HVAC Replacement Cost in Los Angeles, CA: 2026 Price Guide

HVAC replacement pricing by system type

For homes with existing ductwork, a full furnace-plus-AC replacement runs $9,000 to $16,600 in the Los Angeles metro, with higher-efficiency SEER2 systems and premium brands pushing toward the top of that range. Central AC alone, added to an existing furnace, runs $6,500 to $12,500 installed.

For homes without ducts, common throughout Eagle Rock, Highland Park, and Echo Park, a ductless mini-split system typically runs $3,500 to $6,500 per zone, with whole-home multi-zone setups often landing between $12,000 and $20,000 depending on how many rooms need coverage.

Adding new ductwork to a previously ductless home instead of going ductless can cost $2,500 to $7,500 on top of equipment costs, so many homeowners in older neighborhoods find mini-splits more cost-effective overall.

Permit and Title 24 requirements for replacement

Any HVAC system replacement in the City of Los Angeles requires a mechanical permit from LADBS, and many standard changeouts qualify for the Express Permit online process rather than a full plan check. Your contractor should confirm eligibility for the online process before starting work.

California's Title 24 energy code requires HERS field verification testing on most furnace and AC replacements, checking airflow, refrigerant charge, and duct leakage after install. This is a mandatory, code-required cost, not an optional upsell, and should appear as a line item in your quote.

Confirm your contractor is scheduling both the LADBS final inspection and the HERS rater visit, since a system that passes neither can create problems if you sell the home later.

Choosing the right system for your home and neighborhood

Valley homes in Sherman Oaks and Woodland Hills benefit from correctly sized systems built for sustained summer heat; ask for a Manual J load calculation rather than a rule-of-thumb sizing based on square footage alone.

Coastal and hillside homes in Mar Vista, Westchester, and Silver Lake often run cooling far less, so a smaller, efficient system or even a targeted mini-split for bedrooms may be more cost-effective than a full central system.

San Pedro's coastal exposure calls for corrosion-resistant outdoor equipment coatings, and hillside access constraints in Silver Lake may require contractors experienced with tighter equipment placement and crane logistics.

Comparing bids and finalizing your project

Every bid should separately itemize equipment brand and SEER2 rating, labor, LADBS permit fees, and Title 24 HERS testing costs, so you can compare true scope rather than a single bottom-line number.

Confirm the installing company's C-20 license through the CSLB Check A License tool, and ask whether they'll handle the LADBS permit filing and HERS rater scheduling directly or expect you to coordinate those steps yourself.

Ask about applicable rebates, such as LADWP's Consumer Rebate Program for qualifying heat pump systems, before finalizing equipment choice, since rebate eligibility can affect which system makes the most financial sense.

Typical cost ranges

Ranges are general estimates gathered from homeowner-reported quotes, not an offer or a quote for your project.
