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.

We know Duluth’s housing stock well. Most of our repair calls come from the big two-story subdivisions built between 1992 and 2005: Sugarloaf, Berkeley Commons, Cardinal Lake, and the neighborhoods off Peachtree Industrial Boulevard and Pleasant Hill Road. These homes share a common problem, which is long flexible duct runs that sag over time and trap condensation in Georgia’s humid summers. That’s not a generic issue. It’s the specific reality of duct systems in Duluth, and we repair them every week.

Our customers around Gwinnett County tell us the same thing: they’d rather pay a fair price once and know the work is done right than gamble on a low bid that turns into an upsell.

HVAC Duct Installation in Duluth
HVAC Duct Installation in Duluth usually means one of two jobs: running new flexible or rigid duct from the air handler to rooms that never had proper airflow, or replacing sections of duct that have collapsed, separated, or been chewed through. In Duluth’s larger two-story homes, a single air handler can feed 14 or more supply runs, and a bad installation on any one of them throttles the whole zone. Expect to pay $1,200 – $3,800 for a full new duct system installation on one HVAC unit in a Duluth home, with partial runs replacing sagging or collapsed sections typically running $400 – $1,100 depending on length and accessibility.
Proper Support and Slope
The most common installation mistake we see in Duluth’s 1990s subdivisions is improper support: flex duct laid across attic trusses with minimal strapping, sagging at 8 to 12 feet between hangers. We rebuild those runs with the correct support intervals and the proper slope so condensation drains the right direction. In a two-story home with three systems, one poorly hung run can make an entire upstairs zone feel like a sauna in August.
Documented Installation Work
Since you can’t walk into your attic and check every run by eye, we photo and video each installation before we close up. You get a system-by-system report showing what was removed, what was installed, and how it’s supported. That’s the standard in Duluth, and we’re not going to give you less.
Air Duct Replacement in Duluth
Air Duct Replacement in Duluth is the path when cleaning won’t solve the problem because the duct itself is done: the inner liner is deteriorating, the insulation is waterlogged, or the flex duct has collapsed at mid-span. Homes in Duluth built during the 1992 – 2005 boom are hitting that age together. The builder-grade flexible duct and duct board installed in those years is now 20 to 30 years old, and in Georgia Piedmont humidity, it doesn’t age quietly. Full air duct replacement for a single HVAC system in Duluth runs $1,400 – $4,200 depending on run count, access, and whether we’re also replacing the duct board plenum.
Replacing Deteriorating Duct Board
Duct board with a deteriorating interior liner holds moisture and feeds mildew that cleaning alone can’t fix. In Duluth’s large subdivision homes, we frequently find entire plenums and return drops built from duct board that has turned soft and spongy. Replacement is the honest fix, and it costs less than letting the problem spread through three connected systems.
A System-By-System Approach
When a Duluth home runs three separate air handlers, replacement should be priced per system, not as one blanket number. A healthy system needs only the failed run replaced. A compromised system may need its entire supply and return network rebuilt. We show you the difference on camera, and we put each system’s scope and price in writing before we start.
Trusted Brands We Service in Duluth
We work with professional-grade equipment including Rotobrush and Nikro agitation and negative-pressure extraction systems, and we use air-quality products from Honeywell, Aprilaire, and Abatement Technologies. For Duluth homeowners, that means we don’t have to wait on a parts depot in Atlanta for common fittings, flex duct, and duct board replacements. We stock what Duluth’s housing stock actually needs: replacement flexible duct in common diameters, collars, support strapping, mastic sealant, and plenum materials. Service brands like TRANE, Carrier, Lennox, Goodman, and Rheem are all within our regular scope, and we match duct repairs to the existing system rather than forcing an upgrade you don’t need.
Common Air Duct Repair Problems We See in Duluth Homes
- Sagging flex duct at mid-span. In Duluth’s 1990s and early 2000s two-story homes, long flex runs were installed with too few supports, and after 20 years they dip at the middle. Those low pockets collect condensation, dust, and eventually microbial growth. They’re the single most common repair we make in this city.
- Deteriorated duct board liners. Duct board was the standard for plenums and return drops during Duluth’s building boom. In Georgia Piedmont humidity, the interior liner breaks down, holds moisture, and forms the exact conditions mildew needs. If the liner is soft or stained, replacement is the only honest fix.
- Collapsed runs behind second-floor bonus rooms. Bonus rooms over garages are notorious in Duluth because the duct runs there are long, exposed to attic heat, and often not supported properly from day one. A collapsed run there sends airflow nowhere and stresses the whole system.
- Disconnected or leaky joints at the plenum. Production builders in the 1990s weren’t always careful with tape and mastic at the air handler connection. Twenty years of vibration and heat cycles loosen those joints, dumping conditioned air into the attic and pulling humid Georgia summer air into the return side.
Pricing for Air Duct Repair in Duluth, GA
Here’s what you should expect before you call. A simple repair like reconnecting a separated joint or sealing a leaky plenum collar in Duluth runs $180 – $350. Replacing a sagging flex run costs $350 – $650 for most accessible attic runs, or $500 – $900 if we’re rebuilding a long run with new supports and mastic sealing. Full air duct replacement for one HVAC system in a Duluth home sits at $1,400 – $4,200. The honest variables are run length, access, and whether one system or three need work. We give you a written price per system before anything starts, and we don’t add a per-vent charge at the end. Call (980) 447-2498 for a free estimate.

