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 Leesburg: What to Know First
CleanRun provides independent Aprilaire duct repair and sealing in Leesburg, with most jobs scheduled within a week and completed in a single visit. We deliver a written price before any work starts, and every duct run is photographed before and after. If you own an Aprilaire system and you’re seeing uneven temperatures, rising energy bills, or dust patterns around your registers, the issue is often in the ductwork that connects to your equipment, not the equipment itself. Call (571) 487-7204 for a free estimate with no obligation.
How Aprilaire Products Fail - and How We Fix Them
- Model 8144 and 8145 ventilators with cracked flex-duct connections. The constant heat-cycling in Leesburg’s variable Mid-Atlantic climate fatigues the flex duct where it meets the ventilator housing. We cut back to sound material, install a reinforced collar, and seal with mastic rated for the temperature swing.
- Model 1820 and 1830 dehumidifiers with collapsed return plenums. These units move serious air volume, and when the return plenum (the large duct box that feeds the unit) wasn’t built rigidly enough, it implodes slowly over seasons. We rebuild with galvanized metal, add cross-breaks for stiffness, and photograph the pressure test.
- Model 500 and 600 humidifier bypass ducts that whistle or leak. The 6-inch round bypass is often roughed in too tight against joists, creating a kink that both restricts airflow and splits at the seam. We reroute with proper bend radius, replace the damaged section, and balance the damper so you’re not over-humidifying.
- Model 8900 and 8920W zoning systems with leaking zone dampers. The motorized dampers sit in the ductwork itself, and when the blade seal degrades, conditioned air bleeds into closed zones. We source the correct damper actuator, verify the blade geometry, and test each zone’s airflow independently before we leave.
- Whole-house Aprilaire media air cleaners with poorly sealed filter racks. The 20×25 or 16×25 filter cabinet is only as good as its gasketing. We find bypass gaps where unfiltered air is sneaking around the media, replace the compression gasket, and verify with a smoke pencil that every cubic foot is passing through the filter.
Our Aprilaire Duct Repair & Sealing Process
- 1
Inspection with photo documentation. The camera goes in before the quote comes out. We run a borescope through every accessible duct run and show you what we found before naming a price.
- 2
Written scope and price. Haven Standard Clause 1: written price delivered before any work starts. No exceptions. You get the full scope, the parts list, and the total.
- 3
Parts decision: OEM or verified aftermarket. For Aprilaire-specific components like zone dampers or ventilator collars, we use OEM when it protects your warranty. For standard duct materials, we use trade-grade equivalents from Abatement Technologies or Guardsman that match or exceed spec.
- 4
Repair and seal. We fix the mechanical issue first, then seal with mastic or foil-backed tape as appropriate. Metal gets sealed. Flex gets supported. Insulation gets replaced where it’s compressed or moisture-damaged.
- 5
Pressure and airflow verification. We test static pressure at the unit and airflow at the registers, comparing against the manufacturer’s spec sheet for your Aprilaire model.
- 6
Photo record delivery and warranty activation. You receive before-and-after photos of every duct run we touched, plus the written 365-Day Done Right Promise.

Why Leesburg Homeowners Call CleanRun Air Duct Cleaning Leesburg for Aprilaire Work
We’ve been in Leesburg since 2013, and the homes near Ida Lee Park built between 2015 and 2020 are now hitting the age where their original flex duct and plenum seals start to go. Tomas Reyes and our crew have handled enough Aprilaire ventilators and zoning systems to know which model years had the collar design that cracks, and which dehumidifier plenums were undersized by the builder.
Every job carries the 365-Day Done Right Promise in writing, not as a verbal assurance. Haven Standard Clause 3 means verified, background-checked, uniformed technicians who identify themselves by name before they enter your home. And if you’ve already got a written estimate from another contractor, we’ll provide a free second opinion, line item by line item.
FAQs
No, if the work is performed by a qualified technician using correct parts. As an independent Aprilaire service provider, we use OEM components for warranty-sensitive items like zone dampers and ventilator collars, and we document the part numbers in your job record. Call (571) 487-7204 if you need us to review what’s covered under your specific model’s terms.
You receive a Documented Photo Record of every duct run we accessed, before and after, as a standard deliverable on every visit. We also provide static pressure readings from your Aprilaire unit. If a contractor won’t show you the inside of your ducts, you’re buying a promise, not a service.
Replace when the ductwork is galvanized metal with widespread corrosion, or when flex duct has multiple failed sections exceeding about 40% of the total run length. Repair when the issue is localized: a cracked collar, a failed damper, a leaking seam. We’ll tell you which category you’re in, with photos, before you commit to either path.
Most single-component repairs, like a zone damper or humidifier bypass duct, are completed in two to four hours. Whole-system mastic sealing for an average Leesburg home takes a full day. We schedule the arrival window, not a vague “sometime morning” window, and we call when we’re thirty minutes out.
Yes. We stock common Aprilaire dampers, collars, and gaskets, and we source same-day or next-day for less common items. If your system is one of the older 8000-series zone panels, we’ll verify compatibility with current production before we quote, so you’re not paying for a part that doesn’t fit.
