Palo Alto’s mild winters create a unique problem: furnaces sit unused for months, then fail catastrophically on the first cold night. We’ve spent 16 years tracking these failure patterns across the 94303, 94304, 94306, and 94309 ZIP codes. Jason Trent, our owner and active Field Supervisor, has personally diagnosed seized components in Greenmeadow Eichlers and restored heat to Crescent Park homes before dinner. That hands-on presence is why nearly 500 customers have left us a 4.7-star average — and why Palo Alto residents call us back.
Why Stonegate Heating & Air California Is Palo Alto’s Preferred Heating & Furnace Company
Our reputation in Palo Alto was built job by job, not through advertising. We show up. Jason Trent supervises every project in the field, not from a truck or back office. That matters when you’re explaining why a 1960s radiant slab can’t be patched again, or walking a homeowner through CPAU rebate paperwork that a less attentive contractor would mishandle.
Sixteen years and nearly 500 reviews tell the story better than we can. Those reviews come from real Palo Alto addresses — Matadero Avenue, Waverley Street, Middlefield Road — where we’ve replaced failed gas valves, retrofitted modulating furnaces into Eichler atriums, and cleared permit inspections that out-of-town contractors fumbled.
Response time to Palo Alto matters because heating failures here don’t follow business hours. The first cold snap of November hits, and dormant systems fail in clusters. We keep parts in stock for the nine brands we service, which means less waiting for a Carrier gas valve or a Trane ignitor. From our Sacramento base, we route technicians efficiently to Palo Alto and the foothills corridor, where 94304 temperatures can swing harder than the bay side.
Local knowledge separates competent technicians from the ones who waste your time. We know CPAU’s rebate programs differ entirely from PG&E’s. We know Eichler flat roofs and open-beam ceilings demand ductless solutions. We know which Palo Alto neighborhoods have original 1950s copper radiant pipes embedded in crumbling concrete. That specificity saves hours on every job.
Our Heating & Furnace Services in Palo Alto
Furnace Repair
Furnace repair in Palo Alto runs $150–$700, depending on whether we’re replacing a failed ignitor or rebuilding a gas valve assembly. The most common call we get: the system worked fine last winter, sat silent through five mild months, and now won’t fire. In a Greenmeadow Eichler on Matadero Avenue, we diagnosed a seized inducer motor on a 1965 Lennox furnace that had sat dormant through five mild months. The original 24V gas valve was also failing, so we retrofitted a modulating Carrier furnace and integrated a ductless mini-split for cooling — matching the flat roofline and open-beam ceiling without ductwork. We stock parts for Carrier, Trane, Lennox, and the other six brands we cover, so most Palo Alto repairs don’t wait on shipping.
Furnace Replacement
When repair costs approach half the value of a new system, we recommend replacement. In Palo Alto, this decision often intersects with unique housing constraints. Eichler homes in Fairmeadow and Greenmeadow have no ductwork and post-tension concrete slabs — forcing air through walls isn’t an option. We’ve replaced dozens of aging radiant systems with high-efficiency modulating furnaces paired to ductless mini-splits, preserving the architectural integrity while delivering modern comfort. For older California ranches in Crescent Park or the California Avenue area, standard forced-air replacement is straightforward, and we size systems to the actual load — not the rule-of-thumb calculation that oversizes and short-cycles. CPAU offers heat pump rebates that differ from PG&E’s programs; we file the paperwork correctly the first time.
Furnace Tune-Up
A furnace tune-up in Palo Alto costs $80–$200 and prevents the dormant-season failures that plague this market. Our tune-up covers heat exchanger inspection, gas valve testing, ignitor resistance check, and combustion analysis. Given Palo Alto’s mild Mediterranean climate, extended idle periods cause cracked heat exchangers and seized components that only reveal themselves during the first cold snap. We recommend scheduling before October, before the rush hits. For homes in the warmer 94304 foothills corridor, where cooling loads have driven more dual-fuel installations, we also verify heat pump switching logic.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a safety issue we take seriously. In Palo Alto’s Eichler stock, furnaces often sit in utility closets or garage-adjacent spaces, with limited ventilation — a cracked exchanger risks carbon monoxide infiltration. We inspect with visual borescope and combustion analysis, not a flashlight glance. Replacement requires exact matching to furnace spec; we source OEM heat exchangers for Carrier, Trane, Lennox, and our other supported brands. If the furnace is past 15 years and the exchanger has failed, we’ll show you the numbers on replacement versus repair.

