Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Repair & Sealing Across Arlington Heights
Most Arlington Heights duct systems were never designed for the air conditioning they now carry. We see it on nearly every job: original 1950s-70s galvanized trunk lines that dead-end at flex-to-metal junctions added during A/C retrofits, leaking conditioned air into wall cavities and pulling attic dust back into supply lines. Our Duct Repair & Sealing crews work these configurations daily. Dispatch and scheduling run from our Chicago office, and we route Arlington Heights calls to technicians who know the difference between a heat-era ranch on Kennicott Avenue and a retrofitted split-level near Thomas Middle School. Call (224) 344-8881 for a written estimate before any work starts.
Why CleanRun Air Duct Cleaning Elk Grove Village Is Arlington Heights’s Preferred Duct Repair & Sealing Company
We’ve documented the inside of over 52,000 homes since 2013, and Arlington Heights represents one of the highest concentrations of retrofitted duct systems in our service area. Homeowners here find us because they’ve already had a “cleaning” that didn’t change their airflow, or they’ve watched their energy bills climb while upstairs registers barely move air. Our reviews from Arlington Heights customers consistently cite the photo record: they see the junction that was missed, the seam that was leaking, the before and after on their own duct runs.
Response time to Arlington Heights neighborhoods - from downtown to the Scarsdale and Hasbrook areas - is typically same-week for standard appointments, with scheduling confirmed by a live person on every call. Technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. License number is published below; we don’t bury credentials in footers.
The local knowledge that matters here isn’t generic suburb familiarity. It’s recognizing that a 1965 split-level on Douglas Avenue likely has its main trunk line running through an interior wall cavity with 4-inch register boots that won’t accept modern cleaning tools without modification. Our crews carry the adapters and the patience for that work.
Our Duct Repair & Sealing Services in Arlington Heights
Duct Sealing
Arlington Heights’s extreme seasonal swing - Lake Michigan humidity in July, forced-air dryness in January - cycles old mastic and duct tape through expansion and contraction until leaks reopen at supply and return joints. We seal with mastic compound rated for the temperature range these systems see, not foil tape that’ll peel in two seasons. Every sealed joint is photographed before and after, and the photo record is delivered as part of the standard job documentation.
Flex Duct Repair
The flex spurs added to Arlington Heights trunk lines during 1970s-80s A/C retrofits are now 40-50 years old. Insulation sags, inner liners tear at bends, and the clamps at flex-to-metal junctions work loose. We replace damaged flex runs with new R-8 insulated duct, properly supported to prevent sagging, and seal the junction with mastic under Haven Standard Clause 1’s written pricing. A typical flex duct repair in Arlington Heights runs $280-$520 depending on run length and access.
Metal Duct Repair
Original galvanized trunk lines in Arlington Heights ranch and split-level homes rust from the inside where decades of condensation have pooled in low spots. We patch or replace corroded sections, re-seam separations at takeoffs, and reinforce areas where the metal has fatigued from vibration. Metal duct repair in Arlington Heights typically ranges $340-$680 for accessible trunk sections; slab-embedded or cavity runs requiring access modification are quoted individually in writing before work begins.
Duct Insulation
Unconditioned attic and crawl space runs in older Arlington Heights homes lose significant efficiency through bare or degraded insulation. We install new wrap or replace insulated flex where the vapor barrier has failed, particularly critical at flex-to-metal junctions that were never originally insulated. Proper insulation here prevents condensation that feeds mold and dust-mite debris in this climate.
Mastic Sealant Application
Mastic is the only sealant we use on Arlington Heights’s older metal ductwork. Unlike tape, it remains flexible across temperature cycles and fills irregular gaps at riveted seams and takeoff connections. We brush or trowel mastic to a minimum 1/16-inch thickness at every leak point, then photograph the application for the job record.

Our equipment roster includes Nikro negative-pressure extractors, Honeywell media air cleaners, and Aprilaire humidifier and filtration components - brands customers can research independently before agreeing to any scope of work. We stock common repair parts for Arlington Heights’s most prevalent system configurations, including flex duct adapters and mastic compounds rated for the temperature swings these homes experience. Turnaround on standard repairs is typically single-visit; we don’t return for parts we should have carried.
