Furnace Installation in Palo Alto

Most Palo Alto gas furnace installations run $4,500–$12,000, though Palo Alto’s stricter permitting process and larger homes often push costs toward the higher end, depending on furnace size, efficiency rating, and the condition of your existing ductwork — see our full furnace cost guide for a breakdown by system type. Air & Plumbing Systems (CSLB #901246) provides an exact, upfront quote for your gas furnace installation after a free in-home assessment — no guessing, no hidden fees.

Most single-family furnace installations in Palo Alto are completed in one day. Because CPAU permitting can take longer than a standard PG&E-territory permit, we build that into your timeline from the start — we’ll give you a clear schedule during your free assessment.

Rising gas bills, uneven heating between rooms, frequent repairs, a yellow burner flame, or a furnace 15+ years old are the top signs — especially common in Palo Alto’s older Eichler-era homes. A yellow flame or cracked heat exchanger is a safety issue — turn the furnace off and call us right away.

Yes — and Palo Alto has some of the strictest permitting requirements in the Bay Area, on top of the standard Title 24 (the state’s building energy-efficiency code) rules. We pull the permit and coordinate the inspection with the City of Palo Alto as part of every install, so you don’t have to navigate it yourself.

It depends on your home. A heat pump heats and cools with one system and, since Palo Alto runs its own utility, can qualify for CPAU’s “Electrify My Home” rebates when it replaces a gas furnace — plus a bonus if you remove the gas meter entirely. A gas furnace, on the other hand, tends to heat faster on Palo Alto’s coldest nights. The right choice comes down to your electrical panel, budget, and how the home is used — we’ll walk you through both options during your free assessment.

We offer same-day diagnostics for most Palo Alto service calls. The install itself is usually done the day after your free assessment, though CPAU permit timing can affect the overall schedule. Call (408) 733-2000 to get started.

In most cases, yes — reusing the existing location keeps ductwork, gas line, and venting connections simple and keeps costs down. Given Palo Alto’s stricter code enforcement, we double-check that the current setup still meets requirements; if it doesn’t, we’ll flag it during your free assessment and walk you through the options.

Furnace size depends on your home’s square footage, insulation, window count, and layout — not on floor area alone. Palo Alto’s older Eichler-era homes often have extensive glass, which changes the calculation. We run a Manual J load calculation during your free assessment so you get a furnace that’s sized correctly, not oversized or undersized.
