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.
Aprilaire Duct Repair & Sealing in Leander: What to Know First
We provide independent Aprilaire duct repair and sealing in Leander, with most jobs completed in a single scheduled visit and a written price delivered before any panel comes off. Typical repairs run from $340 for a straightforward flex-duct seal to $1,200 for full metal-duct restoration with mastic and insulation replacement in a larger home. As an independent Aprilaire service provider, we stock OEM and quality aftermarket parts for the 1600, 1800, and 2000 series ventilation systems we see most often in Leander’s 2015-2025 builds.
This page is for homeowners who recognize the Aprilaire badge on their air cleaner or ventilation controller and need the ductwork behind it sealed, repaired, or insulated. If you’re in Crystal Falls, Travisso, or anywhere in Leander and you’ve noticed uneven room temperatures, rising energy bills, or dust that keeps coming back, the duct run connected to your Aprilaire system is the first place we look. Call (737) 252-1285 for a free estimate.
How Aprilaire Products Fail - and How We Fix Them
- Model 1820 dehumidifier supply duct separation. The 1820’s compact cabinet gets shoehorned into tight Leander attic spaces, and the short flex-duct jumpers to the main trunk dry out faster than the manufacturer spec suggests in our heat. We’ve replaced cracked 1820 supply boots in the Paloma Lake area where the attic hits 140°F in July. We use reinforced flex with a UV-rated outer jacket and double-worm gear clamps, not zip ties.
- Model 1625 fresh-air intake register gasket failure. The 1625’s motorized damper seals against a foam gasket that turns to dust after four or five Leander summers. Homeowners call thinking the damper motor failed; the camera shows a 3-inch gap at the gasket edge. We source the OEM gasket kit or fabricate a silicone replacement that outlasts the original. Show the photo first. Then talk about what comes next.
- Model 2000 whole-home ventilator cross-break in the plenum. The 2000 series moves serious CFM, and when the transition plenum wasn’t built with a cross-break (that X-shaped crease that stiffens sheet metal), the pressure pulses eventually crack the seam at the weld. We find this in Leander’s faster-built 2019-2021 inventory. Our fix: remove the plenum, add a proper cross-break, reseal with water-based mastic, and pressure-test before reconnecting.
- Model 1850 condensate drain pan duct saturation. The 1850’s drain pan overflows silently when the P-trap dries out, and the wet insulation on the downstream duct run collapses. We’ve pulled saturated flex duct in the Leander Highlands neighborhood where the homeowner smelled mold before seeing any water. We replace the damaged duct, re-insulate with R-6 flex, and install a trap primer so it doesn’t repeat.
- Model 1610 bypass damper duct collapse. The 1610’s bypass loop is often installed with light-duty flex that kinks when the damper slams shut. The restriction shows up as a whistling noise and a pressure imbalance that throws off the whole system. We replace the bypass run with hard-pipe where possible, or reinforced flex with an internal helix wire, and rebalance the static pressure with a digital manometer.
Our Aprilaire Duct Repair & Sealing Process

- 1
Inspection with photo documentation. We run a borescope through every accessible duct run connected to your Aprilaire unit and photograph what we find. You get these images whether or not you hire us.
- 2
Written scope and price. Haven Standard Clause 1: the price is written and agreed before any work starts. No exceptions. We specify OEM or aftermarket parts and why.
- 3
Parts verification. For Aprilaire-specific components, we verify part numbers against your unit’s serial plate. For universal items like flex duct or mastic, we use trade-recognized brands - Guardsman insulation, Abatement Technologies containment where needed.
- 4
Repair and seal. We execute the repair, seal with mastic or foil tape as appropriate, and replace any compressed or water-damaged insulation. Every joint is accessible for future inspection.
- 5
Pressure test and photo record. We run a negative-pressure test to confirm seal integrity, then photograph the completed work. The before-and-after set goes in your job record.
- 6
365-Day Done Right Promise in writing. If the repair fails or the seal opens, we make it right. The promise is on your invoice, not just our website.

Why Leander Homeowners Call CleanRun Air Duct Cleaning Leander for Aprilaire Work

We’ve been running crews in Leander since 2013, and the Aprilaire systems in this market have specific patterns we now recognize on sight. The cedar pollen load here is real, and when a 1625 fresh-air intake gasket fails, the debris load inside the duct run is different from what we see in Houston or Dallas. Tomas Reyes, our owner, spent years working HVAC in the Northeast before relocating to Leander, and he built our protocol around documentation you can verify - photos, written prices, written guarantees.
Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so when your Aprilaire is integrated with another brand’s air handler, we don’t guess at the interface. Every job carries the 365-Day Done Right Promise and a Free Second Opinion on any competitor’s written estimate.
FAQs
No, independent repair of the ductwork connected to your Aprilaire unit does not void the manufacturer’s product warranty, provided the work is done to code and doesn’t modify the unit’s electrical or control systems. We document our methods with photos so there’s a clear record of what was touched and what wasn’t. Call (737) 252-1285 if you’d like us to review your warranty terms before scheduling.
We use OEM parts for Aprilaire-specific components like damper motors, gasket kits, and control boards. For universal materials like flex duct, mastic, and insulation, we use professional-grade aftermarket products from Guardsman and Abatement Technologies that meet or exceed OEM specifications. We tell you which is which on the written scope.
Repair is viable when the damage is localized - a cracked plenum, a separated flex run, a failed gasket. Full replacement makes sense when the duct system has multiple failure points, outdated insulation, or design flaws like undersized returns that no single repair can fix. Our inspection camera shows you exactly which category you’re in before you commit to anything. Call (737) 252-1285 for a free assessment.
We schedule Aprilaire duct repair within a few business days, sometimes sooner depending on crew availability in your area. We don’t do “same-day” urgency theater because proper duct repair takes time we won’t rush. You’ll get a specific arrival window, and your technician calls 30 minutes out.
We test it. Every sealed system gets a negative-pressure verification test - we measure static pressure before and after the repair with a digital manometer, and the numbers go in your job record along with the before-and-after photos. If the pressure doesn’t improve, we don’t call the job complete. Call (737) 252-1285 to schedule.
Ready to get your Aprilaire ductwork sealed right? Call CleanRun Air Duct Cleaning Leander at (737) 252-1285 for a free, written estimate. We’ll show you what the camera sees, name a flat price before any work starts, and back the repair with our 365-Day Done Right Promise.
