Which Heating System Is Right for Your Home?
Wondering how much it costs to install a furnace, or whether a furnace is even the right call for your home? Here’s how a new furnace installation compares to the other heating options available in California
Gas Furnaces
- Forced-air heating, most common system in Bay Area homes
- Runs on natural gas, heats fast even on cold nights
- 80–98% AFUE efficiency depending on model
Heat Pumps
- All-electric, heats and cools with one system
- Rebate-eligible when replacing a gas furnace
- Best fit for moderate Bay Area winters
Ductless Mini-Splits
- No ductwork required — wall-mounted indoor units
- Independent zone control room by room
- Popular in Eichler-era and older Bay Area homes
Dual-Fuel Systems
- Furnace and heat pump paired in one system
- Heat pump runs most of the year, furnace kicks in on the coldest nights
- Balances efficiency with reliable backup heat
Not Sure Which Fits Your Home?
Rebates May Be Available
Several Bay Area utilities offer rebates on qualifying heating upgrades, including heat pumps that replace gas furnaces. Rebate amounts and eligibility can change throughout the year, so check the latest available programs and requirements before starting your project.

FAQs
Most Bay Area 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 are completed in one day. Jobs that also require ductwork 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 an age of 15+ years are the top signs. A yellow flame or cracked heat exchanger is a safety issue — turn the furnace off and call us right away.
Yes. California requires a permit for furnace replacement, and it must meet Title 24 (the state’s building energy-efficiency code). We pull the permit and coordinate the inspection as part of every install.
It depends on your home. A heat pump heats and cools with one system and can qualify for Bay Area utility rebates, while a gas furnace tends to heat faster on the 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 calls across the Bay Area, 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. If your current setup doesn’t meet current code or airflow needs, 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. We run a Manual J load calculation during your free assessment so you get a furnace that’s sized correctly, not oversized or undersized.
