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 Dryer Vent Cleaning in Leesburg: What to Know First
CleanRun provides independent Aprilaire dryer vent cleaning in Leesburg with written prices delivered before any work starts and a documented photo record of every duct run. Most Aprilaire dryer vent jobs we handle in Loudoun County are completed in a single visit, with the inspection camera going in first so you see what we see before agreeing to a scope. We are not affiliated with or authorized by Aprilaire; we are an independent service provider who works on these systems daily in Leesburg homes built between 2015 and 2022, where Aprilaire venting components were commonly spec’d by builders. Call (571) 487-7204 for a free estimate with a written price.
How Aprilaire Products Fail - and How We Fix Them
- Model 6504 and 6510 vent caps with integrated backdraft dampers: The polymer hinge pins on these caps fatigue after three to four Leesburg winters, especially on south-facing exposures where freeze-thaw cycles accelerate plastic embrittlement. The damper either hangs open, letting cold air back into the laundry room, or seizes shut, trapping moist exhaust and tripping the dryer’s high-limit sensor. We replace with a metal-hinged cap rated for Virginia’s temperature swing, or install a bird guard with a stainless-steel flapper if the homeowner wants the added protection.
- Flexible transition ducts in Aprilaire builder packages: Aprilaire’s spec for new construction often includes a UL-listed foil transition duct that kinks at the first 90-degree elbow behind the dryer, particularly in Leesburg’s tighter laundry closets. The kink creates a lint trap that the dryer’s own airflow cannot clear. We replace with a rigid aluminum elbow and short metal transition, measured to the exact depth of your closet, then photograph the before and after from inside the duct run.
- Model 6400 series vent hoods with built-in lint screens: The fine-mesh screen was designed for locations with strict wildlife codes, but in Leesburg’s mixed hardwood-pine environment, the screen clogs with pollen and fine lint within eighteen months. Homeowners who don’t know the screen exists call us for “dryer not heating” when the real problem is airflow starvation. We remove the screen if local code permits, or replace the hood with a louvered design that sheds debris without trapping it.
- Long-run venting in Aprilaire-equipped townhomes near Village at Leesburg: Builders in that development ran 25-foot-plus vent paths through shared framing to reach exterior walls. Aprilaire’s rated static pressure assumes shorter runs, so the dryer labors, the thermal fuse blows, and lint deposits at the low points. We use a rotary brush system with reverse-blast nozzles to clear the full length, then test actual airflow with an anemometer at the cap to verify the fix.
- Model 6200 interior-mounted vent kits in basement laundry rooms: These recirculate moist air through a reservoir, common in Leesburg’s walkout basement builds. The reservoir cracks from mineral buildup if the homeowner uses tap water instead of distilled, or the float switch fails and the unit overflows. We clean the reservoir and duct path, test the float, and document any cracks with photos. If the kit is beyond service, we quote a through-wall vent to exterior, with the price in writing before we cut any holes.
Our Aprilaire Dryer Vent Cleaning Process

- 1
Inspection camera entry: We feed a lighted borescope into the vent from both ends - the cap exterior and the transition behind the dryer - before touching a tool. You see the footage in real time. The camera goes in before the quote comes out.
- 2
Written scope and price: Based on what the camera shows, we deliver a single-page scope with line-item pricing under Haven Standard Clause 1. No verbal estimates, no “we’ll see how it goes.” You sign or decline before work starts.
- 3
Component assessment: If the vent cap, transition, or hood needs replacement, we specify OEM Aprilaire or a quality aftermarket equivalent, with the part number and warranty term noted on the scope. You choose; we don’t default to the most expensive option.
- 4
Mechanical cleaning and extraction: We use Rotobrush rotary tools with nylon or wire bristle heads sized to your duct diameter, paired with Nikro negative-pressure extraction to capture dislodged lint at the source. No shop-vac pushed against a register.
- 5
Post-clean verification: We re-run the camera for the after photos, measure airflow at the cap with a calibrated anemometer, and test the dryer’s exhaust temperature at the wall connection. The photo record and test results go to you by email before we pack up.
- 6
Documentation and guarantee: You receive the before-and-after photo set, the signed scope, and the 365-Day Done Right Promise in writing. If airflow drops or a component we touched fails within a year, we return and make it right.

AfterWhat Aprilaire Dryer Vent Cleaning Costs in Leesburg

Factors that move the price: duct length past 25 feet, roof or attic access required, multiple 90-degree elbows, or discovery of a disconnected joint inside a wall cavity. We find those with the camera first, show you the image, and quote the repair before cutting or drilling. Call (571) 487-7204 for a free estimate with a written price.
Why Leesburg Homeowners Call CleanRun Air Duct Cleaning Leesburg for Aprilaire Work

We’ve cleaned Aprilaire venting in Leesburg since 2013, from the townhomes near Village at Leesburg to the single-family builds around Ida Lee Park where the return grilles haven’t been pulled since the house was built. Tomas Reyes and our crew work under Haven Standard Clause 3: Verified Crews - background-checked, uniformed, identified by name before arrival. We also service Lennox, Trane, and Carrier venting systems, so we recognize when a problem is generic to dryer vent design rather than specific to Aprilaire, and we don’t sell you a brand-specific fix for a universal issue. Every job carries the 365-Day Done Right Promise in writing, the documented photo record, and the equipment roster you can verify: Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman.
FAQs
No. Routine dryer vent cleaning does not void Aprilaire’s product warranty, though damage caused by improper service might. As an independent Aprilaire service provider, we document our methods and use tools rated for residential ductwork, so if a warranty question ever arises, you have a written record of exactly what was done and with what equipment. Call (571) 487-7204 if you need a copy of our service documentation for a warranty claim.
OEM parts match the original specifications exactly; quality aftermarket equivalents often cost 20-30% less and carry comparable warranties. We specify both options on the written scope with part numbers and warranty terms, so you decide based on price and preference, not our default. For vent caps exposed to Leesburg’s freeze-thaw cycles, we typically recommend metal-hinged aftermarket caps over the original polymer design. Call (571) 487-7204 and we’ll show you the difference on the camera.
Replace the run if the duct is galvanized steel with internal corrosion visible on camera, if there are multiple inaccessible leaks inside finished walls, or if the static pressure test shows airflow below 1,000 FPM after cleaning. Repair is sufficient for lint buildup, a failed cap, or a disconnected joint accessible from basement or crawl space. We quote both paths in writing when the camera shows it’s a close call. Call (571) 487-7204 for a free inspection.
Every 12 to 18 months for a typical household of two to four people. Leesburg’s pollen season extends from late March through early June, and we’ve found that fine tree pollen accumulates in vent caps alongside lint, accelerating blockage. Homes with pets, multiple loads per week, or long horizontal runs should schedule annually. We note your vent configuration and recommend a return interval on the job record. Call (571) 487-7204 to schedule or set a reminder.
Yes. We stock common Aprilaire vent caps, transitions, and hoods on our Leesburg-based trucks, and our suppliers in Northern Virginia carry the full catalog with next-day availability for less common items. If we discover a needed part mid-job that we don’t have, we stop, show you the issue, and reschedule at no additional trip charge once the part arrives. We do not improvise with incompatible substitutes. Call (571) 487-7204 to confirm current inventory for your model.
