How Hollis Air Duct Henderson Was Born in Henderson
By 2004, the air duct cleaning industry had a reputation problem, and Henderson homeowners were feeling it. Roy Castellanos kept hearing the same story from neighbors across Green Valley and Whitney: a company would advertise one price, then the technician would arrive and suddenly find mold, extra vents, or a “system upgrade” that tripled the invoice. People weren’t angry about the work. They were angry about the game.
Roy had worked in home services long enough to know how trades should run. Show up when you say you will. Put the number in writing before touching anything. Do the job right and stand behind it. That wasn’t complicated, but it wasn’t common. When the opportunity came to bring Hollis Air Duct Cleaning to Henderson, Roy didn’t see it as opening another branch. He saw it as giving his neighbors what they’d been asking for: an air duct company that ran on discipline instead of upsells.
What makes this branch different isn’t a slogan. It’s how the work is run. Every job gets a price in writing before anything starts, and every job is covered by The Garrison Standard, the code of conduct from the Garrison Partners family that Hollis is part of. Roy leads the local team that carries that standard into homes from Anthem to Boulder City. The company name was already established. The promise to Henderson was his to keep.
Roy Castellanos’s Personal Connection to the Air Duct Cleaning Trade
Roy Castellanos didn’t grow up dreaming about air ducts. He grew up with a respect for work you can see and touch, the kind where a job is either done right or it isn’t. Early in his career, he took a job helping clean ductwork in an older home off Sunset Road. The homeowner had been told by a previous company that the system was clean. Roy’s inspection told a different story. The return ducts were lined with years of dust, pet hair, and what looked like construction debris from the original build.
He still remembers the smell when the agitation equipment first kicked on: stale, warm, faintly sour, like a closet that hadn’t been opened in years. And he remembers the look on the homeowner’s face when the before-and-after photos came back. The air in that house smelled different within a day. The homeowner’s daughter, who had been wheezing at night, slept through the night for the first time in weeks. Roy doesn’t tell that story to sell duct cleaning. He tells it because it changed what the work meant to him.
Before that job, cleaning ducts was maintenance. After it, he understood that the air inside a home is something families live in every hour. That’s what gets him out of bed on a Monday morning: the knowledge that a system cleaned properly today means easier breathing for a family tonight. If he weren’t doing this, Roy figures he’d still be in the trades somewhere, maybe framing houses or running a service crew. But he wouldn’t be doing anything where the result is invisible in the best way, where the proof isn’t a finished surface but the quality of the air itself.
The training under the Hollis name uses tools built for the job, like Rotobrush and Nikro systems that agitate and extract rather than just vacuum. Roy learned to read a system the way a mechanic reads an engine: the size of the return, the condition of the coil, the filter path, the telltale signs of a rushed job by someone else. More than a decade of that work has given him a habit he can’t switch off. When he walks into a home, he notices the way the air feels on his skin and whether the registers are coated in dust. It’s not a job. It’s how he sees a house now.
Meet Roy Castellanos – The Person Behind Every Job
Roy Castellanos is the Owner and Founder of the Henderson branch of Hollis Air Duct Cleaning. He’s spent more than a decade working in home services, with years of hands-on experience specifically in air duct cleaning and residential ventilation. His training covers the full scope of duct system work: inspection, agitation and extraction cleaning, contamination control, and system reassembly done to manufacturer specification.
What separates Roy from the technician who shows up in a corporate van with a script to hit is simple: he’s accountable to the person standing in the driveway. He runs a local team that answers to the standards of The Garrison Code, which means showing up inside the window given, pricing in writing before any work starts, doing the job by the book the first time, leaving the site clean, and standing behind the work for a full year. Roy takes the time to walk homeowners through what he found, what he did, and what he photographed. On weekends, you’ll find him working through a home renovation project of his own, which keeps him honest about what “squared away” means. He’s committed to one thing above everything else: when he leaves your home, the air coming out of those vents is cleaner than when he arrived.
Our Promise to Henderson Homeowners
The promise behind Hollis Air Duct Henderson isn’t a list of adjectives. It’s a set of rules we follow on every job.
Price in writing before any work starts. You’ll know the full cost of your duct cleaning before a single tool leaves the van. No surprises at the door, no last-minute “extras” discovered once the technician is inside.
Do it by the book, the first time. We don’t rush. The system gets cleaned the way NADCA guidelines describe, with agitation and extraction that removes debris rather than just loosening it.
Leave the site clean and squared away. Floors protected, registers put back, furniture restored to where it was. You shouldn’t have to clean up after a cleaning.
Stand behind the work for a full year. If the system has a problem within that year related to our cleaning, we come back and make it right at no charge. That’s The Garrison Standard, and it’s in writing.
Our Credentials
- State-licensed: Every pro working under our name is required to hold the license and insurance their state requires.
- Insured and bonded: Required coverage for every job, not optional.
- Experienced local team: Roy has been in home services and air duct work for over a decade, and the team is trained on the equipment we use every day: Rotobrush and Nikro agitation and extraction systems, plus Honeywell and Aprilaire filtration components when a system calls for them.
- Strong local reputation: Built one job at a time, through referrals from homeowners across Henderson, Green Valley, and Anthem who know what reliable work looks like.
Why any of this matters when you’re deciding who to let into your home: a license means the person in your hallway has met the state’s minimum bar for training and accountability. Insurance means you’re not left holding the bag if something goes wrong on the job. Experience means the technician has seen enough systems to know what’s normal and what’s not. And a reputation built through local referrals is something no advertisement can fake.
Rooted in Henderson
Hollis Air Duct Henderson doesn’t pretend to be from every town. This branch is an independent local business that agreed to work to The Garrison Standard, and Henderson is the only place it calls home. Our service area stretches from Green Valley and Anthem through Paradise, Whitney, and Enterprise, out toward Boulder City and into Spring Valley and Sunrise Manor. Roy knows these neighborhoods the way a local does: which communities see more construction dust from new builds along the St. Rose corridor, which older homes in Henderson’s original grid have tighter returns that need more careful cleaning, and how a dust-heavy month like July affects systems around the McCullough Range.
The name Hollis is an old surname with an airy, open sound, fitting for a company whose entire job is the air moving through your home. That air, and the people breathing it in Henderson, is what this branch works for every day.
