We’ve been working on San Jose heating systems for nearly two decades, and there’s not much we haven’t seen in this market. The city’s housing stock tells a unique story — tens of thousands of homes built during the 1950s–1970s suburban boom were fitted with only a single floor furnace or wall heater, no ductwork, no returns, no cooling infrastructure at all. That legacy shapes what we do differently here than in Sacramento or the East Bay. Our Heating & Furnace team knows which Cambrian Park subdivisions have bare joists above those old floor furnaces, which Berryessa tracts got basic forced-air in the 1980s, and where a “simple repair” quote turns into a full redesign because the original system was never meant to carry air conditioning.
Marcus Feldman, our owner and active Service Manager, still runs calls personally when the job demands it. That ownership-level accountability means the person quoting your job is the same person ensuring it’s done right — not a dispatcher reading from a script.
Why Crestview Heating & Air California Is San Jose’s Preferred Heating & Furnace Company
Our reputation in San Jose is built on showing up prepared for what this city’s older homes actually require. We’ve earned a 4.8-star average across 250+ customer reviews, and a significant share of those come from repeat clients in neighborhoods like Almaden Valley, Willow Glen, and the East Foothills who’ve learned we don’t underestimate the quirks of legacy systems.
Response time matters when your furnace fails during a Diablo wind event in October and temperatures spike past 100°F while your system is already stressed. We’re based in San Jose and route directly to your neighborhood without crossing county lines or sitting in Bay Bridge traffic. Most San Jose calls reach us within the hour, and emergency service is available when systems fail outside normal hours — no voicemail black hole, no third-party answering service making promises they can’t keep.
The local knowledge that separates accurate bids from expensive surprises? Knowing by address and construction decade whether your home has a plenum, trunk lines, or bare floor joists above that original furnace. We’ve lost count of how many “add AC to existing heat” jobs we’ve quoted in Cambrian Park that turned out to need complete ductless design because the house was built with a 1962 floor furnace and nothing else. That expertise saves San Jose homeowners from change-order disasters and mid-project redesigns.
Our Heating & Furnace Services in San Jose
Furnace Repair
Most San Jose furnace repairs we handle run $175–$825 depending on the component and accessibility. In older tract homes near Communications Hill and Alum Rock, we regularly find gas valve failures in wall heaters and cracked ignitor modules in 1980s forced-air units where replacement parts are getting scarce. We stock common components for Trane, Lennox, Goodman, and Rheem systems to complete same-day repairs when possible, and we’ll tell you honestly when a part is obsolete and replacement makes more sense than chasing a discontinued module.
Furnace Replacement
Replacing a furnace in San Jose’s legacy housing requires more than swapping boxes. Many homes in Cambrian, Berryessa, and the East Foothills were built with floor furnaces or wall heaters that have no duct infrastructure, no returns, and sometimes no safe path to add either. We recently serviced a 1960s tract home in Cambrian Park where the owner’s original floor furnace had developed a cracked heat exchanger. With no existing ductwork and a layout that made traditional forced-air impossible, we recommended a ductless mini-split system with multiple wall-mounted heads. The homeowner avoided a costly full-duct retrofit and now has zoned heating and cooling for under $5,000. That’s the kind of San Jose-specific solution you get from a team that knows this housing stock intimately.
Furnace Tune-Up
Our furnace tune-ups in San Jose run $95–$235 and focus on what fails here: heat exchanger integrity in aging floor furnaces, gas valve and pilot orifice cleaning before Diablo wind season, and combustion safety checks in homes where the original venting may not meet current standards. We recommend fall service before those hot, dry offshore wind events stress systems that haven’t run hard since February. A tuned furnace is also an efficient one — important in San Jose where Pacific Gas & Electric rates keep climbing and Title 24 compliance matters for any future sale or renovation.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are among the most serious safety issues we find in San Jose’s older homes, particularly in original floor furnaces still running in Cambrian and Berryessa. Carbon monoxide risk makes this non-negotiable: if we find a crack, we red-tag the unit and walk you through replacement options immediately. In some cases, the heat exchanger itself can be replaced; in others, the furnace is so old that the manufacturer no longer supports the part, and full replacement becomes the only viable path. We’ll show you the crack with a camera, explain your options without pressure, and quote both repair and replacement scenarios so you can decide based on real numbers.
Gas Valve Repair
Gas valve failures spike in San Jose during and after Diablo wind events, when dust and debris clog pilot orifices and cause intermittent ignition or complete failure to light. We’ve responded to dozens of these calls in Alum Rock and East Foothills tracts where wall heaters and older furnaces sit idle through summer, then fail to fire when first needed in fall. Sometimes it’s a cleaning and adjustment; sometimes the valve itself has failed from age and corrosion. We’ll diagnose it honestly and repair or replace based on what your specific unit needs, not what pads our invoice.

