A furnace that’s twenty years old and cycling oddly in a Portola Valley estate home is a different problem than the same furnace in a suburban tract house. Most homes here sit on multi-acre lots, many built from the 1950s through the 2000s, with detached guest houses and workshops that each run their own heating. Winters are mild, but the ductwork in a 1990s contemporary with large glazed areas has to be sized for rooms that lose heat fast when the sun drops behind the oaks. We handle full heating and cooling under one contractor, and furnace replacement is the call we take most in Portola Valley. Call (833) 573-8799 for a free estimate.
Why Portola Valley Homes Are Different
Portola Valley is a foothill town with strict rural and wooded-lot rules, and that shapes HVAC work before a technician touches a system. Wildfire defensible-space requirements mean outdoor equipment – condensers, furnace vents, anything with a flame or a compressor – has to be placed with brush clearance in mind. A unit tucked against a wooded lot edge can fail an inspection even if it runs perfectly. So equipment often moves closer to the house, screened behind fire-resistant enclosures, which is exactly where noise matters: near a bedroom wing with windows open on a warm evening.
The climate is an inland-facing foothill pattern: warm, dry summers and genuinely mild winters. Cooling loads are real. Heating loads are gentler than the numbers on a Bay Area spec sheet might suggest, so oversizing a furnace here wastes fuel and shortens the equipment’s life. Housing stock is mostly custom ranch and contemporary estates, many with multiple zones and separate structures, and ZIP code 94028 runs from wide-open meadow lots to narrow private drives where a service vehicle has to be scheduled carefully. All of that changes how we approach a replacement.

Our Main Portola Valley Services
Furnace replacement and AC installation are the two jobs Portola Valley homeowners call us about most, and both are handled by the same team.
AC Installation in Portola Valley
Installing cooling in a Portola Valley home usually starts with where the condenser can legally and quietly live. Defensible-space rules and narrow private drives push equipment placement toward the house, which puts a premium on variable-speed systems that run at low output and stay quiet near open windows. In a multi-acre estate with a detached guest house or workshop, each structure needs its own load calculation rather than a single oversized unit for everything. We size to the actual house, not to a rule of thumb. For the full scope, see AC Installation in Portola Valley.
Furnace Repair in Portola Valley
Repair calls here most often trace back to a furnace that was never quite right after a remodel added glazed square footage, or to a zoned system where one wing never heats evenly. Mild winters mean a failing furnace can limp along for a season before anyone notices, which is why we test ignition, heat exchanger, and airflow together rather than swapping a part and leaving. Goodman and Rheem systems are common in the older ranch homes. Details are on our Furnace Repair in Portola Valley page.
Furnace Replacement in Portola Valley
Furnace replacement in Portola Valley isn’t a like-for-like swap. Homes built from the 1950s through the 2000s were often heated by a single furnace sized for the original footprint, and decades of additions, glazed walls, and separate guest structures have outgrown that sizing. Mild winters hide the problem: a short-cycling furnace still takes the chill off, so nobody replaces it until the repair bills stack up. Our Furnace Replacement work starts with an honest load calculation for the house as it stands today, then a recommendation on whether a repair genuinely makes sense or the unit has earned retirement. We work across Goodman, Rheem, and York systems among others, so the recommendation follows the house, not a dealer incentive.
Right-Sizing and Zoning a Replacement Furnace
Signs you need it
A furnace that short-cycles on mild days, leaves one wing of the house cold, or is paired with a thermostat that never reaches its setpoint is telling you the sizing is wrong, not just the part.
What it costs in Portola Valley
Furnace replacement runs higher than a repair, and the typical installed range depends on the size and complexity of the house; the written estimate sets the final price.
How we do it
We measure the conditioned space room by room, account for added glazed areas and any detached structure on its own zone, then match equipment output and duct capacity to that number before ordering anything.
Replacing an Aging Furnace in an Estate or Ranch Home
Signs you need it
A furnace past its expected service life with rising repair frequency, a corroded heat exchanger, or a unit that no longer matches the rest of the system is a replacement candidate rather than a repair.
What it costs in Portola Valley
Cost tracks equipment tier and how much ductwork and venting has to be brought up to standard, and the written estimate sets the final price once we’ve seen the space.
How we do it
We pull the old unit, verify venting and clearances against current requirements, set the new furnace, reconnect and seal the duct connections, and commission it with a combustion and airflow check before we leave.

Can you replace a furnace in Portola Valley the same day?
No – replacement is load-calculated, ordered, and scheduled, not a same-day repair. We measure the house, order the right equipment, and set an install date. Call (833) 573-8799 for a free estimate and a firm price.
Do I need a permit to replace a furnace in Portola Valley?
Most jurisdictions require a permit for furnace replacement, so ask the town’s building department what applies to your property. We can work with the requirements and build the paperwork into the job. Call (833) 573-8799 to talk through your project.

What pushes price up in Portola Valley is usually the house, not the equipment: long private drives that slow a delivery, defensible-space placement that requires screening or relocation, and multi-zone estates where each detached structure needs its own system. We give you an upfront written price before any work starts, so the estimate is the number you pay.

What Portola Valley Customers Say
"Ductwork in the attic had a disconnected run that had been dumping cold air into the insulation for who knows how long. He found it, resealed it, and one bedroom that was always hot is now normal."
- Kurt Kowalski"Blower motor on a 12 year old furnace. He gave me the honest math on repair versus replace and did not push me toward the bigger ticket. We repaired it and it's been fine."
- Daniela Herrera"New system install, two days, and they were careful with the floors and the attic access the entire time. Registered the warranty for me and emailed the paperwork."
