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.

AfterAprilaire Duct Repair & Sealing in Austin: What to Know First
We provide independent Aprilaire duct repair and sealing in Austin, typically completing standard jobs in one scheduled visit with a written price delivered before any panel comes off. Most Aprilaire systems we see in Austin homes run between $340 and $780 for full duct sealing or flex duct repair, depending on whether the plenum (the main distribution box attached to your air handler) needs resealing or replacement. This page is for homeowners who own an Aprilaire air cleaner, humidifier, or ventilation system and have noticed uneven airflow, rising utility bills, or dust escaping from duct joints. If that sounds like your situation, call us at (737) 243-9544 and we’ll send a written estimate with a photo record of what we find.
How Aprilaire Products Fail - and How We Fix Them
- Model 5000 Electronic Air Cleaner: The cabinet seal gasket hardens after five to seven years in Austin’s heat, creating a bypass gap that pulls unfiltered return air around the filter. We remove the unit, replace the gasket with OEM-spec material, and reseal the plenum connection so the 5000 actually filters what passes through it.
- Model 600/700 Humidifier Series: The bypass duct on these units is often installed with flex duct that sags at the first elbow, collecting condensation and mineral debris from the water panel. In Austin’s hard-water zones like Circle C Ranch and Steiner Ranch, we’ve found 2-inch debris buildups that restrict airflow to the humidifier and the main system. We replace the flex with properly supported metal duct or reinforced flex, pitched for drainage.
- Model 8126X Ventilation Control: The intake and exhaust duct runs on these energy recovery ventilators are frequently sealed with foil tape that degrades in attic temperatures above 140 degrees. We find separated joints in Austin attics every summer. Our fix is mastic sealant (a brush-applied, fiber-reinforced paste) rated for continuous high-heat exposure, plus mechanical fasteners at each joint.
- Model 1820/1830 Dehumidifier: The supply plenum connection on these whole-house units cracks where the plastic collar meets metal duct, especially in homes built during the 2019-2021 construction rush with rapid-cure sealants. We fabricate a transition piece and seal with mastic, not tape, because the thermal expansion differential between plastic and metal will reopen a tape seal within two years.
- Model 1410/1610 Media Air Cleaner: The filter track seal on these cabinet-style units compresses over time, allowing return air to bypass the media. In older Austin homes near Hyde Park and Clarksville, we’ve seen original installations where the cabinet itself was forced into an undersized return plenum, distorting the frame. We reseat or replace the cabinet, reseal the plenum, and verify with a pressure test.
Our Aprilaire Duct Repair & Sealing Process
- 1
Camera scope first: Tomas Reyes inspects every accessible duct run with a borescope camera before quoting. You see the image of what’s in your plenum before we discuss price.
- 2
Written price delivered: Haven Standard Clause 1 - one flat price per system, agreed in writing, before any work starts. No per-vent add-ons, no surprises.
- 3
Parts decision documented: We note whether we’re using Aprilaire OEM gaskets and collars or quality aftermarket equivalents, and why. Some discontinued 5000-series gaskets are only available aftermarket now; we source from Guardsman and Honeywell-certified suppliers, not generic hardware store stock.
- 4
Repair and seal: We disconnect the Aprilaire component, repair or replace the duct or plenum connection, apply mastic sealant to all joints, and reinstall with proper support. Flex duct gets strapped every four feet minimum.
- 5
Pressure test and photo record: We verify seal integrity with a static pressure reading, then photograph every run before and after. The photo record is delivered as part of your job documentation.
- 6
Written guarantee: The 365-Day Done Right Promise goes on your invoice. If the seal fails or the airflow problem returns, we make it right.

What moves the price: attic accessibility (Austin’s tight truss spaces add labor), whether the original installer left enough service clearance around the Aprilaire unit, and whether we’re matching existing flex duct or upgrading to metal. We also service Lennox, Trane, and Carrier systems with integrated Aprilaire accessories, which sometimes require manufacturer-specific transition fittings.
Every estimate is free. Call (737) 243-9544 and we’ll put a written number next to any competitor’s quote under our Free Second Opinion policy.
Why Austin Homeowners Call CleanRun Air Duct Cleaning Austin for Aprilaire Work
We’ve been documenting every duct run with before-and-after photos since 2013. That’s 52,000 homes, every one with a written price before work started. The 365-Day Done Right Promise is backed in writing on every invoice, not mentioned in passing and forgotten.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. They carry Rotobrush, Nikro, and Abatement Technologies equipment, plus Aprilaire-specific fittings and gaskets on the truck. When we pull a camera scope on your Aprilaire system, we’re not guessing at the problem. We’re showing you the photo first, then talking about what needs to happen next.
Tomas Reyes learned this trade in the Bronx Community College HVAC program, then spent years in commercial and residential ductwork across the Northeast before relocating to Austin. He’s crawled through enough Hyde Park attics with original 1990s flex duct to know that what looks fine from the register can be sagging and separated at the plenum. The Austin heat is different, but the principle isn’t: you can’t quote what you haven’t seen.
FAQs
No, independent duct repair and sealing does not void the Aprilaire product warranty, provided the work is performed by a qualified technician and does not alter the unit’s electrical or control components. As an independent Aprilaire service provider, we document every seal and connection so warranty claims on the unit itself remain clean. If your Aprilaire component is still under manufacturer warranty, we note the serial number and installation date before starting work. Call (737) 243-9544 if you need help verifying warranty status.
We stock OEM gaskets, collars, and cabinet seals for current Aprilaire models. For discontinued lines like early 5000-series production, we source quality aftermarket from Guardsman and Honeywell-certified suppliers that match OEM specifications. We document which type we’re using and why on your written scope. If you want strictly OEM on a current model, we can specify that in the quote.
We scope the full system and give you both options in writing. Most Aprilaire-specific issues are localized - a cracked humidifier bypass collar, a separated ERV intake duct - and repairable for under $600. Full duct replacement becomes the honest recommendation when we find multiple disconnected runs, collapsed flex, or rodent damage extending beyond the Aprilaire connection point. The camera shows the difference; we don’t guess.
We schedule within a few business days for non-emergency Aprilaire duct repair and sealing. We do not promise same-day dispatch because duct work requires attic access and proper preparation; rushing it produces sloppy seals. All calls are answered by a live person, 24/7, who can book your camera inspection and written estimate. Call (737) 243-9544 to reserve a slot.
The $79 coupon model typically covers a brief vacuum at the register, not duct repair or sealing. We’ve scoped systems in Austin where the homeowner paid for “duct cleaning” and the plenum was never opened. Our price includes the camera inspection, the written scope, the actual repair, the pressure test, and the documented photo record. Haven Standard Clause 1 means you know the full cost before we start; no per-vent surprises when the truck is in your driveway.
