Understanding Ductwork Installation Costs
The ductwork installation cost typically ranges from $2,000 to $5,000 for most homes, with a national average of about $3,000. Here's what you can expect to pay:
- Average cost per linear foot: $15-$40
- Small home (1,000-1,500 sq ft): $1,500-$3,000
- Medium home (2,000-3,000 sq ft): $2,800-$6,700
- Large home (3,500+ sq ft): $4,500-$9,000
Ductwork serves as the circulatory system of your home, delivering heated or cooled air throughout your living spaces. When considering ductwork installation cost, it's important to understand that several factors influence the final price tag.
The cost varies significantly based on your home's size, the materials you choose, and whether you're replacing existing ducts or installing a completely new system. Sheet metal ducts cost more upfront ($7-$13 per linear foot) but last 20+ years, while flexible ducts are more affordable ($1-$3 per linear foot) with a shorter 10-15 year lifespan.
Location matters too. Installing ducts in accessible areas like unfinished basements costs less than working in cramped attics or finished walls that require repairs afterward. Labor typically accounts for 60-70% of your total ductwork installation cost, with rates ranging from $70-$90 per hour in most regions.

What Is Ductwork and Why It Matters
Ductwork is the network of tubes that runs throughout your home, connecting your heating and cooling system to each room. Think of it as your home's respiratory system—when it works properly, you barely notice it's there. When it doesn't, everyone feels the difference.
Your home's ductwork does so much more than just move air around. When properly designed and installed, it creates a comfortable living environment by maintaining consistent temperatures throughout your home. Good ductwork quietly filters out dust, allergens, and other airborne particles that could affect your family's health. It also helps control humidity levels, making your home feel just right regardless of the season.
Perhaps most importantly for your wallet, efficient ductwork dramatically improves your home's energy efficiency. According to ENERGY STAR, leaky or poorly installed ducts can reduce your HVAC system's efficiency by up to 20%. That's essentially throwing away $20 of every $100 you spend on heating and cooling! When calculating ductwork installation cost, quality installation often pays for itself through these energy savings.
Here in Western Pennsylvania, southeastern Ohio, and northern West Virginia, our dramatic temperature swings make efficient ductwork particularly important. Our customers in Pittsburgh, Washington PA, and Steubenville OH frequently tell us about the noticeable comfort improvements and lower utility bills they enjoy after professional duct installation.

Key Functions of a Well-Designed Duct System
A well-designed duct system carefully balances two critical airflow paths that work together like a circulatory system. Supply ducts deliver freshly conditioned air to your rooms, while return ducts pull air back to your HVAC system for reconditioning. This creates a continuous loop that maintains proper static pressure throughout your home.
Without adequate return air, your system works much harder than it should. Rooms become stuffy or drafty, and your ductwork installation cost doesn't deliver its full value. I've visited homes where return air was an afterthought, and the difference proper balancing makes is remarkable.
Proper duct sizing is equally crucial. Ducts that are too small create annoying whistling noises and restrict airflow, while oversized ducts waste energy and money. At Smart Climate Solutions, our technicians use industry-standard Manual D calculations to ensure your ducts are perfectly sized for your specific home and HVAC equipment. It's this attention to detail that makes all the difference in your comfort.
Typical Lifespan of Different Duct Types
When budgeting for ductwork installation cost, consider how long your investment will last with different materials:
Flexible ducts typically last 10-15 years and come with a lower upfront cost. They're perfect for navigating tight crawlspaces but are more vulnerable to sagging, crushing, and tearing over time. Fiberboard ducts offer a middle-ground option with a 15-20 year lifespan and decent insulation properties. Sheet metal ducts represent the premium choice, lasting 20-25+ years with proper maintenance. They cost more initially but often provide better long-term value due to their durability.
In my 15+ years serving homes across South Hills PA, Burgettstown PA, and Weirton WV, I've seen properly installed sheet metal ductwork maintain excellent efficiency for decades. Many homeowners find the higher initial ductwork installation cost worthwhile when they consider the extended lifespan and reduced maintenance needs. That said, we work with all budgets and can recommend the best solution for your specific situation.
Average Ductwork Installation Cost in 2025
The national average ductwork installation cost in 2025 ranges from $2,000 to $5,000 for most homes. But what will it actually cost you? Let's break down the numbers in a way that makes sense for your budget planning.
