AC Installation Los Angeles: $7,400 to $15,000 (2026 Prices)

ConsumerAffairs' row and the LADWP rebates are Los Angeles figures; installed prices by size are national. Ductwork, panel upgrades and permits change the quote.

Heat pump installation in Los Angeles: why the rebates point that way

LADWP pays $300 per ton for a qualifying heat pump and $100 to $120 per ton for a non-heat-pump system, its October 2025 rebate sheet shows, so choosing a heat pump over a plain AC raises the rebate on every ton. LADWP's fact sheet says to apply within 12 months of purchase. Owners rebuilding after the January 2025 fires qualify for HOME LA Express at $1,000 to $1,250 per ton ducted and $1,500 to $2,500 per ton ductless.

Los Angeles also needs heat as well as cooling. NOAA's normals for the downtown USC station show 1,295.7 cooling degree days and 1,005.1 heating degree days a year, so a heat pump that both heats and cools fits the climate. If you keep a gas furnace, SoCalGas pays $1.40 to $25 per kBTUh on an ENERGY STAR furnace at 92% AFUE or higher, with proof of permit closure.

What is closed in 2026: state and federal money

The big state and federal programs are not available for a single-family install this year. TECH Clean California says its heat pump HVAC incentives were fully reserved as of November 14, 2025; the California Energy Commission says HEEHRA single-family rebates were fully reserved statewide as of February 24, 2026, with a waitlist; and the IRS says the 25C credit does not apply to equipment placed in service after December 31, 2025. National prices and the full rebate picture are on heat pump installation cost.

LADBS permit and HERS test for a new AC in LA

A same-size swap goes under an LADBS Express Permit: the bulletin lists replacing AC units with the same size and type, adding AC equipment rated 5 tons or less, and ductwork alteration among its no-plan-check items. The California Energy Commission says properly permitted HVAC work triggers any necessary HERS testing, HERS paperwork is needed to close the permit, and those field verification rules moved into Title 24, Part 6 on January 1, 2026.

An unpermitted install skips the HERS test, and SoCalGas asks for proof of permit closure on its furnace rebate. Owners can pull a mechanical permit only as owner-builders: LADBS requires that you do the work, have lived in the home 12 months, and hold owner-builder permits on no more than two structures in three years.

Sizing and the quote: what drives the price

Size is the first driver. HomeGuide's national installed prices run $4,700 to $6,500 for a 1.5-ton unit and $7,000 to $9,500 or more for 5 tons; Fixr's run $3,650 to $6,250 and $7,800 to $14,000 for the same sizes. Ask for a load calculation rather than a match to the old unit. Ductwork changes, a new electrical circuit and the permit add to the price; if the panel needs work, see electrical repair in Los Angeles.

What to ask an LA AC installer

1. Will you do a load calculation, and what size do you recommend?
2. Is the LADBS permit and the HERS test in the price?
3. Will you file the LADWP rebate, and does the model qualify?
4. What is your CSLB license number (C-20), and can I see proof of insurance?
5. What warranty covers parts and labor?
