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.
Fast, Reliable Air Duct Repair Across Marietta
Air duct repair in Marietta usually costs between $350 and $1,400 for the most common jobs, depending on whether the problem is a crushed flex-duct section, a disconnected joint, or failing original runs from the 1980s and 1990s. We’ve worked in enough East Cobb homes to know that what looks like a cleaning job often turns into a repair once a camera goes into the ductwork. Marcus Veale, who runs our repair division, will tell you the same thing: Marietta’s older housing stock hides problems that generic duct cleaners never check for. Call us at (980) 447-2498 and we’ll talk through what you’re seeing before we ever schedule a visit.
Why Linden Air Duct Cleaning Is Marietta’s Preferred Air Duct Repair Company
We’ve been serving homeowners since 2004 as part of the Threshold Group family, and our Marietta customers keep our phones busy for one reason: we find what others miss. The homes off Roswell Road, around Marietta Square, and throughout East Cobb’s 30062 and 30068 zip codes have duct systems that are 30 to 45 years old, with original flex runs that were never designed to last this long. Our Air Duct Repair team runs camera inspections on every job, not just when the homeowner complains. That’s how we catch disconnected joints and crushed elbows that have been silently wasting air conditioning for years.
The Threshold Standard applies to every tech we send into Marietta: background-checked, identity-verified, and photo-badged. You get the technician’s name and photo before the visit, and they show a photo ID badge at your door before stepping inside. We put the price in writing before any work begins, and every repair is backed by the 365-Day Done Right Promise. If the repair fails within 365 days, we come back at no charge. No fine print, no arguing.
Ductwork Installation in Marietta
Ductwork installation in Marietta becomes necessary when an existing run has failed beyond patching, or when a renovation added square footage that the original system can’t serve properly. The job typically runs $1,200 to $4,800 depending on the length of the run, the accessibility of the attic or crawlspace, and whether we’re replacing one branch or an entire trunk line. We give you one written price for the full system before any materials are ordered, and that price doesn’t change after we open the wall or ceiling.
What Installation Actually Involves
The work includes removing the old duct, sizing the replacement to match your air handler’s output, hanging the new run with proper support, and sealing every joint with mastic, not tape. In Marietta, we also account for the humid summers, which means sealing matters as much as the duct itself. A small air leak in July compounds into mold conditions by August.
When a Homeowner Needs It
If a camera inspection shows a run that’s collapsed, torn, or so loaded with debris that source removal can’t restore proper airflow, replacement is the honest answer. We won’t sell you a full-system install if a $400 repair solves it. But when the branch serving a finished basement or a 1990s bonus room has failed at the elbow, a new run is often cheaper than repeated attempts at patching.
HVAC Duct Installation in Marietta
HVAC duct installation in Marietta is the full-scope job, where the entire distribution network is replaced rather than a single branch. The cost generally runs $3,500 to $9,000 for the average Marietta home, with two-story East Cobb colonials on the higher end because of the long, multi-zone layout. We’ve installed full systems in 5,000-square-foot homes off Lower Roswell Road where the flex runs were original to the 1980s build and had never been touched. At that age, patching one section just moves the failure to the next weak point.
Full-System Replacement
This involves removing all supply and return ducts, sizing new runs to current HVAC codes, and installing rigid or flex duct according to the home’s layout. We use professional-grade equipment from Rotobrush and Nikro for the cleanup phase, and we’ll discuss air-quality products from Aprilaire and Guardsman if your system would benefit from additional filtration at the return.
The Real Marietta Difference
In East Cobb’s 30062 and 30068 zip codes, full-system replacement often reveals what individual repairs can’t: multiple failing sections, original trunk lines undersized for finished basements, and flex branches that were never properly hung. We quote the full system once, in writing, so you can plan the work without watching the invoice climb.
