Santa Rosa, California: HVAC Replacement Cost Calculator

Replacing an HVAC system in Santa Rosa typically runs $6,000 to $12,000 installed for a heat pump, or $7,500 to $13,000 for a matched central AC and gas furnace pair. Standalone equipment costs less: central AC alone falls between $4,000 and $7,500, and a gas furnace between $3,500 and $7,000. Sonoma County labor runs about 16% above the national average, with local HVAC technicians earning around $36.24 an hour, so labor is a meaningful share of every quote you'll get.

Worked example

Take a 1,750-square-foot single-story home in the Rincon Valley area with a 20-year-old gas furnace and an aging condenser. The owners decide to replace both at once with a matched AC and furnace system using the existing ductwork, which is in decent shape and needs only minor sealing. With Santa Rosa's labor rates and Title 24 compliance work factored in, that job lands near the middle of the $7,500 to $13,000 range — roughly $9,500 to $10,500, plus a city permit in the $250 to $550 window. Had they switched to a heat pump instead, the equipment side would fall in the $6,000 to $12,000 range and they could look into TECH Clean California incentives through their utility.

Frequently asked questions

How much does it cost to replace a full HVAC system in Santa Rosa?

A complete central AC and gas furnace replacement in Santa Rosa runs $7,500 to $13,000 installed, while an all-electric heat pump system runs $6,000 to $12,000. Where you land depends on system size, efficiency tier, and how much ductwork or electrical upgrade the job requires.

Do I need a permit to replace an HVAC system in Santa Rosa?

Yes. Expect permit fees of roughly $250 to $550 for a residential HVAC changeout in the Santa Rosa area, and your installation has to meet California's Title 24 energy standards. A reputable contractor pulls the permit for you and includes the fee in the written quote.

Are there rebates for heat pumps in Santa Rosa?

TECH Clean California offers heat pump incentives, but the amount varies by which utility serves your address. Check techcleanca.com before you sign a contract, since some incentives are processed by the installing contractor rather than reimbursed to you afterward.

Is a heat pump a good fit for Santa Rosa's climate?

Santa Rosa sits in California climate zone 3, with mild winters and warm but not extreme summers, which is well suited to heat pump operation year-round. A heat pump handles both heating and cooling from one system at $6,000 to $12,000 installed, versus $7,500 to $13,000 for a separate AC and gas furnace.

How do I verify an HVAC contractor is licensed in Santa Rosa?

California requires HVAC contractors to hold a C-20 license from the Contractors State License Board, and you can look up any license number for free on the CSLB website. Confirm the license is active and matches the business name on your quote before work begins.
