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 San Antonio: What to Know First
CleanRun Air Duct Cleaning San Antonio provides independent Aprilaire duct repair and sealing services throughout San Antonio, typically completing most jobs in a single scheduled visit with a written price delivered before any panel comes off. We work on Aprilaire whole-home air cleaners, dehumidifiers, and ventilation systems as they connect to existing ductwork, not as an authorized dealer. Our crews carry OEM and quality aftermarket parts for common Aprilaire series including the 1000, 2000, and 5000 lines, and every repair is backed by our 365-Day Done Right Promise in writing.
This page is for San Antonio homeowners who see uneven airflow from their Aprilaire-integrated system, hear whistling at the bypass damper, or have been told their flex duct has separated at the plenum connection. If that’s your situation, call (726) 600-7155 for a free estimate with a written price before work starts.
How Aprilaire Products Fail - and How We Fix Them
- Model 5000 electronic air cleaner: The bypass damper gasket hardens after three to five San Antonio summers, creating a whistle at 400+ CFM that homeowners mistake for a motor problem. We replace the gasket with OEM-spec silicone or upgrade to a solid-state damper if the housing is warped.
- Model 1820/1830 dehumidifier supply tap: The 6-inch flex duct collar cracks where it meets the main trunk in attic installations above 140 degrees. We cut back to sound duct, install a reinforced saddle tap, and seal with mastic rated for the dehumidifier’s static pressure.
- Model 8126X ventilation controller: The barometric bypass can stick partially open, over-pressurizing the return side and blowing out flex duct seams in older Alamo Heights and Monte Vista homes with original 1980s ductboard. We reset the controller, test static pressure across the Aprilaire and the native system, then repair any blown seams with fiberglass mesh and UL-181 mastic.
- Model 1000 media air cleaner cabinet: The sheet-metal cabinet bows at the filter access door when homeowners overtighten the thumb screws, breaking the seal and allowing bypass airflow that deposits dirt downstream. We true the flange, replace distorted hardware, and verify seal integrity with a smoke pencil.
- Model 800 steam humidifier distribution tube: The 1/4-inch copper distribution tube into the ductwork can work loose from thermal cycling in unconditioned San Antonio attics, spraying steam directly onto flex duct inner liners and causing delamination. We secure the tube with a proper strain relief, inspect the liner for heat damage, and replace any compromised flex with R-8 insulated duct rated for the humidifier’s output temperature.
Our Aprilaire Duct Repair & Sealing Process
- 1
Scope with a camera first. We run a borescope through every accessible duct run connected to the Aprilaire component, photographing the plenum connection, any bypass junction, and the full length of flex duct. The camera goes in first. Then we talk.
- 2
Written price on the spot. Using the photo record and static pressure readings, we deliver a single flat price for the complete repair, itemized by line item under Haven Standard Clause 1. No per-vent add-ons, no trip charges buried in fine print.
- 3
Parts decision documented. For Aprilaire-specific components, we note whether we’re installing OEM, a quality aftermarket equivalent, or a field-fabricated solution, and why. The customer initials the parts selection before work proceeds.
- 4
Repair and seal. We execute the repair, seal all joints with mastic or foil tape as appropriate to the pressure class, and reinstall the Aprilaire component with proper clearances for service access.
- 5
Post-repair verification. We re-run the camera to document the finished work, take after photos of every repaired run, and test system static pressure to confirm the Aprilaire is operating within manufacturer spec.
- 6
Deliver the job record. The customer receives the complete photo set, the written scope, and the 365-Day Done Right Promise before the crew packs up.
BeforeAfterWhat Aprilaire Duct Repair & Sealing Costs in San Antonio
Most Aprilaire duct repair and sealing jobs in San Antonio fall between $340 and $890 for a single system, with the final figure depending on what the camera finds and how much duct is involved.
| Scenario | Typical Range |
|---|---|
| Bypass damper gasket or seal replacement (Model 5000 series) | $180 - $340 |
| Flex duct repair at dehumidifier supply tap (Model 1820/1830) | $290 - $520 |
| Multiple seam seals with mastic, full system (ventilation controller overpressure) | $480 - $780 |
| Cabinet reseal and flange true (Model 1000 series) | $240 - $410 |
| Steam distribution tube secure plus flex duct replacement (Model 800) | $560 - $890 |
What moves the price: accessibility (crawl space versus walk-up attic), extent of heat or moisture damage to existing flex, and whether the Aprilaire component itself needs repositioning for proper clearance. We do not quote per-vent or per-register pricing, and we do not offer teaser coupon rates that change once the van is in your driveway. Call (726) 600-7155 for a free estimate with a written, flat price before any work starts.
Why San Antonio Homeowners Call CleanRun Air Duct Cleaning San Antonio for Aprilaire Work
We’ve logged thousands of hours in San Antonio attics since 2013, including tract homes near Stone Oak where flex duct collapses and dust accumulation tend to be textbook examples of what we document on every job. Our crews are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we carry parts for Lennox, Trane, and Carrier systems as well, which matters when the Aprilaire is integrated with a mixed-manufacturer setup common in homes built 2015 to 2025.
Every repair concludes with a Documented Photo Record of every duct run, delivered as a standard deliverable, not an upsell. The 365-Day Done Right Promise is printed on the invoice, not buried in a website footer. And if you have a written estimate from another contractor, we provide a Free Second Opinion at no cost, with our number written next to theirs so you can compare line for line.
FAQs
No, proper duct repair and sealing does not void the Aprilaire equipment warranty, provided the work does not alter the unit’s electrical or control components. As an independent Aprilaire service provider, we document our repair methods and use parts that meet or exceed OEM specifications, so warranty claims on the core unit remain valid. If your Aprilaire is still under warranty, we note the serial number and installation date on our work order for your records. Call (726) 600-7155 if you need help determining warranty status.
OEM parts are required for any component that carries an electrical listing or interfaces with the Aprilaire control board, such as the Model 5000’s power head or the 8126X’s barometric damper motor. For duct-connection hardware, gaskets, and flex duct, quality aftermarket meeting UL-181 standards performs identically at lower cost, and we document the specification on your written scope. We explain the choice before work starts and note it on the invoice. Call (726) 600-7155 for a free estimate with parts details included.
Replace the flex duct run if the inner liner is delaminated, if there are more than two punctures or tears within a six-foot section, or if the insulation is compressed below R-6 value. Repair with fiberglass mesh and mastic is sufficient for isolated seam failures at collars or elbows where the liner and insulation remain intact. We make this call based on what the camera shows, not a rule of thumb, and we show you the photo before recommending either option. Call (726) 600-7155 for an inspection and written recommendation.
Most Aprilaire duct repairs are scheduled within three to five business days of your call, with the work completed in a single visit of two to four hours depending on accessibility and scope. We do not promise same-day dispatch because duct repair requires daylight for safe attic work and proper photo documentation, and we do not rush jobs that involve sealing materials with cure times. You will receive a specific arrival window when you book, and the technician calls thirty minutes before arrival under Haven Standard Clause 2: Confirmed Arrival. Call (726) 600-7155 to check current availability.
You receive a Documented Photo Record showing the inside of every repaired duct run before and after work, plus a written scope listing every seal location and the material used. For San Antonio homeowners who want additional verification, we offer a post-repair static pressure test comparing system performance against manufacturer specifications for your Aprilaire model. The photo record, written scope, and test results are yours to keep. Call (726) 600-7155 to schedule a repair with full documentation.