Trusted Brands We Service in Marietta
We work on and install duct systems from the major brands Marietta homeowners already have: Aprilaire filtration components, Abatement Technologies products for mold and particulate control, Guardsman air-quality solutions, and Rotobrush equipment for the cleaning and extraction side of the job. Our techs carry the common fittings, connectors, and sealants needed for most repairs, which means we can usually complete the job in one visit rather than leaving your system open while we order parts. That matters when it’s July and your upstairs bedrooms are already uncomfortable.
Common Air Duct Repair Problems We See in Marietta Homes
- Collapsed flex-duct elbows in 1990s bonus-room additions. The long, unsupported runs added during Cobb County’s build-out sag over time, crimping the curve until airflow drops to almost nothing. Homeowners report hot rooms for years before anyone checks the duct itself.
- Disconnected joints in original supply runs from the 1980s. Where flex duct meets a metal trunk or boot, the tape fails and the joint separates. Conditioned air dumps into the attic or crawlspace, and pollen-heavy outdoor air gets pulled into the system instead.
- Moisture-fed mold growth in return ducts far from the air handler. The humid subtropical summers in Marietta keep average July dewpoints around 70°F. When air-sealing fails, that moisture condensates inside the duct, and the pine and oak pollen that infiltrated in spring becomes a mold food source.
- Crushed trunk lines hidden behind finished basements. During the 1990s basement-finishing wave in East Cobb, many duct runs got enclosed behind drywall without proper clearances. A camera inspection through the return is often the first time anyone has seen the condition of those runs in decades.
Pricing for Air Duct Repair in Marietta, GA
A straightforward repair, like re-securing a disconnected joint or sealing a small tear, runs $350 to $600 in Marietta. Replacing a single crushed flex-duct branch costs $500 to $1,200 depending on the length and how much of it runs through finished space. A full HVAC duct installation in a 3,000 to 5,000-square-foot East Cobb home starts around $3,500 and goes up from there. What changes the price is access: attics with low clearance, crawlspaces with tight clearances, and runs buried behind finished drywall all take more time. We give you one written price for the complete job before any work starts. Call (980) 447-2498 and we’ll come out, inspect what’s actually wrong, and quote you honestly.

FAQs About Air Duct Repair in Marietta
In most cases we see, the cleaning didn’t address the actual problem. The long flex-duct runs in East Cobb’s 3,000 to 5,000-square-foot homes hide collapsed elbows and disconnected joints that cleaning alone can’t fix. Once we run a camera through the branch lines, we usually find a physical failure that needs repair before airflow will ever stabilize. Call (980) 447-2498 and ask for a camera inspection before paying for another cleaning.
We use video camera inspection through the return and supply openings, which lets us see the inside of runs that are otherwise inaccessible behind finished drywall. In the large colonials off Post Oak Tritt Road and Lower Roswell Road, we commonly find that flex branches added in the 1990s have collapsed at the elbows from years of sagging on undersized supports. The camera confirms it before we touch anything.
Repair usually means accessing the failed section, removing the damaged flex or duct board, and replacing it with properly supported, correctly sized material. We also seal every joint with mastic rather than tape, because Marietta’s humid summers find every small leak. The work typically takes one to two days depending on how many branches need attention and whether they run through finished areas.
Yes. NADCA, the National Air Duct Cleaners Association, sets the standards for source-removal cleaning and duct system repair, and we work to those specifications on every Marietta job. That means negative-pressure extraction, proper containment during cleaning, and mechanical agitation of the duct surfaces. It also means we don’t cut corners on sealing or support when we’re putting a system back together.
Nearly always, yes. We were called to a two-story brick colonial off Post Oak Tritt Road in East Cobb where the upstairs bonus room had never gotten proper airflow. Our tech ran a camera inspection down the 1990s-era flex branch and found the elbow crushed flat from years of sagging on undersized supports. After source removal and re-supporting the run, we reconnected and sealed the joint; the homeowner finally felt air in that room for the first time in years. If your bonus room has always been warmer than the rest of the house, call (980) 447-2498 for a camera inspection before you replace the HVAC system.
