AfterSupply Duct Cleaning in Las Vegas, NV
Supply duct cleaning in Las Vegas typically runs $300 to $650 for a full home, depending on the number of vents and how much build-up has settled in the lines. Supply ducts are the passageways that carry conditioned air from your HVAC unit into every room, and in a city where the AC runs hard for six months a year, they collect dust, pet hair, and fine desert silt faster than most homeowners realize. Kestrel Air Duct Las Vegas performs this work with negative-air extraction and brush agitation, and every job carries a written price before a single vent is opened. If you have questions about what’s involved or want to talk through your system, call (725) 210-0612 any time; a live person answers, 24/7.
This page covers the supply side specifically. For a broader look at the full system including return ducts and the air handler, see our main Air Duct Cleaning in Las Vegas page. If you’re just starting your research, our home page lays out how we work and what the Kingswell Guarantee covers.
When You Need Supply Duct Cleaning
Most homes we visit in Summerlin, Henderson, and the older central neighborhoods share the same story: the return side gets the attention, and the supply side gets forgotten. But the supply side is where the air you actually breathe enters your living space. Here are the signals that tell us your supply ducts need work:
- Dust returns within two days of wiping surfaces. In Las Vegas, fine gypsum dust from surrounding desert and construction settles into supply ducts and gets redistributed every time the blower kicks on. If your coffee table starts showing a film again by midweek, the supply lines are likely the source.
- You notice weak airflow from specific rooms. Supply ducts clogged with debris reduce velocity. A bedroom that’s always five degrees warmer than the rest of the house often has a restricted supply run, not an undersized AC unit.
- Allergy symptoms ease when you leave home and flare when you return. Supply ducts distribute contaminants evenly through the living space. If multiple occupants react the same way in different rooms, the distribution path deserves a hard look.
- You find visible debris at the supply registers. Lift an existing vent cover near the living room and look past the grille with a flashlight. Gray or brown fuzz caked on the duct walls is a sign it’s time. We see this constantly in homes built before 1995 in the older Las Vegas subdivisions.
- You renovated, sanded drywall, or installed new flooring in the last year. Construction dust travels everywhere, and a surprising amount of it ends up inside supply runs. A fresh build or a kitchen remodel can coat the supply ducts with fine white powder in under a week.
- Your last duct cleaning was more than three years ago, or you have no record of one. For a 2,000-square-foot house with pets and the AC running from April through October, we recommend an inspection at minimum every two to three years. Supply ducts hide problems quietly until they don’t.
Our Supply Duct Cleaning Process
The process we use at Kestrel Air Duct Las Vegas is deliberate, and nothing is left to guesswork-our Video Inspection confirms every step. Supply duct cleaning is not a quick pass with a shop vac; it is a sequenced removal of debris from the full run of the supply lines, followed by verification that air is moving the way it should. Here is exactly what happens on a typical job:
- Walk-through and written price. Our technician starts by counting supply vents, measuring the linear feet of duct, and checking for pre-existing damage. You get a written quote covering the complete job before any tool leaves the truck. That price does not change at the door, and it will not change after we start.
- Register removal and line inspection. Every supply vent cover comes off, and we run a camera or visual inspection into the run. In Las Vegas homes, this often reveals surprises: a builder’s soda can, a child’s toy, or a dead scorpion. We show you what we find and proceed from there.
- Rotary brush agitation. We feed a Rotobrush rotary brush system down each supply run. The spinning bristles knock dust, hair, and caked debris free from the duct walls; without this mechanical step, a vacuum alone lefts a stubborn film behind.
- Negative-air extraction with HEPA filtration. A Nikro negative-pressure unit seals to the system and pulls loosened debris out under vacuum. The machine uses Abatement Technologies HEPA filtration to capture the particles at the collection point, so they never recirculate into your bedrooms, kitchen, or hallway while we work. Negative-air extraction simply means the air pressure inside the ducts is kept lower than the surrounding room, which pushes every loose particle toward our machine rather than out into the house.
- Supply-side register wipe-down and final airflow check. We wipe each supply vent clean, reinstall it flush, and do a room-by-room check with an airflow meter to confirm the system is delivering the way it should after cleaning. If a room was weak before, we verify the improvement before we pack up.
- Written guarantee and follow-up expectations. Every job ends with the 365-Day Done Right Promise in writing. If anything we cleaned clogs prematurely or the work doesn’t hold, we return and make it right at no charge. You will know how to reach us and exactly what the guarantee covers before we leave the driveway.
Supply Duct Cleaning Pricing in Las Vegas
Here is what Las Vegas homeowners should expect to pay for supply duct cleaning. These are honest ranges from jobs we have performed across the valley, not teaser numbers designed to get a foot in the door:
- Small home (up to 1,200 sq ft, 6-8 supply vents): $300 – $400
- Average single-family home (1,200 – 2,500 sq ft, 8-14 supply vents): $400 – $550
- Large or multi-story home (2,500+ sq ft, 14+ supply vents): $550 – $650
What moves the price is mostly the number of supply vents and the total linear footage of duct, not the square footage of the house. A two-story Summerlin home with 17 supply vents and long runs will land at the higher end even if the floor plan is smaller than a single-story Henderson house with 10 vents. Accessibility matters too: attic-installed supply ducts in some Las Vegas homes sit low and tight, which adds time and care to the brushing and extraction. And homes with flex duct that has sagged, collapsed, or been chewed through by desert rodents will need repair work quoted separately and in writing before we begin our Air Duct Cleaning services.
