AfterFast, Reliable Air Duct Cleaning Across Lilburn
Air duct cleaning in Lilburn, GA typically runs $350 – $650 for a full residential system and $800 – $2,400 for commercial work, with most jobs scheduled within a few days and completed in a single visit. Hollis Air Duct Cleaning dispatches crews to Lilburn from our Atlanta coordination office, and we’ve built our local reputation on showing up inside the window we quoted, pricing in writing before we touch anything, and leaving the site clean.
We know Lilburn’s housing stock. The ranches off Rockbridge Road, the split-levels near Killian Hill, the two-story traditional homes around Lawrenceville Highway – most were built between 1965 and 1995 with original galvanized steel supply trunks, undersized returns, and fiberglass duct board that doesn’t age gracefully. Our technicians carry Air Duct Cleaning equipment built for that reality: Rotobrush rotary systems and Nikro negative-air machines with HEPA filtration, not hardware-store vacuums with a brush taped to the hose. When you call (361) 326-5060, a live person answers, 24 hours a day. No voicemail loops. No callback queues.

Residential Air Duct Cleaning in Lilburn
Residential Air Duct Cleaning in Lilburn means source removal from every accessible supply and return duct, plus the main trunk lines, using negative-air extraction and mechanical agitation – not just a vacuum wand waved near the vent grille. Most Lilburn homes we service are 1,500 – 2,800 square foot ranches or split-levels built in the 1970s and 80s, so a typical residential job runs $350 – $650 depending on system size, duct material, and how much Duct Sealing in Lilburn the attic joints need.
We don’t just clean. We inspect with video. We find the crushed flex runs and disconnected joints that are pulling attic air into your living space. Then we fix them.
What We Find in Lilburn Attics
Original galvanized steel trunks corrode at the seams. Fiberglass duct board degrades and sheds fibers. Later HVAC replacements often sit air handlers on top of existing flex runs, crushing them flat. On a ranch off Rockbridge Road near the Lilburn city limits, our tech ran a camera inspection down the main return and found a run crushed flat where a later HVAC replacement had set the air handler on top of it, plus three separated joints in the attic duct board. We pulled the system under negative pressure, did source removal on the supply and return ducts with agitation tools with HEPA filtration at the exhaust, then rebuilt and sealed the failed connections and replaced the collapsed flex before it could keep feeding pine pollen and insulation fibers into the registers.
Supply Duct Cleaning and Return Duct Cleaning
Supply ducts push conditioned air to your rooms. Return ducts pull air back to the air handler. In Lilburn’s older homes, returns are often undersized and leaky, which means they’re pulling unfiltered attic air – red clay dust, insulation fibers, pollen – straight through gaps in the duct board. We clean both sides of the system and seal what we find. That’s the difference between a job that lasts and one that doesn’t.
Commercial Air Duct Cleaning in Lilburn
Commercial Air Duct Cleaning in Lilburn covers office buildings, retail spaces, medical clinics, and light industrial facilities along Lawrenceville Highway, Five Forks Trickum Road, and the commercial corridors near US-78. Commercial systems are larger, with more complex zoning and often rooftop units that see heavier runtime through Lilburn’s long, humid summers. Typical commercial jobs run $800 – $2,400 depending on square footage, system count, and access difficulty.
We work around your hours. Early mornings, weekends, phased shutdowns – we coordinate with your facilities manager and stick to the schedule we agreed.
Full System Cleaning for Commercial Clients
Our commercial crews use Nikro negative-air machines and Rotobrush agitation systems sized for larger ductwork. We clean supply and return trunks, branch lines, diffusers, and the air handler cabinet. If we find degraded flex connections or failed duct board in a Lilburn commercial ceiling plenum, we document it with photos and give you a written repair scope before we proceed.
Video Inspection and Documentation
Commercial clients need records. We provide before-and-after video of the duct interior, plus written condition reports. Property managers in Lilburn use these for lease compliance, insurance documentation, and maintenance planning. The video doesn’t lie. You’ll see exactly what was in your ducts and exactly what we removed.