Trusted Brands We Service in San Jose
Your system, our specialty — that means we don’t turn away jobs because of the logo on the cabinet. Our technicians are factory-trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, and we stock common parts for the brands most prevalent in San Jose’s housing stock. Goodman and Rheem units were popular in 1980s–1990s tract builds across Willow Glen and Almaden Valley; Trane and Lennox appear more frequently in tech-era renovations and commercial spaces near downtown. We maintain local supplier relationships to minimize wait times on parts that aren’t on our trucks, because a San Jose homeowner without heat doesn’t care about our supply chain — they care about getting warm tonight.
Common Heating & Furnace Problems We See in San Jose Homes
- Cracked heat exchangers in original floor furnaces. Cambrian Park and Berryessa homes with 1960s-era floor furnaces regularly present this failure. The steel fatigues after 50+ years of thermal cycling, and replacement heat exchangers are often obsolete. We camera-inspect every older unit we touch.
- Gas valve and pilot failure during Diablo wind season. Those hot, dry offshore flows that hit San Jose in September and October carry dust that clogs pilot orifices and causes gas valves to stick. We see this annually in wall heater-dependent homes near Alum Rock and the East Foothills.
- Obsolete ignitor modules in 1980s forced-air furnaces. The spark ignition modules in early forced-air systems from that era are increasingly unsupported by manufacturers. We source rebuilt and aftermarket options when available, but often counsel replacement when the part hunt exceeds the unit’s remaining value.
- “No heat” calls that reveal no ductwork exists. San Jose’s 1950s–1970s tract homes were built with floor furnaces or wall heaters and zero air distribution infrastructure. Homeowners calling for “furnace repair” sometimes learn they have a heating appliance, not a forced-air system, and that any future cooling or whole-house comfort requires a fundamentally different approach.
Pricing for Heating & Furnace in San Jose, CA
Here’s what San Jose homeowners actually pay for heating service in this market:
| Service | Typical Range in San Jose |
|---|---|
| Furnace Repair | $175 – $825 |
| Furnace Tune-Up | $95 – $235 |
Where you land in these ranges depends on the component failed, the age of your system, and whether parts are still manufactured. A gas valve replacement on a 1995 Rheem with standard connections runs toward the lower end. A heat exchanger replacement quote on a 1962 floor furnace where the part is obsolete — that’s a replacement conversation, not a repair, and we’ll tell you so upfront. We don’t quote repairs we know won’t last.
Every estimate we provide in San Jose is free and itemized. You’ll know the part cost, labor hours, and total before we start. Call (844) 560-6978 to schedule yours.

FAQs — Heating & Furnace in San Jose
No — floor furnaces have no ductwork, plenum, or air handler, so there’s no distribution system for cooled air to travel through. In San Jose’s 1950s–1970s tract homes, adding central AC to a floor furnace setup requires either installing complete ductwork (often $8,000–$15,000+ in tight crawl spaces) or switching to a ductless mini-split system that provides both heating and cooling without ducts. We’ve completed dozens of these retrofits in Cambrian and Berryessa, and we’ll assess your specific layout for the most practical path. Call (844) 560-6978 for a free evaluation of your home.
Standard furnace replacement in San Jose runs roughly $2,500–$5,500 for equipment and installation, but legacy homes with floor furnaces or wall heaters often need additional work. If your home has no ductwork, a ductless mini-split with heating capability typically starts around $3,500 for a single-zone system and scales with the number of rooms. We itemize every quote so you see where the money goes, and we’ll compare repair-versus-replace scenarios honestly. For an exact number on your specific home, call (844) 560-6978 — estimates are free.
Diablo winds are hot, dry offshore flows that push into the Santa Clara Valley each fall, often spiking San Jose temperatures past 100°F in September and October. The same wind carries dust and debris that clogs pilot orifices and causes gas valves to stick in wall heaters and older furnaces that haven’t run since spring. We see a predictable surge of these calls in Alum Rock and East Foothills tracts within 48 hours of the first strong Diablo event. Annual fall maintenance before wind season arrives prevents most of these failures.
For furnaces past 30 years, replacement is usually the better investment unless the repair is minor and the heat exchanger tests sound. At 40 years, replacement parts are often obsolete, efficiency is far below modern standards, and safety risks escalate — especially with cracked heat exchangers that can leak carbon monoxide. We’ll show you the actual condition of your unit, quote both repair and replacement, and let the math guide the decision. If you’re in a San Jose tract home with no ductwork, we’ll also explain ductless options that solve heating and cooling together. Call (844) 560-6978 to schedule an honest assessment.
Yes — the City of San Jose requires permits for furnace replacement, and the work must pass inspection to ensure compliance with current mechanical and combustion safety codes. This is particularly important in older homes where original venting may not meet modern standards. We handle permit submission and scheduling as part of our installation process, so you’re not navigating city departments yourself. The permit cost is typically included in our quoted price, and we’ll coordinate inspection timing to minimize disruption. Call (844) 560-6978 and we’ll walk you through what your specific project requires.
