Trusted Air Duct Repair for Marietta Homeowners
When a duct seam splits in a Marietta attic, it doesn’t announce itself with a bang. It shows up as a bedroom that never cools in July, a power bill that climbs $40 in a month, and dust settling back on furniture two days after you clean. That’s the moment you need Air Duct Repair - Marietta from a company that tells you exactly who’s coming to your door and exactly what the fix will cost before the van ever leaves the shop. Linden Air Duct Marietta has served homeowners since 2004 under the Threshold Group family, and every repair job is covered by a written 365-Day Done Right Promise. Our techs are background-checked, identity-verified, and you’ll see their name and photo before the visit. Call (912) 405-8840 to talk to a live person about what’s going on with your ducts.
HVAC Duct Installation
HVAC Duct Installation is the process of running new supply and return duct lines through unconditioned space – typically an attic, crawl space, or basement – so air moves from your furnace or heat pump to every register in the house. It’s not a patch job. Full installation happens when a home is built, when an addition goes up, or when the existing duct system is too damaged to salvage. In Marietta, where summer humidity sits heavy in attics and temperatures above the insulation regularly cross 130°F, installation standards matter more than most people realize. A poorly hung flex duct sags, collects condensation, and loses 20% or more of your conditioned air before it reaches a single vent. Linden Air Duct Marietta handles both full-system installation and section replacements, with a written price agreed before any work starts. Whole-home duct installation in Cobb County typically runs between $3,800 and $9,500 depending on square footage, the number of runs, and how difficult the attic or crawl space is to navigate. The quote is flat: one price per system, not a teaser that becomes something else when the crew arrives.
New Construction and Additions
When a Marietta homeowner adds a second story or finishes a basement, the existing duct design rarely keeps up. We size runs using ACCA Manual D calculations so the new space actually receives the airflow the system was designed to deliver. The work is done alongside your general contractor, with the same written-price guarantee we give on every project.
Repair vs. Full Install Decisions
Sometimes the honest answer is that installing new ductwork costs less over three years than patching the old system repeatedly. When a home has galvanized ducts from the 1970s with rusted bottoms or flex duct that’s collapsed in multiple places, a section-by-section repair approach just extends the problem. We walk through the numbers with you and let you decide with a full written quote in hand.
Styles & brands we work with
Air Duct Replacement
Air Duct Replacement is the removal and replacement of specific sections of ductwork that have failed – not the entire system, but the portion that’s leaking, crushed, mold-contaminated, or fallen apart at the joints. In Marietta, we see this most often in two places: attic flex duct that’s been walked on by cable installers or pest-control techs, and basement trunks that have rusted through from years of Georgia humidity. The decision to replace rather than patch comes down to the material’s condition. If the inner liner of a flex run is torn, sealing the outside does nothing. If a metal trunk has rusted thin in multiple spots, another roll of foil tape is just postponing the inevitable. Linden Air Duct Marietta replaces failed sections with properly insulated, correctly hung material sized to the original design. A typical single-run replacement in a Marietta split-level runs $1,200 to $2,600, with the total depending on how much of the section is accessible without opening drywall.
Attic Flex Duct Failures
Flex duct in a Cobb County attic has a hard life. Rodents nest in it, heat degrades the outer jacket, and the plastic inner liner tears at connection points as the duct settles. When we replace flex runs in Marietta attics as part of our Air Duct Repair in Smyrna service area, we use strapping every four feet and keep bends to a minimum – a detail that adds years to the life of the new run.
Mold and Contamination Replacement
When a duct section shows active mold growth or has been contaminated by a pest infestation, cleaning is not the right first step. The affected section should come out and be replaced, then the root moisture problem addressed. We use Abatement Technologies equipment for containment during this work, so spores don’t get pushed into the living space while the bad section is removed.
