We know Corte Madera’s streets well. From the ranch homes tucked along Paradise Drive to the bayside neighborhoods west of US-101 near the Corte Madera Ecological Reserve, we’ve spent nearly two decades servicing the heating systems that keep Marin County comfortable through damp, chilly winters. Owner Marcus Feldman still manages every job personally, so when you call Crestview Heating & Air California at (844) 560-6978, you’re talking to someone with skin in the game, not a dispatcher reading from a script.
Why Crestview Heating & Air California Is Corte Madera’s Preferred Heating & Furnace Company
Our reputation in Corte Madera was built one service call at a time. We’ve worked on wall furnaces in 1950s tracts near Tamalpais Drive, replaced corroded heat exchangers in homes overlooking the bay, and designed ductwork for clients in the Cove area who finally wanted central heat after decades of patchwork solutions.
250+ customers left reviews, and those reviews average 4.8 stars. That volume matters. It means real performance across real jobs, not a handful of cherry-picked testimonials. Marcus Feldman serves as both owner and Service Manager, so the accountability structure is simple: the person who answers your questions is the same person ensuring the work gets done right.
We’re based in San Jose, but Corte Madera is firmly in our service territory. Our technicians make the run up 101 regularly, and we prioritize emergency calls in Marin when heat goes out on a foggy January night. We know the local conditions that kill furnaces here: salt air, crawl-space moisture, obsolete parts. That knowledge saves you time and money.
Our Heating & Furnace Services in Corte Madera
Furnace Repair in Corte Madera
Most Corte Madera furnace repair calls we handle fall in the $175–$825 range. The town’s legacy wall furnaces and early central systems fail in predictable ways here: pilot assemblies corroded by marine air, thermocouples weakened by salt spray, blower motors strained by decades of dust from unsealed crawl spaces. We stock common parts for Trane, Lennox, and Rheem systems, and we carry universal retrofit components for brands that stopped manufacturing decades ago.
Furnace Replacement in Corte Madera
A full furnace replacement in Corte Madera typically costs $3,500–$7,500. The wide range reflects a local reality: many homes, especially west of US-101 and in neighborhoods near the Corte Madera Ecological Reserve, were built without central ductwork. Replacing a wall furnace with another wall furnace is straightforward. Upgrading to a central system means designing and installing ducts through crawl spaces, attics, or closet chases. We’ve done both, and we’ll tell you honestly when a simpler repair makes more sense than a full retrofit.
Furnace Tune-Up in Corte Madera
Our tune-ups run $95–$235 and include combustion analysis, heat exchanger inspection, and cleaning of burners and sensors. In Corte Madera’s marine climate, we pay special attention to corrosion on electrical connections and condensate drainage. The chronic humidity here means mold colonies in drain lines that would stay clear in drier towns. A yearly tune-up catches these issues before they become January emergencies.
Heat Exchanger Repair & Replacement in Corte Madera
Heat exchanger work ranges from $150–$700 for repair, up to full furnace replacement if the exchanger has failed catastrophically. This is where Corte Madera’s geography hits hardest. The salt-laden air off San Francisco Bay accelerates rust on steel heat exchangers, particularly in wall furnaces installed in exterior walls facing the water. We’ve replaced heat exchangers on 15-year-old units that should have lasted 25, simply because of bay exposure. If your furnace is producing a sulfur or “rotten egg” odor, shut it off and call us. That’s a cracked exchanger, and it’s a carbon monoxide risk.
Ignitor Replacement in Corte Madera
Modern hot-surface ignitors and older pilot-light assemblies both fail faster in Corte Madera’s damp climate. Moisture infiltration into combustion chambers causes premature cracking and weak spark. We carry replacement ignitors for Goodman, Rheem, and Lennox systems, plus universal pilots for legacy wall furnaces that manufacturers no longer support.
Gas Valve Repair in Corte Madera
Gas valve repair runs $150–$700. Here’s a growing problem in Corte Madera: the single-stage gas valves in 1960s and 1970s wall furnaces are becoming obsolete. Manufacturers stopped producing many of these models years ago, and remaining inventory is dwindling. When we can’t source a replacement valve, we walk you through your options: a compatible modern valve with adapter kit, or full furnace replacement. We’ll never push replacement when repair is viable, and we’ll never patch a repair that’s unsafe.

Common Heating & Furnace Problems We See in Corte Madera Homes
- Salt-air corrosion on heat exchangers and pilot assemblies. In bayside neighborhoods west of US-101, we regularly find wall furnaces with rusted-through heat exchangers and pitted pilot burners. The marine air here is noticeably more corrosive than in hillside Marin towns like Mill Valley or Fairfax just a few miles east. Units facing the bay often need replacement 8–10 years sooner than inland equivalents.
- Condensate drain lines clogging with mold in damp crawl spaces. The low-lying parcels on bay-fill and former marshland have persistently moist crawl spaces. Any existing ductwork down there grows mold on insulation, and condensate drains from high-efficiency furnaces clog with biological growth. We clear these lines and can install condensate pumps with overflow shutoffs where gravity drainage fails.
- Legacy gas valves becoming obsolete with no replacement parts available. The single-stage valves in 1960s–70s wall furnaces are a disappearing commodity. We’ve encountered three Corte Madera homes in the past year where the original valve was simply unobtainable. In those cases, we source modern compatible valves or recommend replacement if the furnace is already marginal.
- Heat pumps and ductless systems corroding prematurely near the shoreline. Outdoor cabinets and refrigerant lines on bay-facing properties show pitting and fastener failure within 7–10 years. We specify coastal-grade coatings and elevated mounting where possible, and we factor replacement timelines into our recommendations for shoreline homes.

FAQs — Heating & Furnace in Corte Madera
Usually yes, if the heat exchanger is intact and replacement parts are available. A new thermocouple or pilot assembly typically runs $150–$400, far less than replacement. However, if the heat exchanger shows rust-through from salt-air corrosion, especially in bayside neighborhoods, replacement becomes the safer choice. Call (844) 560-6978 and we’ll inspect it honestly.
Yes, the Town of Corte Madera requires permits for furnace replacement, and inspections for gas line connections and venting. We handle permit applications as part of our replacement service, and we coordinate inspections so you’re not chasing paperwork. Most permits add $150–$400 to the total project cost depending on scope.
Heat pumps are increasingly the right choice here. Corte Madera’s mild winters rarely drop below 40°F, so heat pumps operate efficiently without strain, and they provide cooling for the handful of summer days that top 80°F. For homes without ductwork, ductless mini-splits eliminate the need for invasive retrofitting. We’ve installed both in Cove area homes and along Paradise Drive with strong results.
Yes, in most cases. We design duct systems using attic runs, closet chases, and crawl-space routes that avoid opening finished walls. Some homes need one or two small soffits or ceiling drops, but we minimize intrusion. We’ve completed full central-system retrofits in 1950s Corte Madera ranches with no visible ductwork inside living spaces.
Once yearly, ideally in early fall before heating season. The salt air and humidity here accelerate wear on burners, sensors, and electrical connections. Annual service catches corrosion early, clears condensate drains before mold blocks them, and verifies heat exchanger integrity. Skipped maintenance is how small problems become $3,500 replacements. Call (844) 560-6978 to schedule your tune-up — estimates are free.
