How Hollis Air Duct Cleaning Was Born
Back in 2004, Roy Castellanos was working alongside a small crew in Los Angeles when he kept running into the same story at house after house. Homeowners would open the door, point toward the vents, and hand over a flyer from some company that had quoted one price over the phone. Then the van would pull up, the crew would poke around for ten minutes, and suddenly the “simple cleaning” became an urgent upsell for mold treatment, new ductwork, or a sanitizer that nobody asked for. The final invoice rarely matched the phone quote. Roy watched a woman in the San Fernando Valley pay triple what she had agreed to, and something in him shifted. He did not want to be associated with that kind of work anymore.
So he started Hollis Air Duct Cleaning with a simple promise: the price you hear before the work starts is the price you pay when the work is done. No surprises, no last-minute add-ons, no pressure. What began as one local operation in Los Angeles has grown into a network of independently owned locations across the country, each one held to the same standard. The mission has not changed since that first year: cleaner air, from the vents on out.
Roy Castellanos’s Personal Connection to the Air Duct Cleaning Trade
Roy Castellanos did not grow up dreaming about air ducts. Nobody does. He got into this work the way most people get into honest trades: he showed up, watched carefully, and discovered that the job mattered more than he expected. Early in his career, he shadowed a tradesman who had been cleaning ducts for longer than Roy had been alive. That man taught him to look at a return register the way a mechanic listens to an engine. He would press his ear near the metal, listen for the whistle of air fighting through a clogged filter, and then explain exactly what was happening inside the walls of the house.
The first time Roy pulled a register cover off and shined a light into a duct that had not been cleaned in twenty years, he remembers the smell more than the sight. A stale, musty, slightly sour odor that had been circulating through that family’s living room every time the furnace kicked on. They had been breathing it for years without knowing why the house always felt heavy. When the job was done and the air moving through those rooms felt lighter, the homeowner stood in the hallway and just took a deep breath. That moment stayed with Roy. Not because of the equipment or the technique, but because something small and invisible had been making a family’s home feel wrong, and fixing it changed how that home felt.
That is what gets him out of bed at the start of a workweek. Not the machinery, not the invoice, but the difference between a house where the air feels stale and a house where it feels clean. If Roy were not in this trade, he would probably still be working with his hands somewhere. Maybe restoring old cars, or fixing things that other people had given up on. But he found his place in air ducts, and after more than two decades of living this work, he still talks about it the way a craftsman talks about his trade: with respect for the details and impatience for anyone who cuts corners.
Meet Roy Castellanos – The Person Behind Every Job
Roy Castellanos is the Owner and Founder of Hollis Air Duct Cleaning. He built this company from the ground up, starting in Los Angeles and expanding into a national network of independently owned locations that operate under the same name and the same standard. Roy has spent more than twenty years in the trade, learning it from the filter side out. He has trained on professional-grade equipment from brands like Nikro and Abatement Technologies, and he knows the difference between a job done fast and a job done right.
What separates Roy from a technician who just rolls a machine into your hallway is accountability. His name is on the business. When the work does not meet the standard, it reflects on him personally, and he does not take that lightly. Outside of work, Roy is a creature of habit: coffee early, a long drive with the window down, and a deep respect for people who say what they mean and do what they said. His commitment to every homeowner is the same one he made in 2004: a written price before any work starts, and work that holds up after the van leaves the driveway.
Our Promise to Homeowners
Every Hollis Air Duct Cleaning location operates under The Garrison Code. These are not slogans on a poster. They are the five rules that every independent owner agrees to before they put the Hollis name on the side of a van. We show up inside the window we gave you. We put the price in writing before any work starts. We do it by the book, the first time. We leave the site clean and squared away. And we stand behind the work for a full year.
That last one has teeth. If the cleaning fails within that year, we come back and make it right at no charge. That is The Garrison Standard, and it is the reason we do not bait customers with a low phone quote only to inflate the price at the door. The price is the price. The work is the work. And it is all written down before a single register is pulled.
Our Credentials
- State-licensed: Every pro working under our name is required to hold the license their state requires.
- Insured and bonded: We carry the coverage that protects your home and our crew while we are on the job.
- More than two decades in the trade: Founded in 2004, we have been cleaning residential air systems for over twenty years.
- Professional equipment: We use commercial-grade tools from Nikro, Honeywell, and Abatement Technologies.
- The Garrison Standard: Every job is covered in writing for a full year.
Why does any of that matter to you? Because when you let a crew into your home, you are not just buying a service. You are trusting strangers to work inside the walls you live in, around the air your family breathes. A state license means the person on site knows the local code. Insurance and bonding mean that if something goes wrong, you are not left holding the bill. And a written guarantee means we have no reason to cut corners. We would only be creating more work for ourselves.
Rooted in the Communities We Serve
Hollis Air Duct Cleaning got its start in Los Angeles, and that city is still part of our story. But today we are a national network with locations serving homeowners across the country, from Los Angeles and San Diego to Houston, Dallas, Austin, Fort Worth, San Antonio, Jacksonville, Philadelphia, Brooklyn, Queens, and Manhattan. Each location is independently owned and operated by someone who lives and works in their own region. They are not a franchise template. They are local businesses that agreed to work to The Garrison Standard, and that combination is what makes the Hollis name mean something.
