What Hempstead Homeowners Say About Hollis Air Duct Hempstead
We don’t ask for reviews because it looks good on a website. We ask because the work we do is invisible by nature. You can’t see inside your own ductwork, so the only way a Hempstead homeowner knows the job was done right is if someone they trust tells them, or if the proof shows up in the photos we take before and after. The comments below come from people who called (516) 559-4917, got a written price before any work started, and then watched our technicians follow The Garrison Code on the job: arrive inside the window, work by the book, leave the site clean. Roy Castellanos has been running things here in Hempstead since 2004, and the standard hasn’t slipped.
Recent Reviews
We bought a 1950s colonial near Hofstra and the previous owner had two German shepherds. The air in the bedrooms never smelled right, no matter how much we cleaned. The crew from Hollis ran a camera through the returns first and showed us what was actually inside. Three hours later, the air felt different. They left photos of every section they cleaned, including the trunk line under the hallway. That’s the part other companies skip.

My daughter’s allergies were waking her up every night. We called Hollis on a Tuesday morning, someone answered right away, and Roy had a technician out that week. The tech explained the negative-air method in plain English: the machine creates suction so dust doesn’t blow back into the house while the rotary brush knocks everything loose. We watched the filter on the machine fill up with gray dust. That was our dust. It’s gone now.

I’ve been a landlord in Hempstead for over a decade and I’ve used a few duct cleaners over the years. Hollis is the only one that handed me a written price before the job and stuck to it. No per-vent upcharge, no surprise fee for the second return. The technicians were in uniform, background-checked, and they covered their shoes before walking on the carpet. My tenant said the place smelled like a new apartment afterward.

The dryer vent was so clogged the dryer took two full cycles to finish a load of towels. Hollis cleaned the vent from the dryer all the way to the exterior cap on the side of the house. They showed me the lint they pulled out, and it filled half a garbage bag. My dryer works like it did when it was new, and I’m not constantly worried about a fire starting behind the wall.

We had our ducts sealed after the cleaning because the airflow to the upstairs bedrooms was basically nonexistent. The technician found gaps in the duct joints in the basement and sealed them with mastic. Within a day we could feel air moving through the upstairs vents. The written quote covered everything, and the 365-Day Done Right Promise was in writing. Nobody else in Hempstead offered that.

What sold me was the phone call. I called three companies. Two sent me to voicemail. Hollis answered on the second ring, asked about the size of my house and how long it had been since a cleaning, and gave me a price range right there on the phone. When the technician arrived, the final written price was inside that range. No games, no bait and switch. The air in my living room doesn’t have that stale smell anymore.

Why Customers Trust Us
Every review above points to the same few things: a written price before anything starts, technicians who show up on time and act like guests in your home, and work you can verify with your own eyes. That verification matters. We photograph the inside of your ducts before and after, so you see exactly what we removed and exactly what got cleaned. We use Rotobrush rotary brush systems and Nikro negative-air machines, the same professional-grade equipment commercial crews use, because a shop vac and a prayer don’t clean ductwork. Filter options from Honeywell, Aprilaire, Abatement Technologies, and Guardsman are available if your system needs better filtration after the cleaning.
And then there’s the 365-Day Done Right Promise. It’s not a slogan. It’s in writing on every job: if the work fails within a full year, Hollis returns at no charge. That includes a free second visit. No renegotiation, no fine print, no “well, that’s technically outside the warranty.” Roy Castellanos put his name on this company and this promise. That’s what the reviews are really about. If your Hempstead home needs duct cleaning, dryer vent cleaning, or duct sealing, call (516) 559-4917. You’ll speak to a live person, get a straight answer about pricing, and know exactly who is walking through your door.
