Trusted Air Duct Repair for Winston-Salem Homeowners
Air duct repair in Winston-Salem usually means one of three things: a joint that has pulled apart, a run that is crushed or kinked, or a section of flex duct that has torn and is leaking air into an attic or crawlspace. Left alone, each one sends conditioned air somewhere other than the rooms you’re paying to heat and cool, and pulls dust and insulation fibers into the supply stream. Our technicians have up to 13 years of experience diagnosing exactly that, and we carry professional-grade Rotobrush and Nikro equipment so we can inspect, repair, and clean the same system in one visit. We answer 24/7 and offer same-day service when the schedule allows. Call (844) 834-1338 to book a free estimate.
HVAC Duct Installation
HVAC Duct Installation is the design and build-out of a duct system for a new addition, a converted garage, a finished basement, or a house where the original layout was never sized correctly. You need it when a room has never held temperature, when you’re adding conditioned space, or when a previous installer ran one trunk where two were needed. Delmar Air Duct Cleaning handles the full scope: we map the existing layout, size the runs, seal the joints, and balance airflow before we leave. Typical pricing for HVAC duct installation in Winston-Salem runs $1,800 to $6,500 depending on the number of runs, the length of the trunk, and whether the work is in open framing or finished ceilings. The estimate is free, and the written estimate sets the final price.
Sizing and Layout Planning
Every installation starts with a room-by-room airflow calculation so each register gets the volume it needs. We check static pressure at the air handler before and after, because a system that was starved for air before the work will still be starved if the trunk stays undersized. Getting this right up front is the difference between a comfortable room and a noisy vent that never quite catches up.
Sealing New Joints and Transitions
We seal the joints, collars, and plenum connections on every new run, since gaps at transitions leak a surprising share of the air before it reaches a room. Sealed connections also keep attic insulation fibers and crawlspace dust out of the supply stream. New ductwork is worth little if the seams reopen in a season, so we fasten and seal as we go.

Air Duct Replacement
Air Duct Replacement is the removal of a failed duct system and the installation of new ductwork in its place, and it’s the right call when the existing runs are deteriorated beyond patching. You need it when flex duct has collapsed inside the jacket, when the liner has shed into the airstream, or when an older system has been patched so many times that no single repair will hold. Delmar Air Duct Cleaning removes the old runs, disposes of the material, and installs new ductwork sized to the current equipment. Air duct replacement in Winston-Salem typically runs $2,200 to $7,000 depending on system size and access. The written estimate sets the final price, and the estimate itself is free.
Torn Flex Duct and Collapsed Runs
Flex duct fails quietly. It tears at the collar, sags between hangers, or pinches shut around a corner, and the room at the end of that run goes flat. We scope the run to confirm the damage before recommending replacement, because a pinch near a hanger is often fixable without pulling the whole line.
When Patching Stops Working
Patching makes sense for one or two isolated breaks. Once several sections of a system have been repaired, the remaining ductwork is usually the same age and in the same condition as the parts that already failed. At that point replacement costs less over time than repeat callbacks, and it lets us clean and seal a system that will actually hold.
Ductwork Repair
Ductwork Repair is the targeted fix for damage in an otherwise serviceable system, and it’s what most homeowners actually need. You need it when you notice a whistling register, a room that won’t heat, dust settling on furniture faster than usual, or debris visible at a vent. Common causes in Winston-Salem homes include disconnected joints, crushed flex runs, and seams that have separated in the attic heat. Delmar Air Duct Cleaning locates the break with a camera and pressure readings, then repairs and seals it. Ductwork repair in Winston-Salem usually runs $250 to $1,200 depending on how many breaks we find and whether they’re in open or finished space. The estimate is free and the written estimate sets the final price.
Leaks at Joints and Collars
The joint where a run meets the trunk or the boot is the most common failure point we find. Air escaping there never reaches the register, and it pulls attic or crawlspace air into the system instead. Sealing those connections is a quick fix with an outsized effect on comfort.
