How Hollis Air Duct Dallas Was Born in Dallas
We didn’t bring Hollis to Dallas on a whim. We brought it here because Dallas homeowners kept telling us the same story, and after a while, you can’t unhear it. A neighbor in Lake Highlands paid a lowball price over the phone, then watched the invoice triple once the tech opened the return vent and found “mold.” A family in Richardson got a living room full of dust two days after a crew claimed the system was spotless. A landlord in Garland showed us photos of the same duct run, before and after, where the after looked exactly like the before. These weren’t isolated incidents. They were the pattern. Our branch of the Hollis network exists to break it in Dallas specifically, because this market, with its long pollen seasons, clay-heavy construction dust, and older homes with trunk lines nobody has seen in decades, deserves better than bait-and-switch pricing and a fog machine and a goodbye.
When the opportunity came to open this branch under the Garrison Partners family of brands, the decision was easy. The platform already had the discipline we wanted: written pricing before any work starts, a full-year guarantee in writing, crews trained to a standard instead of a script. Our job was to build the Dallas team and run it the way we’d want a crew to show up at our own homes in Rowlett or DeSoto. We opened this location to serve Dallas, Garland, Richardson, and the surrounding communities, and from the first job, the promise hasn’t moved: cleaner air, from the vents on out, done by the book, with a price in writing first. That’s what Dallas was missing, and that’s what we’re here to deliver.
Roy Castellanos’s Personal Connection to the Air Duct Cleaning Trade
Roy Castellanos came into this trade the long way, and it changed how he sees a house forever. Early in his career, he spent time in attics and crawl spaces on jobs that had nothing to do with duct cleaning, but the ducts were always right there, running overhead like the home’s quiet circulatory system. The first time he opened a return plenum in a home that hadn’t been cleaned in the better part of a decade, he remembers the smell distinctly: a dry, musty, slightly sweet odor, the smell of condensed years. The filter slot was packed with a gray felt of dust and pet hair. The coil downstream was wearing a sweater of grime that was cutting airflow and forcing the system to work harder, cooling less, and cycling more. He stood there and realized most homeowners never see any of this. They change the filter, they vacuum the registers, and they assume the inside is clean because nobody ever tells them otherwise.
That experience stuck. He started learning the right way to clean duct systems: negative pressure, proper agitation, the difference between brushing a plenum and just vacuuming the first few feet of a run. He learned how much of the visible dust in a home actually comes from the duct system stirring things up, and how much of the allergic misery in spring comes from what’s already living in the trunk lines. The trade gave him something concrete: a problem you can see, a fix you can perform, and a result you can photograph and hand to the customer. There’s a satisfaction in that, and it’s personal. What gets Roy out of bed is the knowledge that somewhere in Dallas there’s a family breathing easier because a crew he trained did the job the way it’s supposed to be done. If he weren’t doing this, he’d probably be doing something else with his hands, building or fixing things, because the core of the work is the same: understand how a system works, find what’s broken or dirty, and leave it better than you found it.
Meet Roy Castellanos – The Person Behind Every Job
Roy Castellanos is the Owner & Founder of Hollis Air Duct Dallas, the local branch that brings The Garrison Standard to homeowners across Dallas and its neighboring communities. He leads the team that services Dallas, Garland, Richardson, Rowlett, Heath, DeSoto, Red Oak, Highland Park, Sachse, Oak Lawn, Murphy, and Lake Highlands. Roy’s background is in working with his hands and in managing teams that respect a customer’s home. What sets him apart from the franchise technician who flies through a rotation of preset appointments is accountability. When a crew under Roy’s name walks into a home, the job is done the way he’d want it done in his own. He’s the kind of person who rechecks his own work and expects his crew to do the same. And if something isn’t right, he wants to hear about it, because standing behind the work is the only part of the job that matters at the end of the day.
Our Promise to Dallas Homeowners
Every job follows the same code, and we call it The Garrison Code. It’s five rules, and we don’t bend them. Show up inside the window we gave you. Price in writing before any work starts. Do it by the book, the first time. Leave the site clean and squared away. And stand behind the work for a full year. That last one isn’t a slogan. It’s a written guarantee on every job, and if something fails within that year, we come back and make it right at no charge. We know Dallas homeowners are tired of no-shows and prices that move at the door. Our pricing is one flat price per system, agreed before work begins, so the number you approve is the number you pay. No per-vent upsells. No surprise add-ons. Just cleaner air, from the vents on out.
Our Credentials
Hollis Air Duct Dallas operates to the standards that Garrison Partners requires of every local branch:
- State-licensed: Every pro working under our name is required to hold the license their state requires.
- Insured & bonded: Every pro working under our name is required to carry the insurance and bonding their state requires.
- Years of local experience: This branch has served Dallas and the surrounding communities with a focus on doing the job right, not fast.
- Strong local reputation: Homeowners across Dallas, Garland, Richardson, and the surrounding areas know us for showing up inside the window we gave and putting the price in writing first.
Why does this matter to a homeowner hiring someone to work inside their home? Because you’re letting a stranger into your house, often into your attic or crawl space, to touch the system that moves the air your family breathes. A license means they’ve met the state’s baseline for competence. Insurance and bonding mean you’re protected if something goes wrong. And a local reputation means you can ask a neighbor in Oak Lawn or Sachse about us and get a straight answer.
Rooted in Dallas
We work in Dallas, not just around it. Our crew members know that Lake Highlands has older trunk lines that need patient, thorough cleaning. They know DeSoto and Red Oak see heavy pollen in spring, and that Highland Park homes often have systems jammed into tight mechanical closets that require careful access. We know the way construction dust from new builds in Murphy and Sachse settles into ductwork and lingers. The Hollis name is part of the Garrison Partners family, and each location is an independent local business that agreed to work to The Garrison Standard. Garrison Partners doesn’t pretend to be from every town. But we are from here, and we service this area with the kind of local knowledge a call center a thousand miles away can’t offer.
