How to check an AC contractor in Nevada

Last checked October 29, 2026

Before you hire anyone for AC work in Nevada, look up their license on the Nevada State Contractors Board site and make sure it's an active C-21 (Refrigeration and Air-Conditioning). Hiring a licensed contractor also protects you: if a job goes bad, you can file a complaint and may qualify for the state's Residential Recovery Fund, up to $40,000.

Check the license (2 minutes)

Open the Contractors Board license search and search the company name or license number from the quote.
Make sure it's active.
Check the classification. AC work is C-21. A C-21b covers installing AC. A C-21d (maintenance) license alone can do repairs but not replace a whole condenser or air handler.
Look at any disciplinary history.

Red flags in a quote or a sales visit

"You need a whole new system" on the first visit, with no second look. In a 2026 r/vegaslocals thread, a Summerlin homeowner got a $13,000 replacement quote; a second company quoted $8,000 and said it didn't need replacing at all.
A price that drops a lot when you push back. It tells you where the first number came from.
No model numbers. You can't compare "a 4 ton system" to anything.
Sizing by your old unit or square footage, with no load calculation.
Pressure to sign today or a "today only" price.
Vague on permits. Henderson's permit records show AC change-outs permitted as appliance replacements, and Clark County requires a permit to replace mechanical systems. Ask who pulls it.
Repeated refrigerant top-offs instead of finding the leak.

Don't lose the warranty

Many manufacturers only give the long warranty if the equipment is registered. Carrier, for example, requires registration within 90 days, or you get the standard 5-year parts-only warranty, and labor is only covered under a specific dealer program. Ask the contractor to register it and send you the confirmation.

If something goes wrong

File a complaint with the Contractors Board: up to 4 years after the work for a licensed contractor, 2 years for unlicensed. If it's not an emergency, file before you hire someone else to fix it, so the Board can inspect.
Residential Recovery Fund: if you live in the single-family home and used a licensed contractor, you may be able to recover up to $40,000 per claim. File within 4 years of the work.
Board phone: (702) 486-1100 in Southern Nevada.
