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

Properly functioning ductwork is essential to staying comfortable in Detroit’s hot summers and frigid winters. Air duct replacement costs in Detroit are $638 on average, with rates ranging from $382 to $914 depending on the size of your home, the type of ductwork you have, and where the ducts are located.

Air Duct Replacement Cost Factors 

Duct replacement costs can range widely based on a number of different factors. Consider how these common factors can influence the cost of your duct replacement project.

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:

Duct Material

The material you choose for your replacement ducts affects both their cost and longevity. The most commonly used duct material in Detroit, MI, is metal sheeting.

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

Labor makes up 60% of the final cost of air duct replacement. Rates are $50 to $110 per hour, with most jobs taking five to seven hours. 

You’ll also need a permit for duct replacement from the Buildings, Safety Engineering, and Environmental Department in Detroit. A mechanical permit for duct replacement is $200, while a permit for alterations to ductwork is $105. Your HVAC pro can handle the permit process for you.

Always leave duct replacement to a local HVAC pro in Detroit, MI, or you could risk failing home inspections or voiding your home insurance policy coverage.

Additional Pros to Consider Hiring

While an HVAC pro is the best person to hire for duct replacement, you may need additional experts to repair drywall, remove mold or asbestos, or follow up with additional insulation. Here’s what you can expect to pay to hire pros for these jobs in Detroit:

• Drywall repair cost: $320–$970

• Mold remediation cost: $1,030–$2,520

• Asbestos testing cost: $130–$730

• Insulation installation cost: $1,260–$2,660

Does Air Duct Replacement Increase Home Value?

Air duct replacement can slightly increase the value of your home, especially if you’re replacing old, inefficient, and dirty ductwork. In combination with a new HVAC system, air duct replacement could boost your home’s value by 5% to 7%. Plus, having new ducts with better insulation and no leaks means you’ll save month after month with lower utility bills.
