How Much Does Air Duct Replacement Cost in Atlanta? [2025 Data]

In Georgia’s capital, you’ll spend an average of $862 to replace your ductwork, with most air duct replacement costs in Atlanta ranging from $435 to $1,290. Your final price will depend on a few variables, including the size of your house and the type and location of your ductwork. Let’s take a closer look at how these factors come together.

Air Duct Replacement Cost Factors 

Before calling a pro to replace your air ducts in Atlanta, GA, it helps to have an idea of what you might pay for this project. Let’s break down the main cost factors.

Size

The size of your home directly affects air duct replacement costs. Larger homes require more materials and labor to replace the entire 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:

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:

Does Air Duct Replacement Increase Home Value?

In case you’re looking to sell, replacing damaged air ducts can increase your home’s desirability in the eyes of potential buyers. Getting rid of any old, leaky, or inefficient ductwork can put the future owners at ease since they’ll know that they won’t have to take on that project themselves (at least for the next several years).

Something else to consider: If other parts of your HVAC system (like your AC unit or furnace) need an upgrade, it’s smart to replace them when installing your new ductwork. By adding a new HVAC system, you could see a 5% to 7% rise in your property’s value.

Duct Material

The material you choose for your replacement ducts affects both their cost and longevity. The most common types of ducts in Atlanta, GA, are metal and flexible ductwork.

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: 

HVAC Pro Costs

On top of the ductwork itself, you’ll also need to budget for some additional costs, including permits and sales tax. HVAC pros in Atlanta charge $47 to $95 per hour. 

Licensing and Certification

It’s important to hire a licensed HVAC professional to replace your ductwork. If you try to tackle this project yourself, you could damage your HVAC system, reduce your house’s energy efficiency, or run into issues with your homeowners insurance or home warranty. In Georgia, pros who perform HVAC work must have a Conditioned Air Contractor license.

Permits

To install or replace HVAC equipment (including ductwork), you’ll need a mechanical permit from the City of Atlanta. The base fee for these permits is $150.

While you can pull the permits yourself, it’s easier to let your contractor handle this part of the project. A good HVAC pro in Atlanta, GA, will know how to navigate the city’s permitting process and secure the right ones for your job.

Sales Tax

It might seem like a minor expense, but you should still keep sales tax in mind when budgeting for air duct replacement in Atlanta. The city’s combined sales tax rate is 8.9%, so if you need $600 worth of materials, for example, you’d pay an extra $53 in tax.
