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.

Duct repair and sealing in Scottsdale typically costs $340-$1,200 depending on the scope, with most residential jobs completed in a single visit. CleanRun Air Duct Cleaning Scottsdale has performed this work since 2013, and every job starts with a written price before any panel comes off. Call (928) 267-0992 for a free estimate with no obligation to proceed.
Scottsdale’s desert climate puts unusual stress on ductwork. Summer attic temperatures regularly exceed 140°F, which hardens flexible duct insulation, cracks mastic seals, and loosens metal connections that were tight in March. We’ve documented this pattern across 52,000+ homes: the thermal expansion cycle here is more aggressive than in coastal or mountain climates, and it shows up as cooled air leaking into attics, garages, and wall cavities before it ever reaches the register.
We’re not guessing. Every duct repair and sealing job we perform in Scottsdale includes a Documented Photo Record of every duct run, before and after, delivered to you as part of the standard job record. You’ll see exactly where the leaks were, what we sealed, and what the finished work looks like. This practice has been non-negotiable since our first job in 2013, and it’s how we back the 365-Day Done Right Promise in writing, not just in marketing copy.
What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, cracks, and disconnected joints that allow conditioned air to escape your supply ducts or pull unconditioned attic air into your return path. In Scottsdale, we most often find failed seals at plenum connections, the box where your air handler meets the main trunk line, and at register boots where ducts terminate at your ceiling or wall. Our crews use professional-grade mastic and reinforced tape rated for Arizona’s temperature extremes, not the hardware-store foil tape that degrades in two summers. Every sealed joint is photographed before and after, and the images are included in your job record.
Flex Duct Repair
Flex duct, the insulated flexible tubing common in homes built after 1990, collapses, tears, or separates at its collar connections when attic heat degrades the inner liner. We replace damaged flex duct with new R-8 insulated runs sized to your system’s CFM requirements, and we support every run with proper strapping to prevent sagging that creates airflow restrictions. In Scottsdale’s 85254 and 85255 zip codes, we’ve found that flex duct installed during the 2012-2018 building boom is now reaching the failure window, particularly in two-story homes where attic temperatures peak highest.
Metal Duct Repair
Metal ductwork, found in older Scottsdale homes and in commercial applications, develops seam separations and corrosion at joints where condensation collects against uninsulated surfaces. We repair metal ducts by resealing seams with mastic sealant, replacing rusted sections with galvanized steel, and adding insulation where thermal bridging has caused chronic sweating. Our crews carry sheet metal tools and crimpers to fabricate custom fittings on site, so we’re not cobbling together mismatched parts from a hardware run.
Duct Insulation
Duct insulation prevents the 140°F attic air of a Scottsdale July from warming your cooled supply air before it reaches the register. We install R-8 or R-6 fiberglass wrap on uninsulated metal ducts, and we replace degraded flex duct insulation where the vapor barrier has torn and the fiberglass has compressed. The difference is measurable: we’ve photographed supply registers in Paradise Valley homes where uninsulated ducts were delivering 58°F air at the plenum but 71°F air at the register, a 13-degree loss that your compressor works overtime to overcome.
Mastic Sealant
Mastic sealant is a thick, water-based compound brushed or troweled onto duct joints, then cured to a flexible, airtight seal that outlasts tape in high-heat environments. We apply mastic to every metal seam, plenum connection, and register boot on repair jobs, and we use it as the primary seal on new duct installations. Unlike tape, mastic fills irregular gaps and maintains its bond through thousands of thermal expansion cycles, which matters in Scottsdale where ducts expand and contract dramatically between May and September.
Air Leak Repair
Air leak repair targets the specific points where your duct system loses pressure, identified through smoke testing or thermal imaging during our initial assessment. Common leak sites in Scottsdale include penetrations where electrical or plumbing lines pass through duct walls, poorly sealed access panels, and gaps around filter racks where unfiltered attic air bypasses your filter entirely. We document each leak location photographically, repair with appropriate materials for the substrate, and verify with a follow-up pressure test when the scope warrants it.

