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 Air Quality & Sanitizing in Ashburn: What to Know First
CleanRun provides independent Aprilaire air quality and sanitizing service in Ashburn, with most scheduled jobs completed in a single visit and a written price delivered before any work begins. A typical whole-system sanitizing job for an Aprilaire-equipped home runs $380-$620 depending on system size and whether UV light installation or mold treatment is needed. We are not affiliated with or authorized by Aprilaire; we are an independent service provider that documents every duct run with before-and-after photos and backs every job with our 365-Day Done Right Promise.
This page is for Ashburn homeowners who own an Aprilaire air purifier, whole-home dehumidifier, or ventilation system and need documented sanitizing, odor removal, allergen reduction, or UV light installation. If you’re comparing quotes or trying to verify whether your last service actually cleaned what you paid for, the photo record we deliver answers that question directly. Call (240) 771-1508 for a written estimate at no charge.
How Aprilaire Products Fail - and How We Fix Them
- Model 5000 Electronic Air Cleaner: The ionizing wires and collection cells in Ashburn’s hard-water zone accumulate mineral scale faster than in softer-water markets, which reduces ionization efficiency and lets finer particles bypass the unit. We remove the cells, photograph the scale pattern, and sanitize with a pH-neutral cleaner that won’t etch the aluminum - then test ionization current with a microammeter before reassembly.
- Model 800 Steam Humidifier: Electrode chambers in Ashburn develop calcium bridging between electrodes because Loudoun County water runs moderately hard. The unit throws a “Service” light and produces less steam than rated. We descale the chamber or replace it with an OEM Aprilaire 80 canister if the electrode coating is degraded, then verify steam output with a humidity rise test at the return air plenum - the large duct that pulls air back to your furnace.
- Model 1850/1870 Whole-Home Dehumidifiers: The condensate drain line traps biofilm in summer when basement humidity stays above 60% for weeks at a stretch. The result is a musty odor that the homeowner blames on “the basement” when it’s actually the dehumidifier’s drain pan and coil. We pull the coil housing, photograph the biofilm layer, treat with a foaming sanitizer, and install a drain line trap primer if the existing P-trap is drying out.
- Model 1210/2210/3210 Media Air Cleaners: The MERV 13 media cabinet is often installed with an undersized return duct in Ashburn townhomes built 2015-2020, which causes the media to load unevenly and allows bypass air around the filter frame. We find this during camera inspection: one side of the media is black, the other is still white. The fix is sealing the filter track with gasket tape and, in some cases, modifying the return duct transition for even face velocity.
- Model 8140/8144 Ventilators: The enthalpy wheel in these energy-recovery ventilators binds with pollen and construction dust, especially in newer Ashburn subdivisions where landscaping kicked up fine debris for the first two years after build-out. The wheel squeaks, airflow drops, and fresh air intake falls below ASHRAE 62.2 standards. We remove the wheel, clean it with compressed air and a soft brush, sanitize the cabinet, and verify balanced airflow with a manometer - a pressure gauge that measures duct static in inches of water column.
Our Aprilaire Air Quality & Sanitizing Process

- 1
Written price first. We inspect the Aprilaire unit, check the ductwork with a borescope camera, and deliver a written scope and price before any panel comes off. Haven Standard Clause 1: no exceptions.
- 2
Photo documentation of condition. Tomas Reyes photographs every return air plenum before touching a single screw - not as a sales move, but because he’d rather argue from a picture than from a conversation. The customer receives these photos as part of the standard job record.
- 3
Parts decision with full disclosure. For electrode canisters, media, and UV lamps, we stock OEM Aprilaire and quality aftermarket equivalents. We name the manufacturer on the written scope, note any warranty implications, and let the homeowner choose. No part is installed without written approval.
- 4
Sanitizing or repair with negative-pressure containment. For mold treatment or bacteria sanitizing, we seal the duct run and apply EPA-registered sanitizer under negative-pressure extraction - a vacuum setup that pulls airborne particles out of the home rather than letting them settle in living spaces.
- 5
Post-work test and photo record. We verify airflow, humidity change, or particle count improvement depending on the service, then photograph every completed duct run. The customer receives the full photo record and written warranty before the crew leaves.
- 6
365-Day Done Right Promise activation. The written guarantee goes into effect immediately. If the work is not right, we make it right - not as a favor, but as a documented obligation.

These are whole-system prices, not per-vent teaser rates that balloon once the truck arrives. Every estimate is free, every price is written, and every job includes the documented photo record. Call (240) 771-1508 for an exact quote on your Aprilaire system.
Why Ashburn Homeowners Call CleanRun Air Duct Cleaning Ashburn for Aprilaire Work

We’ve logged hundreds of jobs in Ashburn, including properties near the Loudoun Station development, where newer construction and high-density townhomes trap more construction-phase debris than homeowners expect. Our crew knows the difference between an Aprilaire Model 5000 with scaled ionizing wires and one with a failed power supply - two problems that look similar on the thermostat display but require entirely different fixes.
We also service Lennox, Trane, and Carrier systems, which matters when your Aprilaire unit is integrated with a mixed-brand HVAC setup that other technicians won’t touch without a subcontractor. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise, the documented photo record, and the written price before work starts apply to every job, not just the ones that go smoothly.
FAQs
No, provided the work is done with Aprilaire-compatible parts and EPA-registered cleaners. As an independent Aprilaire service provider, we document every product used and every step taken so warranty claims remain valid. If we find a defect that should be covered under Aprilaire’s original warranty, we flag it in writing and advise you on the OEM claim process. Call (240) 771-1508 if you’ve received conflicting information from another contractor.
You receive a documented photo record of every duct run, before and after, as a standard deliverable - not upon request, and not as an upsell. The photo record is date-stamped and shows the interior surface condition of each duct run, the Aprilaire unit’s internal components, and any replaced parts with their packaging visible. If a contractor won’t show you photos of your own ducts, you’re buying a promise, not a service.
Replace if the repair exceeds 50% of a new unit’s installed cost, if parts are obsolete (some pre-2010 electronic air cleaners fall in this category), or if the unit was undersized for your home from the start. Repair if the failure is isolated to a replaceable component - electrode canister, media, UV lamp, or drain line - and the cabinet and fan are sound. We put both numbers in writing under our Free Second Opinion policy so you can compare without pressure.
Most residential UV lamp installations in Ashburn are completed in 90 minutes to two hours, including electrical routing from the furnace board, lamp placement for maximum coil exposure, and post-installation airflow verification. We do not quote “as fast as 30 minutes” - that figure describes a bulb swap in an existing UV fixture, not a proper installation with electrical safety checks.
The $79-$149 offers typically cover a single register vacuuming and a spray of deodorizer, not whole-system sanitizing with negative-pressure extraction. Ask any competitor to specify in writing: how many duct runs are included, whether the Aprilaire unit itself is opened and cleaned, what sanitizer is used, and whether photos are provided. The difference between a coupon visit and our documented service is visible in the photo record - we’ll show you the before photo first, then we can talk about what happens next.
