This article was created using automation technology and thoroughly fact-checked and edited by an Angi Editor in accordance with our AI policy.

The cost to install ductwork averages $4,000, with a range from $2,000 to $12,000 depending on your home’s size and layout. Homeowners can expect to pay $10 to $25 per linear foot for new ductwork installation, including both materials and labor. Larger or more complex homes may see higher costs. This guide will help you understand every factor that affects the cost to install ductwork and how to plan for your project.

Cost by Size of Ductwork

The size of your home and the total length of ductwork needed are two of the biggest factors in determining installation cost. More square footage, extra stories, and additional rooms or zones all require more ducting, increasing both material and labor costs. 

New construction projects often have more straightforward installations, while retrofits in existing homes can be more complex and costly due to access issues and the need to work around existing structures.

Adding rooms or creating new zones increases the total required length, which can increase costs. In new builds, ductwork can be planned for efficiency, which reduces labor and material costs. Retrofitting an older or multi-story home with new ductwork often requires more labor and creative routing, which adds to the total price.

Ductwork Cost by Type

Choosing the right ductwork material is a key decision for both cost and performance. The most common types are sheet metal, flexible duct, fiberglass, and fiberboard. Each serves different purposes—sheet metal for main trunks, flexible duct for tight spaces, and specialized materials for unique needs. Durability, efficiency, and duct lifespan vary between materials, so weighing pros and cons is important.

Sheet metal ductwork is the most durable and efficient, but it comes at a higher initial cost and requires skilled installation. Flexible duct is less expensive and easier to install, especially in tight spaces, but it is less robust and may not last as long. Fiberglass-lined and fiberboard ducts offer additional insulation or affordability but may not be suitable for all applications.

Material choice also affects labor costs. Rigid sheet metal takes more time and skill to install, increasing labor charges, while flexible ducting can be installed faster, lowering labor costs. Energy efficiency over time also varies; investing in higher-quality ductwork can save money on utility bills in the long run.

Ductwork Cost by Location

Where you live and where the ductwork is being installed in your home can have a major impact on project costs. Labor and material prices are higher in urban areas compared to rural locations. Regional climate also plays a role, as colder areas may require additional insulation or specialized materials to prevent heat loss.

Within your home, the installation area also matters. Ductwork in attics and crawl spaces costs more due to restricted access and the need for extra insulation or equipment. Multi-story and historic homes can present additional challenges, such as navigating tight spaces or preserving architectural features, which increases labor costs and time.

Ductwork Installation Cost Factors

Several factors can influence the final price tag for ductwork installation. Understanding these details helps you budget more accurately.

Labor

Labor is a significant portion of the total cost to install ductwork. HVAC contractors and ductwork specialists charge $50 to $150 per hour. Small projects may carry minimum service fees, which can be significant for minor repairs or short runs. Labor may also be charged per linear foot, especially for larger jobs—expect to pay $5 to $15 per linear foot for labor alone. 

Regional differences can swing prices higher in metropolitan areas or where skilled labor is in high demand. The complexity of your project, such as the need to work around existing wiring or plumbing, will also increase labor hours and costs.

Permits

Most municipalities require permits for new installations or major modifications to existing ductwork systems. Permit fees range from $50 to $300 depending on location. Some areas require one or more inspections, which may add to the final bill if re-inspections are needed. Not securing the proper permits can result in fines, delays, and problems with future home sales or insurance claims.

Additional Features

You have the option to include upgrades that improve comfort, efficiency, or air quality:

• Adding HVAC zoning systems or smart dampers allows for better temperature control in different parts of your home. 

• Insulated ductwork, soundproofing, and vibration reduction features can enhance efficiency and comfort but come at an added cost. 

• Integrating purification or advanced air filtration systems costs more but can pay off with better health and cleaner air.

Installation Add-Ons

Several other items can affect the total cost to install ductwork in your home, including:

• Complexity of Installation: Multi-story homes, tight spaces, or unusual layouts require more labor and planning, which increases costs. Retrofitting ductwork in an existing home is more challenging than new construction, especially when working around plumbing, wiring, or structural elements.