When I talk with homeowners about ductwork, the first question is almost always about cost. If you're replacing existing ductwork, you're typically looking at $1,400-$5,600. For completely new ductwork in an existing home (much more labor-intensive), expect $5,000-$15,000+. The silver lining for new construction? You'll generally save about 10-15% compared to retrofit installations.
Where you live matters too. In our Western Pennsylvania service area, Pittsburgh metro homeowners typically pay slightly above the national average. If you're in a rural area like Burgettstown PA, you might save 5-10% compared to city rates. And those beautiful older homes in St. Clairsville OH? They often need custom ductwork solutions, which can bump up your costs.
Let's talk materials – they make a huge difference in both performance and price:
| Material Type | Cost Per Linear Foot | Pros | Cons |
|---|---|---|---|
| Flexible Non-Insulated | $1-$3 | Affordable, easy to install | Shortest lifespan, less efficient |
| Flexible Insulated | $2-$4 | Better energy efficiency, good for tight spaces | Can sag, 10-15 year lifespan |
| Fiberglass Duct Board | $4-$6 | Good insulation, noise reduction | Harder to clean, 15-20 year lifespan |
| Sheet Metal | $7-$13 | Longest lifespan (20+ years), most durable | Higher upfront cost, requires more skill to install |
| Spiral Metal | $9-$37 | Excellent airflow, durable, can be exposed | Most expensive option |
Here's something worth considering: the Department of Energy found that properly sealed and insulated ducts can improve your HVAC efficiency by up to 20%. That means your higher upfront ductwork installation cost could actually save you money month after month on your energy bills. You can learn more about these savings from ENERGY STAR's research on duct sealing benefits.
Cost per Linear Foot: ductwork installation cost breakdown
When I'm helping families budget for new ductwork, I break down the ductwork installation cost into materials and labor. For materials, flexible non-insulated ducts run $1-$3 per linear foot, while premium sheet metal ducts cost $7-$13 per linear foot.
Labor is where things get interesting. A straightforward installation in an open basement might cost just $5-$8 per linear foot. But if we're working in your cramped attic on a hot summer day? That's more challenging work at $10-$18 per linear foot. And retrofitting ductwork into finished spaces with minimal damage to your walls? That specialized work runs $12-$20+ per linear foot.
Don't forget the extras! Each vent cover or register adds $15-$50, dampers (which help balance airflow) cost $30-$150 each, and proper insulation adds $1-$8 per square foot of duct surface.
For perspective, a typical 2,500 square foot home needs about 250-300 linear feet of ductwork. When you add everything up, that's why the total ductwork installation cost typically lands between $6,250 and $16,500.
Many of our customers in Washington PA and Steubenville OH find that insulated flexible ducts hit the sweet spot of affordability and performance. They're not the cheapest option, but they deliver excellent value without breaking the bank.
Cost by Home Size & Layout
Your home's unique characteristics play a huge role in determining your final ductwork installation cost. The square footage tells part of the story:
A cozy 1,000-1,500 sq ft home typically needs around 150 linear feet of ductwork, costing $1,500-$3,000. Medium-sized homes (2,000-2,500 sq ft) generally require about 250 linear feet, bringing costs to $3,000-$6,000. Larger 3,000-3,500 sq ft homes need approximately 350 linear feet at $4,500-$8,000, while homes over 4,000 sq ft can expect 400+ linear feet of ductwork at $6,000-$9,000+.
But here's what many contractors won't tell you – the layout often matters more than raw square footage. In my 15+ years of experience across Southwestern PA, I've seen compact two-story homes in Weirton WV need significantly less ductwork than sprawling ranch-style homes with the same square footage in rural Washington PA.
Ranch-style homes typically need more linear feet of ductwork since rooms are spread out horizontally. Multi-story homes might need less total ductwork but present vertical challenges that require more complex installation techniques. And those charming split-level homes? They often need creative solutions to maintain balanced airflow between different levels.
The good news? When you work with experienced professionals who understand these nuances, we can often find ways to optimize your system design and potentially save you money while still delivering the comfort you deserve. For more detailed information about factors affecting costs in your specific area, check out our guide on Duct Installation Cost.
Factors That Drive Your Final Price Tag
Let's talk about what really affects your ductwork installation cost – because understanding these factors helps you budget smarter and avoid surprises. I've seen countless homeowners in Pittsburgh caught off-guard by costs they didn't anticipate.
