How Much Does Duct Repair & Sealing Cost in Irving, TX?

Our Duct Repair & Sealing services in Irving, TX typically run between $350 and $1,200 for a single-family home, depending on how much ductwork needs attention and how it’s accessed. Most Irving homeowners with a standard 1,800-2,400 sq ft home land somewhere between $450 and $750 when the damage is localized to a handful of runs. Whole-system aeroseal or mastic-seal jobs on older construction – common in Las Colinas and Valley Ranch neighborhoods built in the late 1980s through the 1990s – run $900 to $1,800 or more.

At CleanRun, every job starts with a written price before a single panel comes off – that’s Haven Standard Clause 1, and it applies to every job we’ve done since Tomas Reyes founded the company in 2013. No “call for a quote.” The number is on paper before the work begins.

Duct Repair & Sealing Cost Breakdown (2026)

The table below reflects real pricing for the Irving market in 2026. These are not national averages copied from an aggregator site. They reflect what Irving homeowners are actually paying based on the homes we work in – everything from 1960s slab-foundation houses near Irving Boulevard to newer construction in Coppell-adjacent ZIP codes.

What Pushes the Price Up

The single biggest cost driver in Irving isn’t the sealant material – it’s access. Homes in older Irving neighborhoods like Finley and Shady Grove often have ductwork running under the slab or through tight attic spaces that haven’t been touched since the original install. When a technician has to cut an access panel, work in a 110-degree attic in July, or trace a duct run that’s been buried under blown-in insulation, the labor time climbs. That’s normal. What’s not acceptable is finding that out after the job starts – which is why the written price has to come first.

Aeroseal, the pressurized polymer injection process, sits at the top of the price range for a reason: it seals leaks that no hand-applied mastic can reach, including micro-cracks in flex duct liners and small gaps at buried connections. For a home where the ducts run through a concrete slab – a configuration common in Irving construction from the 1960s through the early 1980s – Aeroseal is often the only real option. The upfront cost is higher, but so is the measurable result: before-and-after leakage rates are documented in the process itself.

What Brings the Price Down

Leakage that’s caught early, before the flex duct liner tears completely or the disconnected joint has been pulling unconditioned attic air for two summers, is cheaper to fix. A single disconnected run found during a routine Duct Repair & Sealing in Irving inspection might be a one-line repair at $85-$175. Waiting until three or four runs are affected – which is what typically happens when homeowners notice the problem through inconsistent room temperatures or a spike in their Oncor bill rather than through a scheduled inspection – turns a straightforward repair into a half-day mastic job.

What Affects Duct Repair & Sealing Pricing in Irving

• Home age and original duct material: Irving has a wide housing stock, from early 1960s construction near Story Road to 2010s builds in the Hackberry Creek area. Older homes typically have rigid sheet metal ducts that can be patched or re-sealed at joints; homes built from the 1980s through the 2000s predominantly use flex duct, which degrades differently – the inner liner tears, the outer jacket separates – and requires different repair methods. Sheet metal repair is generally more labor-intensive per section; flex duct replacement is faster but may involve more sections.
• Duct location – attic vs. slab vs. crawlspace: North Irving homes built on pier-and-beam foundations sometimes have ductwork running in a crawlspace, which is easier to access than slab-buried runs but still adds time. Attic ductwork in Texas heat requires technicians to work in conditions that slow progress and add safety margin to scheduling. Slab-buried ducts effectively require Aeroseal because hand-application simply isn’t physically possible.
• Extent of leakage – localized vs. system-wide: A pressure test (blower-door or duct pressurization) measures how much air the system is losing as a percentage of total airflow. A system losing 10-15% from one disconnected joint is a localized repair. A system losing 30%+ across dozens of small seam gaps is a whole-system job. Irving homes with original equipment from the 1990s often show system-wide leakage because the duct tape used at the time – yes, actual cloth duct tape – has fully dried out and pulled away from every joint it was ever applied to.
• Whether cleaning needs to happen first: Sealing a dirty duct system is the wrong order of operations – mastic applied over a debris-coated surface doesn’t bond properly, and Aeroseal requires clear duct walls to seal effectively. If the system hasn’t been cleaned recently, that step needs to happen before sealing begins. Most Irving homeowners scheduling a repair on a home they’ve owned for 5-plus years without prior service end up with a combined cleaning-and-sealing job. That’s a higher total cost, but it’s also the only way the seal holds.
• Number of supply and return runs: A 1,400 sq ft Irving home might have 8-10 supply runs and 1-2 return paths. A 2,800 sq ft two-story in Valley Ranch could have 18-22 runs across two systems. More runs mean more joints, more linear feet of flex duct, more potential failure points, and more labor time. Written pricing accounts for the actual count on the specific home – not a square-footage formula applied blindly.
• Permit requirements: The City of Irving requires a mechanical permit for new duct installation or major duct system replacement work. Repair and sealing of existing ductwork typically falls under maintenance and doesn’t require a pull, but a full system replacement – when repair is no longer viable – does. We tell every customer which category their job falls into before pricing it, because a job that requires a permit has additional cost and timeline that should be in the written scope.