FAQs About Air Duct Repair in Duluth
Because your Duluth home likely runs multiple HVAC systems. The 3,000 to 5,000+ square foot houses built in Duluth between 1992 and 2005 commonly have three separate air handlers, each feeding its own supply and return network. A repair on one system doesn’t touch the other two, and pricing one flat number for three systems either overcharges you for the healthy ones or underfunds the one that’s actually failing. We scope and price each system separately, and we show you what we found in each one. Call (980) 447-2498 for a free per-system estimate on your Duluth home.
We use camera inspection to look inside the duct from the register or a small access point, and we combine that with airflow testing at each vent. In a Duluth bonus room, a collapsed flex run usually shows up as weak airflow, a musky smell in summer, and a register that feels warm compared to the others. The camera shows us the sag point and the depth of the collapse so we don’t have to guess. Call (980) 447-2498 and we’ll bring the camera in.
You should get photo and video of the failed duct before repair, the new duct or seal after repair, and a written sentence or two per system saying what was replaced and why. That’s what we provide on every job in Duluth. It’s the only way to prove the work happened, and it’s the foundation of the 365-Day Done Right Promise: if a covered repair fails, the documentation shows what we did so we can return and fix it at no charge.
Duluth sits in the Georgia Piedmont, where summer humidity pushes indoor relative humidity to the top of the scale in under-conditioned duct systems. Combine that with the long flex runs and duct board plenums common in Duluth’s 1990s-era subdivisions, and you get low airflow zones that stay damp for weeks. Mildew doesn’t need much more than damp fiberglass liner and warm attic air, which is why we see more mold and mildew inside duct board in Duluth than in many other metro Atlanta communities. Replacement to NADCA standards removes the source instead of wiping the surface.
Yes, and it’s usually the fastest energy win available in a Duluth home. A disconnected or sagging supply run dumps conditioned air into the attic while your system runs longer to compensate. Sealing one major plenum leak or replacing a collapsed run can cut the runtime on the connected system measurably. In a three-system home, repairing the failing system often raises comfort in its zone enough that you stop overriding the thermostat upstairs. The savings show up on the next Gwinnett County summer bill, and the fix is a one-time repair, not a new HVAC unit. Call (980) 447-2498 to schedule a diagnosis.
If your Duluth home’s ducts are 20 years old or more, or if you’re getting weak airflow and a musty smell every summer, we’re the duct repair contractor who shows documentation and a written price before the work starts. Call (980) 447-2498 for a free estimate.
