Why Redwood Heating & Air San Diego Is Mountain View’s Preferred Heating & Furnace Company
Gregory Hahn founded this company and still leads every technical decision.

Our Heating & Furnace Services in Mountain View
Furnace Repair
Most Mountain View furnace repair calls we receive aren’t furnaces at all, strictly speaking. They’re wall heaters in 94040 tract homes or floor furnaces in Waverly Park ranches, many manufactured by Wedgewood or similar defunct brands whose parts catalogs dried up decades ago. A typical furnace repair in Mountain View runs $150–$700, though we always inspect first to determine whether the unit is actually serviceable or if we’re past the point of diminishing returns.
On a recent job in the Rex Manor neighborhood, we replaced a rusted-out 1960s floor furnace with no existing ductwork. After evaluating the home’s shallow soffits and lack of attic access, we installed a Daikin multi-zone ductless mini-split system with smart thermostats, giving the homeowners zoned heating and cooling for the first time. The total cost of repair versus upgrade: $850 for a temporary patch versus a $6,200 installation that eliminated future breakdowns and added AC.
Furnace Replacement
In Mountain View, “furnace replacement” frequently means “heating system invention.” The bulk of Mountain View’s single-family stock is 1945–1975 ranch-style and small bungalow construction, much of it in neighborhoods like Rex Manor and Waverly Park, where original wall or floor furnaces are still common and attic and soffit space is too limited for conventional duct runs. Contractors pulling permits at the Mountain View Building Division routinely encounter 1950s homes in the 94040 and 94041 ZIP codes where the only original “HVAC” is a single Wedgewood wall heater, meaning a “furnace replacement” job is actually a whole-home duct-design-and-install project, or a pivot to multi-zone ductless.
That conversation, and the higher ticket it produces, is a Mountain View-specific pattern that rarely comes up just a few miles east in San Jose’s wider duct-equipped tract neighborhoods. Furnace replacement in Mountain View typically runs $3,500–$7,500, with complex retrofits at the higher end.
Furnace Tune-Up
Mountain View’s position close to the southern arm of San Francisco Bay channels marine layer fog that keeps summer highs 10–15°F below same-day readings in San Jose. That same persistent coastal dampness accelerates mold growth in poorly ventilated crawl spaces and aging duct systems, making IAQ and ventilation add-ons a consistent upsell opportunity. A furnace tune-up in Mountain View costs $80–$200 and includes combustion analysis, heat exchanger inspection, and moisture assessment in crawl spaces where we frequently find deterioration that Bay-Area-dry Santa Clara homes simply don’t experience.
Heat Exchanger Inspection & Replacement
Marine-layer moisture accelerates heat exchanger rust and mold in crawl spaces, leading to premature failure and IAQ issues. In Mountain View’s older housing stock, we find cracked or corroded heat exchangers at rates higher than inland Bay Area cities. This is genuinely dangerous, a cracked heat exchanger can leak carbon monoxide into living spaces. We recommend a trained professional for any heat exchanger work, never DIY. If we find cracks during inspection, we’ll show you the camera footage and explain whether replacement of the exchanger alone makes sense or if the furnace’s age and condition point toward full system replacement.
Gas Valve Repair
Legacy wall and floor furnaces in Mountain View often have original gas valves that have cycled on and off for 50+ years. When these fail, replacement valves are frequently obsolete. We carry common retrofits for Mountain View’s housing stock, but we’ll also be direct if your valve is unsourceable and the smarter path is system replacement.

Trusted Brands We Service in Mountain View
We service your brand. Gregory Hahn holds a Master Technician designation and maintains factory-trained or deep field experience across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Mountain View’s tech-affluent homeowner base, which drives unusually high demand for all-electric heat pump systems with smart-home integration, our fluency with Daikin and Bryant ductless lines matters. We stock local parts for faster turnaround on common Mountain View repairs, and our multi-brand capability means we won’t try to shoehorn your home into the one system we know how to install.
Common Heating & Furnace Problems We See in Mountain View Homes
- Legacy wall or floor furnaces past their service life, with no replacement parts available for 1960s Wedgewood models. We encounter these weekly in 94040 and 94041. The ignitor clicks, the pilot won’t hold, or the gas valve won’t open, and the part number returns “discontinued” from every supplier. At that point, we pivot to ductless or mini-split options that your home’s structure can actually accommodate.
- Original duct systems (if any) installed in 1950s tract homes have corroded or collapsed, requiring complete redesign. Some Mountain View homes have partial ductwork from a 1980s or 1990s retrofit, but it’s often galvanized flex duct in unconditioned crawl spaces, degraded by decades of marine-layer moisture. We assess what’s salvageable and what needs complete replacement.
- Marine-layer moisture accelerates heat exchanger rust and mold in crawl spaces, leading to premature failure and IAQ issues. Winter lows rarely freeze in Mountain View, but the persistent coastal dampness doesn’t dry out. We find rust patterns on heat exchangers here that we simply don’t see in drier inland climates, and we address ventilation as part of any lasting solution.
- Newer high-density infill along the North Bayshore corridor and near Castro Street adds multi-family and mixed-use buildings with entirely different commercial-grade HVAC demands. These buildings need rooftop package units or VRF systems, not residential wall furnaces, and our commercial team handles both the technical complexity and the Mountain View permitting requirements.
Pricing for Heating & Furnace in Mountain View, CA
We’re transparent about what heating work costs in Mountain View because these projects vary enormously based on your home’s infrastructure, or lack thereof.
| Service | Typical Range in Mountain View |
|---|---|
| Furnace Repair | $150–$700 |
| Furnace Tune-Up | $80–$200 |
| Furnace Replacement | $3,500–$7,500 |
What drives the high end? Homes with no ductwork, limited soffit space, or obsolete electrical panels require more labor and materials. The Daikin multi-zone system we installed in Rex Manor fell at $6,200, right in the replacement range, because it solved heating and cooling simultaneously without inventing duct runs where none could fit. Call (844) 875-9451 for an exact quote, estimates are free.

FAQs — Heating & Furnace in Mountain View
Usually no, the parts are discontinued and we can’t fabricate safety-critical gas components. We can inspect it to confirm, but most Wedgewood units we encounter in 94040 and 94041 are past repair and we pivot to ductless mini-split or wall-mounted heat pump options that fit homes with no duct infrastructure. Call (844) 875-9451 and we’ll evaluate your specific unit.
Yes, the Mountain View Building Division requires permits for gas furnace replacement, and inspections for combustion safety. We handle permit submission and scheduling as part of our replacement service. The process typically adds 3–5 business days to the project timeline.
Intermittent operation usually points to a failing gas valve or flame sensor, not the ignitor itself, which typically fails completely. In Waverly Park’s legacy systems, we also see draft inducer motors overheating and cycling on thermal limit. We’ll diagnose with a multimeter and manometer, not guesswork. Call (844) 875-9451 for same-week service in Waverly Park.
Only if the ductwork is intact and properly sized for heat pump air volumes, which 1970s flex duct in Mountain View crawl spaces rarely is. We test static pressure and inspect for moisture damage first. Often we find the ducts are too leaky or too small, and we recommend either duct replacement or bypassing them entirely with a ductless system.
A cracked heat exchanger is a safety hazard that requires immediate action, but you don’t always need full replacement. If the furnace is under 12 years old and the manufacturer still produces the exchanger, replacement is sometimes viable. In Mountain View’s housing stock, however, we more commonly find 40+ year old units where exchanger replacement is impractical and a modern heat pump or ductless system is the smarter investment. We’ll show you the camera footage and both options with real numbers.