Common Duct Repair & Sealing Problems We See in Arlington Heights Homes
- Flex-to-metal junctions acting as debris dams. The clamped connection where a 1980s flex spur meets a 1960s galvanized trunk line was rarely sealed properly and is almost never accessible to standard cleaning tools. Debris accumulates for decades. Homeowners call us after a “cleaning” elsewhere because their airflow never improved.
- Original galvanized trunk lines in inaccessible locations. Ductwork running through interior wall cavities or beneath concrete slabs - common in Arlington Heights ranches - limits tool access and allows rust scale and construction debris to accumulate undisturbed since the home was built.
- Failed original sealants from seasonal cycling. The Chicago metro’s humidity extremes degrade old duct tape and mastic at joints, reopening leaks that pull unconditioned attic or crawl space air into the system while pushing heated or cooled air into spaces that don’t need it.
- Undersized returns on heat-only systems. Original duct designs for heating only didn’t anticipate the airflow demands of central A/C. We frequently find return trunks that are 25-30% smaller than modern code would require, forcing the blower motor to overwork and shortening equipment life.
Pricing for Duct Repair & Sealing in Arlington Heights, IL
We publish ranges because Haven Standard Clause 1 requires a written price before any work starts, every time. A typical duct sealing job in Arlington Heights - mastic application at accessible joints, flex-to-metal junction repair, and basic leak testing - runs $380-$720 for a single-system home. Flex duct replacement ranges $280-$520 per run. Metal duct repair on accessible trunk lines: $340-$680. Full-system sealing with blower-door-verified results: $890-$1,400.
What moves a job toward the higher end: slab-embedded ductwork requiring access creation, multiple flex-to-metal junctions needing replacement, or corroded metal requiring section replacement rather than patch. What we don’t do: quote a low arrival fee, then discover “additional problems” once the van is in your driveway. The price we write is the price you pay. Bring a competitor’s written estimate; we provide a free second opinion with our number next to theirs.
Every job includes the Documented Photo Record: inside every duct run we access, before and after, delivered as part of your standard job documentation. Call (224) 344-8881 for a written estimate - estimates are free.

FAQs - Duct Repair & Sealing in Arlington Heights
Arlington Heights’s dominant 1950s-70s housing stock was built for heat-only systems and later retrofitted with flex duct spurs for air conditioning, creating mismatched junctions that were rarely sealed properly and have now cycled through 40-50 years of seasonal expansion and contraction. Newer suburbs like Hoffman Estates or South Barrington have integrated duct systems designed for A/C from the start, with fewer failure-prone retrofits. Call (224) 344-8881 for a written estimate on sealing your specific configuration.
For Arlington Heights’s retrofitted heat-era systems, we recommend inspection every 18-24 months and cleaning every 3-4 years, more frequently if you have pets, recent renovation dust, or occupants with respiratory sensitivity. The Lake Michigan humidity cycle here promotes faster debris accumulation and mold-prone conditions than drier inland markets. Call (224) 344-8881 to schedule a camera inspection and we’ll show you what’s actually inside your trunk lines.
Slab-embedded ductwork can be sealed with specialized aerosol sealant injection or accessed through strategic ceiling modifications, but we won’t recommend either until we’ve run a camera and pressure test to locate the specific leak points. Some slab ducts are beyond practical repair and require rerouting; we’ll tell you that in writing before proposing any work. Call (224) 344-8881 for an honest assessment.
Proper sealing restores airflow to the upper level that was starved when leaks in the trunk line or flex-to-metal junctions diverted conditioned air into wall cavities. On a typical Arlington Heights split-level, we see register flow increases of 25-40% at second-floor supplies after sealing, with corresponding reductions in blower motor strain and energy consumption. The homeowner receives photo documentation of every sealed joint. Call (224) 344-8881 for a written estimate.
Yes. We measure blower motor amp draw before and after sealing work, because restricted airflow from duct leaks forces the motor to overwork. If we find the motor is out of spec or the air handler cabinet has leaks at its own seams, we document it with photos and include repair options in the written scope. Haven Standard Clause 1 requires everything in writing before any panel comes off. Call (224) 344-8881 to schedule.