Ductwork Repair
Ductwork Repair is the methodical work of finding and fixing leaks, separations, and weak points in an existing duct system so it holds pressure and delivers the airflow it was designed to carry. It is the most common duct service we perform in Marietta, and unlike Kennesaw Air Duct Repair competitors, we make sure homeowners understand exactly what’s being fixed. A separated joint at the plenum can leak 15% of the air your system moves. A single crushed return flex run can throw the airflow balance of an entire floor out of whack. Repair here means more than tape and a prayer. We use a negative-pressure inspection process to locate exactly where the system is losing air, then apply the right fix for the material: mastic and fiberglass mesh for metal seams, replacement collars for flex connections, and proper strapping where support has failed. Repairs in Marietta typically run between $300 and $1,800 depending on how many points of failure exist and how accessible they are. Every repair is covered by our written guarantee, including a free second visit if the fix doesn’t hold.
Leak Sealing and Joint Repair
Metal duct systems in older Marietta neighborhoods like Fair Oaks and the historic district were put together decades ago, often with nothing but duct tape that has long since turned to dust. We remove the failed tape, clean the surfaces, and seal seams with mastic rated for the temperature swings an attic goes through. It’s the same repair, done with materials that outlast the original installation.
Crushed and Separated Flex Repair
When flex duct separates at the take-off collar, the conditioned air that should reach a child’s bedroom is instead blowing into the attic. We see this constantly in homes where attic work – cable runs, insulation blow-in, pest services – disturbed the runs. The repair is straightforward: re-attach at the collar with a proper connector and zip tie, then re-strap so it can’t sag again. The complication is getting to it before a full season of waste has already happened.
Duct Replacement
Duct Replacement is the complete removal of an existing duct system and the installation of new runs throughout the home – every supply line, return line, and plenum connection replaced with materials sized and sealed for the current system. It is the right call when a duct system is beyond incremental repair: when rust has perforated the metal trunk in multiple places, when the original design never worked correctly, when a remodel changed the home’s layout, or when a previous owner’s DIY work left the system leaking everywhere. In Marietta’s housing stock, which ranges from 1950s brick ranches in East Cobb to 2000s craftsman builds in West Cobb, we see both under-designed systems and well-installed systems that have simply aged out. Full duct replacement in a typical Marietta home runs between $4,500 and $11,000. The spread is wide because every attic, crawl space, and equipment layout is different. You’ll receive one written price before work begins – no per-vent pricing that climbs once the job is underway – and the entire replacement is covered by the 365-Day Done Right Promise.
Undersized System Correction
Some Marietta homes were never given the duct capacity their HVAC system deserves. Bedrooms at the end of long branch runs stay warm all summer, and the homeowner gets told it’s just the way the house is. It’s not. We replace undersized trunks and branches with properly sized ductwork, and rooms that haven’t been comfortable in years finally hold temperature.
Whole-Home Efficiency Replacement
When a furnace or heat pump in Marietta is being replaced with a new high-efficiency unit, pairing it with old, leaky ducts negates much of the upgrade. We coordinate with the HVAC contractor to replace the duct system during the equipment swap, so the new unit actually delivers its rated performance. The combined job comes with one written price for the duct portion, agreed before any material is ordered.
Ductwork Installation
Ductwork Installation is the design and physical installation of a new air distribution system, built to the calculated heating and cooling load of the specific home. Unlike repair or even replacement, installation starts from a blank slate – the layout is designed based on the home’s square footage, the equipment’s output, the number of rooms, and the realities of the attic or crawl space where the ducts will live. In Marietta, where many neighborhoods sit in a humid subtropical climate zone, the installation details determine whether your system works quietly and efficiently for 20 years or starts fighting itself within five. Key decisions include duct sizing per Manual D, insulation R-value on supply runs, sealed connections at every joint, proper support spacing, and return-air placement that doesn’t pull from the hottest part of the attic. Linden Air Duct Marietta performs ductwork installation for new equipment installs, home additions, and full replacements. A new duct system for a 2,000-square-foot Marietta home typically runs $5,500 to $12,000, with a single written price covering the entire job. No per-vent surprises, no added line items after the work starts.
