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 Tempe
Most duct repair calls we take from Tempe aren’t from homeowners who noticed a problem last week. They’re from property managers whose blower motor is cycling hard on a 112°F day, or from tenants in converted ranch homes near Arizona State University whose utility bill suddenly spiked. Our crews are dispatched from the Phoenix office and serve Tempe directly, carrying mastic, flex duct, and metal repair stock sized for the 1950s-70s slab-on-grade ranches that dominate this city’s housing stock. Call (928) 267-0992 for a written estimate before any work starts.
Why CleanRun Air Duct Cleaning Scottsdale Is Tempe’s Preferred Duct Repair & Sealing Company
We’ve been documenting the inside of every duct run we touch since 2013, and that practice matters more in Tempe than most places. The rental corridor around Apache Boulevard and Maple-Ash turns over tenants faster than ductwork gets inspected, so when we open a register, we’re often the first people to look in five or ten years. Our Duct Repair & Sealing team arrives with a camera, a written price, and the H.A.V.E.N. Standard crew verification that Tomas Reyes built into every job.
Our reputation in Tempe is built on what we can show, not what we say. Every customer receives a Documented Photo Record of every duct run, before and after, as a standard deliverable - not an upsell. The 365-Day Done Right Promise is backed in writing on every invoice, not buried in a policy manual. When a property manager in the ASU corridor calls us back, it’s because the photo record from the first job proved the work happened, and the written price meant no invoice surprises.
Scheduling runs from our Phoenix office, so Tempe customers get next-day availability without the markup of a distant franchise dispatch model. Technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews.
Our Duct Repair & Sealing Services in Tempe
Duct Sealing
Tempe’s attic temperatures destroy seals. In a 150°F attic, the mastic and foil tape applied in 1972 has long since cracked, and every gap pulls monsoon dust straight into the living space. We seal plenum boots, trunk connections, and register boots with fresh mastic rated for attic heat, then verify leak reduction under negative pressure. A typical duct sealing job in Tempe runs $380-$720 for a single-system ranch home, with written price delivered before we touch a panel.
Flex Duct Repair
The flex duct in Tempe’s older ranches wasn’t designed for six-month cooling seasons and attic heat cycling. We replace crushed, kinked, or heat-brittled flex sections with new insulated flex sized to the original CFM load, secure it with mechanical straps rather than tape alone, and photograph every connection. Flex duct repair in Tempe typically costs $180-$340 per run, depending on attic access and length.
Metal Duct Repair
Some Tempe homes, especially the 1960s builds near Rural Road and Broadway, have galvanized metal trunk lines that have separated at seams or corroded at condensate collection points. We patch or replace metal sections, re-seal with mastic, and restore structural integrity. Metal repair runs $260-$580 in this market, with scope confirmed by camera before pricing.
Air Leak Repair
Leak detection in Tempe means accounting for pressurization differentials during haboob season, when outdoor particulate loads are highest. We pressurize the system, identify leak points with smoke or digital manometer, then seal and verify. Air leak repair is often bundled with sealing work; standalone detection and minor repair starts around $220 in Tempe.
Duct Insulation
Where attic flex has lost its insulation wrap to heat and rodent damage, we re-wrap or replace to restore R-value and prevent condensation in Tempe’s extreme temperature swings. Insulation work runs $140-$280 per run when bundled with repair.

Our trucks carry Rotobrush and Nikro equipment for mechanical cleaning and negative-pressure extraction, plus Honeywell and Aprilaire components for register and damper replacement. We stock flex duct, mastic, and mechanical fasteners sized for Tempe’s common 6-inch and 8-inch residential runs, so most repairs don’t wait on parts. Every tool and material is named on your written scope before work begins - no generic descriptions, no surprises.
Common Duct Repair & Sealing Problems We See in Tempe Homes
- Heat-degraded flex duct in 150°F attics. The original flex in 1950s-70s Tempe ranch homes sits in attic spaces that routinely hit 150-160°F in July and August. The plastic liner brittle-cracks, the insulation sags, and the wire helix collapses. We find this in subdivided rentals near Maple-Ash where the ductwork has never been replaced across multiple tenant cycles.
- Failed mastic and tape seals at plenum boots. Thermal expansion and contraction in Tempe’s attic heat cycles break the bond between metal boots and flex duct. During monsoon season, these gaps become intake points for haboob dust - ultrafine Sonoran Desert particulate that loads the system faster than in comparable desert cities.