Trusted Brands We Service in Palo Alto
We carry factory training or deep field experience on nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Palo Alto customers, this means no “we don’t service that brand” dead end. We stock common parts locally for Carrier, Trane, and Lennox — the three brands we see most often in Palo Alto’s mid-century and newer construction. American Standard components arrive within 24 hours when needed. Whether your furnace is a 2023 variable-speed Trane or a 1965 Lennox holding on in a Fairmeadow Eichler, we’ve worked on it. That breadth eliminates the contractor shuffle that frustrates homeowners who just want heat restored.
Common Heating & Furnace Problems We See in Palo Alto Homes
- Cracked heat exchangers after long dormancy. Palo Alto’s mild winters mean furnaces sit idle for months. The first cold snap in November or December triggers thermal stress on heat exchangers that have been expanding and contracting unchecked. We find this especially in Eichler slab homes where the original furnace has been patched past its service life.
- Seized inducer motors and failing gas valves. Extended mild stretches allow lubricants to settle and seals to dry. When the thermostat finally calls for heat, the inducer won’t spin or the 24V gas valve won’t open. We’ve replaced dozens in Greenmeadow and Old Palo Alto homes where the furnace simply “forgot” how to start.
- Failed ignitors in aging systems. Hot surface ignitors degrade with thermal cycling, but Palo Alto’s intermittent use accelerates the pattern — full heat one week, nothing for six. By year twelve, most ignitors are running on borrowed time. We check resistance and amp draw during tune-ups to catch this before failure.
- Slab-leak radiant system failures in Eichlers. Original copper pipes embedded in 1950s–60s concrete are corroding through. There’s no repair that lasts. We walk homeowners through forced-air or ductless alternatives, sized to the home’s actual load and designed around flat rooflines and open-beam ceilings.

FAQs — Heating & Furnace in Palo Alto
Yes. City of Palo Alto Utilities operates its own electrification incentive programs separate from PG&E, including rebates for heat pump water heaters and HVAC systems that many contractors miss by defaulting to PG&E assumptions. We file CPAU rebate paperwork as part of our installation workflow, not as an afterthought. Call (855) 467-1888 to confirm current rebate amounts for your specific project.
Yes, but it requires ductless or carefully designed mini-split distribution because Eichlers have zero ductwork and post-tension slabs that can’t be cut. We’ve retrofitted dozens of Fairmeadow and Greenmeadow Eichlers with modulating furnaces paired to ductless heads, preserving open-beam ceilings and flat rooflines. The solution depends on your specific floor plan and CPAU electrical service. Call (855) 467-1888 for a free assessment.
Palo Alto’s mild Mediterranean climate lets heating systems sit dormant for five to seven months, causing lubricants to settle, seals to dry, and heat exchangers to crack from thermal shock when finally called upon. The first cold snap of November produces a predictable wave of failure calls. A fall tune-up catches these issues before they leave you cold. Schedule at (855) 467-1888.
We service nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common parts for Carrier, Trane, and Lennox locally, and can source American Standard components within 24 hours. Whatever brand you have, we’ve likely repaired it in a Palo Alto home. Call (855) 467-1888 with your model number.
Yes. Palo Alto requires permits for furnace replacement, and inspections go through the city’s Development Center, not county channels. CPAU also requires electrical inspection for heat pump installations. Contractors unfamiliar with Palo Alto’s municipal structure often misfile or miss rebate tie-ins. We handle permits and inspections as standard on every replacement. Call (855) 467-1888 to discuss your project timeline.
