This page is for homeowners in Lewisville, Castle Hills, and the surrounding area who have an Aprilaire whole-home air cleaner, humidifier, or ventilation system connected to ductwork that is leaking, sagging, or pulling loose from its registers. If your Aprilaire unit is working but your rooms aren’t heating or cooling evenly, the problem is often in the ducts, not the unit. Call (940) 240-8552 for a free estimate with a written price before we start.

How Aprilaire Products Fail - and How We Fix Them

• Model 5000 Electronic Air Cleaner: The cabinet is heavy and mounts directly to the return plenum. Over years, the weight stress cracks the mastic seal where the cabinet meets the duct board, especially in Lewisville’s summer heat cycles that expand and contract the metal. We remove the unit, re-seal with fresh mastic, and reinforce the connection with mechanical supports so the seal holds.
• Model 600 and 700 Humidifiers: The bypass or fan-powered duct connections are 6-inch round taps that often loosen where they penetrate the supply plenum. The humidifier itself runs fine, but conditioned air leaks into the attic or wall cavity through the degraded grommet. We replace the factory grommet with a reinforced collar and re-seal with mastic rated for the temperature swing.
• Model 8126X Ventilation Controller: This unit’s intake and exhaust duct runs are often flex duct stretched across long attic distances in newer Lewisville builds from 2015 to 2022. The negative pressure from the ventilator collapses cheap flex duct at elbows, restricting airflow and straining the fan motor. We replace collapsed sections with properly supported flex or convert to rigid metal where the run allows.
• Model 1910 Dehumidifier: The return and supply connections on this whole-home unit are 10-inch flex duct that sags in hot attics, creating low spots where condensation pools and microbial growth follows. We lift the sag with proper strapping, replace water-damaged duct, and verify the slope drains correctly to the condensate line.
• Model 1210 and 1410 Media Air Cleaners: These 5-inch media cabinets have a smaller footprint than the 5000 series, but the thinner return duct connections are prone to separation at the starting collar in homes near Lewisville’s older Castle Hills section where original ductwork was undersized for the static pressure. We reinforce the collar connection and upgrade to a heavier-gauge starting collar when the original has fatigued.

Our Aprilaire Duct Repair & Sealing Process

1. 1
   Visual and camera inspection. We photograph the inside of every accessible duct run, the plenum connections, and the Aprilaire unit mounting points. The camera showed a 3-inch debris build-up at the first elbow on a job we ran last month in Castle Hills.
2. 2
   Written scope and price. Before any panel comes off, we deliver a written price for the exact work needed. Haven Standard Clause 1: No work starts without a written price agreed in writing.
3. 3
   Parts decision. For Aprilaire-specific collars, grommets, and cabinet gaskets, we use OEM when the part is available and the price is reasonable. For standard duct connections and flex duct, we use quality aftermarket from trade-recognized manufacturers that meet or exceed OEM spec.
4. 4
   Repair and seal. We re-seal with mastic, replace degraded flex or damaged metal, and reinforce connections with mechanical supports. Every joint is pressure-tested where accessible.
5. 5
   Photo documentation and test. We photograph the completed work, run the system, and verify airflow at the registers. The customer receives the before-and-after photo record as a standard deliverable.
6. 6
   Written guarantee. The 365-Day Done Right Promise is documented on the invoice before we leave.

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

We’ve been running jobs in Lewisville since 2013, including plenty of older homes near Castle Hills where the flex duct tends to sag and accumulate debris in ways that don’t show up until you put a camera inside. Tomas Reyes, our owner, picked up his HVAC fundamentals at Manhattan’s Apex Technical School and has spent two-plus decades working inside ductwork across North Texas. He built CleanRun around one habit: photographing what’s in the duct before and after, so the homeowner can see exactly what changed and for how much.

Every job is backed by the 365-Day Done Right Promise in writing, not as a policy subject to manager approval. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, which matters when your Aprilaire unit is integrated with a multi-brand HVAC setup and the problem could be in either component. Here’s the before photo. Now let’s talk about what happens next.
