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.

Air duct repair in Kennesaw typically runs $250 – $700 for a targeted fix like resealing a detached flex run or replacing a crushed section, while a full replacement of the accessible attic ductwork in a 2,000 – 2,800 square foot home lands between $1,800 and $4,200. We’re in Kennesaw neighborhoods like Legacy Park, Ridenour, and the subdivisions off Stilesboro Road every week, so we know what your attic looks like before we climb the ladder. If your registers are pushing dust, some rooms never reach temperature, or your air handler runs constantly, call (980) 447-2498 and we’ll send a verified technician to diagnose the problem.
Why Linden Air Duct Cleaning Is Kennesaw’s Preferred Air Duct Repair Company
Kennesaw homeowners keep our number because we do something most duct companies in Cobb County don’t: we tell you exactly who is coming to your door before the visit. Every technician is background-checked, identity-verified, and arrives in a clean, marked uniform. You get the tech’s name and photo sent to you ahead of time, and they show you a photo ID badge at the door. That’s the Threshold Standard, and it matters when you’re home alone or your kids are napping in the next room.
We’ve been part of the Threshold Group family since 2004, serving homeowners across metro Atlanta, and our crews work Kennesaw daily. Marcus Veale leads our operation, and he built our approach around one thing: a written price before any work starts, every single time. No surprise invoices when the job is done. Every repair also carries a written guarantee, and if a covered repair fails, we come back at no charge. That’s the 365-Day Done Right Promise, and it’s in writing on every job we do in Kennesaw.
Local reviews from Kennesaw customers consistently mention two things: the tech explained what they found in the attic before touching anything, and the final invoice matched the quote. For an industry with a bait-and-switch reputation, that’s the highest compliment we can get.
HVAC Duct Installation in Kennesaw
HVAC Duct Installation in Kennesaw most often means replacing the builder-grade flex runs that were draped through attics when subdivisions like Legacy Park, Summerhour, and the Barrett Parkway corridor went up in the 1990s and early 2000s. For a typical 2,000 square foot home, installing new R-6 flex duct in the accessible attic zones runs $1,900 – $3,600 depending on how many runs are accessible and whether the air handler plenum needs refitting.
Signs Your Existing Runs Are Failing
If supply registers in upstairs rooms blow weak while the downstairs feels fine, the inner liner of a flex run has likely sagged or kinked where it crosses attic trusses. We’ve also seen inner liners separate from the outer jacket entirely, so airflow dumps into the attic instead of the room.
What Installation Actually Covers
We replace the runs, yes, but we also strap them properly this time with saddles or stretched support, not zip ties pulled tight enough to choke the flex. Every new run gets sealed with mastic at both ends, not duct tape, because tape adhesives bake off in a Kennesaw attic that hits 130°F by July.
Air Duct Replacement in Kennesaw
Air Duct Replacement in Kennesaw is the option when the existing system is too degraded for a patch, and the owner wants the whole accessible portion of the attic ductwork redone to fixed specs. For most Kennesaw homes, a full accessible replacement runs $2,200 – $4,800, with the higher end applying to two-story plans where the return drop is long or the air handler sits in a tight closet.
Choosing Between Repair and Replacement
If only one run is crushed or disconnected, a targeted repair makes more sense and usually costs under $400. But when multiple runs show tape failure, liner separation, or debris packed into the low points, replacing the accessible system in one job costs less than repairing it piecemeal over three service calls.
The Kennesaw Builder-Shortcut Problem
Homes built quickly during Cobb County’s growth years often have flex duct draped loosely across attic trusses rather than properly supported. We see this pattern so often in Kennesaw that we check for it before pulling any access panel. The fix is straightforward: remove the failed runs, correct the support points, and install new duct that won’t sag.
Trusted Brands We Service in Kennesaw
We service and install ductwork, blowers, and air-quality components from brands Kennesaw homeowners already trust, including Honeywell and Aprilaire for filtration and humidity control, plus Nikro and Rotobrush for the cleaning and agitation equipment we run. Because we work these brands daily, we keep common fittings, collars, and sealants stocked, so a repair on a Honeywell bypass system or an Aprilaire cabinet doesn’t stall waiting on a parts truck from Atlanta. We also specify Abatement Technologies filtration where a home needs serious particulate capture, which happens more often in Kennesaw than people expect given our spring pollen load. Call (980) 447-2498 and tell us what system you’re running; we’ll tell you straight whether the repair is worth doing.
Common Air Duct Repair Problems We See in Kennesaw Homes
- Detached flex runs at the boot. The builder’s tape fails at the register boot, air spills into the attic, and the room never heats or cools. We refit the boot, seal it with mastic, and test the airflow before we leave.
- Sagging liner trapping debris at low points. In the 1990s subdivisions off the Barrett Parkway corridor, crews routinely find flex duct draped loosely over attic trusses. The inner liner sags, debris pools in the dip, and the run acts like a filter you never asked for.
- Peeled tape joints pulling attic air. Duct tape adhesives fail after a few summers in a Kennesaw attic that routinely exceeds 130°F. When the joint opens, your system pulls insulation fibers, dust, and hot attic air straight into the supply side.
- Drywall dust and framing debris from handover. Builders leave construction debris inside new duct runs. In newer Kennesaw homes, that dust circulates through the air handler, blower motor, and every register for years unless someone actually cleans it out.

A targeted duct repair in Kennesaw, like resealing one detached run or replacing a crushed section, typically runs $250 – $700. Replacing all the accessible flex duct in a two-story 1990s subdivision home usually lands between $2,200 and $4,800, depending on how many runs are accessible from the attic and whether the plenum at the air handler needs refitting.

FAQs About Air Duct Repair in Kennesaw
Because builders don’t clean ducts before handover. Drywall joint compound dust, framing sawdust, and scraps of insulation sit inside the flex runs from day one, and your air handler blows that through the house until someone removes it. In newer Kennesaw subdivisions, we’ve pulled pounds of construction debris from ducts in homes less than three years old. Call (980) 447-2498 and we’ll inspect yours.
You’ll see a register that barely blows, a room that won’t hold temperature, or dust appearing on furniture right below an upstairs vent. In the 1990s-era subdivisions off the Barrett Parkway corridor, sagging flex is so common that we check the attic trusses on every diagnostic visit before we touch anything else.
We pull the access panel, inspect the run with a camera, then either re-support the sagging section with proper saddles or replace the damaged run entirely. The fix includes sealing both ends with mastic and testing airflow at the register before we call the job done. You get a written price before we start, and the repair carries a written 365-day guarantee.
Yes. Cobb County attics routinely exceed 130°F in summer, and that heat bakes the adhesive on duct tape until joints peel open. Once a joint opens, the system pulls hot attic air, insulation fibers, and dust directly into your supply side. It’s one of the most common failure modes we fix in Kennesaw.
Often, yes. If the register blows weak air but the system runs constantly, that points to a duct problem, not a cleaning problem. If the register blows strong air but dust keeps appearing on surfaces, it’s usually debris inside the runs. Either way, call (980) 447-2498 and we’ll diagnose it properly, with the price in writing before any work begins.
If you live in Kennesaw and your ducts haven’t been looked at since the house was built, or you’re seeing dust at the registers, weak airflow, or rooms that won’t hold temperature, call Linden Air Duct Cleaning at (980) 447-2498. We’ll send a verified technician to your door with a name, a face, and a written price before any work starts.
