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 Irving: What to Know First
We provide independent Aprilaire duct repair and sealing in Irving, with most jobs scheduled within a few business days and completed in a single visit. A written price is delivered before any panel comes off, and every duct run is photographed before and after. Typical Aprilaire duct sealing and repair work in Irving runs $340-$780 for most residential systems, depending on whether we’re sealing accessible metal trunk lines or replacing collapsed flex sections in an attic that’s 110 degrees by noon. This page is for homeowners in Irving, Las Colinas, and Valley Ranch who own Aprilaire whole-home air cleaners, humidifiers, or ventilation systems and need the ductwork that feeds them actually fixed, not just vacuumed. Call (682) 297-4068 for a free estimate.
How Aprilaire Products Fail - and How We Fix Them
- Model 5000/5010 Electronic Air Cleaner - Seal Failure at the Media Cabinet The cabinet that houses the filtering media is built with a gasket seal that compresses over time, especially in Irving’s heat-cycling climate where attic temperatures swing 40 degrees in a day. Once the seal goes, unfiltered attic air bypasses the unit entirely. We remove the cabinet, reseat it with fresh gasket material, and seal the return plenum (the large box that distributes air to the furnace) with mastic sealant - not foil tape, which peels in Texas attic heat.
- Model 600/700 Humidifier - Duct Collapse at the Bypass Connection The 6-inch round bypass duct that feeds these humidifiers is often flex duct run through a hot Irving attic. After five to seven years the wire helix fatigues and the duct collapses at the elbow, cutting humidifier output to zero. We replace the flex section with insulated flex rated for attic exposure, support it with proper hangers every four feet, and seal both ends with mechanical clamps plus mastic.
- Model 8126X Ventilation Controller - Negative Pressure and Duct Leakage This whole-home ventilator creates deliberate negative pressure to exhaust stale air. If the supply ductwork has leaks - common in Irving homes built 2015-2020 with quick-seal jobs - the unit pulls attic air, insulation fragments, and summer heat straight into the living space. We pressure-test the duct system, identify leakage points with a smoke pencil, and seal with mastic or replace damaged sections. The 8126X then performs as designed instead of working against itself.
- Model 1910/1925 Dehumidifier - Disconnected Drain and Secondary Duct Damage The condensate drain on these units backs up or disconnects, saturating nearby duct insulation. In Irving’s humidity, mold-like growth follows within a season. We repair the drain connection, cut out water-damaged flex or fiberglass-lined metal duct, replace with new material, and seal all joints. The photo record shows exactly what was removed.
- Model 360/363 Through-Wall Ventilator - Improper Original Sealing Around the Sleeve These units require a tight seal between the wall sleeve and the building envelope. Irving’s clay soil and foundation movement often crack this seal within three to five years, creating a direct path for outdoor air, pollen, and attic dust. We remove the unit, reseal the sleeve with backer rod and sealant appropriate for the wall type, and verify with a blower-door-informed pressure check.
Our Aprilaire Duct Repair & Sealing Process

- 1
Call and schedule. A live person answers. We ask which Aprilaire unit you have, the symptoms you’ve noticed, and when you’re available. No phone diagnosis - that’s what the visit is for.
- 2
Arrival and inspection. The technician, identified by name before arrival, photographs the accessible ductwork and the Aprilaire unit. We show you what the camera sees. “The photo doesn’t lie - let’s look at it together before we talk about next steps.”
- 3
Written price delivered. Based on what was found, we provide a written price for the exact scope. Haven Standard Clause 1: no work starts until you have that number in hand.
- 4
Repair with documented parts. We use OEM Aprilaire parts where they matter for warranty compatibility, and quality aftermarket where they don’t - always named on the invoice. Mastic sealant, mechanical fasteners, proper support hangers. No shortcuts.
- 5
Test and verify. We run the system, check airflow at the registers (the grilles in your rooms), and confirm the Aprilaire unit is operating within manufacturer spec.
- 6
Photo record delivered. Before-and-after images of every duct run, plus the written scope and the 365-Day Done Right Promise, are yours to keep.

What moves the price: attic accessibility (Irving’s older Las Colinas homes often have tight scuttle holes), extent of water or mold damage requiring material replacement versus simple sealing, and whether the Aprilaire unit itself needs repositioning to correct an original installation error. Every estimate is free. Call (682) 297-4068.
Why Irving Homeowners Call CleanRun Air Duct Cleaning Irving for Aprilaire Work

We’ve been running service calls in Irving, including the Las Colinas corridor and Valley Ranch, since establishing our operation in 2013. Every job carries the 365-Day Done Right Promise in writing - not a policy, a signed document. 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 mixed-brand HVAC setup and the problem is at the junction, not the unit itself. The photo record is included on every visit, not an upsell. Tomas Reyes, who grew up in the Bronx and learned HVAC fundamentals at Bronx Community College, built this practice on documented evidence - written prices, photographed results, and accountability after the truck leaves.
FAQs
No, independent service does not void the manufacturer’s product warranty, provided the repair is performed to manufacturer specifications and OEM parts are used where specified. As an independent Aprilaire service provider, we document exactly what parts were installed and how, so warranty claims remain straightforward if you ever need them. Call (682) 297-4068 if you have questions about your specific unit.
Replacement is necessary when the camera shows collapsed flex, separated duct liner, or rust-through in metal trunk lines - damage that sealing cannot restore. Repair suffices for gasket failure, small leaks at joints, or disconnected sections. We show you the photos and explain which category your system falls into before any work is priced.
Yes. We stock common Aprilaire gaskets, bypass duct fittings, and media cabinet seals on our Irving-based trucks. Less common items arrive within one to two business days from regional distributors. If your job requires a wait, we tell you before you schedule.
Most residential jobs are completed in two to four hours. A simple media cabinet reseal might run ninety minutes; a full bypass duct replacement with attic work takes longer. We give you a time estimate with the written price, so you can plan your day.
We test. After sealing, we verify airflow at the registers, check static pressure where accessible, and confirm the Aprilaire unit is drawing and delivering air as designed. The photo record shows sealed joints; the test data shows function. Both are included in your job documentation.
