Air Duct Repair & Replacement in Greenville, SC
We inspect every section of your ductwork, repair the leaks and damage where it makes sense, and tell you honestly when full replacement is the better call.
Greenville's Trusted Air Duct Repair & Replacement Team
Air Today Heating & Cooling has been repairing and replacing ductwork across Greenville and the Upstate for over 45 years, and leaky or damaged ducts are one of the most common reasons we see HVAC systems underperforming. Most homeowners blame their AC or furnace when their bills climb, or certain rooms stop staying comfortable, but the U.S. Department of Energy estimates that up to 30% of the conditioned air moving through a typical home’s duct system is lost to leaks, gaps, and poor connections before it ever reaches the rooms you live in.
When you call us out, we inspect your full duct system, locate every leak and damaged section, and walk you through what we found before doing any work. If a targeted repair will fix the problem, we will tell you that. If a section is too damaged or undersized to be worth saving, we will explain exactly why replacement makes more sense and what your options look like. We will not push you toward replacement when a repair will do the job.
We show up on time, keep the work area clean, and make sure your system is running properly before we leave. That approach has kept us in business for nearly five decades, and it is why homeowners across Greenville keep calling us back when they need ductwork done right the first time.

Air Duct Repair
Our air duct repair work covers sealing leaks, fixing damaged sections, reattaching disconnected runs, and replacing small segments of duct without tearing out your full system. Repair usually makes sense when your ducts are structurally sound but have developed isolated leaks at joints, small holes from wear or pests, or sections that have come loose over time. Most homes only need targeted repair work, not a full replacement.
Our air duct repair includes:
- Inspect the full duct system for leaks, gaps, and damaged sections
- Test airflow and locate the specific points losing conditioned air
- Seal leaks at joints, seams, and connections with mastic or metal-backed tape
- Reattach disconnected sections and reinforce loose joints
- Replace small damaged sections of flex or rigid duct where needed
- Re-insulate exposed sections that have lost their original insulation
- Re-test airflow after repairs to confirm the system is working properly
If we find issues that go beyond a standard repair, we will walk you through your options before doing any additional work.
Air Duct Replacement & Installation
Replacement makes sense when your ducts are too damaged, too undersized, or too old to be worth fixing piece by piece. We recommend replacement when there are extensive leaks across multiple sections, crushed or collapsed flex duct, ductwork that was never sized properly for your system, mold or contamination that cannot be cleaned out, or duct runs that were installed decades ago and have outlived their useful life. A new duct system typically lasts 20 to 30 years and pays for itself through lower energy bills and better comfort across every room.
Our air duct replacement and installation includes:
- Full inspection and assessment of your existing duct system
- Manual J load calculation to size the new ducts properly for your home and equipment
- Removal and disposal of the old ductwork
- Design and installation of new rigid or flex ducts sized for your system
- Sealed connections at every joint with mastic, not tape alone
- Insulation on all ducts running through unconditioned spaces
- System balancing so each room gets the airflow it needs
- Full system test after installation to verify performance
We will walk you through every step before we start, so you know exactly what the work involves and what it will cost.
Air Duct Cleaning
Air ducts accumulate dust, debris, pet dander, and other contaminants over time. We recommend scheduling a cleaning when you start seeing visible dust around vents, musty odors when the system runs, worsening indoor allergy symptoms, recent renovations that pushed drywall dust into the system, or signs of rodent or pest activity.
A professional cleaning removes what your filter cannot catch and helps your system move air the way it should. Our air duct cleaning includes:
- Pre-cleaning inspection with cameras to assess the level of buildup
- Sealing of supply and return vents to create negative pressure across the system
- Use of professional-grade negative-pressure vacuum equipment, not shop vacs
- Agitation of debris from inside the duct walls with rotary brushes and air whips
- Cleaning of supply registers, return grilles, and the air handler interior
- HEPA filtration of all extracted debris so contaminants do not recirculate into your home
- Sanitizing treatment where mold or biological contamination is present
- Post-cleaning inspection to confirm the work is done properly
If we find leaks, damage, or other issues during the cleaning, we will let you know so you can decide whether to address them in the same visit.se
Air Duct Insulation
If your ducts run through unconditioned spaces like the attic, crawlspace, or garage, and the existing insulation has degraded, fallen off, or was never installed in the first place, you’ll need air duct insulation. Common signs include hot or cold spots in specific rooms, visible condensation or rust on duct surfaces, ducts that feel hot to the touch in summer, and energy bills that climb during the months your system runs the hardest.
In the Greenville climate, where attic temperatures can hit 130°F in July, and crawlspaces stay damp through winter, properly insulated ducts are one of the simplest ways to keep the conditioned air you already paid for from being lost to the surrounding space.
Our air duct insulation includes:
- Inspection of existing insulation to identify gaps, damage, and degraded sections
- Removal of damaged, wet, or contaminated old insulation
- Application of new insulation rated for the specific location (R-6 minimum for attics, higher where required)
- Vapor barrier installation to prevent condensation on cold-weather duct runs
- Sealing of all seams and joints in the insulation jacket
- Surface temperature testing after install to confirm the insulation is performing
If we find duct damage or leaks underneath the old insulation, we will walk you through your options before adding new insulation over a problem that should be fixed first

Frequently Asked Questions
Most air duct repairs in the Greenville area costs between $200 and $1,500, depending on how much of the system needs work and what kind of damage we find. A small leak or a single disconnected section sits at the lower end, while resealing multiple joints, replacing damaged flex runs, or re-insulating long sections runs higher.
We will give you an exact quote after inspecting your system, before any work starts.
Full air duct replacement in a typical Greenville home ranges from $3,000 to $10,000 or more, depending on the size of your home, the layout of the duct runs, and whether you need rigid sheet metal or flex duct. Smaller jobs replacing only one section of the system cost less, and complex jobs with attic access issues or significant rerouting cost more.
We will walk you through the full scope and price before any work begins.
Sheet metal ductwork typically lasts 20 to 30 years when it is well sealed and properly maintained. Flex duct usually lasts 10 to 15 years before the inner liner starts to break down or the outer jacket loses its insulation. If your home is over 25 years old and the ducts have never been replaced, it is worth having them inspected even if your system seems to be working fine.
The most common signs include certain rooms feeling hotter or colder than the rest of the house, energy bills climbing without a clear reason, weak airflow at some vents, excessive dust around supply registers, musty smells when the system runs, and visible damage to ductwork in the attic or crawlspace. If you notice any of these, it is worth scheduling a duct inspection.
Repair makes sense if the damage is isolated, the ducts are still structurally sound, and the rest of the system is in decent shape. Replacement is the better call if your ducts are over 20 years old, leaking in multiple places, undersized for your equipment, or contaminated with mold that cannot be cleaned out. We will inspect your full system and give you an honest recommendation based on what we find.
Some basic tasks like vacuuming around supply vents or replacing damaged register covers can be done without a professional. The duct system itself requires specialized tools, proper sealants like mastic, and access to areas like attics and crawlspaces that are dangerous to work in without training. Professional repair also means the work is pressure-tested afterward, so you know the leaks are actually fixed and not just covered up.
Yes, in most cases. The U.S. Department of Energy estimates that up to 30% of conditioned air is lost to duct leaks and poor connections in a typical home, which means your HVAC system has to run longer to keep up. Replacing failing ductwork with properly sized and sealed runs cuts that loss significantly, and most homeowners notice a difference on their next few energy bills.
