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 Alexandria: What to Know First
We provide independent Aprilaire duct repair and sealing in Alexandria, with most repairs completed in a single visit and every job starting with a written price before any panel comes off. Our typical turnaround from call to completion is 2-4 business days for standard repairs, and we carry common Aprilaire-compatible parts for the 8140, 8144, and 8145 series ventilators that we see most often in local homes. If you own an Aprilaire whole-house ventilator, dehumidifier, or air cleaner and you’re noticing uneven airflow, whistling at registers, or rising energy bills in your Old Town or Del Ray home, the ductwork connecting that unit to your system is the first place we look. Call (240) 318-7712 for a free written estimate.
How Aprilaire Products Fail - and How We Fix Them
- 8140 Series Whole-House Ventilators: cracked flex-duct collars. The plastic collar where the 8140 meets the main trunk line gets brittle after 6-10 years of Alexandria’s freeze-thaw cycles. We’ve found this exact failure in twelve homes near Eisenhower Avenue since 2023. We replace with a metal-reinforced collar and seal with mastic rated for the temperature swing.
- 8144/8145 Series: sagging return duct runs on second-floor installs. These larger-capacity units move more air, and when the return duct is flex rather than hard pipe, the negative pressure pulls the duct flat against joists in humid summer months. We reinforce with rigid metal elbows at stress points and add support straps every 4 feet.
- 1820/1830 Dehumidifiers: disconnected drain lines causing back-pressure on duct seals. The internal drain pump line works loose, water pools, and the plenum gasket degrades. We reseat the drain, replace the gasket with an OEM-spec part, and pressure-test the seal before closing.
- Model 500 Humidifier: bypass duct corrosion at the furnace connection. The 6-inch round bypass duct on Aprilaire humidifiers rusts through where it meets the furnace cabinet, especially in homes with oversized AC units that short-cycle. We cut back to sound metal, install a stainless sleeve, and seal with high-temp silicone.
- Zone damper integration failures on Aprilaire 6504 panels. When Aprilaire zone panels control dampers in aging duct systems, the sudden pressure changes expose existing leaks. We map the duct system with a pressure pan, seal accessible leaks with mastic, and flag any duct runs that need replacement rather than sealing.
Our Aprilaire Duct Repair & Sealing Process
- 1
Call and scope. You describe the Aprilaire unit model and symptoms. We schedule a diagnostic visit and confirm we’re carrying parts for your series.
- 2
Diagnostic with photo documentation. We pull the access panel, run a borescope through the connected ductwork, and photograph what we find. Haven Standard Clause 1 requires the written price before any repair work begins.
- 3
Parts decision. For Aprilaire ventilators, we use OEM collars and gaskets. For duct material, we match to the existing system, metal or flex, and we tell you which we’re using and why.
- 4
Repair and seal. We replace failed components, seal all joints with mastic (not tape alone), and support flex runs to prevent future sagging.
- 5
Pressure test and photo record. We verify sealed ducts hold pressure, then photograph the completed work. Your documented photo record is delivered before we leave.
- 6
Written guarantee. The 365-Day Done Right Promise goes in writing. If the seal fails or the symptom returns, we make it right.

The duct doesn’t lie - we just show you what’s in it.
FAQs
No. Manufacturer warranties cover the Aprilaire unit itself, not the ductwork connecting it to your system. As an independent Aprilaire service provider, we use warranty-safe practices and document our work so any future unit claim isn’t complicated by our repair. If you’re unsure about your specific warranty status, we can review it during the estimate.
Repair the ducts first if the Aprilaire unit is under 12 years old and the motor still runs quietly. Duct leaks force the unit to work harder and can mimic motor failure. We pressure-test the system before recommending any unit replacement, and we’ll show you the test results.
Every CleanRun job includes a Documented Photo Record of every duct run, before and after, delivered to you before we leave. For Aprilaire ventilator connections, we also pressure-test the sealed joint and record the reading. You’ll see the photo and the number.
We carry common repair parts for the 8140, 8144, 8145, 1820, and 1830 series on our Alexandria trucks. For less common Aprilaire configurations, we source from regional distributors with next-day availability. We’ll tell you before scheduling if your part isn’t in stock.
Most single-component repairs take 2-3 hours. Full zone-system testing and sealing can take a full day. We give you a time estimate in writing with the price, before work starts.
