Why Hollis Air Duct Alpharetta Is Roswell’s Preferred Air Duct Cleaning Company
We’re not a national chain. We’re part of the Garrison Partners family, independently owned and operated under The Garrison Standard, which means our Roswell customers deal with one accountable local crew, not a rotating cast of subcontractors. The standard is simple and written: arrive inside the quoted window, put the price in writing before work starts, complete the job by the book, and leave the site clean. That’s the whole deal.
Roy Castellanos leads our team, and every technician who walks into a Roswell home is background-checked and uniformed. You’ll know who’s coming before they ring the bell. Our phones are answered by a live person 24 hours a day, 7 days a week, so if you call at 8 PM on a Tuesday with a question about your ducts, you’ll talk to a human being, not a voicemail tree. When we send a crew to Roswell, they know the roads, the neighborhoods, and the specific duct problems this city’s housing stock throws at homeowners. That local knowledge is what keeps our customers from paying for a second cleaning six months after the first.
Styles & brands we work with
Air Duct Repair in Roswell
Air duct repair in Roswell often comes down to fixing what decades of humidity, sagging flex duct, and loose return boots have damaged in 1970s-90s era homes. When we clean ducts in neighborhoods like Martin’s Landing or Willow Springs, we routinely find disconnected or collapsed sections of flex duct in crawlspaces, gaps where return boots meet the drywall, and crushed duct runs under houses. We repair all of it as part of the job, so the cleaned system actually stays clean.
Duct repair work in Roswell typically adds $150 – $400 to a cleaning job, depending on what we find. That covers resealing return boots with mastic, reattaching disconnected flex runs, and replacing crushed sections where repair isn’t possible. If we spot damage during the cleaning, you’ll get a written price before we touch the repair. Nothing changes at the door.
Return Boot Sealing
In many Roswell split-levels and ranches, returns are cut into hallway walls with poor sealing around the boot. When the system runs, it pulls attic or crawlspace air through those gaps, and that air carries insulation fibers and pine pollen right back into the ducts. Sealing the boots with mastic is the step that separates a real fix from a temporary cleaning.
Crawlspace Flex Duct Repair
Sagging flex duct in a Roswell crawlspace acts like a gutter for debris. Low spots fill with pollen, leaf litter, and dust, and every cooling cycle drags that material through the house. Straightening or replacing those sagged runs is often the single most effective repair we perform in older Roswell homes.
Ductwork Cleaning in Roswell
Ductwork cleaning in Roswell is not a surface-level vacuum job. We use the negative-air method, which means a HEPA-filtered vacuum pulls the system under continuous suction while a rotary brush system from Rotobrush agitates debris loose from the duct walls. Debris is removed at the source, not just stirred up and spread around your house. That matters in a climate where pollen season runs for months and humidity keeps particles sticky.
A full ductwork cleaning for a typical Roswell home runs $350 – $650 depending on square footage, number of systems, and accessibility of the ductwork. Homes with crawlspace ducting or multiple returns take longer and run slightly higher. You’ll see the price in writing before the first tool comes off the van.
Supply and Return Duct Cleaning
We clean both sides of the system. Supply ducts in Roswell homes tend to collect dust and debris from the air handler, while return ducts pull in whatever floats through your living space, including pollen, pet dander, and dust from old carpet. Skipping the return side means you’ve cleaned half the loop.
Full System Cleaning with Video Inspection
Every Roswell job includes a video inspection before and after. You’ll see the inside of your ducts with your own eyes, including the before-and-after footage. No guessing, no “trust us.” If a section of duct can’t be cleaned because it’s collapsed or too deteriorated, you’ll see that on camera too, and we’ll explain what the repair would involve.
