What Alpharetta Homeowners Say About Hollis Air Duct Alpharetta
Reviews tell you what actually happens when the van pulls up and the work begins. Not the sales pitch, not the website copy. We know that. That’s why every Hollis Air Duct Alpharetta job is built the same way: a written price before anything starts, a background-checked technician in uniform, and a 365-Day Done Right Promise in writing before we leave. The comments below come from homeowners around Alpharetta, Milton, Roswell, and Johns Creek who hired us for air duct cleaning, dryer vent cleaning, and duct sealing. They wrote what they wrote. We just fixed their air.
Recent Reviews
“We had the ducts cleaned in a 2004 house off Windward Parkway that had never been touched. The Nikro negative-air machine pulled out a layer of dust I didn’t want to believe was in there. The technician showed me before-and-after photos of the return plenum before he packed up. Price was exactly what the written quote said.”
Kristen M., Windward, Alpharetta
“The dryer vent was backing up every cycle and the laundry room smelled like burnt lint. Roy’s technician ran a rotary brush through the whole run, pulled out a clog the size of a softball, and sealed the joint where it had been leaking. Dryer runs quiet now. Took about an hour from door to door.”
Nia B., Crabapple, Milton
“They explained the difference between a $99 bait-and-switch duct cleaning and a real one. The price we agreed to on the phone was the price on the invoice. Same number. That never happens with home service companies. The tech wore a company uniform, had ID, and set drop cloths under every register.”
Wade B., Downtown Alpharetta
“We bought a house in Halcyon where the previous owners had two big dogs. Every register was caked with hair and the AC coil was filthy. Hollis did a full negative-air cleaning, replaced the filter media, and the airflow difference was noticeable the first night. They wrote the 365-Day Done Right Promise on the work order without me asking.”
Steve M., Halcyon, Alpharetta
“Called on a Tuesday about a musty smell coming from the vents whenever the AC kicked on. The person who answered the phone was a real human, not a queue. They scheduled me in, showed up inside the window, and found a disconnected return duct in the crawlspace pulling in humid air. Sealed it with mastic, cleaned the system, and the smell was gone by the next morning.”
Kristen M., North Alpharetta
“I didn’t know duct sealing was a thing until the tech showed me the gaps with a smoke pencil. We were losing cooled air into the attic all summer. After they sealed the trunk line and boots, the upstairs bedroom finally holds temperature. They finished in one afternoon and left zero mess. Vacuumed the hallway before they left.”
Nia B., City Center, Alpharetta
Why Customers Trust Us
The pattern across those reviews is not an accident. It’s the Garrison Code, the operating standard every Hollis location follows: arrive inside the quoted window, put the price in writing before work starts, complete the job by the book, and leave the site clean. No exceptions, no judgment calls. What that means for you in Alpharetta is straightforward. You know the technician’s name before he walks in. You know the dollar amount before he touches a vent. And you have the 365-Day Done Right Promise in writing: if the work fails within a year, we come back at no charge, including a free second visit. That’s the guarantee, and it’s not a line on a website. It’s on your work order.
Roy Castellanos, the owner of Hollis Air Duct Alpharetta, built the local operation around professional-grade equipment, Rotobrush rotary brush systems, Nikro negative-air machines, filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman, and the simple discipline of writing down the price before the work begins. That combination is why the reviews above read the way they do. If you’re in Alpharetta, Milton, Johns Creek, or Roswell and your ducts have not been cleaned in years, or you suspect your dryer vent is clogged, call (762) 769-7145. A live person answers. You’ll get a straight answer and a written price. No faint promises, no pressure.
