We’re Crestview Heating & Air California, and we’ve been keeping San Bruno homes warm through the city’s famously cold, fog-bound winters for nearly two decades. The San Bruno Gap doesn’t just make this city chilly — it creates furnace problems you won’t find in San Jose or even San Mateo. Salt-laden marine air accelerates corrosion on outdoor components. Original post-WWII ductwork fights modern equipment. We’ve seen it all, fixed it all, and we still show up personally. Owner Marcus Feldman serves as our Service Manager, so the person answering your questions is the same one ensuring the work gets done right.

Our 19 years of HVAC experience means we’ve worked on virtually every system type, age, and configuration a San Bruno homeowner could own.
Our Heating & Furnace Services in San Bruno
Furnace Repair
San Bruno’s combination of aging furnaces and constant heating demand means repair calls here outnumber cooling calls by a wide margin. We handle everything from failed blower motors to control board replacements on units dating back to the 1960s. Because the city sits in the San Bruno Gap, we also see accelerated corrosion on outdoor-mounted components that inland technicians might misdiagnose. A typical furnace repair in San Bruno runs $150–$700 depending on the part and accessibility.
Furnace Replacement
This is where San Bruno’s housing stock gets complicated. Those post-WWII tract homes — built late 1940s through mid-1960s — were fitted with minimal gas-fired forced-air furnaces and uninsulated duct runs through drafty crawl spaces. The original floor registers were never designed for modern variable-speed equipment. We replaced a 1958-era gas furnace in a Crestmoor Canyon home where the original uninsulated ductwork and undersized floor registers couldn’t handle modern variable-speed equipment. The homeowner’s heat pump coils had corroded from Gap winds, so we retrofitted with a coated Carrier unit and sealed the crawlspace ducts. Furnace replacement in San Bruno typically costs $3,500–$7,500, with complex retrofits at the higher end.
Furnace Tune-Up
Given San Bruno’s heating-dominant climate, annual tune-ups aren’t optional — they’re essential for systems running eight months or more per year. Our tune-up includes combustion analysis, heat exchanger inspection, and specific attention to salt-air corrosion on outdoor cabinets and vents. A standard furnace tune-up in San Bruno runs $80–$200. We recommend scheduling before October, when the first sustained marine-layer push typically arrives.
Heat Exchanger Repair & Replacement
Heat exchanger cracks are among the most serious failures we encounter in San Bruno, and they’re disproportionately common here. Decades of cycling in cold, foggy conditions stress metal fatigued by thermal expansion. Original furnaces in Rollingwood and Portola Highlands tract homes are particularly susceptible. A cracked heat exchanger can leak carbon monoxide, and we won’t patch-and-pray — we replace with proper documentation. Heat exchanger work in San Bruno typically runs $150–$700 for repairable issues, though full replacement often pushes toward furnace replacement territory.
Ignitor Replacement
Ignitor failure from moisture intrusion is a signature San Bruno problem. Persistent marine layer, especially in units with outdoor exhaust venting facing west, introduces humidity that shortens hot surface ignitor lifespan dramatically. We’ve replaced ignitors that failed in under two years due to Gap exposure. The fix isn’t just swapping the part — we evaluate venting direction and cabinet sealing to prevent repeat failures. Ignitor replacement in San Bruno typically costs $150–$700.
Gas Valve Repair
Gas valve corrosion from salt air affects outdoor-mounted furnaces and heat pump cabinets in ways that surprise homeowners relocating from drier climates. Inconsistent ignition, delayed lighting, or complete failure can all trace back to a corroded valve body or solenoid. We stock replacement valves for common San Bruno brands and can usually source same-day for others. Gas valve repair in San Bruno typically runs $150–$700.