Material Choices & Lifespan Impact
The ductwork material you select dramatically impacts both what you'll pay now and over time:
Rigid Sheet Metal (Galvanized Steel) costs $7-$13 per linear foot and typically lasts 20+ years. It's like buying a quality cast iron pan – more expensive upfront but practically heirloom-worthy in durability. These ducts maintain excellent airflow throughout their long life, though they do require more skilled installation.
Spiral Metal Ducts run $9-$37 per linear foot and offer superior airflow. Some of our South Hills customers actually leave these exposed as architectural features – they look that good! The downside? They're the premium option price-wise and require specialized installation techniques.
Flexible Insulated Ducts are the budget-friendly option at $2-$4 per linear foot. They're the ductwork equivalent of a decent pair of sneakers – affordable and perfectly functional, but you'll be replacing them sooner (10-15 years). They're fantastic for squeezing through tight spaces, but can sag over time if not properly supported.
PVC Ducts fall in the middle at $3-$5 per linear foot. They shine in moisture-prone areas but aren't suitable for all systems. Think of them as specialty players – great for certain situations but not your go-to for the whole home.
For most of our Western Pennsylvania homes, we typically recommend a hybrid approach – durable sheet metal for main trunk lines with flexible ducts for branches. This balances cost and longevity beautifully.
Labor & Accessibility Considerations
Labor typically makes up 60-70% of your total ductwork installation cost, and where your ducts need to go matters tremendously:
Installing in an attic ($2,200-$5,600) means our technicians are working in potentially sweltering conditions with limited headroom. I've personally lost 5 pounds in sweat installing ducts in Pittsburgh attics during August!
Basement installations ($1,800-$4,200) are generally more straightforward but often involve navigating around water heaters, plumbing, and electrical systems – especially in older Steubenville homes.
Crawlspace work ($3,000-$7,300) is particularly challenging. Our technicians sometimes spend hours on their stomachs in spaces barely 24 inches high. The tight conditions slow everything down and may require specialized equipment.
When we need to install ductwork in finished walls and ceilings ($4,000-$8,000+), costs climb quickly. We're essentially performing surgery on your home – carefully opening walls, installing ducts, then patching everything back up.
Our technicians typically charge $70-$90 hourly, with projects ranging from 1-2 days for simple basement replacements to 5+ days for complex whole-home installations in finished spaces.

Add-On Services & Hidden Fees
When budgeting for your ductwork installation cost, keep these potential extras in mind:
Permits ($250-$1,500) are required throughout most of our service area. Washington PA tends toward the lower end of this range, while Pittsburgh proper is typically higher.
Adding new vents or registers ($200-$350 each) can dramatically improve comfort in previously underserved rooms. I've seen homeowners transformed from skeptics to believers after we added a single strategically placed vent in their home office.
Duct sealing ($330-$1,500) isn't optional if you want maximum efficiency. Think of unsealed ducts like trying to inflate a balloon with holes in it – you're paying to heat or cool air that never reaches your living spaces. Proper sealing can reduce this waste by up to 20%.
Insulation ($800-$2,000) becomes critical for ducts running through unconditioned spaces. Without it, you'll lose significant heating and cooling power before the air even reaches your rooms.
In older homes throughout Western Pennsylvania, we sometimes encounter asbestos (testing/removal up to $2,900) or mold issues ($500-$6,000). These aren't just cost concerns but health considerations that can't be ignored.
At Smart Climate Solutions, we pride ourselves on transparent pricing. We'll walk through your home, identify all potential costs, and provide a detailed, itemized quote before any work begins. No one likes financial surprises, especially when it comes to essential home improvements.
Ways to Save Money Without Sacrificing Comfort
Looking to manage your ductwork installation cost without compromising quality? I've seen countless homeowners throughout Western Pennsylvania, southeastern Ohio, and northern West Virginia successfully use these strategies to save money while still getting excellent results.
Consider partial replacement rather than a complete system overhaul. Many times, only certain sections of your ductwork are problematic. By replacing just those troublesome portions, you can save 40-60% compared to a full replacement. Last month, we helped a family in Washington PA save over $2,000 by focusing only on the damaged sections in their basement.
Always get multiple quotes from reputable contractors. Even though we're confident in our pricing at Smart Climate Solutions, we encourage homeowners to compare 3-4 estimates. Just make sure you're comparing equivalent scopes of work – sometimes the cheapest quote is missing crucial elements that you'll end up paying for later.
