Like-for-like by size
The refrigerant line
New equipment uses A2L refrigerants such as R-454B; some pre-2025 R-410A stock can still be installed (A2L guide). We found no published LA figure for an A2L premium, so none is shown: no published figure.

Coast or Valley: why the size, and so the price, moves
Size drives replacement prices more than any other line, and in Los Angeles the right size depends on where the house sits. On NOAA's 1991–2020 normals, LAX averages 4.8 days a year at 90 °F or above, downtown (USC) 25.6, Burbank airport 53.9 and Woodland Hills 115.3, with 35.6 days at 100 °F or more. Two houses of the same floor area can land a size apart, which on the published ranges is a step of several thousand dollars.
Ask how the size was chosen
A quote should rest on a Manual J load calculation, not a square-foot rule. Our sizing preparation sheet lists what to have ready, and what size AC an LA home needs explains the inputs.

How these ranges are built, and what they are not
- Only published Los Angeles figures. Each range is what a named LA HVAC company or cost publisher printed, with the date on the page and the date we read it.
- No interpolation. If no source prints a size or a line, the table says "no published figure" or leaves the size out; we do not fill gaps from national averages.
- Widest honest band. Where two sources print the same size, the range runs from the lowest low to the highest high.
- Not our quote index. This site's own figures need at least 12 dated LA quotes per cell before they publish; that dataset is still being collected.
Use the ranges to check quotes, not to replace them
Itemized written quotes from licensed C-20 contractors are the only real price. Put them side by side with the quote comparison tool and confirm the license with the CSLB check.

Questions
How much does it cost to replace an AC in Los Angeles?
$5,500–$12,000 for central AC on one LA publisher's 2026 range; a full system $9,000–$22,000.
Is a heat pump swap more expensive?
A 3-ton ducted heat pump prints at $12,000–$15,000 against $8,000–$16,000 for a 3-ton AC, before any LADWP rebate.
Do I need a permit to replace my AC?
Yes, with Title 24 duct testing and third-party verification.
Is sales tax included in these prices?
California treats an installed air-conditioning unit or furnace as a fixture, so sales tax applies to its price; ducts are materials, taxed on the contractor's cost; installation labor is not taxed. Ask whether a quote includes it.
How much deposit should I pay?
CSLB cautions that a down payment should not exceed 10 percent of the contract price, and later payments should not run ahead of the work done or materials delivered.