Brands We Service for Duct Repair & Sealing
Our crews work with the equipment manufacturers that supply Scottsdale’s HVAC trade. We’ve installed and sealed ductwork connected to Honeywell zoning systems in north Scottsdale homes, where motorized dampers require precise duct pressure balancing to operate correctly. Our experience with Honeywell controls means we understand how duct leakage affects zone performance, and we test for it before declaring a job complete.
We also regularly service ducts tied to Aprilaire whole-home dehumidifiers and air cleaners, common in the 85266 and 85262 areas where homeowners have invested in indoor air quality upgrades. Aprilaire units depend on tight ductwork to maintain the pressure differentials their media filters and ventilation controls require. We’ve repaired duct leaks that were causing Aprilaire ventilators to draw unfiltered attic air rather than fresh outdoor air, a failure mode that shows up as dust accumulation and poor humidity control. Whether your system includes Honeywell, Aprilaire, or any other make, we can assess your ductwork and deliver a written repair scope.
BeforeAfterSigns You Need Duct Repair & Sealing Right Now
- Rooms that won’t hold temperature. If your west-facing bedroom in Scottsdale runs 8-10 degrees warmer than the thermostat setting while the rest of the house cools normally, the duct run serving that room is likely disconnected, crushed, or leaking into the attic. This is one of the most common calls we receive from homeowners in 85259 and 85260.
- Dust that returns within days of cleaning. When ducts leak on the return side, they pull attic air loaded with insulation fibers, desert dust, and rodent debris directly into your airflow. If you’re wiping white fiberglass dust from your registers monthly, your return ductwork has a breach that filtration won’t fix.
- Unusually high summer electric bills. A 20% duct leakage rate can increase cooling costs by 30% or more in Scottsdale’s climate, because your compressor runs longer to compensate for air that never reaches the conditioned space. We see this pattern most often in homes where original flex duct has aged past 15 years.
- Whistling or rushing air sounds from walls or ceilings. These noises indicate high-velocity air escaping through a gap under pressure, often at a register boot that has separated from the ceiling drywall. The sound is the symptom; the energy waste and drywall moisture damage are the consequences.
- Hot spots in rooms directly below the attic. In Scottsdale’s single-story ranch homes, particularly those built in the 1970s and 1980s near Shea Boulevard and Scottsdale Road, uninsulated or leaking supply ducts in the attic deliver warmed air to ceiling registers. The room never feels right because the duct is working against itself.
Our Duct Repair & Sealing Process - Step by Step
- 1
Written estimate before work begins. We inspect your accessible ductwork, identify visible damage, and deliver a written price for the agreed scope. Haven Standard Clause 1 requires this: no verbal quotes, no “we’ll see what we find,” no invoice surprises. You’ll know the exact cost before we remove our first panel.
- 2
Documented Photo Record of existing conditions. Our technician photographs every duct run, plenum connection, and register boot before touching anything. These images establish baseline conditions and often reveal problems the homeowner wasn’t aware of, a disconnected return in a garage attic, for example, that had been pulling car exhaust into the system.
- 3
Targeted repair and sealing. We perform the agreed scope using materials appropriate to each substrate: mastic and reinforced mesh for metal seams, new flex duct and proper supports for collapsed runs, R-8 insulation wrap for thermal bridging. Our crews use professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, brands you can verify independently.
- 4
Pressure verification and airflow testing. Where the scope includes system-wide sealing, we verify results with a duct blaster or static pressure test to confirm the leakage reduction. We don’t claim improvement; we measure it when the job scale warrants.
- 5
Final Documented Photo Record and written completion. Every repaired joint, replaced section, and sealed connection is photographed after work. These images, with the written scope and 365-Day Done Right Promise, comprise your job record. It’s delivered before we leave, and it’s your documentation if any question arises later.
How Much Does Duct Repair & Sealing Cost in Scottsdale?
