Fast, Reliable Heating & Furnace Across Hillsborough
Furnace repair in Hillsborough typically runs $150–$700 for most common issues, while a full furnace replacement costs $3,500–$7,500 depending on your home’s size and the complexity of retrofitting into older construction. We’re Crestview Heating & Air California, and our Heating & Furnace team regularly makes the short trip up from San Jose to Hillsborough for everything from emergency heat exchanger repairs to complete system replacements in historic estates. With nearly two decades of HVAC experience, we’ve learned that Hillsborough’s large custom homes built between the 1920s and 1960s present challenges you simply don’t see in standard suburban construction. Original gravity furnaces, fragile plaster walls, and the Town of Hillsborough’s strict design-review requirements mean you need a technician who understands the difference between a quick fix and a proper retrofit. Call us at (844) 560-6978 for a free estimate, and we’ll send an owner-managed crew who knows how to work with Hillsborough’s unique housing stock.
Why Crestview Heating & Air California Is Hillsborough’s Preferred Heating & Furnace Company
We’ve built our reputation in Hillsborough one careful retrofit at a time. Our 4.8-star average across 250+ customer reviews includes scores of Peninsula homeowners who needed more than a standard swap-out. They needed someone who could navigate a multi-zone installation in a 1930s Tudor without destroying irreplaceable lath-and-plaster details.
Owner Marcus Feldman serves as our Service Manager, which means he personally reviews Hillsborough jobs that involve design-review coordination or complex zoning. You’re not getting a dispatcher reading from a script. You’re getting a technician with 19 years in the field who still manages jobs directly.
Response time to Hillsborough matters when your furnace fails during a January cold snap. We’re positioned in San Jose with direct routes up 280 and El Camino Real, so we can typically reach Hillsborough properties same day for emergency calls. We’ve worked on homes from the lower Hayne Road corridor up to the hillside properties near Crystal Springs Road, and we understand the elevation-driven temperature variations that affect load calculations in this town.
The local knowledge that separates us: we know to site condenser units in walled mechanical courts or behind mature landscaping before filing permits, because Hillsborough’s building department will flag any equipment visible from the street. We bring this expertise so you don’t learn it the hard way during a design-review hearing.
Our Heating & Furnace Services in Hillsborough
Furnace Repair
Furnace repair in Hillsborough often means diagnosing problems in systems that are 40, 60, sometimes 80 years old. Original gravity furnaces develop heat exchanger cracks from decades of thermal cycling. That’s not just an efficiency problem; it’s a carbon monoxide risk that requires immediate attention. We also see failed ignitors, faulty gas valves, and blower motor burnout in aging systems throughout the 94010 ZIP code. Because parts availability for legacy equipment is increasingly limited, we’ll give you an honest assessment: whether repair makes sense for another season, or whether you’re throwing money at a system that’s past reliable recovery. Our furnace repair pricing in Hillsborough runs $150–$700 for the majority of calls.
Furnace Replacement
Replacing a furnace in Hillsborough is rarely straightforward. Many homes here never had forced-air ductwork; they relied on gravity warm-air or hydronic radiant systems. Installing a modern high-efficiency furnace means either designing a ducted system that preserves your plaster walls, or specifying a ductless multi-zone configuration. We recently retrofitted a 1940s estate on upper Crystal Springs Road where the original gravity furnace had finally failed. The homeowners wanted a high-efficiency gas furnace, but the plaster walls were too fragile to run new ductwork traditionally, so we designed a multi-zone system with ducted units in the attic and a concealed condensing unit behind a new brick wall. The town’s noise study was required because the new unit was within 50 feet of the property line. This is the kind of project where owner-managed execution matters. Our furnace replacement pricing in Hillsborough ranges from $3,500–$7,500.
Furnace Tune-Up
A furnace tune-up in Hillsborough should happen annually, even though our Bayside microclimate feels temperate compared to inland Bay Area cities. Here’s why: Hillsborough’s hillside terrain creates significant temperature variation. Homes higher on Crystal Springs Road or along the upper Hayne Road corridor can run 5–8°F cooler on winter evenings than properties closer to El Camino Real. That means your furnace works harder than you might assume, especially in drafty older construction with minimal original insulation. Our tune-up covers heat exchanger inspection, burner cleaning, gas pressure verification, and safety control testing. Catching a cracked heat exchanger early can prevent a full emergency replacement. Furnace tune-ups in Hillsborough cost $80–$200.
Heat Exchanger Inspection & Replacement
Heat exchanger failure is the most serious problem we encounter in Hillsborough’s older furnaces. Decades of expansion and contraction eventually create cracks that allow combustion gases to mix with your home’s air. We use visual inspection, combustion analysis, and when needed, borescope examination to assess heat exchanger integrity. In many Hillsborough homes with original gravity furnaces, the heat exchanger is integrated into a system that no longer has replacement parts available. When that’s the case, we’ll explain your options clearly: a modern replacement with proper zoning, designed around your home’s architectural constraints and the town’s design-review requirements.

