Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

McDonough isn’t like the older intown Atlanta markets. This is one of the fastest-growing suburbs on the south side, and much of its housing boom sits in former cotton-field subdivisions built from the late 1990s through the 2010s. That means the air-duct work here is dominated by builder-grade flex-duct systems in 10-to-25-year-old homes hitting their first major cleaning, not the century-old plaster-and-galvanized retrofits you’d find closer to the city center. Add the red Georgia clay that surrounds every slab foundation here, and duct cleaning in McDonough becomes a dual fight: construction and renovation dust in rapidly infilling subdivisions, plus the powdery clay particulate that gets tracked into return-air systems and never really stops coming.
Why Hollis Air Duct Cleaning Is McDonough’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our track record predates most local competitors in the McDonough market. That matters because we’ve watched this city grow. We know the difference between a 2005 build in Kelleytown and a 2018 build off Midway Road near Ola, and we know what shortcuts the builders took in each phase.
Every Hollis job comes with a written price before we touch anything, backed by our 365-Day Done Right Promise. If the work fails within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround. Our technicians are background-checked and uniformed, and we follow The Garrison Code on every McDonough job: arrive inside the quoted window, price in writing, complete the work by the book, and leave the site clean.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday when your system is pumping dust into your kid’s bedroom.
Vent Cleaning in McDonough
Vent Cleaning in McDonough means pulling the supply and return registers, agitating the duct walls with rotary brushes or compressed-air whips, and extracting the debris under negative pressure with HEPA filtration. Most McDonough homeowners need this every 3 – 5 years, sooner if they’ve done recent renovation or if the home was built during the 2000s construction boom and never cleaned. A typical vent cleaning for a 2,000 – 3,000 square foot McDonough home runs $350 – $550. Call (361) 326-5060 for an exact quote.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms. In McDonough’s newer subdivisions, we regularly find these boots never sealed to the drywall at construction, so attic air, pest debris, and that fine red clay dust leak straight into your living space. We remove the registers, seal the gaps with mastic, and clean the runs properly.
Return Vent Cleaning
Return vents pull air back to the handler. They’re the intake point for everything floating in your McDonough home: pollen from the pine and oak stands, drywall dust from the neighbor’s renovation, clay grit from the dog and the kids. Returns clog faster than supplies and need equal attention.
Air Duct Repair in McDonough
Air Duct Repair in McDonough is almost always flex-duct work in unconditioned attics, and it’s rarely a full replacement. Crushed, sagging, or disconnected R-6 and R-8 flex runs are the norm in subdivisions built between 1995 and 2020. Typical repair costs run $200 – $500 per damaged run, with full system replacement only when the trunk itself has failed. We inspect with video first, show you what we found, and give you a written price before we cut anything.
Flex Duct Reconnection and Support
Sagging flex duct kills airflow and strains your HVAC system. In McDonough’s humid attic summers, unsupported flex also collects condensation that breeds biological growth. We rehang with proper strapping, replace damaged insulation, and seal every joint with mastic, not tape that dries and fails.
Boot Sealing and Air Leak Repair
Unsealed supply boots are an epidemic in McDonough’s builder-grade homes. We pull the register, clean the boot, and seal it to the drywall with fire-rated mastic as part of our Duct Sealing in McDonough service, restoring the pressure boundary your builder skipped. The difference in dust levels is immediate and measurable.
Trusted Brands We Service in McDonough
Our Air Duct Cleaning crews run professional-grade equipment, not hardware-store gear. We use Nikro negative-air machines and Rotobrush rotary brush systems for agitation and extraction, paired with HEPA filtration rated to capture particles down to 0.3 microns. For homeowners upgrading filtration after cleaning, we stock Honeywell and Aprilaire media cabinets and Abatement Technologies filtration products, with fast turnaround for McDonough customers who want better protection against the pollen and clay particulate this area throws at their systems. Every piece of equipment is explained in plain terms before we start, so you know what we’re running through your ducts and why.
Common Air Duct Cleaning Problems We See in McDonough Homes
- Builder-grade flex duct in unsealed supply boots pulls unfiltered attic air straight into bedrooms. This shortcut from staged construction in subdivisions like those off Highway 81 and Lake Spivey Road means drywall dust, pest debris, and hot attic air mix with your conditioned air. We seal the boots properly and source-remove the accumulated debris.
- Attic-run R-6/R-8 flex sweats in McDonough’s humid summers, growing biological growth and trapping pollen. Pine, oak, and agricultural pollen loads here are heavy, and mild winters give the system no seasonal downtime to clear. The result is a duct network that never really dries out.
- Red Georgia clay tracked onto slab foundations becomes powdery particulate that coats return-air systems. This clay defeats low-MERV filters and builds up in the return trunk, restricting airflow and recirculating grit through the home.
- Crushed and sagging flex runs from poor original installation reduce airflow to distant rooms. In McDonough’s long ranch and two-story plans, the master suite or back bedrooms often suffer while the living room freezes, all because a flex run kinked in the attic ten years ago.
Pricing for Air Duct Cleaning in McDonough, GA
Whole-house residential air duct cleaning in McDonough runs $350 – $650 for a typical 1,800 – 3,500 square foot home with one central system. Commercial duct cleaning starts around $800 and scales with system count and access difficulty. Dryer vent cleaning is typically $150 – $250 when booked with duct cleaning, or $200 – $300 standalone. What moves the price: number of supply and return vents, whether we need to repair or replace damaged flex runs, accessibility of the attic or crawl space, and contamination level. A home with unsealed boots and heavy construction debris takes longer than a maintained system on its routine cycle. We give one flat price per system, agreed in writing before we start. No per-vent add-ons, no surprises at the door. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in McDonough
Yes, and probably more than a 1960s intown home does. McDonough’s 2010s subdivisions were built fast, in staged phases, and builder-grade flex duct often collects drywall dust, sawdust, and red-clay grit that was never cleaned out at handover. We regularly find supply boots unsealed to the drywall in homes less than ten years old, pumping attic air into bedrooms. A 2016 build in McDonough can have worse indoor air quality than a fifty-year-old house with hard metal duct that was properly sealed. Call (361) 326-5060 for an inspection and exact quote.
McDonough sits on thick red clay that surrounds every slab foundation and gets tracked inside on shoes, paws, and HVAC return airflow. That clay dries to a fine, abrasive powder that coats return ducts, clogs low-MERV filters, and recirculates through the home. It’s a particulate load you don’t see in sandy-soil markets, and it’s why McDonough homes often need more frequent return-side attention. Call (361) 326-5060 to schedule a cleaning that addresses clay buildup specifically.
We can repair most crushed, sagging, or disconnected flex duct without full replacement. Our video inspection shows you the damage first. Typical repairs run $200 – $500 per run, with reconnection, proper support strapping, and mastic sealing. Full replacement is only needed when the trunk line itself has failed or when multiple runs are damaged beyond patching. We give a written price for either scenario before we start. Call (361) 326-5060 to book an inspection.
Dryer vent cleaning is a separate service, though we discount it when booked with duct cleaning. A typical McDonough dryer vent cleaning runs $150 – $250 with duct cleaning, or $200 – $300 standalone. We recommend doing both together because the same particulate load affecting your ducts also clogs your dryer vent, creating a fire hazard and extending dry times. Call (361) 326-5060 to bundle both services.
Yes. Our negative-air method with Nikro equipment maintains continuous suction during agitation, and our HEPA filtration captures particles down to 0.3 microns.
