Fast, Reliable Heating & Furnace Across North Fair Oaks

We’re Crestview Heating & Air California, and our Heating & Furnace team knows North Fair Oaks well. We’ve spent nearly two decades working on the exact systems found here: 1940s floor furnaces in the neighborhoods off Middlefield Road, wall heaters in the duplexes near Edison Way, and the occasional forced-air retrofit in the few newer builds closer to the Atherton border. North Fair Oaks sits in that tricky microclimate where summer afternoons spike into the 90s while winter nights drop into the 40s, so your heating system works hard half the year and your neighbors are increasingly adding cooling to homes that were never designed for it.
Because North Fair Oaks is unincorporated San Mateo County, not a city, every permit routes through the county building division in Redwood City. That’s a detail that catches less experienced contractors off guard. We’ve navigated those county inspections hundreds of times. Call us at (844) 560-6978 for a free estimate.
Why Crestview Heating & Air California Is North Fair Oaks’s Preferred Heating & Furnace Company
Our reputation here is built on showing up and solving problems that other companies walk away from. We’ve got a 4.8-star average across 250+ customer reviews, and a solid share of those come from North Fair Oaks homeowners who called us after a competitor said their system was “too old” or their crawlspace was “too tight” to run ductwork.
Owner Marcus Feldman still serves as our Service Manager, which means the person who answers your questions on the phone is the same person who’ll make sure the job gets done right. Not a dispatcher. Not a franchise script. We’ve been at this for 19 years, and we’ve worked on virtually every heating system type, age, and brand a North Fair Oaks home could have.
Our response time to North Fair Oaks is fast because we’re based in San Jose and know the back routes up 101 or Woodside Road without relying on GPS. When a floor furnace fails on a home off Fifth Avenue, we understand that “same day” often means “before the kids get home from school.”
We also know the local housing stock. These post-WWII homes on small, irregular lots weren’t built with central ductwork. Upgrading to a modern furnace isn’t just a swap. It’s a design challenge that requires fitting new ducts into tight attics or under low-clearance raised foundations, all while meeting county code. That’s where our experience shows.
Our Heating & Furnace Services in North Fair Oaks
Furnace Repair in North Fair Oaks
Furnace repair in North Fair Oaks runs $175–$825 depending on the part and the system’s age. Most calls we get here involve floor furnaces or wall heaters from the 1950s and 60s that have finally given out, or modern gas furnaces with failed ignitors and gas valves. The salt air from the coast accelerates corrosion on burners and heat exchangers, so we see premature failures even on systems that should have years left. We stock parts for Trane, Lennox, Goodman, and Rheem, and we carry universal components for the older units that manufacturers no longer support.
Furnace Replacement in North Fair Oaks
Replacing a furnace in North Fair Oaks is rarely straightforward. Most homes here were built without central ductwork, so a “furnace replacement” often becomes a full system design. We replaced a 1950s floor furnace with a new Trane gas furnace for a home on Edison Way, where the original wall heater had no ductwork. We ran new ducts through the low crawlspace, passed the county’s duct-leakage test, and installed a Bryant heat pump for cooling, giving the family whole-home comfort for the first time. That job required county permits, Title 24 compliance, and creative routing through a crawlspace with less than 18 inches of clearance. We handle that complexity regularly.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a serious safety issue we see constantly in North Fair Oaks’s original floor furnaces. These units from the 1940s–60s ran for decades with minimal maintenance, and the metal fatigues over time. A cracked exchanger can leak carbon monoxide into your living space. We use combustion analyzers and visual inspection cameras to check for cracks, and if we find one, we’ll show you the image and explain your options: repair if the part’s available, or replacement if the system’s too old to justify the cost. Given the age of housing stock here, replacement is often the smarter long-term choice.
Furnace Tune-Up in North Fair Oaks
A furnace tune-up in North Fair Oaks costs $95–$235 and includes burner cleaning, heat exchanger inspection, gas pressure testing, and safety control verification. For homes with original floor furnaces, we also check the floor grille seal and combustion air pathways, which are unique to these systems. Given the salt air corrosion we see here, we pay special attention to burner rust and heat exchanger deterioration. Annual tune-ups catch problems before they become emergency calls on the coldest night of the year.

For the older floor furnaces and wall heaters still common in this area, we source compatible components or recommend replacement when parts are obsolete. Your system, our specialty.
Common Heating & Furnace Problems We See in North Fair Oaks Homes
- Cracked heat exchangers in 1940s–60s floor furnaces. These units ran for 60+ years with minimal care, and the metal finally gives out. We find cracks during routine inspections that homeowners never suspected, and we treat every one as a potential CO hazard.
- No existing ductwork forcing costly, complex retrofits. Homes built with wall heaters or floor furnaces have no infrastructure for central air. Running new ducts through tight attics or low crawlspaces requires careful design, and shortcuts here lead to the undersized or leaky ducts we see botched by other contractors.
- Salt-air corrosion on burners and heat exchangers. North Fair Oaks’s position on the mid-Peninsula means coastal moisture reaches furnace components that inland communities never worry about. We see rusted burners fail years early and recommend corrosion-resistant materials when replacing systems.
- Failed county inspections due to skipped duct-leakage testing. Because North Fair Oaks is unincorporated, county inspectors enforce California Title 24 requirements strictly. Contractors who assume this “small neighborhood” won’t be scrutinized face failed inspections and costly re-work. We test before the inspector arrives.

FAQs — Heating & Furnace in North Fair Oaks
Yes, all furnace replacements in North Fair Oaks require a permit through the San Mateo County Building & Safety Division in Redwood City, since the community is unincorporated and has no municipal building department. We handle the permit application, scheduling, and inspection coordination as part of our standard replacement process. Call (844) 560-6978 and we’ll walk you through what’s needed for your specific job.
A rotten-egg smell from any gas heating system usually indicates a gas leak or, in older units, combustion byproducts escaping through a cracked heat exchanger. In North Fair Oaks’s original floor furnaces, decades of thermal cycling fatigue the metal until cracks form, allowing odorant-added gas or exhaust to enter living spaces. Shut the system off, open windows, and call us immediately at (844) 560-6978. This is not a DIY diagnosis.
Yes, we do this regularly in North Fair Oaks, though it requires designing and installing ductwork from scratch in homes that were never built for it. We route ducts through tight attics, low crawlspaces, or sometimes closet chases, all while meeting county Title 24 duct-leakage standards. The Edison Way project we completed is a typical example. Call for a free assessment of your home’s options.
Yes, San Mateo County enforces California Title 24 duct-leakage testing on all HVAC retrofits in unincorporated areas including North Fair Oaks. We test our own work before the inspector arrives to catch and fix any issues, which is why our jobs pass on the first inspection. Contractors who skip this step face failed inspections and costly re-work. Ask us about this during your estimate.
Trane and Rheem both offer corrosion-resistant cabinet and heat exchanger options that hold up well in coastal-influenced environments like North Fair Oaks. We also specify stainless hardware and coated components on our installations here, regardless of brand. The right specification matters as much as the brand name. Call (844) 560-6978 and we’ll recommend what fits your home and budget.