How to Save on Duct Repair & Sealing in Irving

Get the Camera Inspection Before Agreeing to a Scope

The most common way Irving homeowners overpay for duct work is agreeing to a whole-system seal when only two or three runs actually need attention. The reverse also happens: agreeing to a patch on a system where the leakage is widespread, paying for a repair that buys 18 months of relief before the same symptoms come back. A proper camera inspection – the kind that actually puts the camera inside the run and documents what it finds – tells you what you’re actually dealing with before you sign anything. At CleanRun, that inspection cost ($125-$225) applies toward the repair when work proceeds. You’re not paying for it twice.

Combine Cleaning and Sealing When Both Are Needed

Scheduling cleaning and sealing as a single visit costs less than two separate appointments. If your ducts haven’t been cleaned in more than four years – which describes most Irving homes where the owners didn’t purchase the service as part of the original home inspection process – you’re likely looking at both services anyway. Doing them together means the technician is already positioned, the equipment is already on-site, and the written price reflects the combined scope rather than two separate mobilization charges.

Don’t Delay When You Notice the Early Signs

The warning signs of duct leakage in Irving homes are pretty consistent: one room that’s noticeably warmer than the others in July, a utility bill that climbed faster than your neighbors’ in the same Oncor rate period, or dust patterns around supply registers that don’t match the airflow you’d expect. Every month a disconnected run goes unfixed, conditioned air is being dumped into attic space – which in an Irving summer sits at 130-150 degrees – and the HVAC system runs longer to compensate, adding wear and operating cost simultaneously. A $150 single-run repair addressed in April doesn’t become a $650 multi-run job by August.

Use the Free Second Opinion

If a competitor has already given you a written estimate, bring it. CleanRun puts its own number next to it in writing – same scope, documented side by side. This applies to any written estimate, no exceptions, at no charge. In a market where $79 “whole-house duct cleaning” coupons are still circulating in Irving, the gap between what a coupon company charges after the upsell and what a written-price-first company charges from the start is often smaller than homeowners expect.

Call (682) 297-4068 for a Written Estimate

Every estimate is free. Every estimate is written before the truck moves. Call (682) 297-4068, describe the home – age, square footage, which ZIP code in Irving – and Tomas Reyes’s team will give you a realistic range before scheduling a visit, then a fixed written price when they arrive. Haven Standard Clause 1 means there’s no number on the invoice that wasn’t on the estimate.

Irving-Specific Duct Conditions Worth Knowing

Irving’s climate does specific things to ductwork that a generic national pricing guide won’t mention. The DFW metro’s combination of intense summer heat, occasional hard freezes (the February 2021 event exposed a lot of duct vulnerabilities that hadn’t been visible before), and soil movement from expansive clay means that duct connections in Irving homes move more than they do in stable-soil markets. Pier-and-beam homes near the Trinity River corridor in north Irving are particularly susceptible to flex duct disconnects at the boot connection as the structure settles seasonally.

In Las Colinas commercial-adjacent residential streets, we regularly find duct systems that were modified during renovation work without a mechanical permit – extra runs added, original returns partially blocked, insulation disturbed and not replaced. These systems look fine from the register but show significant leakage on a pressure test. The before-photo on a camera inspection in these homes often shows duct connections held together with original 1990s duct tape that has turned brittle and pulled away from the sheet metal by an inch or more.

Valley Ranch, built largely between 1985 and 1995, has a specific duct configuration pattern: supply runs dropping from an attic air handler through interior walls to floor-level registers. That routing puts a lot of flex duct in tight wall cavities where it can’t be visually inspected without opening the wall. Pressure testing is the only reliable way to find leakage in these runs. When the test shows significant loss and the camera can’t get to the source, Aeroseal is often the only practical repair.

The broader point: Irving pricing can’t be read off a national chart because Irving’s housing stock, soil, and climate create conditions that differ from what a Dallas high-rise condo or a Frisco new-build present. The numbers on this page reflect what we actually see in Irving homes – documented in job photos going back to 2013 across 52,000+ service visits.

Duct Repair vs. Duct Replacement: When Does It Make Sense to Start Over?

This question comes up in a specific subset of Irving homes, mostly those built before 1980 or those where a previous owner did significant renovation work without touching the HVAC system. The decision framework isn’t complicated, but it matters for pricing:

• Repair makes sense when the duct material is structurally sound, leakage is localized, and the system layout matches the current home’s room configuration. Most homes in Irving’s Heritage District and the neighborhoods around MacArthur Boulevard fall into this category.
• Replacement makes sense when flex duct liner is cracked along multiple runs (not just disconnected at joints), when the system layout was designed for a different floor plan, or when repair costs are projected to exceed 50-60% of replacement cost. At that point, the math and the long-term performance both favor starting fresh.
• Replacement cost context: Full duct system replacement for an Irving home typically runs $2,500-$6,000 depending on system size, number of runs, and whether the air handler location requires rerouting. This is a larger project that requires a mechanical permit from the City of Irving and should be quoted as a full written scope – not a verbal estimate.

