Why Alpharetta Homeowners Choose Hollis Air Duct Alpharetta for Air Duct Cleaning
Most Alpharetta homeowners call us after a bad experience with a no-show or a price that changed once the crew walked in the door. That frustration is exactly what our process was built to eliminate. Since 2004, Hollis Air Duct Cleaning has held every location to The Garrison Standard: price in writing before work starts, arrival inside the window we gave, and a full-year written guarantee on the work. Roy Castellanos runs the Alpharetta branch, and he keeps the team here honest on all of it.
6 Reasons We’re Alpharetta’s Top Air Duct Cleaning Company
1. Decades of Trade Experience Behind Every Job
Hollis Air Duct Cleaning has been doing this work since 2004, which means the brand has seen every duct configuration, every furnace pairing, and every layer of Georgia pollen a system can collect. That experience gets passed down through training and through the standards every branch follows. You are not getting a rookie guessing at your return chase; you are getting a process refined over more than two decades.
2. A Strong Local Reputation in Alpharetta and North Fulton
We know homeowners here talk, and in neighborhoods like Windward, Crabapple, and downtown Alpharetta, reputation spreads fast. The strongest proof we can point to is repeat business and referrals: homeowners in Milton, Johns Creek, Roswell, and Cumming keep recommending us to their neighbors. When someone lets you into their home and then tells their friend to do the same, that says more than any ad ever could.
3. Licensed, Insured, and Held to a Written Standard
Every professional working under the Hollis name is required to hold the license and insurance their state requires. Beyond that, our Alpharetta team works under The Garrison Code, which means no shortcuts, no half-finished returns, and no leaving a mess behind. We don’t ask you to take that on faith; every job gets a written scope of work before anything starts, so you know exactly what you’re paying for.
4. Brand-Name Equipment and Real Trade Knowledge
Our crews run Rotobrush and Nikro systems, the same tooling used by commercial and residential pros across the country, and we know how to work with whole-home systems that include Honeywell filtration and Aprilaire media cabinets. That matters because the wrong tool in a flexible duct down in a finished basement can tear a liner, and a torn liner means air you paid to condition is leaking into your crawlspace. We know the difference, and we bring the right equipment for the job.
5. Pricing in Writing Before Any Work Starts
You will never get a per-vent price from us that doubles once the truck pulls up. We give you the full price range for your system before anything begins, in writing, and that is the price. Cleaner air from the vents on out should not come with a surprise invoice at the end, and in Alpharetta where homes range from 1970s split-levels to brand-new brick and hardcoat builds, every system sizes differently. Your quote reflects your home, not a generic chart.
6. The Garrison Standard Warranty: One Full Year
Every Hollis job is covered by a written one-year guarantee. If anything we cleaned fails to hold up within that year, we come back and make it right at no charge. That’s not a promotional line; it’s the same standard every Hollis location in the Garrison Partners family works to. Roy Castellanos and the Alpharetta team stand behind it on every single system, from a small ranch in Duluth to a five-bedroom in Suwanee.
Our Promise to You
Here is what working with Hollis Air Duct Alpharetta looks like, every time. You schedule a time, and you get a window. We show up inside that window, and the price goes in writing before any work starts. The crew does the job by the book: real agitation, real collection, real negative air where it’s called for, not just a shop vac taped to a register. They put everything back the way they found it and leave the site clean. Then you get a written warranty that says the work is covered for a full year. If it fails in that time, we come back and make it right at no charge. That is the whole promise, and it’s the same one every Garrison company makes. No fine print, no bait-and-switch, no surprises. Just cleaner air, from the vents on out.
