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 Alexandria: What to Know First
CleanRun provides independent Aprilaire air quality and sanitizing services in Alexandria, with most scheduled jobs completed in a single visit and a written price delivered before any panel comes off. Typical whole-system sanitizing runs $380-$720 for Alexandria homes, depending on system size and whether we’re treating mold, bacteria, or odor at the source. This page is for homeowners who already own an Aprilaire air purifier, humidifier, or ventilation system and need someone who knows the difference between a Model 5000 and a Model 1210 without reading the manual in your basement. Call (240) 318-7712 for a free written estimate.
How Aprilaire Products Fail - and How We Fix Them
- Model 5000 Electronic Air Cleaner - ionizing wire corrosion. The tungsten wires in Alexandria’s older 5000 units corrode faster than the manufacturer spec suggests, especially in homes near the Potomac where summer humidity hangs above 70% for weeks. We see arcing gaps and reduced particulate capture that the homeowner notices as more dust on furniture, not as a “broken” unit. Our fix: replace the wire set with OEM Aprilaire parts, clean the ionizing field with a non-conductive solvent, and photograph the before/after on the collector plates so you can see the 0.3-micron difference.
- Model 600 / 700 Series Humidifiers - pad frame mold and scale. These bypass and fan-powered units sit dark and wet through Alexandria’s shoulder seasons, and the evaporator pad frame becomes a mold vector that blows right past the humidistat setting. We treat the pad chamber with a botanical antimicrobial (not a bleach wipe that corrodes the float), replace the distribution tray if it’s scaled from Fairfax County’s moderately hard water, and document the mold species found on the pad if it’s been more than two seasons since service.
- Model 1210 / 2210 / 3210 Media Air Cleaners - collapsed pleats from负压 (negative pressure). The MERV 16 media in these cabinets is dense; when an Alexandria contractor installs one on an undersized return, the pleats suck inward and bypass unfiltered air at the frame edges. We measure static pressure across the cabinet, and if it’s above 0.5″ wc, we flag the duct sizing issue before swapping the media. Otherwise you’re buying $85 filters every eight months to treat a symptom.
- Model 8140 / 8145 Ventilators - stale intake from blocked intake hoods. These whole-house ventilators pull outside air through a hood that gets clogged with pollen, river silt, and the cottonwood fluff that blankets Del Ray every May. The unit runs but the air doesn’t move; we find CO2 levels above 1,000 ppm in bedrooms because the ventilator is circulating attic air, not fresh. Our protocol: remove and photograph the intake hood obstruction, sanitize the intake duct with a fogger, and test the damper operation with a manometer.
- Model 95 / 99 Steam Humidifiers - electrode chamber deliming neglect. These steam units throw a “Service” light when the electrodes scale up, but Alexandria homeowners often miss the early sign: a white dust film on dark furniture near the supply register. The deliming procedure requires draining the canister and running a citric acid cycle - not a vinegar soak that voids the warranty. We perform the full OEM deliming, replace the canister if the electrodes are eroded past 3/16″, and show you the scale volume we flushed out.
Our Aprilaire Air Quality & Sanitizing Process

- 1
Written estimate on arrival. We inspect the Aprilaire unit, measure static pressure if it’s an air cleaner, and deliver a written price before touching a screw. Haven Standard Clause 1.
- 2
Photo documentation of condition. The access panel comes off, the camera goes in. You’ll see the mold on the humidifier pad, the scale in the steam canister, or the collapsed pleats in the media cabinet before we describe what needs to happen.
- 3
OEM or verified-equivalent parts decision. For electronic air cleaners, we stock Aprilaire ionizing wires and collector cells. For media cabinets, we use Aprilaire OEM media or Guardsman MERV 16 equivalent - your choice, with the warranty implications explained in writing.
- 4
Sanitizing or repair execution. Negative-pressure extraction for duct-connected units; botanical antimicrobial fogging for mold or bacteria; UV-C lamp installation if the plenum geometry supports effective dwell time. Every duct run is photographed before and after.
- 5
Operational test and photo record delivery. We verify airflow, check the humidistat or air cleaner indicator, and deliver your Documented Photo Record before the crew packs up. The 365-Day Done Right Promise is in writing on every invoice.

Why Alexandria Homeowners Call CleanRun Duct Cleaning Alexandria for Aprilaire Work

We’ve serviced Aprilaire equipment in Alexandria since 2013, including the colonial-era homes near Del Ray where flex duct gets pinched in ways that would surprise most homeowners. Tomas Reyes and our crew know the difference between a Model 5000 arcing wire and a failing door interlock - and we photograph what’s actually inside before recommending anything. Every job carries the 365-Day Done Right Promise in writing, not as a phone-menu policy. We’re also equipped for Lennox, Trane, and Carrier systems when your home has mixed-brand equipment, which matters in Alexandria’s 2015-2025 builds where the builder spec’d one brand and the homeowner upgraded another. Haven Standard Clause 3: Verified Crews means background-checked, uniformed technicians identified by name before arrival. The duct doesn’t lie - we just show you what’s in it.
FAQs
No, if done with manufacturer-approved methods. We use botanical antimicrobials and citric acid deliming cycles that meet Aprilaire’s service guidelines; bleach-based cleaners and vinegar soaks are what actually void the coverage. If your unit is under warranty, we document our procedure on the invoice so you have a record. Call (240) 318-7712 and we’ll verify your warranty status before scheduling.
Check the performance indicator light - solid green means the ionizing field is active; flickering or red means reduced efficiency or failure. We also measure static pressure drop across the cabinet and photograph the collector plates; a clean plate with no carbon tracking is the real proof. If you’re seeing more dust on furniture six months after a filter change, the unit likely needs service, not just a new media insert.
Repair if the cabinet and blower are sound and parts are available; replace if the unit is pre-2010 and you’re facing a second major repair in two years. The Model 5000, for example, has a 20-year cabinet design life but electronic components that fail predictably after 12-15 years. We give you both numbers in writing - repair cost and replacement cost - so you’re not guessing. Our Free Second Opinion applies to replacement quotes from other contractors too.
Most residential jobs are completed in 2-4 hours, depending on whether we’re treating a single humidifier or a whole-house system with duct fogging. We don’t rush the antimicrobial dwell time - it needs 15 minutes minimum to be effective - and we won’t leave until the operational test confirms airflow and control response. You’ll get the Documented Photo Record before we pack up.
We stock ionizing wires, collector cells, evaporator pads, and steam canisters for the most common Alexandria-installed models - 5000, 600, 700, 1210, and 8140 series. For older or specialized parts, we source from Aprilaire’s Midwest distribution center with typical 2-3 day turnaround. If your job requires a part order, we give you the option to schedule now or wait; either way, the written price doesn’t change when the part arrives.