Timing matters too. Scheduling during off-peak seasons like spring and fall can save you 10-15% when demand is lower. Many of our Pittsburgh customers have taken advantage of our April and October specials to reduce their ductwork installation cost.
Smart homeowners often bundle projects together. If you're already upgrading your furnace or air conditioner, adding ductwork improvements at the same time typically results in package discounts of 5-10%. Plus, you'll only have to deal with one installation period rather than multiple disruptions.
Don't underestimate the value of maintenance. Proper care of your existing ductwork through regular cleaning and sealing can extend its life, postponing the need for replacement. Some of our customers in Steubenville OH have added years to their systems with simple preventative maintenance.
For the DIY-inclined, sealing accessible ducts yourself can save money. While we recommend professional installation for the main system, homeowners can often seal visible duct connections in basements or attics using UL-listed aluminum tape (not regular duct tape!) or mastic sealant. Just be sure to follow proper techniques.
Don't forget to check for utility rebates and incentives. Many energy companies throughout our service area offer rebates for duct sealing and insulation improvements. We recently helped a family in South Hills PA secure a $500 rebate on their ductwork project – money that would have otherwise been left on the table.
Being strategic about materials can also reduce your ductwork installation cost. Choose the right material for each application – use premium materials for main trunk lines where durability matters most, and more economical options for less critical runs. Similarly, opt for insulated flexible ducts in unconditioned spaces like attics and crawlspaces. The slightly higher material cost pays for itself through energy savings, often within the first year.
Finally, ensure your system is properly sized. Right-sized ductwork performs better and costs less than oversized systems. Our technicians use industry-standard Manual D calculations to determine the exact duct dimensions needed for your home, avoiding the common and costly mistake of oversizing.
At Smart Climate Solutions, we work with customers throughout Southwestern PA to find the right balance between upfront ductwork installation cost and long-term performance. Our goal is always to provide maximum comfort and efficiency at a fair price – no unnecessary upsells, just honest recommendations based on what your home actually needs.

When to Repair, Replace, or DIY?
Deciding whether to repair, replace, or roll up your sleeves for a DIY ductwork project isn't always straightforward. As someone who's seen thousands of duct systems throughout Western Pennsylvania, I can tell you that making the right choice now can save you significant headaches (and dollars) down the road.
Signs Your Ducts Need Attention and ductwork installation cost implications
Your ductwork might not be as vocal as a squeaky door, but it definitely sends signals when something's wrong. Here's what to watch for:
Your ducts are likely crying out for help if you notice uneven temperatures throughout your home – those frustrating hot and cold spots that make some rooms feel like the Sahara while others remind you of winter in Pittsburgh. Rising energy bills without explanation (especially jumps of 15% or more) often point directly to duct issues, as your system works overtime trying to compensate for air that never reaches its destination.
Excessive dust collecting on surfaces shortly after cleaning might mean your ducts are pulling in debris from wall cavities or attic spaces. And those strange noises – the whistling, rattling, or popping sounds when your system kicks on? That's not your house settling; it's your ductwork talking to you.
When your HVAC runs and suddenly your home smells musty or moldy, your ducts might be harboring unwanted moisture. And of course, any visible damage like crushed sections, disconnections, or evidence of pests making themselves at home in your ductwork demands immediate attention.
Age is another crucial factor. Ducts over 15 years old typically develop deteriorating seals and insulation issues that compromise efficiency. According to Department of Energy research, homes with leaky ducts can lose up to 30% of conditioned air before it reaches living spaces – that's like throwing away nearly a third of your heating and cooling dollars!
For our customers in Pittsburgh, Washington PA, and throughout our service region, addressing these warning signs promptly almost always proves more economical than continuing to operate an inefficient system.

DIY vs Professional: Weighing Safety and ductwork installation cost
I've seen the temptation – that YouTube video makes ductwork look so simple, and the ductwork installation cost quoted by professionals seems high. But before grabbing your tools, consider what's really involved.
DIY ductwork requires specialized equipment most homeowners don't have: metal crimpers, aviation snips, sealing equipment, and more. Beyond tools, there's technical knowledge about load calculations, static pressure, and airflow dynamics that takes professionals years to master. One miscalculation can lead to a system that never performs correctly.
