A live person answers 24 hours a day, and we’ll send you the name and photo of the technician who’s coming before they ever knock on your door.
We know Novato’s neighborhoods well. From the original ranch homes off Rowland Boulevard and the split-levels near San Marin Drive to the redeveloped Hamilton area, we’ve worked on the heating systems that keep this city warm through December fog and January frost. Novato sits in a valley pocket north of the marine layer that cools the rest of Marin County, which means it runs hotter in summer and colder in winter than most people expect from a “Marin address.” That temperature swing puts real demand on furnaces that were often installed during the 1950s – 1970s building boom, when the assumption was that Marin barely needed heat at all.
Our dispatch and scheduling are coordinated from our San Francisco Bay Area office, but our crews serve Novato locally. We carry common parts for Rheem, York, Daikin, Bryant, and other major brands so we’re not waiting on a warehouse run while your house gets cold.

Boiler Repair in Novato
Boiler Repair in Novato addresses hydronic heating systems that circulate hot water or steam through radiators, baseboards, or in-floor tubing. While less common than forced-air gas furnaces in Novato’s 1950s – 1970s housing stock, boilers do appear in some Hamilton neighborhood conversions and in a handful of mid-century homes near downtown that were built with radiant heat. A typical boiler repair in Novato runs $150 – $700, same as our furnace repair range, depending on whether the issue is a circulating pump, zone valve, expansion tank, or heat exchanger leak.
Signs Your Boiler Needs Attention
Watch for cold radiators despite the thermostat calling for heat, water pooling near the boiler cabinet, or pressure readings that swing wildly on the gauge. In Novato’s older homes, sediment buildup from decades of mineral-heavy Marin County water is a frequent culprit. We flush and descale systems where it’s cost-effective, and we tell you honestly when replacement makes more sense.
Boiler Safety and Efficiency Checks
Gas-fired boilers vent combustion gases that must exhaust properly. We inspect venting, test for carbon monoxide, and check combustion efficiency on every boiler call. This isn’t upsell. It’s basic safety, and we document what we find in writing.
Gas Furnace Repair in Novato
Gas Furnace Repair in Novato covers the single-zone forced-air systems that dominate this city’s housing stock, from original 1960s units in Ignacio ranch homes to later models in the Hamilton redevelopment. The job involves diagnosing ignition failures, heat exchanger cracks, blower motor problems, gas valve issues, and the static pressure problems that are uniquely common here. Most repairs fall between $150 – $700.
Heat Exchanger and Combustion Safety
A cracked heat exchanger can leak carbon monoxide into your home. We inspect with visual checks and combustion analysis, and we show you what we find. If the heat exchanger is compromised, we explain your options: repair if the part is available and cost-effective, replace if the furnace is past its reliable service life. No scare tactics. Just facts and a written price.
Airflow and Static Pressure Corrections
Here’s where Novato gets interesting. Many homeowners have added high-MERV filters to combat wildfire smoke, but the original 1970s ductwork in these ranch homes wasn’t designed for that resistance. The blower motor strains, the heat exchanger overheats, and the high-limit switch trips. We measure static pressure, size the filter properly, and correct duct restrictions where possible. The furnace runs better and lasts longer.
Trusted Brands We Service in Novato
We service all major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Novato customers, this means we stock common parts locally for Rheem, York, Daikin, and Bryant systems, and we can source same-day or next-day for others. We’ve worked on enough Carrier and Trane units in the Rowland Boulevard and Hamilton areas to know their typical failure patterns in this climate. Whether your furnace is two years old or thirty, we diagnose it honestly and repair it if it makes sense.
Common Furnace Repair Problems We See in Novato Homes
- Cracked heat exchangers in original 1960s – 70s furnaces. The heating cycles these units endured through Novato’s colder winter nights, combined with metal fatigue from decades of expansion and contraction, eventually create cracks. We find them during combustion tests, not guesswork.
- Blower motor and capacitor failures from high-MERV filter upgrades. Wildfire smoke season has driven many Novato homeowners to MERV-13 or higher filters, but the original ductwork can’t move enough air through them. The motor overheats, the capacitor fails, and the furnace short-cycles or shuts down entirely.
- Hamilton neighborhood airflow starvation. The redeveloped base housing often has supply runs that were never designed for residential comfort loads. Equipment tests fine in isolation, but rooms stay cold because the duct simply can’t deliver enough heated air.
- Corrosion and condensation on west-side venting. The Petaluma Gap pushes moist marine air across western Novato neighborhoods, accelerating rust on furnace vent pipes and heat exchangers. Eastern bay-side homes see different problems: dry heat that cooks capacitors and control boards.

FAQs About Furnace Repair in Novato
Your Novato furnace likely has different ductwork, a different filter setup, or both. Novato’s older ranch and split-level homes often have original heat-only ductwork that was never sized for the airflow demands of modern filtration. When you add a high-MERV filter for wildfire smoke, static pressure climbs and the furnace overheats, causing the high-limit switch to trip. San Rafael homes, closer to the coast and often newer, may not have this exact combination of aging infrastructure and smoke-season upgrades. We measure static pressure and correct the root cause, not just the symptom. Call (984) 538-9003 for a free estimate.
The Hamilton redevelopment converted military structures with duct configurations that were jury-rigged for residential use, not designed for it. Supply runs may be undersized, insulation mismatched, or return pathways blocked. Your furnace can test perfectly on paper while failing to deliver even comfort because the infrastructure behind the walls was never meant for modern residential standards. We map airflow and identify the duct restrictions that inspections miss. Call (984) 538-9003 for a free estimate.
Smoke season has pushed many Novato homeowners to high-MERV filters that their original ductwork cannot handle, leading to blower motor strain, heat exchanger overheating, and premature failure. A proper furnace repair in Novato now often includes evaluating whether your filter rack and duct system can support the filtration you need, or whether you need a different solution like a standalone air purifier. We address the whole system, not just the broken part. Call (984) 538-9003 for a free estimate.
Yes. The moist marine air and gusty afternoon winds channeled through the Petaluma Gap accelerate corrosion on furnace venting, heat exchangers, and burner assemblies in western Novato neighborhoods. Eastern neighborhoods near San Pablo Bay see the opposite problem: trapped radiant heat that shortens capacitor and control board life. Same city, different microclimates, different failure patterns. We know which issues to look for based on where you live. Call (984) 538-9003 for a free estimate.
Repair if the heat exchanger is sound and parts are available; replace if efficiency is below 70%, repair costs exceed 40% of replacement, or safety issues like cracked combustion chambers are present. Many 1960s Novato furnaces are simple, durable, and worth fixing once or twice more. We give you the numbers honestly: repair cost, expected remaining life, and replacement cost with current utility rebates. No pressure either way. Call (984) 538-9003 for a free estimate.
Brandt comes from an old word for a firebrand – a fitting name for the work of keeping a home warm. If your furnace is struggling anywhere in Novato, from the original ranch neighborhoods to the Hamilton redevelopment, we’re ready to diagnose it honestly and fix it right.
