Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterHow Much Does Air Duct Cleaning Cost in Las Vegas?
Air duct cleaning in Las Vegas typically runs $350 to $750 for a standard single-family home, with most two-story houses in the valley landing between $450 and $900. Larger homes over 3,000 square feet, or systems that haven’t been touched in a decade, often fall in the $900 to $1,200 range. Add dryer vent cleaning and you’re usually looking at another $125 to $200 on the same visit.
Those numbers cover a full source-removal cleaning: every supply and return run, the main trunk lines, the blower compartment, the evaporator coil area, and the registers. If someone quotes you $99, that price is for one thing and one thing only, and it won’t be the whole system. We’ll get into why that gap exists further down, because it matters more in Las Vegas than it does almost anywhere else.
Hollis Air Duct Cleaning has been working in homes since 2004 as part of the Garrison Partners family, and every job gets a written price before a technician touches a single register. No moving numbers at the door, no surprises once the truck is parked.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what the line items actually look like in the Las Vegas market this year. These are the ranges we see and quote, not national averages pulled from a website that’s never set foot in Clark County.
| Service | Typical Price Range | What It Covers |
|---|---|---|
| Standard single-story home (up to 1,800 sq ft) | $350 – $550 | All supply and return vents, main trunk lines, blower, registers |
| Two-story or mid-size home (1,800 – 3,000 sq ft) | $450 – $900 | Full system plus additional runs and second-zone trunk lines |
| Large home (3,000+ sq ft) | $900 – $1,200 | Multi-zone systems, extended runs, multiple air handlers |
| Dryer vent cleaning (add-on) | $125 – $200 | Full lint removal from dryer to exterior termination point |
| Duct sealing (per system) | $400 – $800 | Mastic sealing at joints, boots, and plenum connections |
| Evaporator coil cleaning | $150 – $350 | Coil face and fins cleaned while system is open |
| Negative-air setup and HEPA containment | Included | Keeps dislodged debris from settling back into living space |
The spread between $350 and $1,200 comes down to system size, how many years of dust and debris have built up, and whether the ducts are accessible or buried behind finished walls. A 1,400-square-foot ranch in Summerlin with one air handler is a straightforward job. A 3,600-square-foot house in Henderson with two systems, a finished basement-style layout, and original 2003 ductwork is a different afternoon entirely.
What moves the number up: additional air handlers, hard-to-reach runs, heavy construction debris from a recent remodel, mold or microbial growth requiring treatment, and duct sealing if we find leaks at the joints. What moves it down: a home that’s been cleaned within the last three years, easy attic access, and a single-story layout with a compact duct system.
One thing worth stating plainly. If a quote doesn’t specify whether the trunk lines are included, assume they aren’t, and ask. Trunk lines are the big rectangular duct runs that feed every branch in the house. Cleaning the branches but skipping the trunk is like vacuuming a room and leaving the closet untouched.
What Affects Air Duct Cleaning Pricing in Las Vegas
Las Vegas is not a humid market, and that changes the math. We don’t fight the mold problems that coastal cities deal with, but we fight dust, and we fight it hard. Here’s what actually drives the price here.
- Square footage and number of air handlers. Most Las Vegas homes over 2,500 square feet run two separate HVAC systems, one for upstairs and one for downstairs. Two systems means two full cleanings, two blower compartments, and roughly double the labor. That’s the single biggest cost factor in the valley.
- Duct material and age. Original flex duct from a 1990s build behaves differently than sheet metal from a 1970s ranch near Downtown. Flex duct with loose inner liners and crushed sections needs more careful handling, and sometimes the honest recommendation is replacement rather than cleaning. We tell you that before we start, not after.
- Construction dust and remodeling. Drywall dust is relentless. If you’ve had a kitchen remodel, a room addition, or new flooring installed in the last two years, that fine gypsum powder has been pulled straight into your return air and coated every duct surface. Post-remodel cleanings in neighborhoods like Green Valley and Aliante routinely run at the higher end of the range.
- Desert dust infiltration. Spring and early summer wind events push fine caliche and silica dust through every gap in the envelope. Homes near the edges of the valley, out toward Red Rock or up against the mountains in the northwest, pull in more of it than homes in the middle of the city.
- Pets and occupants. Dander loading is real. Two dogs and a cat in a 2,000-square-foot house produce a heavier debris load than a home with no pets, and that means more time on each run and a heavier filter change afterward.
- Accessibility. Attic access in a single-story Las Vegas home is usually simple. Crawlspace or soffit-only access, or ducts buried under blown-in insulation, adds hours. We quote based on what we can see and what you tell us, and we confirm on arrival before any work begins.
Notice what’s not on that list: the brand of vacuum truck in the driveway. Every legitimate air duct cleaning company in Las Vegas uses negative-air containment and a rotary brush system. What differs is whether they run the brush through every branch or just wave it at the main trunk for twenty minutes. That difference is invisible on the invoice and very visible in the air you breathe six months later.
Hollis uses Rotobrush rotary brush systems for the agitation work and Nikro negative-air machines to hold containment while we clean. We also carry filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman, and we’ll explain in plain terms what each one does for the air moving through your house. A rotary brush system is a spinning brush head on a flexible whip that scrubs the inside walls of each duct run. A negative-air machine is a large vacuum that creates suction at the far end of the system so dislodged debris travels out, not into your living room.
Why Las Vegas Duct Cleaning Differs From Other Markets
Most pricing guides you’ll read were written for a generic American suburb with four seasons and moderate humidity, unlike our detailed Long Beach, CA price guide. Las Vegas doesn’t work that way, and the difference shows up in what we find inside ducts here.
