Furnace Installation in Menlo Park

Most Menlo Park gas furnace installations run $4,500–$12,000, 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 Menlo Park are completed in one day. Because many Menlo Park Eichler homes have original, undersized ductwork, jobs that also require duct repair or replacement may take a bit longer — we’ll give you a clear timeline 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 Menlo Park’s Eichler-era homes. A yellow flame or cracked heat exchanger is a safety issue — turn the furnace off and call us right away.

Yes. The City of Menlo Park requires a permit for furnace replacement, and the install must meet Title 24 (the state’s building energy-efficiency code). We pull the permit and coordinate the inspection with the city as part of every install.

It depends on your home. A heat pump heats and cools with one system and, as part of San Mateo County, can qualify for Peninsula Clean Energy (PCE) rebates when it replaces a gas furnace. A gas furnace, on the other hand, tends to heat faster on Menlo Park’s coolest, coastal-influenced nights. In many Menlo Park Eichler homes, the deciding factor is electrical panel capacity — we’ll walk you through both options during your free assessment.

We offer same-day diagnostics for most Menlo Park service calls, with most single-family furnace installs completed the day after your free assessment. 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. In Menlo Park’s Eichler homes specifically, we check that the original layout can still handle a modern system’s airflow needs; if it can’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. Menlo Park’s Eichler homes often have extensive glass and open floor plans, 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.