We document the condition of every run with the camera inspection. When a system is on the line between repair and replacement, the customer sees the photos and the pressure test results before we give a recommendation. The recommendation comes with a written repair price and a written replacement price side by side. That’s the only honest way to present the choice.

The Documentation You Receive After Every Job

This section exists because “documented photo record” is a phrase that can mean almost anything in this industry. Here’s what it specifically means at CleanRun:

• Camera images from inside each duct run – before and after, labeled by location (supply run 3, return plenum, boot at master bedroom register, etc.)
• Written scope showing exactly which runs were repaired, what method was used, and what material was applied
• Pre-work and post-work pressure test results where testing was performed, showing the leakage rate before sealing and after
• The 365-Day Done Right Promise in writing – not a verbal assurance, a written document that specifies what we’ll do if the repair doesn’t hold

The before-photo practice started on CleanRun’s first job in 2013. It has never been optional on a CleanRun visit. When a homeowner in Irving’s Cottonhill neighborhood asks why one room is still warm after we sealed three runs, we can pull up the job record, show the post-seal pressure test, and either confirm the seal is holding (and the problem is elsewhere) or return to fix what didn’t hold – covered by the 365-Day Promise. That’s how a written guarantee functions differently from a verbal one.

FAQs: Duct Repair & Sealing Cost in Irving

How much does duct sealing cost for an average Irving home?

For a typical Irving single-family home in the 1,800-2,400 sq ft range, duct sealing runs $450-$950 depending on the method and how many runs need attention. Mastic sealing of a full system lands in the $550-$950 range. Aeroseal, which handles leaks that can’t be reached by hand application, runs $1,200-$1,800 for a full system. Partial sealing of two to four problem runs costs $250-$550. Call (682) 297-4068 for a written estimate specific to your home’s age and configuration – we’ll give you a real range before scheduling, not after arrival.

Is duct sealing worth the cost in Irving’s climate?

Yes, and the math is measurable. A system losing 25-30% of conditioned air to attic leakage – common in Irving homes with original 1990s flex duct – is forcing the HVAC unit to run significantly longer to meet thermostat demand. Oncor’s residential rates mean that extended run time adds up quickly across a Texas summer. Most whole-system sealing jobs in Irving show a 15-25% reduction in measured duct leakage, which translates to a shorter HVAC run cycle and lower monthly operating cost. The exact payback period depends on your current leakage rate, your system’s age, and your utility usage pattern. We can show you the before-and-after pressure test numbers so you’re not estimating it.

Can duct repair be done the same day in Irving?

Single-run repairs and localized mastic sealing are same-day jobs in most cases – typically 2-4 hours depending on access. Aeroseal requires the system to be cleaned first and the polymer to cure before the system goes back into operation, so that’s usually a full-day project. Whole-system mastic sealing on a larger home (2,800+ sq ft, 18+ runs) is also a full day. We schedule based on the scope confirmed during the written estimate, so there are no surprises about timeline any more than there are about price. Call (682) 297-4068 to discuss availability for your specific job.

Why is one company quoting me $200 and another $1,100 for the same Irving home?

The $200 quote is almost certainly a loss-leader to get a technician inside your home – common in the Dallas-Fort Worth market where $79 and $99 duct cleaning coupons are used to generate upsell opportunities once the crew is on-site. The $1,100 quote may reflect a full scope that the $200 company will eventually recommend after the initial visit, plus a margin for the upsell process. The way to compare accurately is to get both numbers in writing for the exact same scope of work. CleanRun offers a free second opinion on any written estimate – bring the competitor’s quote and we’ll put our number next to it on paper, same scope, no charge.

Does duct sealing require a permit in Irving?

Sealing and repairing existing ductwork in Irving generally does not require a mechanical permit – it falls under maintenance of an existing system. A full duct system replacement, or installation of new ductwork as part of an HVAC system change, does require a mechanical permit from the City of Irving’s Building Inspection Division. We identify which category your job falls into before pricing it, because a project that requires a permit has a different timeline and cost structure than a straight repair. If a permit is required for your scope of work, that information is in the written estimate before any work starts.

Key Takeaways

• Duct repair and sealing in Irving typically costs $350-$1,200 for most single-family homes; Aeroseal runs $1,200-$1,800 for whole-system pressurized sealing.
• Older Irving neighborhoods – Valley Ranch, Las Colinas residential areas, homes near Story Road and Heritage District – often have original flex duct or dried-out duct tape from the 1980s-90s that requires more than a patch.
• Irving’s clay soil and temperature extremes accelerate duct disconnects at joints and boots; annual inspection catches problems before they become multi-run jobs.
• Sealing a dirty system is wrong order of operations – cleaning must come first for mastic or Aeroseal to bond properly.
• Every CleanRun job includes a written price before work starts, a documented photo record of every run, and the 365-Day Done Right Promise in writing.
• The City of Irving requires a mechanical permit for new duct installation but generally not for repair and sealing of existing systems.