We never charge by the register as a surprise, and we never add a fuel surcharge or a trip fee at the end. The written price you receive upfront is the price you pay. To get an exact number for your specific supply duct configuration, call (725) 210-0612 and ask for a free estimate. Every call is answered by a live person, any time of day, and the estimate is provided after a brief conversation about your home, not after a pressure pitch.
FAQs – Supply Duct Cleaning
How often should supply ducts be cleaned in Las Vegas?
Every two to three years, depending on pets, occupancy, and whether you run your HVAC system year-round. In Las Vegas, where the cooling season stretches from April through October and summer dust is constant, we find that most homes benefit from a supply-side cleaning every 24 to 36 months. Homes with large dogs, multiple cats, recent renovations, or occupants with allergies often need it more frequently. If you’re unsure, call (725) 210-0612 for a phone consultation; we can tell you what to look for in about ten minutes.
Will supply duct cleaning reduce dust in my home?
In most Las Vegas homes we service, yes, substantially. Supply ducts are the final leg of the air delivery path, so any dust, silt, or pet dander sitting in those lines gets pushed directly into your living space on every cycle. After we perform rotary brush agitation and negative-air extraction, homeowners consistently report slower dust accumulation on furniture and fewer visible particles floating in sunlight near the vents. If someone in your home has respiratory sensitivities, the difference is usually noticeable within the first week. For homes that want additional filtration between cleanings, we can recommend Honeywell or Aprilaire filters that trap ongoing airborne material before it reaches the supply side; see How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Las Vegas, NV for full service details.
Is supply duct cleaning covered by the 365-Day Done Right Promise?
Yes, entirely. The 365-Day Done Right Promise covers the full supply duct cleaning we perform. If within 365 days of the job, you believe the work fell short of our standard, the process is simple: call us at (725) 210-0612 and tell us what you’re seeing. A technician returns, inspects the supply ducts, and if our work did not hold, we re-clean the affected runs at no charge. You do not need to produce a receipt, argue a case, or schedule around a limited claims window. The guarantee is in writing on every job we perform, which is a practical standard few companies in this market are willing to put on paper.
How does supply duct cleaning differ from return duct cleaning?
Supply ducts carry conditioned air from the blower into each room under positive pressure, while return ducts carry stale room air back to the air handler under negative pressure. The result is that supply ducts tend to hold finer, drier material; desert silt and fine dust that becomes airborne each cycle. Return ducts, by contrast, trap heavier lint, hair, and visible fibers. A proper cleaning treats both sides, because they face different conditions. For an overview of the complete system, including what a full Air Duct Cleaning in Las Vegas job covers, visit our main service page.
Do you sell air filters or indoor air quality products after cleaning?
We do, but only if you ask. We keep Honeywell and Aprilaire filtration products available for homeowners who want to sustain cleaner supply air between professional cleanings, and we can talk through which filter makes sense for your system. We also have experience with Guardsman IAQ products for clients who want a higher level of ongoing filtration. We never bundle these into the cleaning price or pressure you into a purchase. If you want a simple answer on whether an upgraded filter is worthwhile for your specific unit, ask us during your estimate or call (725) 210-0612 and ask directly; you will get a straight answer and a written price for whatever you choose.
The Kestrel Standard for Supply Duct Work
There is a reason we operate under the Kingswell Guarantee and name it openly on every job. Supply duct cleaning is an invisible service. You cannot easily see what the technician did after the vent covers are back in place, and a dishonest company can charge you for thirty minutes of waving a camera around a dark duct. We make the work verifiable. The written price is in your hands before any cleaning starts. The arrival window is set when you book, and our technician is on time. The job site is left cleaner than we found it, with each vent wiped and the floor around every register swept. And the 365-Day Done Right Promise is not a phrase in a sales script; it is a written guarantee on your invoice, signed by us, with a free return visit if the work falls short within the year.
The code we work by is called the Kingswell Way. It has five parts: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, and come back if it fails. Our technicians are background-checked, uniformed, and trained on Rotobrush, Nikro, and Abatement Technologies equipment. They are not subcontractors, and they do not work for tips. When you hire Kestrel Air Duct Las Vegas, the person who shows up is accountable to the company that wrote your guarantee.
Dale Whitmore leads Kestrel Air Duct Las Vegas. He has built the Las Vegas operation around one expectation: every supply duct job should be measured not by what the technician said happened, but by what the homeowner can verify and put back in writing if something goes sideways. That is the standard we hold, and it is the reason homeowners in Summerlin, Henderson, and the older neighborhoods in central Las Vegas keep our number saved in their phones.
