.
Heat Exchanger Inspection & Replacement in Tiburon
Heat exchanger failure is the repair that separates a $400 service call from a $6,000 replacement. In Tiburon, salt-air corrosion eats exchangers from the outside in, not the inside out like typical wear. The exterior of the exchanger rusts through the cabinet and casing first, creating pinholes that vent CO into the crawlspace or mechanical room. This pattern is rare in San Rafael or Novato. We inspect with visual and electronic methods, and if replacement is needed, we specify corrosion-resistant materials and sealed combustion to break the cycle.

Trusted Brands We Service in Tiburon
We’re certified to work on nine leading HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Tiburon customers, this means no “we don’t service that brand” dead end. We stock common ignitors, gas valves, and control boards for Carrier, Trane, and Lennox locally, and our relationship with Bay Area distributors gets us same-day or next-day parts for Goodman and the others. From a single-room repair to a full system replacement, one team handles it.
Common Heating & Furnace Problems We See in Tiburon Homes
- Salt-air corrosion of heat exchangers and electrical components. Tiburon’s peninsula geography puts it surrounded by San Francisco Bay water on three sides, bathing every outdoor HVAC unit in persistent salt-laden marine air that corrodes aluminum condenser fins, electrical contacts, and refrigerant line connections far faster than in any neighboring inland Marin town. Furnaces aren’t immune — the salt penetrates crawlspaces and mechanical rooms, attacking the heat exchanger exterior and control board contacts.
- Oversized bay-view windows overwhelming heating design. The 1950s–1970s hillside homes, plus newer custom builds, feature massive west- and southwest-facing glass for the views. Standard furnaces can’t overcome the radiant heat loss through that glass on cold clear nights. We redesign duct runs and specify higher-output registers for those zones.
- Mold in ductwork masquerading as furnace failure. High overnight humidity in fog-sheltered Tiburon promotes mold growth inside aging ductwork, which can be misdiagnosed as a furnace problem when airflow drops due to microbial buildup. Homeowners crank the thermostat, the furnace runs longer, and they assume the heater is dying. It’s the ducts.
- Legacy equipment past service life with obsolete parts. Many Tiburon homes still run original furnaces from the 1960s and 1970s. Some parts are no longer manufactured. We maintain a network of salvage suppliers, but eventually retrofit becomes the only option. We tell you honestly when we’ve reached that point.

FAQs — Heating & Furnace in Tiburon
Yes. Salt-laden air penetrates crawlspace vents, garage door gaps, and mechanical room louvers, corroding heat exchangers and electrical contacts from the outside in. We see this on Tiburon service calls far more than in inland Marin. The solution is sealed-combustion furnaces and corrosion-protected components. Call (855) 467-1888 and we’ll inspect your current setup.
Not necessarily. Oversized west- and southwest-facing glass creates radiant heat loss that standard furnace sizing doesn’t account for. We see cold pockets in living rooms with the best views. We run proper load calculations and often redesign duct runs to those zones. A free estimate includes this assessment.
Annually, in early fall before demand spikes. The salt-air and humidity factors here accelerate wear compared to drier inland climates. Our tune-up includes combustion analysis and duct mold check — both especially relevant in Tiburon. Schedule now and beat the November rush.
Usually yes, especially if your current furnace is 15+ years old and unsealed-combustion. High-efficiency sealed units eliminate salt-air intrusion into the combustion chamber, last longer here, and qualify for utility rebates. We calculate your actual payback based on Tiburon’s heating degree days and your home’s specifics.
Heat exchangers cannot be safely repaired once corroded — replacement of the exchanger or the entire furnace is required. In Tiburon, where salt corrosion causes exterior rust-through, we often find the damage is too extensive for exchanger-only replacement. We perform combustion analysis to verify and give you straight options. Call (855) 467-1888.