Crushed and Kinked Flex Runs
Flex duct that bends tighter than it should loses most of its capacity, and the register it feeds goes quiet. We straighten and re-hang the run where the space allows, and replace the section when the duct has been permanently deformed. Short runs and tighter radius bends hold up far better than long, sagging lines.
Duct Replacement
Duct Replacement is the swap of one duct section or an entire system for new material, and it’s usually driven by age or material failure rather than a single break. You need it when the duct board inside an older system has begun to break down, when rigid metal has rusted through at the seams, or when the existing ductwork simply can’t be sealed well enough to be worth repairing. Delmar Air Duct Cleaning removes the failed material and installs ductwork sized correctly for the equipment it serves. Duct replacement in Winston-Salem generally runs $600 to $3,000 for a partial replacement and $2,200 to $7,000 for a full system, depending on run count and access. Every price is an estimate, and the written estimate sets the final price.
Duct Board and Liner Breakdown
Older duct board can degrade until particles shed into the airstream every time the blower runs. Once the interior surface starts to break down, cleaning it won’t restore it, and replacement is the honest answer. We confirm the condition with a camera before recommending the swap.
Rigid Metal and Seam Failure
Rigid metal ductwork can last a long time, but the seams and connections are where it fails first, especially in an attic that swings between hot and cold. When the seams rust through, sealing becomes a losing game. Replacing the failed sections restores both the seal and the airflow.
Ductwork Installation
Ductwork Installation is the build-out of new runs where none exist, and it comes up when a room is being added, a system is being moved, or a previous installation left a space with no supply at all. You need it when a room has a return but no supply, when an addition was finished without ducting, or when a renovation moved walls and left registers in the wrong place. Delmar Air Duct Cleaning designs the layout, installs the runs, and balances the airflow before finishing. Ductwork installation in Winston-Salem typically runs $450 to $1,400 per new run depending on length, access, and whether a return is included. The estimate is free and the written estimate sets the final price.
Adding Runs to an Existing System
Adding a run means checking that the existing trunk and blower can carry the extra volume without starving the rooms already connected. We measure static pressure before adding anything, because an overloaded trunk makes the whole system worse rather than better. When the trunk can’t carry it, we say so before the work starts.
Returns and Airflow Balance
A supply run with no return path pressurizes the room and pushes air out through the gaps in the building envelope. We size returns alongside supplies so the system moves air the way it was designed to. Balancing the system at the end is part of the job, not an add-on.
Brands We Service
We work with Honeywell and Aprilaire air quality equipment, which means a cleaning or repair visit can also address the filtration and humidity control connected to your ductwork. When a Honeywell or Aprilaire component sits inline with the ducts, we know how it’s mounted, what it needs for clearance, and where the connections tend to work loose over time. Cleaning a system without accounting for that equipment can leave it working against you.
Our cleaning and repair work relies on Rotobrush and Nikro equipment, and we use Guardsman products where the application calls for them. Whether you have Honeywell or any other make, we can help. Brand names guide how we approach the system; they don’t change how we price the work, and they aren’t a claim of dealership or certification. If a component needs a manufacturer-specific part, we’ll tell you upfront rather than improvise.

AfterSigns You Need a Pro Right Now
- Whistling or roaring at a register. A vent that’s louder than the others usually means a restriction or a separated joint nearby. The noise is air escaping, and it’s costing you comfort in the room it’s supposed to serve.
- A room that never holds temperature. One cold room in winter and a warm one in summer points to a duct problem more often than an equipment problem. A crushed run or a disconnected joint will do exactly that.
- Dust settling faster than it used to. When surfaces cloud over within a day or two, the system may be pulling dust from an attic or crawlspace through a break. Sealing that break stops the source rather than filtering the symptom.
- Visible debris or insulation at a vent. Bits of insulation or dark streaks around a supply register suggest the duct interior has failed or a connection has opened. That material is entering the air you breathe, so it’s worth a look soon.
- A musty smell when the system runs. Odor that appears only when the blower kicks on usually traces to moisture or organic growth inside the ductwork. Repair and cleaning together address the cause; cleaning alone often doesn’t.
