Air Duct Replacement Cost Factors 

Air ducts are an important, but often overlooked, part of your HVAC system. Ducts need to be clean, tightly sealed, and in good condition. Otherwise, your HVAC will have to work harder and wear out faster trying to heat or cool your home. When considering whether it’s time to clean or replace your ducts, check out how these factors influence the cost of air duct replacement in Dallas, TX.

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 Dallas, TX, 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

Hiring an HVAC pro in Dallas, TX, is the fastest, safest way to replace your air ducts. Labor costs for this home improvement project are around $50 to $110 per hour, and most jobs take five to seven hours to complete.

The City of Dallas also requires a permit for HVAC work, including air duct replacement. The pro you hire will be able to handle the permit process and will fold the permit costs into your project total. Costs vary by project, so check in with your HVAC contractor or the city’s Building Inspection department for specific fees based on your project.

Additional Pros to Consider Hiring

An HVAC pro is the best person to hire for air duct replacement, but when replacing your air ducts, there are other projects you’ll likely want to do at the same time. From repairing insulation and drywall to testing for and removing mold and asbestos, here are the costs to hire a pro for the following projects in Dallas:

• Drywall repair cost: $260–$690

• Mold remediation cost: $1,370–$3,480

• Asbestos testing cost: $210–$530

• Insulation installation cost: $980–$2,430

Does Air Duct Replacement Increase Home Value?

Air duct replacement alone may not move the needle on your home value, but updated ductwork will make your property stand out to potential buyers. When combined with a new HVAC system, though, new air ducts could increase the value of your home by 5% to 7%, plus you (or the new homeowner) will save money every month on utility costs with a more efficient system.
