How Much Does a New AC Cost in Las Vegas?

A full central air replacement in Las Vegas runs about $5,000 to $14,000 installed in 2026, with most straightforward 3 to 5 ton split-system jobs landing between $7,000 and $11,000. Here is what moves the number.

What drives the price

• Size. Measured in tons; a typical valley home needs 3 to 5. Bigger is not better; an oversized unit short-cycles and dehumidifies poorly.
• Efficiency. Baseline equipment at the current federal minimum is cheapest. Two-stage and variable-speed systems cost $2,000 to $5,000 more and cut summer bills most.
• Type. Replacing a rooftop package unit, common on older central and east Las Vegas homes, adds crane and labor cost. Heat pumps cost a little more than AC-plus-furnace and heat efficiently in Las Vegas winters.
• Extras. New line set, electrical upgrades, duct repairs, a new thermostat, and the permit.

Rebates and credits

NV Energy has offered rebates on qualifying high-efficiency equipment; programs change yearly, so ask the installer to check current ones. Federal tax credits for efficient equipment have changed too; confirm what applies in the year you buy.

What a quote must include

• Equipment model numbers and the efficiency rating
• Permit and inspection (City of Las Vegas, Henderson, North Las Vegas, or Clark County)
• Disposal of the old equipment
• Warranty terms, and who registers it
• A start-up and test with readings