- Shared dryer vent stacks in ASU rental conversions. When a single-family ranch near Apache Boulevard gets split into two or three units, the original dryer vent often becomes a common stack with no cleanout access. Lint packs the full vertical run. Tenants replace their dryer twice before anyone checks the duct behind the wall.
- Disconnected flex runs missed between tenants. Dense parking and restricted equipment access in the Apache Boulevard rental belt encourage quick exterior-only checks. Interior registers stay packed with dust columns, and disconnected flex runs blow conditioned air into the attic until the next crisis call.
Pricing for Duct Repair & Sealing in Tempe, AZ
We publish ranges because Haven Standard Clause 1 requires a written price before any work starts. Here is what duct repair and sealing costs in Tempe’s market:
| Service | Typical Range in Tempe |
|---|---|
| Duct sealing (single system) | $380 - $720 |
| Flex duct repair (per run) | $180 - $340 |
| Metal duct repair | $260 - $580 |
| Air leak detection + minor repair | $220 - $420 |
| Duct insulation (per run, bundled) | $140 - $280 |
Factors that move the price: attic accessibility (some Tempe ranches have scuttle holes too small for a technician with equipment), number of disconnected or crushed runs, and whether the air handler itself needs re-sealing. Multi-tenant conversions with shared stacks take longer to scope properly. Every estimate is free, every price is written, and every job includes the Documented Photo Record. Call (928) 267-0992 for your exact number.
We Also Serve Cities Near Tempe
Our Duct Repair & Sealing in Tempe crews also work in Mesa, Chandler, Gilbert, and Scottsdale. Each city gets the same written-price-first protocol and photo documentation, but the repair patterns differ: Scottsdale’s newer stock sees fewer attic-heat failures, while Mesa’s 1970s-80s builds have their own flex duct timeline. We adjust scope and pricing to the local housing stock, not a flat-rate sheet.

FAQs - Duct Repair & Sealing in Tempe
Tempe’s ASU rental corridor concentrates high-turnover units with original 1950s-70s ductwork in 150°F attics, while Scottsdale and Chandler have newer owner-occupied stock with better maintenance cycles. The combination of heat degradation and property-manager neglect means Tempe’s duct failures accumulate across multiple tenants before anyone calls. Call (928) 267-0992 and we’ll put a written scope and price to your specific building.
We coordinate access with the property manager in advance, arrive with compact equipment that fits tight Tempe rental lots, and schedule during tenant turnover windows when possible. Our technician is identified by name before arrival under Haven Standard Clause 3, and every unit’s ductwork is photographed separately for the property record. For buildings with shared air handlers, we seal at the trunk and verify each branch with a smoke test.
Blower motor cycling hard on hot days, rooms that won’t cool despite new filters, and dust blowing from registers immediately after cleaning all point to disconnected or leaking ductwork rather than dirty ducts. On a subdivided ranch near Apache Boulevard and Maple-Ash, our tech pulled registers on a turnover unit and found the supply and return ducts packed with years of desert grit and pet dander, while camera inspection showed collapsed flex duct runs and failed mastic at the plenum boot. We sealed the air handler and trunk connections with mastic, replaced the crushed flex sections, and verified leak reduction under negative pressure with HEPA filtration running, then restored airflow to the shared stack. The property manager only noticed because the blower motor was cycling hard on a 112°F day, but the underlying duct problem had been building across multiple tenants.
Yes. Tempe sits in the Salt River Valley’s haboob corridor, and ultrafine Sonoran Desert particulate - caliche dust, silica, organic debris - pressurizes against the building envelope during summer storms. Any gap in duct sealing becomes an intake point. We regularly find dust columns packed into registers in units where the mastic failed years ago. Sealing eliminates the pathway; cleaning alone just removes today’s accumulation.
ASU-area rental conversions often leave multiple units sharing a single dryer vent stack with no cleanout access. The common run packs with lint, creating backpressure that tenants mistake for a dryer failure. We treat the full stack as part of the building’s air distribution system: inspect the common run with a camera, replace or reroute where accessible, and seal connections to prevent lint migration between units. This is standard scope on multi-tenant jobs in the Apache Boulevard corridor.