Our Process, Step by Step
- 1
Phone conversation and scheduling. We ask what you’re seeing and hearing so we arrive with the right equipment. Call (844) 834-1338. We answer 24/7, and fast dispatch runs from 7am to 7pm, Sunday through Friday.
- 2
Full-system inspection. We open access points, run a camera through the runs, and check static pressure at the air handler. That combination tells us whether a break is isolated or the system is failing in several places.
- 3
Written findings and a flat price. You get a written estimate covering the repair, one flat price for the system, agreed before any work starts. No per-vent pricing and no surprise line items once the technician is on site.
- 4
Repair and mechanical cleaning. We make the repair, then use Rotobrush rotary brush equipment and Nikro tools to agitate and extract debris from the duct interiors. Containment and controlled air pressure keep dust out of your living space during the work.
- 5
Before-and-after photos and a walkthrough. We show you pictures of your own ducts from before and after, so you can see what changed. Then we walk the system with you and explain anything that needs attention later.
How Much Does Air Duct Repair Cost in Winston-Salem?
Most air duct repair in Winston-Salem falls between $250 and $1,200, with the total driven by how many breaks we find and where they sit. A single disconnected joint in an accessible attic is at the low end. Several separated collars plus a crushed run in finished ceilings pushes toward the top. A typical ductwork repair in Winston-Salem runs $250 to $1,200 depending on the number of breaks and access. A typical partial duct replacement runs $600 to $3,000, and a full air duct replacement runs $2,200 to $7,000.
What moves the number: how many runs are damaged, whether the work is in open framing or behind drywall, and whether the ducts need cleaning while they’re open. A repair in an attic with room to move costs less than the same repair over a finished ceiling. Sealing materials and new flex or metal sections are part of the estimate, not added later.
To avoid overpaying, ask for the findings in writing and compare the scope rather than the headline price. A quote that doesn’t say how many breaks it covers isn’t a quote you can compare. Our estimate is free, the price is set per job, and the written estimate sets the final price. You’ll know what the work involves before anyone starts.

Frequently Asked Questions About Air Duct Repair in Winston-Salem
Air duct repair is the fix for physical damage to your ductwork: a disconnected joint, a crushed or torn flex run, a failed seam, or a broken collar where a register connects. It’s different from cleaning, which removes debris from an intact system. In most Winston-Salem homes, the damage is in the attic or crawlspace runs rather than the trunk line.
Most single-break repairs take one to three hours on site, including inspection and sealing. Multi-run repairs or a partial replacement can take most of a day. We tell you the expected window when we book, so you can plan around it.
Air duct repair typically runs $250 to $1,200 depending on how many breaks we find and whether they’re in open or finished space. Partial duct replacement runs $600 to $3,000, and full replacement runs $2,200 to $7,000. Every price is an estimate, and the written estimate sets the final price. Call (844) 834-1338 for an exact quote; estimates are free.
Yes. We work with Honeywell and Aprilaire air quality equipment connected to ductwork, along with Guardsman products where the application calls for them. When that equipment sits inline with your ducts, we account for it during inspection and repair. We also use Rotobrush and Nikro equipment for the cleaning and repair work itself.
Same-day service is often available depending on the schedule, and we’ll tell you honestly when you call whether it fits. We answer 24/7. Fast dispatch runs from 7am to 7pm, Sunday through Friday, and we’re closed on Saturday. A call outside dispatch hours is booked into the next opening, Sunday through Friday, 7am to 7pm.
We don’t publish a warranty figure here because the terms depend on the specific repair and materials used. What we do commit to is one flat price per system agreed before work starts, and before-and-after photos of your own ducts so you can see the work was done. Ask about the workmanship terms for your job when we provide the written estimate.
Clear access to the attic hatch, crawlspace entry, and any closets with duct registers, and move breakables away from those paths. If you know where the air handler is, have that accessible too. Beyond that, there’s nothing to prepare; we bring the equipment and containment materials.
