Trusted Air Duct Repair for Louisville Homeowners
Torn flex duct in an attic, a crushed run behind a finished wall, a joint that’s been leaking since the house was built – these are the reasons rooms never heat or cool right, no matter what you set the thermostat to. Dayspring Air Duct Cleaning repairs what we find, not just reports it. We’re led by Sal Maddox, and we’ve been serving Louisville since 2013, bringing professional-grade Rotobrush contact-cleaning systems and Nikro HEPA negative-air equipment into homes that have never had anything more than a shop vac pointed at a register. Every job starts and ends with one flat price per system, agreed before work starts, backed by before-and-after photos of your own ducts. Call (877) 517-3289. We answer 24/7, with fast dispatch from 7am to 7pm.
HVAC Duct Installation
HVAC Duct Installation is the full build-out of a duct system, usually as part of a major remodel, an addition, or replacing a design that never worked in the first place. You need it when the existing layout can’t be saved – runs that were sized wrong, or a home where one side stays 8 degrees off no matter what the equipment does. Dayspring Air Duct Cleaning plans the layout around how your rooms actually heat and cool, not around whatever trunk line is easiest to reach. Most whole-home installations in Louisville fall in the $3,000-$8,000 range, and the written estimate fixes the final figure.
System Design and Layout
We measure room loads and map the trunk and branch runs before anything gets cut. Getting the sizing right up front is what separates a system you never think about from one you fight with every season.
New Runs and Register Placement
Where a supply lands in a room matters as much as how much air it moves. We route new runs to keep transitions smooth and put registers where the conditioned air actually reaches people.

Air Duct Replacement
Air Duct Replacement is pulling out ductwork that’s beyond repair and installing new duct in its place – common in older Louisville homes where the original runs were wrapped in failing insulation or built from materials that have simply given out. You need it when the damaged sections outnumber the sound ones, or when a leak has been unsealed long enough that the duct itself is compromised. We pull the old system cleanly and rebuild with sealed, properly sized duct. Typical whole-home replacements run $2,500-$6,500 depending on length and how much is accessible. The written estimate sets the price.
When Repair Stops Making Sense
One failed joint is a repair. A trunk with five of them, plus insulation falling off in sheets, is a replacement. We’ll show you the difference rather than push the bigger job.
Managing Access and Cleanup
Replacement work means opening walls and ceilings, so we plan the route before demolition and contain the work area. HEPA equipment from Nikro keeps dust where the work is, not in the rest of your house.
Ductwork Repair
Ductwork Repair covers the fixes that stop the leaks: reconnecting separated joints, sealing seams, patching holes, straightening crushed flex runs, and re-supporting sagging duct that’s lost its shape. You need it when a room doesn’t hold temperature, when you hear whistling at a register, or when an inspection flags disconnected duct in an attic or crawl space. We repair what we find using mastic and proper mechanical fastening, then verify the fix under airflow. Most ductwork repair jobs in Louisville run $250-$900, and the estimate is free.
Sealing Leaks You Can’t See
Leaky joints pull attic air into your living space, and that’s air you didn’t pay to condition. Sealing seams and connections is the cheapest way to reclaim lost capacity before considering bigger work.
Crushes, Kinks, and Worn Flex
Flex duct that has collapsed in insulation or pinched behind a joist moves almost no air. We straighten or replace those runs so the register puts out what it’s supposed to.
Duct Replacement
Duct Replacement is targeted replacement of damaged sections rather than the whole system – the middle road between a small repair and a full rebuild. You need it when one or two runs are torn or crushed beyond saving while the rest of the layout is sound. We pull the failed sections, match the material and sizing to the existing system, and seal the new pieces in so the repair holds. A single-run duct replacement in Louisville typically runs $350-$900, with multi-run jobs priced by the written estimate. Call (877) 517-3289 for a free estimate.
Matching the Existing System
New duct has to move the same air as what it replaces, or the room goes out of balance. We measure the old run before we cut, so the replacement lands where the original was supposed to.
Insulation and Vapor Sealing
In a Kentucky attic, uninsulated duct sweats in summer and loses heat in winter. We replace with properly insulated duct and seal seams so moisture stays out of the system.
Ductwork Installation
Ductwork Installation is adding new duct runs to an existing system – for a finished basement, a converted garage, a sunroom, or any space that never had a supply. You need it when a room is heated by a space heater or cooled by a window unit because no duct reaches it. We tie new runs into the existing trunk with correct sizing and dampers so the rest of the house doesn’t lose pressure. Adding runs to a home in Louisville usually runs $400-$1,200 per zone depending on distance from the trunk. The written estimate fixes the final price before any work starts.
Tying Into the Existing Trunk
A new run steals air from the old ones unless it’s balanced. We size the takeoff and add a damper so the new space gets service without robbing the rooms that already worked.
Extending Into Unfinished Space
Attics and crawl spaces are where most additions get complicated, because the duct has to be insulated and supported the whole way. We run it so it lasts as long as the house does.
Brands We Service
We work alongside the air-quality equipment already in your home. That means Honeywell filtration and control components, Aprilaire humidifiers and media cabinets, and Abatement Technologies filtration equipment – and because we’re trained to work around those systems, cleaning and repair don’t disturb settings you’ve had dialed in. Guardsman-grade practices guide how we handle managed and multi-unit properties, where the same standard has to hold across every unit in the building.
Rotobrush contact-cleaning systems do the deep work on duct walls, while Nikro HEPA negative-air machines hold the dust under control while we’re there. Whether you have Honeywell, Aprilaire, Abatement Technologies, or any other make, we can help – and if a repair involves a section the filtration equipment depends on, we make sure it goes back exactly as it should.