Our air conditioning runs seven to eight months a year. That’s roughly twice the runtime of a system in the Midwest or Northeast. Every hour the blower runs, it’s pulling air through the return and pushing it through the supply. More runtime means faster debris accumulation on the evaporator coil, the blower wheel, and the duct walls. A Las Vegas home that’s never had its ducts cleaned by year eight typically has a heavier coating than a comparable Chicago home at year twelve, or even a home in Los Angeles where systems run less.
We also don’t get the seasonal flush that comes with a wet spring. Snowmelt and rain push humidity through homes in other markets-like those covered in our Manhattan, NY price guide-and, ironically, keep some of the fine particulate from settling as hard. Here, it’s dry, it’s static, and the dust binds to surfaces and stays. That matters because once it’s bonded to the inside of a flex run, no amount of homeowner-grade vacuuming will remove it.
And then there’s the monsoon window. From roughly July through September, humidity spikes for short bursts. If your ducts have a heavy organic load from years of dust and pet dander, that brief moisture can activate odors you’d never noticed in the dry months. Homeowners in Las Vegas call us in August more than any other month, and nine times out of ten the complaint is “the house smells musty when the AC kicks on.” That’s a duct cleaning problem, not an AC problem.
How to Save on Air Duct Cleaning
You don’t need to chase the lowest quote to save money. You need to avoid paying twice. Here’s what actually works.
- Bundle the dryer vent. Adding dryer vent cleaning to the same visit runs $125 to $200 instead of a separate service call. The technician is already set up with the right equipment, so the labor overlaps.
- Skip the annual plan. For a typical Las Vegas home with pets, every three to five years is the honest interval. A home with no pets and a good filtration setup can stretch to five or six. Annual cleaning is a subscription product, not a maintenance necessity.
- Address filtration at the same time. A proper MERV-rated filter in the return grille and a tight filter rack reduce how fast the ducts load back up. It’s a small line item that delays the next cleaning by a year or two.
- Fix duct leaks before they get worse. A leaking duct joint in the attic pulls in unconditioned attic air, which in a Las Vegas summer can be 140 degrees. That intake carries dust and drives up your power bill. Sealing with mastic runs $400 to $800 per system and typically pays back within a couple of cooling seasons.
- Get the price in writing before work starts. This is the biggest one. The $99 teaser price is real, and so is the $1,400 invoice at the door once the technician “discovers” mold in the plenum. A written price before any work begins removes that entire category of problem.
Every Hollis estimate is free and it’s written before we touch a register.

FAQs – Air Duct Cleaning Cost in Las Vegas
How much does air duct cleaning cost in Las Vegas?
Between $350 and $750 for a standard single-family home, and $450 to $900 for most two-story houses in the valley. Homes over 3,000 square feet with multiple systems run $900 to $1,200. Call (361) 326-5060 for a free quote based on your specific square footage and system count.
Is it cheaper to clean ducts or replace them?
Cleaning almost always wins on cost. A full duct replacement in a 2,000-square-foot Las Vegas home runs $3,000 to $8,000, while cleaning is $350 to $750. Replacement only makes sense when flex duct is crushed beyond recovery, contaminated with microbial growth that won’t come off, or badly undersized for the system. We’ll tell you honestly which situation you’re in before any work starts.
Can you come today?
Often yes, depending on the schedule and your location in the valley. Phones are answered live 24 hours a day, so you’ll reach a person, not a voicemail loop. For same-day or next-day scheduling, call (361) 326-5060 and we’ll tell you exactly what’s open.
How often should I have my ducts cleaned in Las Vegas?
Every three to five years for most homes, and every two to three if you have multiple pets, a recent remodel, or someone in the house with allergies or asthma. Las Vegas systems run seven to eight months a year, so they accumulate debris faster than systems in cooler climates.
Does duct cleaning actually lower my power bill?
It can. A dust-coated evaporator coil and a restricted blower wheel force the system to work harder to move the same volume of air. Cleaning restores airflow, and duct sealing closes the leaks that pull 140-degree attic air into your system. Combined, homeowners typically see a modest reduction in summer cooling costs, though the exact number depends on the age and condition of your HVAC equipment.
What’s the cheapest air duct cleaning in Las Vegas?
The $99 advertised specials exist, but they usually cover one system with a limited number of vents and no trunk line cleaning. Expect an upsell at the door once the technician arrives. A written price before work begins is what protects you, and that’s how every Hollis job is priced. Call (361) 326-5060 for a free estimate with the full scope spelled out.
What to Ask Before You Hire Anyone in Las Vegas
Six questions separate a legitimate duct cleaning company from a truck that shows up with a shop vac and a business card.
- Is the price written down before work starts, and does it list every duct run, trunk, and component?
- Do you use a rotary brush system and negative-air containment on every job, or only on some?
- Are your technicians background-checked and uniformed?
- What happens if the work fails within a year?
- Will you show me photos of the inside of my ducts before and after?
- Are you running the brush through every branch, or just the main trunk?
If a company won’t answer all six on the phone, before you’ve paid anything, that tells you what the rest of the relationship will look like. Hollis has been operating since 2004 as part of the Garrison Partners family, and every one of those questions has a one-sentence answer. Background-checked techs, rotary brush and negative air on every job, written price before work starts, and a 365-Day Done Right Promise that puts the follow-up in writing.
If you’ve been burned before by a no-show, a price that jumped at the door, or a crew that left dust on the baseboards and vanished, that’s the exact reason we run on The Garrison Code. Arrive inside the window. Price in writing. Complete the job by the book. Leave the site clean. It’s not a slogan, it’s the operating checklist.
