What Does Air Duct Replacement Cost?

Air duct replacement is usually priced by linear foot or as a whole-home scope. Most homeowners see total projects between $3,500 and $11,000 for a typical single-family home, depending on size, material, and access. Larger or complex homes can extend beyond that.

Typical price drivers include:

1. Home size and layout
   • More square footage and longer runs require more materials and labor.
2. Material type
   • Sheet metal, flex, or fiberglass duct board have different costs and lifespans.
3. Access and obstacles
   • Tight crawlspaces, finished basements, or asbestos remediation add time and cost.
4. Code upgrades and insulation
   • R-8 insulation, sealing, and hangers to meet code increase investment but reduce losses.
5. Add-on IAQ options
   • Filtration, UV lights, and balancing improve health and comfort.

Denver homeowners should also plan for altitude-driven system sizing, older ranch homes with long basement runs, and wildfire smoke season that makes tight, sealed ducts a smart upgrade.

Signs You Need Replacement vs. Repair or Cleaning

Replacing ducts is not always necessary. Start with a professional inspection and testing.

Replace ducts when you see:

• Widespread kinks, crushed sections, or collapsed flex runs
• Extensive rust, mold, or water damage on metal ducts
• Missing or failing insulation throughout the system
• Major design problems like undersized trunks and poor return placement

Repair or clean when you see:

• A few loose connections or small leaks
• Minor dents or a short damaged section
• Dust and debris buildup that affects airflow and indoor air quality

Our team offers inspection, cleaning, sealing, repair, and custom ductwork solutions. You get the right fix at the right price, not a one-size quote.

Cost Ranges by Material

The material you choose affects both cost and performance.

• Sheet metal ducts
  • Highest durability and smooth airflow
  • Common for main trunks and long straight runs
• Insulated flex duct
  • Cost effective and quick to install
  • Best for short branches with gentle bends
• Fiberglass duct board
  • Good thermal and acoustic properties
  • Used in specific design cases

A balanced system often blends a sheet metal trunk with flex branches. The mix depends on your layout, local code, and performance goals.

Whole-Home Replacement by Home Size

Every home is unique, but these planning ranges help set expectations.

• Small home or condo
  • 1 to 2 bedrooms, shorter runs
  • Often minimal redesign unless prior mistakes exist
• Mid-size single family
  • More branches and balancing
  • May need new returns to improve airflow
• Large or multi-story home
  • Zoning considerations, larger trunks, and advanced balancing

We tailor custom ductwork design to your property so the new system supports comfort in every room.

What Drives Labor and Time

Labor can be half or more of the total. The following increase hours on site:

• Finished spaces that require careful demo and patching coordination
• Attic or crawlspace work in hot or tight areas
• Structural obstructions and rerouting
• Permitting and inspections that require staged visits

A typical project includes removal of failing sections, layout confirmation, fabrication or cutting, sealing, strapping and support, insulation, and commissioning with airflow testing.

Add-Ons That Improve Comfort and Health

Ductwork is the highway for your air. Upgrades pay you back in comfort and cleanliness.

• Professional duct sealing
  • Reduces energy waste and hot or cold spots
• Proper insulation and vapor barriers
  • Protects against condensation and heat gain or loss
• Filtration and indoor air quality enhancements
  • Air filtration systems, UV germicidal lights, and duct cleaning improve air quality
• Balancing and new return placement
  • Eases static pressure and improves room-by-room comfort

Our integrated IAQ approach pairs duct services with filtration and UV sanitization for cleaner, healthier air.

Denver-Specific Advice That Saves Money

Front Range homes often have long trunk runs in basements and utility spaces. Air leaks in these areas waste conditioned air and pull in dust. During wildfire smoke season, leaky returns draft odor and particulate into your living areas.

Smart local moves:

1. Seal and insulate ducts in unconditioned spaces to reduce energy loss.
2. Add a dedicated return on upper floors to relieve pressure and improve cooling.
3. Schedule work in shoulder seasons to secure faster timelines and better availability.
4. Combine duct replacement with system maintenance to reduce total visits and fees.

When Cleaning or Sealing Is Enough

Not every issue requires a full replacement. If your ducts are structurally sound, targeted sealing and a professional cleaning can lift performance and indoor air quality at a fraction of the cost. Fix-it 24/7 offers:

• Ductwork inspection to ensure optimal airflow and air quality
• Air duct cleaning to remove contaminants and allergens
• Duct cleaning and sealing to stop leaks and improve efficiency

This step-by-step approach keeps your investment focused on what matters.

Frequently Asked Questions

How much does air duct replacement cost in the Denver area?

Most homes fall between $3,500 and $11,000 depending on size, materials, access, and code upgrades. Complex layouts, finished spaces, and add-on IAQ features increase price.

If ducts are structurally sound, professional cleaning and sealing can improve airflow and efficiency at a lower cost. Replacement is best for severe damage or bad design.

What material should I choose for new ducts?

A common choice is a metal trunk with insulated flex branches. The right mix depends on your layout, budget, noise goals, and local code requirements.

How long does a duct replacement take?