- Rooms that never hold temperature. A room that’s always cold in winter or hot in summer usually has a duct problem behind the wall, not a thermostat problem. A disconnected or crushed run is common in Louisville homes with long attic runs.
- Whistling or weak airflow at registers. A register that hisses or barely moves air is telling you the duct behind it is restricted or leaking. That’s a symptom worth diagnosing before the system works harder and fails somewhere expensive.
- Visible dust streaks near vents. Dust blowing back out of a register means the duct is leaking and pulling unfiltered air in. It’s the kind of thing that gets worse quietly until you notice the filters are always dirty.
- Higher energy bills with no change in use. Leaky duct means your HVAC equipment runs longer to do the same job. If the bill has climbed and nothing else changed, get the duct checked.
- Musty smell when the system starts. A musty odor at startup usually means moisture in the duct or attic air being pulled in through a gap. That’s worth a professional look rather than a filter swap.
Our Process, Step by Step
- 1
Inspection and photos. We open access points and show you what’s actually inside the system – torn runs, disconnected joints, crushed flex – with photos before we touch anything. You see what we see.
- 2
Written estimate, flat rate per system. We price the whole job, not per vent and not with a teaser number. The estimate you agree to is the price you pay.
- 3
Containment and cleaning. Nikro HEPA negative-air equipment holds dust under control while Rotobrush contact cleaning does the deep work on the ducts. If the job calls for cleaning as well as repair, it happens in the same visit.
- 4
Repair or replacement. We reconnect, seal, straighten, or replace damaged sections as the estimate calls for. When a repair involves a filtration component from Honeywell or Aprilaire, it goes back exactly as it should.
- 5
Verification and before-and-after photos. We confirm airflow and show you the before-and-after so you know the work was actually done. Cleaner air isn’t a feeling – it’s a result you can measure.
How Much Does Air Duct Repair Cost in Louisville?
Most air duct repair in Louisville runs $250-$900, depending on what’s damaged and how easy it is to reach. That’s the range for the common jobs, and the written estimate gives you the exact figure before work starts.
A typical ductwork repair to seal leaks or reconnect separated joints runs $250-$450. Painpoint section-by-section replacement of damaged runs typically runs $350-$900. Pulling out and replacing the whole system, where the old duct is beyond saving, runs $2,500-$6,500. Adding a new run to an existing system runs $400-$1,200 per zone, and full HVAC duct installation in a remodel or addition typically runs $3,000-$8,000.
What moves the price: how many runs are damaged, whether the problem is in an accessible attic or buried behind finished walls, and whether the system is flex, rigid metal, or a mix. Accessibility matters more than most homeowners expect – a leak behind drywall costs more to reach than the same leak in an open attic.
How to avoid overpaying: get a written estimate before any work begins, and make sure it prices the whole system rather than per vent. A flat price per system is the honest way to do this – a low opening number that grows once the crew is on site is the industry’s old bait-and-switch, and it costs you more in the end.
What’s included in our free estimate: the inspection itself, the photos showing what we found, and a written price for the repair as a whole. No service-call fee, no diagnostic fee, no number that shrinks once it’s on paper. Call (877) 517-3289 for a free estimate – we answer 24/7, with fast dispatch from 7am to 7pm.

Frequently Asked Questions About Air Duct Repair in Louisville
Air duct repair is fixing the physical damage inside your duct system – reconnecting separated joints, sealing leaks, patching holes, straightening crushed flex runs, and replacing sections that can’t be saved. It’s different from duct cleaning, which removes dust and debris but doesn’t fix damaged duct. Dayspring does both, so you don’t need to call a second contractor. Call (877) 517-3289 for a free estimate.
Most duct repair jobs take a few hours to a full day, depending on how much is damaged and how accessible the runs are. A single run or a few sealed joints can often be finished in the morning. A full replacement with wall access takes longer, and we’ll tell you the expected timeline in the written estimate. We dispatch 7am to 7pm, Sunday through Friday, closed Saturday.
Most air duct repair in Louisville runs $250-$900, with full system replacement running $2,500-$6,500. Small targeted repairs sit at the low end; multiple runs or hard-to-reach damage land higher. The written estimate gives you the exact figure as one flat price per system, agreed before work starts. Call (877) 517-3289 for a free estimate – estimates are free.
We use Rotobrush contact-cleaning systems and Nikro HEPA negative-air equipment on every job, not consumer shop-vac setups. If your home already has filtration components from Honeywell or Aprilaire, we work around them so cleaning and repair don’t disturb settings that are already set the way you want them. Call (877) 517-3289 and tell us what’s installed in your system.
Same-day service is available depending on the schedule, and we answer the phone 24/7. Fast dispatch runs from 7am to 7pm, Sunday through Friday, and we’re closed Saturday. A call outside dispatch hours is booked into the next opening. Call (877) 517-3289 and we’ll get you scheduled.
We stand behind our repairs and go over the warranty terms with you at the time of the written estimate. If a repaired section fails, call (877) 517-3289 and we’ll take a look. The details are in writing before any work begins, so there are no surprises.
Clear access to the registers and any attic or crawl space hatch, and move furniture away from the walls where we may need to work. If you have pets, secure them during the visit. Beyond that, you don’t need to do anything – we bring the containment equipment and handle cleanup. Call (877) 517-3289 with any questions before we arrive.