Trusted Brands We Service in Roswell
We service and clean duct systems tied to every major HVAC brand found in Roswell homes, from older Trane and Carrier units in 1980s ranches off Holcomb Bridge Road to newer Lennox and Goodman systems in Craftsman-style infill builds. Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell and Aprilaire. We carry common filter sizes on the van, and we can source Roswell-specific parts from local supply houses quickly. If your system needs a new Aprilaire media cabinet or a Honeywell filter upgrade, we’ll quote it at the time of service, in writing.

AfterCommon Air Duct Cleaning Problems We See in Roswell Homes
- Pine pollen coating on ducts and coils. Roswell’s loblolly pines and oaks dump enormous amounts of pollen every spring. It coats evaporator coils, lines duct walls, and recirculates through returns for months after the pollen peaks. A proper cleaning plus sealing return boots is the only fix that lasts all season.
- Sagging flex duct in crawlspaces. Homes built between 1970 and 1990 often have flex duct running through humid crawlspaces. Over decades, that duct sags, catches water and debris, and becomes a reservoir for contaminants. We see this on nearly every older Roswell home we service.
- Undersized hallway returns. Many split-levels and ranches in Roswell were built with single hallway returns and undersized grilles. That restricts airflow and forces the system to pull air through whatever gaps exist, including unsealed wall cavities and attic spaces. Cleaning helps, but the system will re-contaminate unless the returns are properly sealed and, in some cases, upsized.
- Humidity-driven microbial growth. Roswell’s summer thunderstorms push indoor humidity high, especially in homes with crawlspace ductwork. When moisture sits in ducts or around the air handler, microbial growth follows. We address moisture sources during cleaning so the problem doesn’t return with the next rainstorm.

FAQs About Air Duct Cleaning in Roswell
Every 3 – 5 years for most Roswell homes, and every 2 – 3 years if you live near dense pine stands in neighborhoods like Martin’s Landing or off Holcomb Bridge Road. Roswell’s pollen season is longer and heavier than in many neighboring cities, and pollen that gets past the filter will coat duct surfaces quickly. If you’re seeing yellow-green dust on furniture within days of wiping it down, your ducts are overdue. Call (762) 769-7145 and we’ll tell you what you’re actually dealing with, no obligation.
Yes. Crawlspace ductwork common in 1970s-90s Roswell homes needs rotary brush agitation and negative-air extraction with HEPA filtration to remove debris that has settled in sagging runs. A standard push-vacuum or blower-only approach won’t pull debris out of low spots in flex duct. Our Nikro negative-air machines and Rotobrush agitation tools are built for exactly this kind of system. We’ll also inspect the crawlspace for moisture and sagging while we’re down there.
Duct cleaning alone will reduce it, but it won’t solve it permanently unless return boots are sealed and attic insulation is addressed. In Martin’s Landing and Willow Springs, we regularly find return boots that aren’t sealed where they meet the drywall, pulling attic air and insulation particles into the duct system alongside pine pollen. Cleaning removes what’s already there. Sealing the boots stops the cycle. We do both, and you’ll see the difference in the before-and-after video from our inspection camera. For an exact quote, call (762) 769-7145.
We coordinate with your HOA or property management before scheduling, and our crew is used to working within Roswell condo communities with restricted parking and long hose runs. Shared dryer stacks require extra planning to clean the full run properly, and we’ll map the vent path before starting. Lint left in a shared stack is a fire hazard, so we don’t cut corners on access. If the building uses a shared exhaust, we’ll tell you exactly what’s cleanable and what the HOA may need to address separately.
MERV 11 – 13 for most Roswell homes, placed in a properly sealed filter cabinet. Anything higher than MERV 13 will restrict airflow in older systems, which many Roswell ranches and split-levels have. Our crew cleaned a 1980s split-level off Holcomb Bridge Road where original flex duct in the crawlspace had sagged and collected years of pine pollen and leaf litter. We used Rotobrush agitation under negative pressure with HEPA filtration, and after sealing the return boots, the yellow-green dust stopped reappearing. The right filter, correctly fitted, completes that job. Call (762) 769-7145 and we’ll help you pick the right one for your system.