A typical duct sealing job for a single-family home in Scottsdale runs $340-$680 for accessible supply and return sealing, depending on system size and attic accessibility. Flex duct replacement, when one or two runs have collapsed or torn, typically falls in the $280-$520 range per run. More extensive work, multiple flex duct replacements, metal duct repair with custom fabrication, or full system insulation, can reach $800-$1,200.
Several factors move the price within these ranges. Attic accessibility matters: truss-framed attics with limited clearance take longer to navigate than scissor-truss or flat-roof designs common in some Scottsdale ranch homes. The extent of existing damage affects material quantities; a single disconnected register boot is a 30-minute repair, while a rodent-damaged return plenum may require full replacement. System size drives scope: a 5-ton system with 12 supply registers has more joints to seal than a 2.5-ton system with 6.
We avoid the pricing practices that create invoice shock. CleanRun does not quote per-vent or per-register prices that balloon once the crew is on site. We do not offer teaser coupons that exclude the actual work you need. Every price is whole-system, written, and agreed before work starts. If you’ve received a written estimate from another company, we provide a Free Second Opinion at no cost, our number next to theirs, both in writing.
Your estimate includes the full scope, all materials, the Documented Photo Record, and the 365-Day Done Right Promise. There are no trip charges, no diagnostic fees, no separate line items for “equipment” or “setup.” Call (928) 267-0992 for an exact quote on your system, estimates are free and carry no obligation to schedule.

Frequently Asked Questions - Duct Repair & Sealing in Scottsdale
Duct repair and sealing fixes the physical damage and air leaks in your home’s forced-air distribution system. The work includes reconnecting separated joints, replacing collapsed or torn flex duct, sealing metal seams with mastic, and insulating where thermal losses occur, so the air your HVAC conditions actually reaches your rooms instead of leaking into the attic. Every CleanRun job concludes with a Documented Photo Record showing what was found and what was corrected.
Most residential duct sealing jobs in Scottsdale are completed in 2-4 hours; flex duct replacement or metal repair may extend to a full day if multiple runs or custom fabrication is involved. We schedule based on the written scope, not an optimistic guess, and we don’t rush work that requires attic access in July heat. Your written estimate includes the expected duration so you can plan accordingly.
Duct sealing for a typical Mesa home runs $340-$680; flex duct replacement is $280-$520 per run; extensive repairs or insulation work can reach $800-$1,200. The exact price depends on system size, attic accessibility, and the extent of existing damage. We deliver a written, whole-system price before any work begins, no per-vent add-ons, no coupon bait-and-switch. Call (928) 267-0992 for a free estimate on your specific system.
Yes. We regularly repair and seal ductwork connected to Honeywell zoning controls and Aprilaire air quality equipment, and we service all standard HVAC makes regardless of brand. Our crews understand how duct pressure and leakage affect the performance of these integrated systems, and we test for proper operation before completing the job. Bring us any system, we’ll assess the ductwork and deliver a written scope.
We do not advertise emergency or same-day dispatch for duct repair, because this work requires proper attic access, material preparation, and daylight for safe work and accurate documentation. However, our phones are answered by a live person 24/7, and we prioritize urgent situations, a fully disconnected main trunk, for example, in our scheduling. Call (928) 267-0992 to discuss your timeline; we’ll be direct about when we can perform the work correctly.
Every duct repair and sealing job is backed by our 365-Day Done Right Promise: if the work is not right, we make it right, documented in writing on every invoice, not subject to manager approval. Haven Standard Clause 4 requires this accountability. The promise covers materials and workmanship; if a sealed joint fails or a replaced flex duct separates within one year, we return and correct it at no charge.
Clear a path to your attic access, typically a hallway or closet hatch, and remove any stored items directly beneath it. Ensure pets are secured away from work areas, as attic access requires ladder placement and panel removal that can disturb animals. You don’t need to move furniture or cover belongings; our crews use drop cloths and containment practices as part of the H.A.V.E.N. Standard. We’ll confirm any specific preparation when we schedule.
