Woodside isn’t like the flatland cities down the hill. Our crews have spent 16 years learning the difference. Jason Trent, our owner and Field Supervisor, has personally supervised furnace work on estates where the nearest neighbor is a quarter-mile away and the only heat source is a propane tank tucked against a redwood grove. That experience matters when your guest cottage’s radiant zone goes cold at 10 PM on a January night.
Why Stonegate Heating & Air California Is Woodside’s Preferred Heating & Furnace Company
We’ve earned 499 verified reviews at a 4.7-star average across our 16 years in business, and a growing share of those come from Woodside homeowners who found us after frustrating experiences with contractors unfamiliar with hillside propane systems. They mention the same things: Jason showed up, asked the right questions about tank location and defensible space, and didn’t treat their 1920s estate like a tract home in Redwood City.
Our response time to Woodside averages under 90 minutes for emergency calls, though we always clarify drive time from Sacramento-based dispatch. What saves time is that our trucks carry propane orifice kits, spark-arrestor flue caps, and the specialized ignition components that Woodside’s off-grid estates demand. A technician from Menlo Park might need to order parts. We don’t.
Local knowledge extends to the Town of Woodside’s permitting office and its WUI overlay requirements. We’ve navigated fire-code inspections for flue terminations, coordinated with propane suppliers on tank setback compliance, and retrofitted ductwork through hillside construction that would make a standard contractor decline the job.
Our Heating & Furnace Services in Woodside
Furnace Repair
Furnace repair in Woodside often involves problems you won’t find in a standard suburban service manual. We replaced a failing Carrier gas valve on a 1920s Tudor-revival estate off Portola Road, where the owner’s propane system required a special orifice kit and a spark-arrestor flue cap to meet the Town’s fire code. Our tech spent an extra hour routing the flue termination 10 feet from any wood-shingle eaves. That kind of precision is standard for us, not exceptional.
Common Woodside furnace failures include propane-to-natural-gas conversion errors on older retrofits. Wrong orifices produce yellow flames and sooting that can damage heat exchangers. We catch these during diagnosis because we know to check fuel type before touching the burner assembly.
Furnace Replacement
Replacing a furnace in Woodside means sizing for propane BTU ratings, selecting equipment compatible with existing radiant-hydronic zones, and ensuring WUI compliance for every penetration and termination. Many of the 1960s–80s ranch-style custom builds on Alpine Road and Mountain Wood Road have aging ductwork that must be retrofitted through difficult hillside construction, or no ductwork at all.
We specify American Standard and Trane systems with proven performance in cooler, damper foothill conditions, and we coordinate with local propane suppliers on tank capacity for the new load.
Furnace Tune-Up
A furnace tune-up in Woodside costs $80–$200 and includes checks that flatland contractors often skip. We inspect spark-arrestor flue caps for oak debris accumulation, test propane pressure at the regulator, and verify defensible-space clearances around outdoor components. The marine layer here keeps things damp year-round, so we pay special attention to corrosion on ignition modules and flame sensors.
Properties with multiple structures — main house, guest cottage, barn ADU — may need separate tune-ups for each system. We bundle these for efficiency.
Heat Exchanger Inspection & Repair
Heat exchanger failures in Woodside often trace back to years of propane combustion with improperly sized orifices, or restricted flue flow from clogged spark arrestors. A cracked exchanger is a carbon monoxide risk. We inspect with cameras and combustion analyzers, and if replacement is needed, we factor in the estate’s propane configuration and WUI flue requirements from the start.
Gas Valve Repair
Gas valve repair on propane systems demands different pressure specs and often different valve bodies than natural gas equivalents. We stock both. On a recent call near the Woodside-Purisima corridor, a failed valve had been replaced by a previous contractor with a natural-gas-rated unit that couldn’t maintain proper propane pressure. We diagnosed it in 20 minutes and had the right replacement on the truck.
Ignitor Replacement
Propane-fired furnaces use hotter ignitor specifications than natural gas units, and the damp Woodside climate accelerates silicon carbide degradation. We carry propane-rated ignitors for Carrier, Lennox, and Trane systems, and we check the entire ignition sequence rather than swapping parts blindly.

Trusted Brands We Service in Woodside
We’re experienced with nine major HVAC brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — which means we don’t turn away Woodside homeowners with less common equipment. Our trucks stock propane conversion kits, spark-arrestor caps, and ignition components for Carrier and Trane systems specifically, since those appear frequently in the 94062 zip code. When a part isn’t on the truck, our supplier relationships in the Peninsula area typically turn it around next-day. We’ve learned which Lennox models hold up best in damp foothill conditions, and which American Standard condensing furnaces tolerate the extended run times that Woodside’s cool climate demands.
Common Heating & Furnace Problems We See in Woodside Homes
- Propane conversion errors on retrofits. Older estate homes in Woodside sometimes had furnaces converted from oil or natural gas without proper propane orifice sizing. The result is incomplete combustion, sooting, and premature heat exchanger failure. We catch this during our first combustion analysis.
- Spark-arrestor flue caps clogged with oak debris. Woodside’s dense oak canopy drops leaves and acorns directly onto roof terminations. A blocked cap triggers rollout safety switches and shuts the furnace down hard. We clear and inspect these on every tune-up.
- Radiant-heat zones isolated by sagging hillside ductwork. Guest cottages and barn ADUs on Woodside’s slope properties often lose heat when flexible duct runs separate at joints or sag into standing water. We reroute with proper supports and sealed connections.
- Short-cycling from oversized equipment. Custom estates with great-room volumes and high ceilings sometimes have furnaces that cycle on and off too quickly, never reaching steady-state efficiency. We recalculate loads and adjust blower speeds or recommend right-sized replacement.

FAQs — Heating & Furnace in Woodside
Yes. The Town of Woodside’s WUI overlay requires fire-department inspection of propane tank setbacks, spark-arrestor flue terminations, and defensible-space clearances, separate from standard building permit review. We coordinate both permit tracks and schedule inspections so you’re not chasing paperwork between offices. Call (855) 467-1888 and we’ll walk you through the specific requirements for your property.
It’s possible but rarely straightforward. Many Woodside craftsman and Tudor-revival estates were built with radiant heat or no central system at all, and retrofitting ductwork through original plaster, hillside framing, and WUI fire-rated penetrations adds significant cost and complexity. We evaluate each home individually, sometimes recommending ductless mini-splits or hydronic retrofits as more practical paths. Call for a free assessment of your specific layout.
Condensing furnaces from Carrier and Trane with stainless steel heat exchangers handle extended run times and damp conditions well, and their propane conversion kits are readily available. We avoid equipment with aluminum exchangers in this climate due to corrosion risk. Our 16 years of California foothill experience informs every recommendation.
Yes. Spark-arrestor caps on Woodside’s oak-shaded properties clog regularly with leaves, acorns, and debris, restricting flue flow and triggering safety shutdowns. We check and clear these on every service call, and we can install higher-profile terminations where tree coverage is dense. If short-cycling persists after clearing, we’ll test the limit switch and combustion sequence. Call (855) 467-1888 for same-day diagnosis.
Woodside tune-ups include additional WUI compliance checks, propane system testing, and often longer drive times and access challenges for hillside estates. The $80–$200 range overlaps with Menlo Park for standard single-system homes but trends higher for multi-structure properties or those requiring spark-arrestor maintenance. We quote upfront before starting work, and estimates are free.