Duct Design and Sizing
Installing flex duct off the shelf at whatever size fits is how you get a loud system with uneven temperatures. We design each run based on the CFM the equipment needs and the distance to the register. The result is a quieter, more balanced home, and the airflow numbers show up in the comfort of every room, not just the thermostat.
Equipment Matched Installation
A new heat pump in Marietta needs the ductwork that matches its airflow profile, not the remnant of a system installed in 1998. When we install new ductwork alongside a new HVAC system, we work with brands including Honeywell filtration and Aprilaire air quality products to make sure the air being moved is the air you actually want to breathe. The installation includes sealed plenums and properly supported runs, so the new equipment operates exactly as intended.
Brands We Service
Our technicians work daily with professional-grade diagnostic and cleaning equipment from Nikro and Rotobrush, which means the inspection that precedes any repair recommendation is thorough and trustworthy. When we tell you a duct section has failed, it’s because we’ve seen it on camera or measured the pressure loss, not because we guessed.
On the air quality side, we’re experienced with filtration and purification products from Honeywell, Aprilaire, and Abatement Technologies. Whether your Marietta home has a whole-house media filter, a UV purification system, or an Aprilaire dehumidifier integrated with the ductwork, we understand how the components interact and how to repair the duct system without compromising the air quality equipment. Whether you have Honeywell filtration, an Aprilaire system, or any other make, we can service and repair the surrounding ductwork to keep it all working as one system.

- Rooms that never reach temperature. One bedroom in your Marietta home stays ten degrees warmer than the rest of the house no matter how long the AC runs. This usually points to a disconnected or crushed duct run feeding that room. The longer it goes unfixed, the harder the rest of the system works to compensate, and the more your bill climbs.
- Dust accumulating within 48 hours of cleaning. If you wipe down surfaces and see a fresh layer of fine dust two days later, your return ducts may be pulling air from the attic instead of the rooms. A separated return line makes the system inhale insulation fibers and attic dust, then blow them through the house.
- A power bill spiking without explanation. Cobb EMC or Georgia Power bills that jump $40-$60 in a month with no change in habits often indicate the system is losing conditioned air into the attic or crawl space. That’s air you paid to heat or cool, escaping through a hole you can’t see from the living room.
- Weak airflow from multiple vents. If several registers are barely pushing air even when the blower is on high, the system has likely developed a major leak at the plenum or the main trunk. One vent being weak is a branch problem. Multiple weak vents usually means the problem is at the heart of the system.
- Whistling or hissing sounds from ductwork. A high-pitched noise when the system runs is often air escaping under pressure through a small separation or hole. It’s not just annoying – it’s a measurable leak that is costing you money every single cycle. Finding and sealing it is quick work for a pro with the right tools.

How Much Does Air Duct Repair Cost in Marietta?
A typical air duct repair in Marietta runs between $300 and $1,800 depending on the type and location of the failure. A single separated flex run that needs re-attaching at the take-off collar is on the lower end. A rusted metal trunk section that must be cut out and replaced in a tight crawl space sits higher. Sectional duct replacement where several attic runs have been crushed typically lands between $1,200 and $2,600. Full duct replacement in a Marietta home runs $4,500 to $11,000, and new ductwork installation for larger jobs falls between $3,800 and $12,000. Whatever the scope, you’ll receive a single written price before work starts.
What affects the price is plain: how many sections are damaged, how accessible they are, what material is being repaired, and whether the work requires attic or crawl space navigation. The cheapest quote in a pile is often the one that becomes expensive later – either through incomplete sealing, undersized replacement sections, or a surprise invoice at the end. The most effective way to avoid overpaying is to get the inspection done by someone who will show you the actual failure on camera before quoting the fix. Our estimates are free, they are in writing, and they are the final number. No add-ons, no discovered problems that quietly inflate the bill.
