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.

This page is for Plano homeowners who see uneven airflow from their Aprilaire-integrated HVAC system, hear whistling at registers, or have been told their ducts “leak a little” without anyone showing them exactly where. If you’re researching before calling, you’re the customer we built CleanRun for.
How Aprilaire Products Fail - and How We Fix Them
- Model 8140 and 8144 Whole-House Ventilators: The flex duct connections on these ventilators fatigue where they meet the plenum in Plano’s attic heat, which regularly exceeds 140°F from June through September. The corrugated flex collar cracks at the clamp line, pulling unconditioned attic air into the supply stream. We replace with insulated flex rated for the temperature swing and seal with mastic, not tape, because tape adhesive fails in that environment within two seasons.
- Model 1820 and 1830 Dehumidifier Drain Lines: These units tie into the main duct system and their PVC drain lines are often routed through the same chase. When the drain backs up, water pools at the duct boot and rusts out the connection. We’ve found this in at least a dozen Plano homes built between 2015 and 2019, particularly in the Willow Bend area where slab foundations limit drainage slope. We repair the duct boot, reroute the drain for proper fall, and photograph the water line so the homeowner sees why the duct failed.
- Model 500 and 600 Humidifier Bypass Ducts: The 6-inch round bypass duct on these humidifiers is frequently installed with a single screw clamp and no support strap. Over years of cycling, the weight of the humidifier body sags the bypass collar, creating a gap that leaks conditioned air into the return. Our fix is a supported transition with a reinforced collar and two clamp points, plus a pressure test to confirm the bypass closes fully when the humidifier is off.
- Model 8900 and 8920W Wi-Fi Thermostat Duct Integration: These thermostats control zoning dampers that live inside the ductwork. When a damper actuator fails, homeowners often blame the thermostat. The real issue is a stuck damper forcing air against a closed blade, which eventually blows out the duct seam. We test the damper independently, replace the actuator if needed, and seal the reinforced seam so the zone control works as designed.
- Model 1210 and 2210 Air Cleaner Duct Transitions: The cabinet on these media air cleaners is wider than the standard duct run, so installers use a transition piece that creates two additional seams. In Plano’s clay-soil expansion cycle, slab movement stresses these transitions until they separate. We find this most often in single-story ranch homes near the Shops at Legacy where the original 1990s ductwork was retrofitted with the air cleaner. Our repair replaces the transition with a custom-fabricated piece and seals all four seams with mastic and mesh.
Our Aprilaire Duct Repair & Sealing Process

- 1
Photo-first inspection. We run a camera through every accessible duct run and photograph the failure point before touching a tool. Tomas Reyes started this practice when he founded CleanRun in 2013, and we still do it on every job. Show the photo first. Talk second.
- 2
Written scope and price. We deliver a written price before any work starts, under Haven Standard Clause 1. The scope names the parts, the labor, and the test method. No verbal estimates, no “we’ll see how it goes.”
- 3
OEM or verified aftermarket parts decision. For Aprilaire-specific components like bypass collars and transition cabinets, we source OEM when the warranty is active. For standard duct materials, we use quality aftermarket rated to the same pressure and temperature specs, and we document the part number in the job record.
- 4
Repair and seal. We repair or replace the failed section, seal with mastic and fiberglass mesh (not tape alone), and support any flex run with straps at 4-foot intervals per SMACNA guidelines.
- 5
Pressure test and photo documentation. We test static pressure before and after the repair with a calibrated manometer, and we photograph the completed work. The customer receives both sets of photos and the pressure readings as part of the standard job record.
- 6
365-Day Done Right Promise activation. The written guarantee goes into the job file. If the repair fails, we make it right. Not a policy subject to manager approval. A written promise.

Why Plano Homeowners Call CleanRun Duct Repair & Cleaning for Aprilaire Work

We’ve served 52,000 homes since 2013, every one with a written price before work started and a documented photo record when we left. The 365-Day Done Right Promise is backed in writing on every job, not just stated in marketing copy. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they know Aprilaire product lines well enough to distinguish a bypass duct failure from a humidifier control issue without guessing.
We also service Lennox, Trane, and Carrier systems, which matters when your Aprilaire components are integrated with a mixed-brand HVAC setup and the failure point could be in either system. Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands you can look up independently before you agree to a price.
Tomas Reyes and his crew have worked throughout Plano for years, including jobs in the older ranch-style homes near the Shops at Legacy where original flex duct from the early 1990s still surprises even experienced techs. That local familiarity means we know what to expect before we open the attic hatch.
FAQs
No, independent duct repair does not void Aprilaire’s product warranty, provided the repair does not alter the core unit and uses parts of equivalent specification. As an independent Aprilaire service provider, we document the part numbers and installation method in your job record so warranty questions are answerable with evidence. Call (469) 452-7766 if you need help interpreting your warranty terms.
We recommend replacement when more than 30% of the total duct run shows failure, when the original duct is uninsulated flex in a Plano attic (where summer heat accelerates degradation), or when previous repairs have created a patchwork that leaks at every junction. Otherwise, localized repair with proper sealing is usually the better value. We show you the camera evidence and write both options with prices so you decide from fact, not pressure.
We source Aprilaire OEM parts for proprietary components like bypass collars, transition cabinets, and control boards when the warranty is active or when the part has no verified aftermarket equivalent. For standard duct materials - flex, metal, mastic - we use quality aftermarket rated to the same pressure and temperature specifications, and we name the manufacturer in the written scope. You see what you’re getting before you agree.
Most single-point repairs are completed in two to four hours. Multi-run replacement or custom fabrication can extend to a full day. We schedule by the job, not by the hour, so the crew stays until the pressure test passes and the photo record is complete. You’ll know the expected duration when you receive the written scope.
You receive a documented photo record of every duct run, before and after, plus the manometer pressure readings from pre-repair and post-repair testing. This is included as a standard deliverable on every CleanRun job, not an add-on. If a company won’t show you the inside of your ducts, you’re buying a promise, not a service.