Trusted Brands We Service in San Bruno
Your system, our specialty — that applies to Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We maintain local parts relationships that keep common components available for San Bruno customers without extended waits. For the older Goodman and Rheem units common in San Bruno’s post-war housing stock, we often have ignition modules, blower motors, and gas valves on the truck. Factory-trained compatibility across all nine brands means you’re never told “we don’t work on that.” From emergency calls to commercial buildouts, we have the technical range to handle whatever heating system your San Bruno property runs.
Common Heating & Furnace Problems We See in San Bruno Homes
- Heat exchanger cracks from decades of cold-weather cycling. Original furnaces in 1950s tract homes have cycled through 60+ San Bruno winters. Metal fatigue accumulates. We inspect with cameras and combustion analyzers, never guesswork.
- Ignitor failure accelerated by marine-layer moisture. West-facing venting gets hit hardest. Homeowners notice intermittent ignition or repeated lockouts on cool, foggy mornings.
- Gas valve corrosion from salt-air exposure. Outdoor cabinets and roof-mounted units in Gap-exposed neighborhoods show this pattern. The valve doesn’t fail all at once — it gets sticky, then unreliable, then dangerous.
- Ductwork mismatched to modern equipment. Original uninsulated runs in crawl spaces can’t deliver proper airflow for variable-speed furnaces. We see this in nearly every San Bruno replacement where the homeowner wants higher efficiency without duct modifications.
Pricing for Heating & Furnace in San Bruno, CA
Here’s what San Bruno homeowners actually pay for heating and furnace work. These ranges reflect our 19 years of pricing jobs across the Peninsula, calibrated for local part costs and labor conditions.
| Service | Typical Range in San Bruno |
|---|---|
| Furnace Repair | $150 – $700 |
| Furnace Replacement | $3,500 – $7,500 |
| Furnace Tune-Up | $80 – $200 |
| Heat Exchanger | $150 – $700 |
| Ignitor Replacement | $150 – $700 |
| Gas Valve Repair | $150 – $700 |
Several factors push costs higher or lower. Accessibility matters — furnaces in tight crawl spaces off Crestmoor Drive take longer than garage-mounted units near San Bruno Avenue. Ductwork modifications add labor and materials. And coated or marine-grade components, which we strongly recommend for Gap-exposed installations, carry a modest premium that pays back in extended lifespan.
We provide upfront pricing before any work begins. Estimates are free. Call (844) 560-6978 to schedule.

FAQs — Heating & Furnace in San Bruno
The San Bruno Gap funnels salt-laden Pacific marine air directly through the city, while San Mateo sits in a more sheltered position. This constant salt exposure corrodes outdoor heat pump coils, gas valves, and cabinet hardware in two to three years without protective coating, versus five to seven years in calmer inland locations. We specify coated components and directional venting for every San Bruno installation. Call (844) 560-6978 if you’re seeing premature corrosion — we can evaluate protective options.
Often no — and this is the most common misconception we encounter in San Bruno’s post-WWII neighborhoods. Original uninsulated ductwork and undersized floor registers can’t move the airflow modern variable-speed furnaces require. We evaluate static pressure and deliver airflow before recommending equipment. Sometimes sealing and partial duct modification suffices. Other times, full duct retrofit is necessary to achieve rated efficiency and avoid premature equipment failure. Call (844) 560-6978 for a free assessment of your specific system.
Moisture intrusion from persistent marine layer, particularly in units with west-facing exhaust venting, shortens hot surface ignitor lifespan by 30–50% compared to drier Peninsula locations. We see intermittent ignition and control lockouts spike during August and September fog seasons. Our repairs include evaluating venting direction and cabinet sealing, not just swapping the failed part. Call (844) 560-6978 for ignitor replacement — estimates are free.
The Gap’s cold, windy conditions actually favor heat pump heating efficiency — ambient temperatures rarely drop below the range where modern cold-climate heat pumps operate effectively. However, the same salt air that corrodes coils also fouls outdoor sensors and defrost controls. We specify coated coils and more frequent maintenance intervals for San Bruno heat pump installations. Call (844) 560-6978 to discuss whether a heat pump makes sense for your specific exposure and heating load.
For furnaces over 25 years old in San Bruno, replacement is usually the better investment — especially given the ductwork and efficiency gains available with modern equipment. A 60-year-old unit has exceeded any reasonable design lifespan, replacement parts are increasingly unavailable, and heat exchanger failure risk rises sharply. We provide honest repair-versus-replace guidance based on your specific unit condition, not sales pressure. Call (844) 560-6978 for a free evaluation and upfront pricing on both options.
Ready to get your San Bruno home’s heating system sorted? Whether you’re dealing with a failed ignitor in Crestmoor, a cracked heat exchanger in Rollingwood, or you’re finally ready to replace that original 1950s furnace, we’re here to help. Owner-managed, not outsourced — that’s how we’ve operated for 19 years. Call (844) 560-6978 for a free estimate. We’ll give you honest answers, specific pricing, and work that holds up to whatever the San Bruno Gap throws at it.
