Furnace Installation in the Bay Area
High-efficiency gas furnace installation with transparent, all-inclusive pricing. Permits always included. Replace your old furnace in one day with zero surprises.
Gas Furnace Installation Cost in the Bay Area
A gas furnace replacement in the Bay Area costs $5,500–$13,000 installed, including equipment, labor, and permits. The biggest variables are AFUE efficiency rating, BTU output, and whether the installation requires new flue venting or gas line work.
Most Bay Area homes use 60,000–100,000 BTU furnaces. Inland areas like Livermore, Walnut Creek, Danville, Pleasanton, Brentwood, and Antioch benefit most from higher-efficiency 96% AFUE systems due to colder winters. Coastal communities can often stick with an 80% AFUE unit and save upfront cost.
Bundling a Furnace + AC installation saves on labor and qualifies for our $3,000 seasonal discount. Both systems are properly matched, installed in one visit, and covered under a single warranty.

Factors That Affect Furnace Installation Cost
- AFUE Efficiency: 80% AFUE is standard and affordable; 96–98% AFUE costs more upfront but saves $200–$500/year in gas bills in colder inland areas.
- BTU Output: Undersized furnaces run constantly; oversized ones short-cycle. We calculate the right size based on your home's square footage, insulation, and climate zone.
- Flue Venting: High-efficiency 96%+ furnaces use PVC flue pipes instead of metal. If your home needs new venting routed, this adds $300–$700.
- Gas Line: If a new branch, pressure regulator, or gas shutoff is needed, add $300–$800.
- Electrical Panel: If panel upgrade needed (200A), adds $3,000+.
- Permits: $975–$1,675 depending on city. Always included in your final quote.

Furnace Installation FAQs
How much does furnace installation cost in the Bay Area?
A gas furnace replacement in the Bay Area typically costs $5,500–$13,000 installed, depending on the brand, AFUE efficiency rating, and BTU size. An 80% AFUE single-stage furnace starts around $5,500; a premium 98% AFUE variable-speed furnace can reach $12,000–$13,000. Adding a new AC at the same time qualifies for our $3,000 seasonal discount.
What AFUE rating should I choose for a Bay Area home?
For most Bay Area homes, an 80% AFUE furnace is cost-effective because heating seasons are mild. In colder inland areas like Livermore, Walnut Creek, or Brentwood — where you run heat 4–6 months a year — upgrading to 96% AFUE saves $200–$400 per year on gas bills and often pays back within 5–7 years. We'll recommend the right tier for your specific climate zone.
Do I need a permit to replace my furnace in the Bay Area?
Yes. A furnace replacement always requires a mechanical permit and city inspection in every Bay Area jurisdiction. We handle all permitting and schedule the city inspection on your behalf. Permit fees ($975–$1,675 depending on city) are always included in your final quoted price — no surprise charges after the job.
How long does furnace installation take?
A standard furnace replacement takes 4–6 hours for a single technician team. If ductwork modifications, new flue venting, or gas line work is needed, the job may extend to a full day. We do everything in one visit whenever possible so your home isn't without heat overnight.
Should I replace my furnace and AC at the same time?
If your AC is more than 10–12 years old and you're replacing the furnace, replacing both at the same time is almost always worth it. You save on labor (one mobilization instead of two), the systems are matched for efficiency, and our $3,000 seasonal discount applies when you bundle a Furnace + AC installation.
Can I switch from a natural gas furnace to a heat pump?
Absolutely — this is one of the most popular upgrades we do in the Bay Area right now. A heat pump provides both heating and cooling from one system, with 2–3× the efficiency of burning gas. The Bay Area's mild climate makes heat pumps especially effective. We can also do a dual fuel system (heat pump + gas furnace backup) for inland homes that still get cold winters.
What Our Customers Say
We got a Lennox furnace and AC combo for our 2,400 sq ft home. The online estimator gave us an accurate quote and there were zero surprises on install day. They pulled permits, handled everything with the city, and even helped us understand the HEEHRA rebate process.

Furnace & AC InstallationReplaced our furnace and added central AC for the first time. Went with a Rheem system based on their recommendation. The price from the online estimator matched exactly. They ran new electrical, installed the lineset, and the evaporator coil — all in two days.