Trusted Brands We Service in Lilburn
Our equipment comes from manufacturers who build for the trade, not the retail shelf. We run Rotobrush rotary brush systems for mechanical agitation inside ductwork, Nikro negative-air machines for controlled extraction with HEPA filtration, and we specify filtration and sealing products from Abatement Technologies and Guardsman when a Lilburn system needs component replacement or upgrade. These are the same tools commercial crews use in hospitals and schools. We don’t apologize for the cost of professional-grade equipment because we don’t have to apologize for the results. If your Lilburn home needs a media filter upgrade after we clean and seal the ductwork, we’ll size it to your system and your air handler’s capacity, not sell you whatever’s in the van.
Common Air Duct Cleaning Problems We See in Lilburn Homes
- “Black dust” blowing from vents every spring. It’s not mold. In most Lilburn homes, it’s pine pollen from the mature canopy combined with attic insulation fibers pulled through leaky duct joints. The ducts aren’t just dirty – they’re open to the attic. Cleaning without sealing just gives you a few months of relief before it starts again.
- Crushed flex runs under replaced air handlers. When HVAC contractors swap equipment in 1970s Lilburn ranches, they sometimes set the new air handler on top of existing flex duct. The run goes flat. Airflow drops. The system works harder. Your power bill climbs. We find these with camera inspection and replace them properly.
- Degraded fiberglass duct board shedding fibers. Original duct board in Lilburn split-levels gets brittle after 30 – 40 years. Aggressive high-pressure brushing releases fibers into the airstream instead of removing them. We use controlled agitation and negative-air extraction to avoid that.
- Undersized returns pulling unfiltered attic air. Many Lilburn homes were built with return paths too small for modern HVAC loads. The system starves for air and pulls through every gap in the attic ductwork – red clay dust, pollen, insulation. We identify this during inspection and recommend sealing or return path upgrades.

FAQs About Air Duct Cleaning in Lilburn
It’s usually pine pollen combined with attic insulation fibers pulled through leaky or disconnected duct joints, not mold or “dirty ducts” in the conventional sense. Lilburn’s mature pine and hardwood canopy dumps heavy pollen each spring, and older homes with original duct board or separated attic joints draw that plus fiberglass into the airflow. We find the leaks, seal them, and remove the accumulated material so it stops recurring. Call (361) 326-5060 and we’ll show you on camera exactly where it’s coming in.
Yes, with the right equipment and technique. Galvanized steel trunks in Lilburn’s 1965 – 1995 homes are durable but can corrode at seams or develop internal rust scale. We use controlled rotary brush agitation – not high-pressure air whips – and extract under negative pressure so dislodged debris exits through our vacuum, not your vents. If we find significant corrosion or seam separation, we document it and discuss repair options before proceeding. Call (361) 326-5060 for an inspection.
Often yes, because Lilburn’s humid subtropical climate creates condensation in attic ductwork during our long, hot summers. Where there’s moisture plus organic debris, there’s microbial growth risk. We evaluate this during inspection – musty odors, visible growth, or chronically damp flex runs are the indicators. When indicated, we apply an EPA-registered antimicrobial treatment after source removal and drying, not as a substitute for cleaning. It’s an add-on we quote separately, in writing, if your system needs it. Call (361) 326-5060 and we’ll assess your specific conditions.
We rebuild the connection with proper mechanical fasteners and seal it with mastic or foil tape rated for ductwork – not duct tape, which fails in attic heat. If the original material is degraded fiberglass duct board, we may replace that section with flex duct or sheet metal depending on code and access. The goal is a sealed, continuous air path so your system moves conditioned air, not attic air. Every repair is covered by our 365-Day Done Right Promise. Call (361) 326-5060 for a free inspection and written scope.
Every 5 – 7 years for a well-sealed system, but every 3 – 5 years for Lilburn’s older homes with original ductwork that has likely developed leaks. The combination of heavy spring pollen, red clay dust, and decades of accumulation in galvanized trunks means these systems benefit from more frequent inspection and cleaning. If you’re seeing dust accumulation on registers, noticing musty odors, or your filters clog within weeks of replacement, it’s time. Call (361) 326-5060 for a free estimate – we’ll inspect first and tell you honestly whether you need service now or can wait.