Safety concerns shouldn't be underestimated either. Many duct systems run through confined spaces with limited ventilation, and older homes in our service area often contain asbestos insulation around existing ductwork – not something you want to disturb without proper training and equipment.
Then there's the matter of code compliance. Most localities throughout Western Pennsylvania, southeastern Ohio, and northern West Virginia require permits and inspections for HVAC modifications. DIY work that doesn't meet code can cause problems when selling your home or with insurance claims. And let's not forget that most HVAC equipment warranties become void when connected to non-professionally installed ductwork.
Professional installation brings significant advantages that often justify the ductwork installation cost. Licensed contractors ensure all work meets building codes and provide warranties on their work (typically 1-10 years). They use proper Manual D calculations to ensure optimal airflow throughout your home, and their experience helps prevent common problems before they occur.
In my 15+ years helping homeowners throughout our region, I've unfortunately seen many DIY ductwork projects that ultimately cost more to fix than professional installation would have cost initially. That said, simple repairs like sealing accessible duct connections or replacing a short section of flexible duct are often within reach of a handy homeowner.
The bottom line? For system design, main trunk installation, or anything involving gas or electrical connections, professional installation almost always proves more cost-effective in the long run, even with the higher initial ductwork installation cost.
Frequently Asked Questions about Ductwork Installation Cost
How long does a full duct replacement take?
When homeowners ask me about timing, I tell them that most full ductwork replacements take between 1-4 days. It's a bit like asking "how long does it take to paint a house?" – the answer depends on the size!
For cozy homes around 1,000-1,500 square feet, we can usually wrap things up in just 1-2 days. Medium-sized homes between 2,000-3,000 square feet typically need 2-3 days for complete replacement. If you've got a larger home over 3,500 square feet, we generally need 3-4 days or sometimes longer.
But square footage isn't the only factor affecting your timeline. Accessibility makes a huge difference. A straightforward replacement in an open basement might be finished in just a day, while navigating a cramped attic or working within finished walls (where we need to be extra careful) can add significant time to the project.
Most of our customers in Pittsburgh, South Hills PA, and Steubenville OH see their projects completed within 2-3 days – just enough time to make weekend plans while we handle the work!
Can I replace only part of my ductwork?
Absolutely! Partial replacement is often the smartest way to manage your ductwork installation cost while still solving specific problems. Think of it like replacing a section of fence rather than rebuilding the entire perimeter.
Partial replacement makes perfect sense in several situations:
- When only certain sections show damage while others remain in good condition
- If you're mainly concerned about ducts in unconditioned spaces like attics or crawlspaces
- During renovations or room additions that require new airflow
- When upgrading main trunk lines while the branch ducts are still performing well
The best part? Partial replacements typically cost 40-60% less than completely overhauling your entire system. Our technicians at Smart Climate Solutions can assess your specific situation and recommend the most cost-effective approach, whether you're in Washington PA or anywhere throughout Southwestern Pennsylvania.
Does new ductwork boost home resale value or efficiency?
New ductwork definitely increases both your home's market appeal and its energy performance – it's one of those rare improvements that pays you back in multiple ways.
From a resale perspective, updated ductwork makes your home more attractive to potential buyers. Home inspectors frequently flag old or damaged ductwork, which can become negotiation points during sales. Energy-efficient homes typically command 2-5% higher prices in today's market, and updated HVAC systems (including proper ductwork) are significant selling points that buyers specifically look for.
The efficiency improvements are even more immediate. New, properly sealed ductwork can reduce energy waste by 20-30% – that's money back in your pocket every month! Modern insulated ducts minimize temperature loss in unconditioned spaces, and properly sized new ductwork helps your entire HVAC system perform at its best.
This is especially valuable for our customers throughout Western Pennsylvania, southeastern Ohio, and northern West Virginia, where we experience everything from sweltering summers to frigid winters. Many homeowners in Washington PA and Weirton WV tell us they notice dramatically improved comfort and significantly lower utility bills after upgrading their ductwork – sometimes within the very first month.
Conclusion
Let's face it—diving into ductwork installation cost research isn't exactly how most of us would choose to spend a Saturday afternoon. But as you've seen, understanding these costs can make a world of difference for both your comfort and your wallet.
While most homeowners can expect to pay between $2,000 and $5,000, your particular situation might look quite different. Your 1920s Craftsman in Pittsburgh will have different needs than a 1990s split-level in Steubenville, and that's exactly why cookie-cutter pricing rarely works for ductwork.
