Modesto, California: HVAC Replacement Cost Calculator

Replacing an HVAC system in Modesto typically runs $4,000 to $7,500 for a central air conditioner alone, $7,500 to $13,000 for a matched AC and gas furnace, and $6,000 to $12,000 for a heat pump. Ductless mini-split projects span $3,500 to $10,000 depending on how many zones you need. Add $250 to $550 for the permit, since Modesto installations have to be permitted and meet California's Title 24 energy standards.

Worked example

Take a 1,750-square-foot single-story home in north Modesto with an original AC condenser and 20-year-old gas furnace in the hallway closet. Because the ductwork is reusable and both pieces are being swapped at once, the job lands in the middle of the $7,500 to $13,000 AC-plus-furnace range — roughly $10,000 to $11,000 installed. Budget another $250 to $550 for the permit and Title 24 documentation, and expect the total to move toward the top of the range if the contractor has to seal or replace attic duct runs.

Frequently asked questions

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

Yes. HVAC changeouts are permitted work in California, and permit fees in the Modesto area generally run $250 to $550. The permit also triggers Title 24 compliance checks, which can include duct leakage and refrigerant charge verification.

Is a heat pump worth it instead of a new AC and gas furnace?

A heat pump in Modesto runs $6,000 to $12,000 installed, compared with $7,500 to $13,000 for a new AC and gas furnace pair. Because a heat pump handles both heating and cooling with one outdoor unit, it can come in below a full dual-fuel replacement, and TECH Clean California heat pump incentives may reduce the cost further depending on your utility.

What rebates are available for Modesto homeowners?

TECH Clean California offers heat pump incentives, but the amount varies by utility, so check techcleanca.com and confirm with your provider before signing a contract. Ask your installer whether they are a TECH-participating contractor, since some incentives are processed through the contractor rather than paid to you directly.

Why do HVAC quotes in Modesto cost more than the national average?

Labor in the Modesto market runs about 16% above the national average, with HVAC technicians earning around $36.24 per hour. Title 24 testing and documentation requirements also add time to each job, which shows up in the installed price.

How do I check that a Modesto contractor is licensed?

California HVAC contractors need a C-20 license from the Contractors State License Board, and you can verify any license number for free on the CSLB website. Make sure the company pulling your permit is the same licensed contractor doing the installation.
