Air duct cleaning cost in Las Vegas

Prices last checked October 29, 2026

Air duct cleaning in Las Vegas typically costs $217 to $479, about $327 on average in local listings, and $450 to $1,000 for a thorough job on an average home. If you see a "$49 whole house" deal, that's the classic bait-and-switch. The EPA says ducts don't need routine cleaning, only when there's visible mold, pests or heavy debris.

The low and typical marks are local listings. The high end is the EPA's and a Las Vegas company's top figure for a full job.

The $49 bait-and-switch

It's a well-known trap. An ad offers your whole house for $49 or $99. Once the crew is inside, they "find" mold or a problem, and the bill jumps to hundreds or thousands.

• A Las Vegas HVAC company calls $49 to $99 whole-house deals unrealistic and puts a legit job at $450 to $1,000 for an average home.
• KTNV reported Las Vegas ads like "$5 a vent, we'll clean your whole house for $75," followed by sudden claims of mold in the vents.
• The Better Business Bureau has warned about $49.95 to $89.95 specials followed by bogus mold tests and pressure to pay much more.
• NADCA, the duct cleaning trade group, warns about "blow-and-go" companies that charge a nominal fee and do a poor job.

Protect yourself: get a written price before anyone starts, get at least three estimates (the EPA's advice), and be wary of anyone who says they're "EPA certified." The EPA says to watch for that claim. If someone says you have mold, ask to see it and get a second opinion.

Do you actually need it?

Probably not on a schedule. The EPA says it doesn't recommend routine duct cleaning, only as needed, and that duct cleaning has never been shown to prevent health problems. It suggests cleaning when:

• there's substantial visible mold inside hard (sheet metal) ducts,
• ducts are infested with insects or rodents, or
• ducts are clogged with excessive dust and debris.

ENERGY STAR says to inspect, clean or change your filter monthly. If you do hire someone, the EPA says they should follow NADCA's standards.

Cleaning prices

low to high, typical. Bars use the same scale, up to $1,400.

Local listings don't define what's included, and HomeBlue prices by vent ($33 to $44 each in Las Vegas, often with a 10-vent minimum). Ask how many vents and returns are included and whether the main trunk lines and the air handler get cleaned.

Dryer vents, sealing and replacement

low to high, typical. Bars use the same scale, up to $7,000.

Duct sealing and full replacement have no Las Vegas price we could find, so those rows are national.

NV Energy duct sealing rebate

NV Energy's 2026 home improvement rebate sheet lists, one per home:

• $100 for Tier 1 duct sealing, with before and after photos.
• $200 for Tier 2, with before and after leakage test results.
• $200 or $300 for sealing plus duct insulation (at least 10 feet of exposed duct, upgraded from R-2 or less to at least R-8).

The home needs central AC serving most of the house and existing ducts. Submit within 180 days of the work. This is for sealing, not cleaning.