Trusted Brands We Service in Hillsborough
Your system, our specialty. We maintain factory-trained compatibility across nine major HVAC brands, and for Hillsborough customers we regularly work with Trane, Lennox, Goodman, and Rheem equipment. These manufacturers offer the multi-zone, high-efficiency systems that suit large custom estates with complex heating loads. We stock common parts locally and coordinate with regional distributors for same-day or next-day availability on specialized components. Whether you have a 15-year-old Rheem that needs a gas valve, or you’re specifying a new Lennox multi-zone system for a complete retrofit, we won’t tell you “we don’t work on that.” From emergency calls to commercial buildouts, our brand coverage means one call handles your job.
Common Heating & Furnace Problems We See in Hillsborough Homes
- Original gravity furnace heat exchanger cracks. Decades of thermal cycling in Hillsborough’s 1920s–1950s estates eventually crack these massive cast-iron or welded-steel heat exchangers. The resulting carbon monoxide risk means complete system replacement is the only safe option, and we coordinate the transition to modern forced-air or ductless multi-zone heating.
- Legacy hydronic radiator corrosion and pinhole leaks. Many Hillsborough homes used early hydronic radiant systems with cast-iron radiators. Replacement parts are simply no longer manufactured. When leaks develop, homeowners face a decision: patch temporarily, or convert to forced-air with careful duct routing that avoids damaging ornate plaster.
- Plaster wall damage during retrofit attempts. Hillsborough’s thick, original plaster walls crumble easily when contractors rush ductwork installation. We’ve seen other companies create thousands in plaster repair bills that could have been avoided with attic-based duct routing or ductless mini-split design. We coordinate with architectural preservation specialists when wall penetration is unavoidable.
- Design-review delays from improperly sited condenser units. Hillsborough’s strict aesthetic standards mean a condenser visible from the street can trigger a design-review hearing. Experienced local contractors site equipment in walled mechanical courts or behind dense plantings before pulling the permit, not after. We build this into our project planning from day one.
Pricing for Heating & Furnace in Hillsborough, CA

| Furnace Replacement | $3,500 – $7,500 |
| Furnace Tune-Up | $80 – $200 |
What moves you within these ranges? System age and accessibility matter. A simple ignitor replacement on a 1990s furnace in a clean basement hits the lower end. A full multi-zone replacement in a 1930s estate with attic duct routing, design-review coordination, and concealed condenser siting runs toward the upper end. We provide written estimates before any work begins, and our estimates are free. Call (844) 560-6978 to schedule yours.

FAQs — Heating & Furnace in Hillsborough
We can often service original floor furnaces for basic repairs like thermocouple replacement or gas valve adjustment, but replacement parts are increasingly unavailable and heat exchanger cracks in these systems are common after 80+ years of use. When we inspect your unit, we’ll test the heat exchanger integrity and give you an honest assessment of whether another season of reliable operation is realistic. If replacement is the safer option, we’ll design a modern system that respects your home’s architecture and Hillsborough’s design-review requirements. Call (844) 560-6978 for a free evaluation.
You have several viable paths, and we’ve navigated all of them. The most common solution is relocating the condenser to a walled mechanical court or behind dense evergreen screening that satisfies the town’s visual screening requirements before permit issuance. In tighter setbacks, we sometimes specify quieter equipment that meets noise-study thresholds, or we design a ductless system with smaller outdoor units that are easier to conceal. Our project planning always includes a site visit to identify the optimal equipment location before any paperwork is filed. Call us at (844) 560-6978 and we’ll survey your property for compliant placement options.
It doesn’t have to. The key is duct routing that avoids wall penetration wherever possible. In many Hillsborough homes, we design attic-based duct systems with ceiling diffusers, or we specify ductless mini-split zones that require only a small refrigerant line through an exterior wall. When wall penetration is unavoidable for certain architectural configurations, we coordinate with plaster restoration specialists who understand historic lath-and-plaster techniques. Our 1940s Crystal Springs Road project used attic ducting exclusively for this reason. We’ll examine your home’s structure and present options that preserve its character. Call (844) 560-6978 to discuss your specific layout.
For large custom homes with complex zoning needs, we typically lean toward Trane and Lennox for their multi-stage, variable-speed systems that integrate cleanly with zone dampers and smart thermostats. Rheem also offers strong options for high-efficiency modulating furnaces that pair well with ducted multi-zone configurations. The right specification depends on your home’s square footage, wing layout, and whether we’re retrofitting into existing construction or working with new build parameters. We service all nine major brands, so our recommendation is based on your specific situation, not on what we happen to sell. Call (844) 560-6978 and Marcus will walk through the options with you directly.
Annual tune-ups are still the right interval for Hillsborough homes. While our Bayside microclimate is milder than inland areas, the elevation variation in Hillsborough means hillside properties on Crystal Springs Road or upper Hayne Road can experience significantly cooler winter temperatures than homes near El Camino Real. Older homes with minimal insulation and original windows lose heat faster than owners expect. More importantly, gravity furnaces and early forced-air systems common here develop heat exchanger cracks and combustion issues that annual inspection catches before they become safety hazards. Our tune-up is $80–$200 and includes written documentation of heat exchanger condition. Call (844) 560-6978 to schedule before the heating season peaks.
