AfterSupply Duct Cleaning in Henderson, NV
Our Air Duct Cleaning services in Henderson typically cost $285 to $540 for a full home, runs two to four hours, and clears out years of dust, pet dander, and construction debris from the ducts that carry heated and cooled air into your rooms. We’re Hollis Air Duct Henderson, and we’ve been doing this since 2004 under the Garrison Standard. Call (775) 383-5847 and we’ll give you a written price before any work starts.
Your home’s ductwork has two halves. Return ducts pull air back to the furnace or air handler. Supply ducts push conditioned air out to every room. When supply ducts load up with dust and debris, they blow that material directly into the air your family breathes. Drapes get dusty two days after you clean. Tabletops film over. The rooms farthest from the unit start feeling stuffy because the air is fighting through a layer of grit to reach you. That’s what supply duct cleaning addresses. If you want a broader picture of the full system, read our Air Duct Cleaning in Henderson page for how supply, return, and plenum work together.
When You Need Supply Duct Cleaning
Most Henderson homes need supply duct cleaning every three to five years. Here’s what tells you it’s time sooner:
- Dust settles on surfaces within a day or two of cleaning. The supply registers are blowing fine particles into the room every time the system cycles on.
- Some rooms stay warm in summer or cold in winter. Restricted supply ducts mean less conditioned air reaches the far end of the house. We see this often in Green Valley Ranch and Anthem homes where long supply runs accumulate buildup.
- You renovated recently. Drywall dust, sawdust, and sanding grit get pulled into the system and pushed back out through supply registers. In Henderson’s post-2020 building boom, we clean a lot of recently remodeled homes in Inspirada and Cadence.
- Your HVAC system was replaced but ducts weren’t touched. Old supply ducts often sit caked with years of debris while the new unit pushes air through them. The new equipment can’t fix dirty ductwork.
- Allergy symptoms flare up indoors. Henderson’s desert air means we seal our homes tight against heat and dust, but that also traps whatever’s circulating inside the supply ducts.
- Visible dust or debris at supply registers. Grab a flashlight. If the inside of the register boot looks fuzzy or caked, the ducts behind it are worse.
Our Supply Duct Cleaning Process
Here’s exactly how we work, step by step. Same process every time, on every home, with no shortcuts.
- Inspection and written price. We walk the system with you before touching anything. Count the supply runs, check access points, show you what we’re seeing at a couple of registers. Then we put the total price in writing. That number doesn’t move at the door.
- Protect the home. We lay corner guards along floor paths from the entry to the equipment, cover the work area at the furnace or air handler, and use shoe covers inside. The Garrison Code covers this: leave the house as clean as we found it.
- Connect the negative-air machine. A Nikro negative-air unit hooks to the supply plenum and puts the entire supply system under continuous vacuum. This creates negative pressure, which means anything we loosen gets pulled out of the duct, not pushed into your living space.
- Agitate each supply run. We push a rotating brush or high-pressure air whip through every supply duct, one run at a time, from the register boot back to the plenum. This knocks loose adhered dust, pet dander, and the fine film that builds on duct walls. The vacuum pulls all of it to a HEPA-filtered collection point.
- Clean registers, boots, and plenum. We remove and clean each supply register, wipe out the boot, and clear the supply plenum at the equipment. If you have Aprilaire or Honeywell filtration media, we check it and note condition so you’re not guessing about filter life.
- Final walkthrough. We walk the home with you, show you the debris we collected, and confirm every register is seated back in place. The price you were quoted is the price on the invoice. If anything isn’t right, you call us within 365 days and we come back at no charge.
Supply Duct Cleaning Pricing in Henderson
Here’s How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Henderson, NV based on real supply duct cleaning costs right now, based on the homes we service across the valley.
| Home Size | Typical Supply Duct Cleaning Price |
|---|---|
| Up to 1,500 sq ft | $285 to $375 |
| 1,500 to 2,500 sq ft | $350 to $475 |
| 2,500 to 3,500 sq ft | $425 to $540 |
| Over 3,500 sq ft | Quoted after inspection |
What moves the number:
- Number of supply runs. A 12-run system costs more than a 6-run system because each one gets individually agitated and vacuumed.
- Access. Henderson homes built on slab with ducts in the attic or crawlspace can take longer than homes with basement access. Attic work in July is tough on the tech, but the price stays what we wrote down.
- Buildup severity. Renovation dust or years of pet hair may require a second pass on some runs. We tell you before, not after.
- Registers and boots condition. Rusted or damaged boots at the register may need replacement. We show you what we see and price any add-on separately, in writing, before proceeding.
Every supply duct cleaning quote includes the same 365-Day Done Right Promise. If anything we cleaned starts causing a problem within a year, we come back and make it right at no charge. That’s not a verbal promise, it’s on the invoice. Free estimates, no door-pressure tactics, and a live person answers the phone around the clock at (775) 383-5847.
FAQs – Supply Duct Cleaning
How much does supply duct cleaning cost in Henderson?
Supply duct cleaning in Henderson runs $285 to $540 for most homes, though larger two-story homes over 3,500 square feet are quoted after a Video Inspection. The main drivers are the number of supply runs, access difficulty, and how much buildup is inside. Call (775) 383-5847 and we’ll give you a written quote that doesn’t move at the door.
Can you clean only the supply ducts and not the return ducts?
Yes, but we rarely recommend it. The supply and return sides of your system share the same air handler, so debris from a dirty return gets pulled through the equipment and pushed right back into the supply side. Most Henderson customers get better, longer-lasting results cleaning both at once. Roy Castellanos, who runs Hollis Air Duct Henderson, will show you what’s in each side before you decide.
How long does supply duct cleaning take?
Most Air Duct Cleaning Near Me in Henderson, NV jobs take two to four hours for supply duct cleaning, depending on run count and buildup. We quote within an arrival window, show up inside it, and clean up the work area before we leave.
Is supply duct cleaning worth it if I have a good filter?
A good Aprilaire or Honeywell filter protects your equipment, but it can’t remove debris that’s already adhered inside your supply ducts. Once buildup is in the duct, it stays there until it’s physically agitated and vacuumed out. That’s the work a negative-air machine and rotary brush system do together.
