Why Hempstead Homeowners Choose Hollis Air Duct Hempstead for Air Duct Cleaning
Homeowners across Hempstead keep coming back to us because we do the job the way it should have been done the first time. We show up inside the window we scheduled, put the price in writing before anything starts, and stand behind the work for a full year under The Garrison Standard. Roy Castellanos leads our Hempstead team with the same discipline the Hollis name has carried since 2004. That combination of local accountability and a proven national standard is what separates us from the one-truck operations and the companies that disappear after the invoice clears.
6 Reasons We’re Hempstead’s Top Air Duct Cleaning Company
1. Experience That Shows Up at Your Door
Hollis Air Duct Cleaning has been doing this work since 2004, and the Hempstead branch carries that experience into every home we visit. Our team has cleaned ducts in every kind of house Nassau County throws at us, from the 1920s colonials near Hofstra to the split-levels in Uniondale and the newer construction near Levittown. That range matters because duct layouts, age of the system, and the way a house settles all change how the cleaning should be done. We’ve seen the shortcuts that leave dust behind, and we don’t take them.
2. A Reputation Built on Showing Up and Doing It Right
The Hempstead area is a word-of-mouth market, and our reputation here has been earned one job at a time. Homeowners in Flushing, Jamaica, Massapequa, and Oceanside have trusted us because we arrive when we say we will and we deliver what we promised. Talk to neighbors who have used us and you’ll hear the same things: clean work, a fair price that didn’t change, and a crew that respected their home. That consistency is not an accident. It’s the standard we agreed to when this location joined the Hollis family.
3. Licensed and Insured, the Way It Should Be
In New York, any contractor working in your home should be able to show credentials, and everyone who carries the Hollis name is required to hold the licensing and insurance their state requires. We never send anyone into a Hempstead home who cannot verify that coverage. It protects you, and it protects the work. Before you let anyone near your furnace or air handler, ask to see their paperwork. We’re ready to show ours.
4. Real Equipment and Recognized Brands
We don’t run a vacuum hose off a shop vac and call it duct cleaning. Our crews use professional equipment from names like Nikro and Abatement Technologies, gear built specifically for HVAC system cleaning, not homeowner hardware. A Nikro negative air machine or a properly configured Abatement Technologies setup pulls contaminants out of the ductwork rather than just loosening them and letting them resettle. That difference is one reason our work holds up over time instead of looking dusty again in a month.
5. Transparent Pricing in Writing, Every Time
This is where Hempstead homeowners have been burned before: a low teaser price that balloons once the crew is in the driveway. We do it differently. You get a written price before any work starts, and that price is what you pay. It’s one flat price per system, not a per-vent charge that adds up fast. If the scope changes, you’ll know before we touch a tool. That’s The Garrison Code at work: price in writing before any work starts. No games, no moving numbers.
6. The Garrison Standard: A Full-Year Written Guarantee
Every Hollis location, including ours in Hempstead, works under The Garrison Standard. Here’s what that means in plain language: we arrive inside the window we gave you, we price the job before we start, we do the work by the book, and we leave the site clean and squared away. Then we put the guarantee in writing for a full year. If the work fails in that time, we come back and make it right at no charge. That’s not a slogan. It’s the promise stamped on every job we do.
Our Promise to You
When you book Hollis Air Duct Hempstead, you’re getting a straight deal. We arrive inside the window we scheduled, not somewhere in a four-hour gray zone. You get a written price for the whole system before we start, and that number does not move unless the scope changes and you approve it first. Our crew does the work by the book, using professional equipment and taking the time to do it correctly rather than rushing the job. When we leave, the site is clean and your system is documented with before-and-after photos so you can see exactly what was done. And if anything fails within a year, we return and fix it. No charge, no argument. That’s what we mean when we say disciplined, squared away, and accountable.
Frequently Asked Questions
Because we’re a local Hempstead business held to a national standard. Roy Castellanos runs a team that lives and works in this community, so reputation matters to us in a way it doesn’t to a fly-by-night operation.

Yes. Everyone operating under the Hollis name is required to hold the licensing and insurance their state requires, and that applies to our Hempstead team.

It’s a reasonable thing to ask of any contractor you let into your home, and we treat that request as a sign of a smart homeowner, not an inconvenience.
