Highlights
Ductwork can be replaced completely or, for minor problems, in patches.
The cost of duct replacement increases by $1,300 or more for each additional 1,000 square feet of living space.
Expect to pay double or even triple for ductwork replacement in harder-to-reach areas, like attics or crawl spaces.
Sheet metal is the most expensive ductwork material, but it’s also highly durable and efficient, making it an excellent choice.
If you choose a budget-friendly duct material, you’ll spend more ($1 to $8 per square foot) to insulate the ducts.
The average cost for air duct replacement in Indianapolis, IN, is $670. The standard range is between $220 and $1,181, although actual project costs will depend on the scope and complexity of the work. For example, it will cost more to replace air ducts in areas like attics and crawl spaces that are harder to access than ceilings or walls. Owners of larger homes will also pay more because there’s more work—and more ducts—involved.
Air Duct Replacement Cost Factors
If you’re an Indianapolis-area homeowner, you can use these average costs as a guideline, but know that there are other factors affecting the total project cost.
The size of your home, for example, is a major factor. After all, installing more ductwork in a larger home will cost more. Where the ductwork is located also matters. The type of ductwork also impacts your final cost since material prices vary (plus, additional insulation will cost you more).
Size
The size of your home directly affects air duct replacement costs. Larger homes require more materials and labor to replace the entire air duct system. On average, the cost ranges from $2,000 to $5,000 for a small- to medium-sized home. However, duct replacement can run as low as $1,400 for smaller homes and as high as $9,000 for larger homes. Here’s how the size of your home affects duct replacement costs:
| Home Size (Sq. Ft.) | Average Cost |
|---|---|
| 1,000–2,000 | $1,246–$4,005 |
| 2,000–3,000 | $2,492–$5,963 |
| 3,000–4,000 | $3,738–$8,010 |
Duct Location
If only specific sections of your ductwork need replacement, such as in a renovation project, costs will depend on the location of the damaged or worn ductwork. Replacing ducts in hard-to-reach or concealed areas—like attics, basements, ceilings, walls, or crawl spaces—can increase labor costs. Here’s how the location of the ducts could affect their cost:
| Location | Average Cost |
|---|---|
| Exposed | $623–$2,670 |
| Wall or ceiling | $890–$3,560 |
| Basement | $1,602–$2,759 |
| Attic | $1,958–$4,984 |
| Crawl space | $2,670–$6,497 |
Duct Material
The material you choose for your replacement ducts affects both their cost and longevity. The most commonly used duct material in Indianapolis, IN, is sheet metal, although fiberglass and flexible ductwork are also seen here, depending on the home and its energy needs.
Sheet metal ducts are durable but pricey. Flexible ducts, on the other hand, are more affordable but may need to be repaired or replaced sooner. Here’s a breakdown of air duct replacement costs based on duct material:
| Duct Material | Average Cost per Linear Foot |
|---|---|
| Flexible (non-insulated) | $1–$3 |
| Flexible (insulated) | $2–$4 |
| Fiberglass | $4–$6 |
| Fiberboard | $3–$5 |
| Sheet metal | $7–$13 |
HVAC Pro Costs
HVAC pros in Indianapolis charge between $50 to $100 per hour, with an air duct replacement project taking five to seven hours to complete. Larger projects in larger homes will take longer, increasing the cost of both materials and labor. For any project, expect that the cost will be divided 40% for materials and 60% for labor. This means that a project costing $5,000 is actually $2,000 for materials and $3,000 for labor.
If you need the work done immediately, you will probably pay a premium for emergency service. Prices will also increase if there’s mold growth or other damage to the air ducts that affects the operation of your HVAC system.
Pro Tip
Quality ductwork will increase the efficiency of your HVAC, sometimes by 20% to 30%. This is because there is reduced air leakage due to better insulation and more optimized airflow. This means your HVAC doesn't have to work as hard to keep the desired temperature, so it uses less energy.
Sales Tax
If you’re planning air duct replacement work in your Indianapolis home, don’t forget about the 7% sales tax that gets added to the project price. This means that if your project costs $3,000, it will cost $3,210 with tax.
Does Air Duct Replacement Increase Home Value?
While it is a good thing to have a well-maintained HVAC system in your home, air duct replacement itself won’t increase home value. However, home buyers will appreciate having less work to do after moving in, so new ductwork could be the push they need to make an offer on your home. For a true boost to your home value, you’ll need a whole new HVAC system, which can increase the value of your home by 5% to 7%.
