How Hollis Air Duct Pasadena Was Born in Pasadena
When Hollis Air Duct Cleaning decided to open a Pasadena branch, it wasn’t a boardroom decision. It was a response to what we kept hearing from homeowners across the San Gabriel Valley. People were tired of calling air duct companies that never showed up on time, quoted one price over the phone and another at the door, and left attics looking worse than when they arrived. Pasadena deserved better than that, and the brand’s whole reason for existing is cleaner air, from the vents on out. So the Pasadena branch was opened to bring The Garrison Standard to this city: a written price before any work starts, a crew that arrives inside the window they gave, and a one-year written guarantee on every job. Roy Castellanos was asked to lead the local team, and from day one, the focus has been simple: do the work the way you’d want it done in your own home. That’s still how this branch operates today.
Roy Castellanos’s Personal Connection to the Air Duct Cleaning Trade
Roy Castellanos didn’t grow up dreaming about air ducts. Nobody does. But he did grow up in a house where dust was a constant battle. His family home sat near a busy stretch of Pasadena, and every few weeks, a fine layer of grit would settle on the windowsills, the bookshelves, the top of the refrigerator. The air just felt heavy. Back then, nobody talked about what was inside the ductwork. You just dusted more and opened a window and lived with it.
The first time Roy climbed into an attic to inspect a duct system, he understood what was happening in homes like the one he grew up in. Years of dust, pet hair, and construction debris had packed the inside of those ducts. The system was running harder than it needed to, pushing that same recycled air through every room. It smelled stale. It looked worse. And the homeowner had no idea because nobody had ever shown them.
That’s what stuck with him. Not the tools, not the technique. It was the look on a homeowner’s face when they saw what had been hiding inside the vents they’d been breathing through for years. That moment of recognition matters. It’s why Roy has spent more than a decade in this trade, learning how different systems behave in different homes, how older Pasadena bungalows differ from newer builds in Arcadia or Monrovia, and how to leave every job site clean, squared away, and better than he found it. He doesn’t see this as a duct cleaning job. He sees it as giving a family back the air in their own home.
If he weren’t doing this work, Roy would still be working with his hands. He’s the kind of person who takes something apart just to understand how it works, then puts it back together better than before. That instinct serves every homeowner who calls this branch.
Meet Roy Castellanos – The Person Behind Every Job
Roy Castellanos is the Owner & Founder of this Hollis Air Duct Cleaning branch in Pasadena. He came into the trade with a background in hands-on service work and has spent his career learning the details of residential duct systems, airflow, and filtration. Roy leads a local team that works to The Garrison Code: show up inside the window we gave, 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.
What sets Roy apart from a corporate franchise technician is that he’s here. He lives in this community, he knows these neighborhoods, and he takes the condition of this branch’s work personally. Off the clock, Roy is the kind of person who can’t leave a project half finished, whether it’s in a customer’s attic or his own garage. That trait carries into every job this Pasadena branch takes on.
Roy’s commitment is simple: every homeowner who calls (626) 469-5477 gets honest answers, a written price, and work done right the first time.
Our Promise to Pasadena Homeowners
Every job starts with a written price. No surprises at the door, no prices that move once the van pulls up. That’s a Garrison requirement, and it’s one of the main reasons this branch was brought to Pasadena.
We do the job by the book. We use tools built for the trade, like Rotobrush and Abatement Technologies equipment, and we follow the process from start to finish without cutting corners. We don’t rush through a home just to get to the next one.
We stand behind the work for a full year. If something fails in that time, we come back and make it right at no charge. That’s the Garrison Standard, and it’s in writing on every job.