• Accessibility: Ductwork in crawl spaces, attics, or other hard-to-reach areas requires extra effort and equipment, which increases labor costs.

• Site Preparation: Removing old ductwork, delivering materials, or addressing issues like mold or asbestos will add to your project costs.

• Post-Construction Cleanup: Debris removal and duct cleaning after installation ensure your system is safe and efficient.

• Design Fees: Custom ductwork design or HVAC system planning may involve consulting fees, especially for optimizing airflow or energy efficiency.

• Inspection Costs: Third-party inspections to verify code compliance or system balancing may be required, with additional fees if the work does not pass the first time.

Additional Costs to Consider

Along with material and labor costs, there are several additional costs to keep in mind when installing ductwork.

Warranties

Ductwork installations often come with manufacturer warranties on materials and workmanship warranties from contractors, covering one to ten years. Extended warranty options may be available for an added fee, offering peace of mind but increasing the initial investment. Carefully review what is covered, as labor and materials may have different warranty terms.

Operating Costs

New ductwork can lower your heating and cooling bills by improving efficiency, but adding new HVAC zones or advanced features may increase energy use. Overall, well-designed ductwork often leads to long-term savings. Consider the ongoing costs of maintaining additional equipment or features.

Maintenance

Routine maintenance is essential for keeping your ductwork efficient and problem-free. Plan to have ducts inspected and cleaned every three to five years, with average duct cleaning costs ranging from $300 to $700. Investing in duct sealing and checking for wear can prevent costly repairs and help your system last longer.

Taxes

Sales tax on materials and labor may apply depending on your location. Some energy-efficient ductwork upgrades could qualify for tax credits or rebates, helping offset installation costs. Check local and federal programs for eligibility.

Insurance

Most homeowner’s insurance policies cover ductwork damage from covered events, but not from normal wear and tear. Contractors should carry liability insurance and provide proof before starting work. For high-value or complex projects, consider additional coverage to protect your investment.

DIY Ductwork Installation vs. Hiring a Pro

Some homeowners consider installing ductwork themselves to save money, but this approach comes with risks. DIY costs include materials, tools, and possibly equipment rentals, often totaling $1,000 to $3,000 for small projects. Labor savings can be significant, but mistakes can lead to costly problems down the road.

Professional installation costs more but ensures your system meets code and functions safely. Skilled installers have the knowledge and tools to avoid common pitfalls, such as improper sealing or poor airflow, which can reduce efficiency and create safety hazards.

DIY installation requires basic HVAC knowledge, tools like tin snips, crimpers, and sealant, and a willingness to spend several days on the job. Even small projects can be time-consuming and physically demanding. For complex layouts, multi-story homes, or projects requiring permits, it’s best to hire a local duct installer.

Ductwork Replacement vs. Repair

Deciding between repairing and replacing ductwork depends on the age, condition, and performance of your system. Minor leaks or loose connections can often be repaired, especially if the ductwork is less than 15 years old and in otherwise good shape. Extensive rust, multiple leaks, or ducts over 20 years old often warrant full replacement for better efficiency and air quality.

Repair costs for minor issues range from $300 to $1,000, while complete air duct replacement costs $2,000 to $7,500 or more, depending on the scope. If duct repair costs approach half the price of new ductwork, replacement is the smarter long-term investment.

New ductwork improves energy efficiency, home comfort, and indoor air quality, making it a worthwhile upgrade if your current system is aging or underperforming.

Does Ductwork Add Value to Your Home?

Investing in new ductwork can offer a solid return on investment. Homeowners often see an ROI of 50% to 70% with improved energy efficiency, lower utility bills, and better home comfort. New ductwork can also increase buyer appeal, especially when paired with modern HVAC systems.

Safety improvements, energy efficiency, and improved air quality all add value. Universal design and accessibility features, as well as aesthetic considerations like hidden ductwork, can further boost home value and make your property more attractive to buyers.
