Ductwork Replacement Cost in 2026: What Homeowners Pay
Key Takeaways
- Full ductwork replacement costs $1,400 to $5,600 in 2026, with a national average near $3,000 for a typical single-family home.
- Installed ductwork runs $25 to $55 per linear foot, so home size and layout drive most of the total price.
- Leaky or crushed ducts waste 20% to 30% of the conditioned air an HVAC system moves, raising monthly energy bills.
- Sealing existing ducts costs $1,100 to $4,000 and often fixes airflow problems without a full replacement.
- A home warranty helps cover duct repair from normal wear, but not replacement driven by remodeling or code upgrades.
Ductwork replacement cost in 2026 runs $1,400 to $5,600 for most single-family homes, with a national average of roughly $3,000. Installed ducts are priced at $25 to $55 per linear foot, so the biggest driver is the square footage and layout of your home. Small repairs to a single damaged run cost far less, usually $200 to $700, and sealing leaky ducts instead of replacing them typically costs $1,100 to $4,000. Homes with attic or crawl-space access, aging metal ducts, or an HVAC system replacement happening at the same time sit at the higher end of the range.
How Much Does Ductwork Replacement Cost in 2026?
Ductwork replacement cost is the total price to remove and reinstall the network of supply and return air ducts that carry heated and cooled air through a home. It typically ranges from $1,400 to $5,600, driven by the home’s size, the duct material chosen, and how easy the ducts are to reach.
Most homeowners pay about $3,000 for a full residential duct replacement in 2026. The table below shows typical price bands by home size and by project scope.
| Project scope | Typical 2026 cost | What it includes |
|---|---|---|
| Single duct run repair | $200 to $700 | Replacing or patching one damaged, disconnected, or crushed section |
| Partial replacement | $1,000 to $2,500 | Several runs plus new registers in one zone of the home |
| Full replacement (1,000 to 2,000 sq ft home) | $1,900 to $4,200 | All supply and return ducts, plenum, and connections |
| Full replacement (2,000 to 3,000 sq ft home) | $3,500 to $5,600 | Larger duct network, often two zones, more labor hours |
| Duct sealing (alternative) | $1,100 to $4,000 | Mastic or aerosol sealing of joints instead of replacement |
Priced another way, installed ductwork costs $25 to $55 per linear foot. A typical home needs 150 to 300 linear feet, which is where the average lands.
What Factors Affect Ductwork Replacement Cost?
Ductwork replacement cost factors are the specific conditions in a home that raise or lower the final quote, from the duct material to how accessible the runs are. Accessibility and total linear footage move the price the most, while material choice and added features like insulation or dampers adjust it further.
- Home size and linear footage: more square footage means more duct, at $25 to $55 per linear foot installed.
- Accessibility: ducts in an open basement cost less than ducts buried in a finished ceiling or tight crawl space.
- Material: flexible ducting is cheapest; insulated sheet-metal and rigid fiberboard cost more but last longer.
- Insulation and sealing: R-6 or R-8 insulated ducts add $1 to $3 per linear foot but cut energy loss.
- Removal and disposal: tearing out old, possibly asbestos-wrapped ducts adds labor and testing fees.
- Simultaneous HVAC work: replacing ducts during a furnace or AC swap can lower per-unit labor cost.
According to the U.S. Department of Energy, about 20% to 30% of the air moving through a typical duct system is lost to leaks, holes, and poor connections, which is why sizing and sealing matter as much as the ducts themselves.
Ductwork Repair vs Replacement: Which Do You Need?
Ductwork repair vs replacement is the decision between fixing isolated damage and installing an entirely new duct system. Repair makes sense for a few disconnected or crushed runs on an otherwise sound system, while replacement is the better value once leaks, corrosion, or undersized ducts appear throughout the home.
| Situation | Better choice | Typical cost |
|---|---|---|
| One or two disconnected runs | Repair | $200 to $700 |
| Widespread leaks, good duct material | Sealing | $1,100 to $4,000 |
| Ducts 15+ years old, rusted or moldy | Replacement | $1,900 to $5,600 |
| Rooms that never heat or cool evenly | Replacement or redesign | $2,500 to $5,600 |
If your energy bills are climbing and some rooms stay uncomfortable, ask an HVAC technician to run a duct-leakage test before committing to either path.
Does a Home Warranty Cover Ductwork Replacement?
Home warranty ductwork coverage is protection for the duct system when it fails from normal wear and tear, as part of a covered heating and air conditioning system. Empire Home Protect plans help cover duct repair and, where the plan allows, replacement of failed ducts, but not upgrades tied to remodeling, code changes, or pre-existing defects.
Coverage is provided under the contract, and a covered repair is carried out by an independent, licensed service technician. Standard exclusions across the industry usually include ductwork damaged by rodents, asbestos abatement, and improper prior installation. For the full breakdown of what qualifies, see our guide on whether a home warranty covers ductwork, and compare providers in our 2026 home warranty rankings.
How to Lower Your Ductwork Replacement Cost
Lowering ductwork replacement cost means using timing, comparison shopping, and coverage to reduce the out-of-pocket total. The steps below routinely save homeowners several hundred to a few thousand dollars on a full duct project.
- Get at least three itemized quotes and confirm each includes removal, disposal, and sealing.
- Ask whether sealing the existing ducts for $1,100 to $4,000 would solve the problem instead of full replacement.
- Bundle duct work with a scheduled furnace or AC replacement to share labor and crane or access costs.
- Schedule in spring or fall, when HVAC contractors are less booked and more likely to discount.
- Carry a home warranty so covered duct failures cost only a service fee, typically $75 to $125 per visit.
Frequently Asked Questions
How much does it cost to replace ductwork in a 2,000 square foot house?
Replacing ductwork in a 2,000 square foot house typically costs $3,500 to $5,600 in 2026. The figure covers all supply and return runs, the plenum, new registers, insulation, and labor. Homes with easy attic or basement access sit at the lower end, while finished ceilings and tight crawl spaces push the price higher.
Is it worth replacing old ductwork?
Replacing old ductwork is usually worth it once ducts are 15 or more years old and showing rust, mold, or widespread leaks. New, properly sealed ducts recover the 20% to 30% of conditioned air that leaky systems waste, lower monthly energy bills, and improve comfort. For minor issues, sealing at $1,100 to $4,000 is the more cost-effective fix.
Can you replace ductwork yourself?
Homeowners can replace short, accessible flexible-duct runs, but full ductwork replacement is not a recommended DIY project. Proper sizing, sealing, and balancing require load calculations and specialized tools, and mistakes reduce efficiency and can void HVAC warranties. Licensed HVAC contractors also handle asbestos-containing older ducts safely, which is a regulated hazard.
Does homeowners insurance cover ductwork replacement?
Homeowners insurance covers ductwork only when damage comes from a sudden covered peril, such as a fire or fallen tree. It does not pay for ducts that fail from age, wear, or leaks. A home warranty is the product designed for wear-based failures, helping cover repair or replacement for the cost of a service fee.
How long does ductwork last?
Well-installed ductwork lasts 20 to 25 years on average, though flexible ducting and systems in humid or pest-prone spaces may need attention sooner. Signs it is nearing the end include visible sagging, torn insulation, musty odors, and rooms that never reach the set temperature. Annual HVAC maintenance extends duct life.
