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.

AfterHoneywell Air Quality & Sanitizing in Leesburg: What to Know First
We provide independent Honeywell air quality and sanitizing in Leesburg, VA, with most jobs completed in a single scheduled visit and a written price delivered before any panel comes off. Typical whole-system sanitizing runs between $380 and $620 for Leesburg homes, depending on system size and whether we’re treating mold, bacteria, or installing UV light hardware. This page is for homeowners running Honeywell whole-home purifiers, UV systems, or media air cleaners who want the work done warranty-safe and documented.
Call (571) 487-7204 for a free estimate. We’ll put our written number next to any competitor’s quote under Haven Standard Clause 2: Free Second Opinion.
How Honeywell Products Fail - and How We Fix Them
- UV2400U and UV100 series lamp degradation. The 16-inch and 18-inch germicidal lamps in these whole-home UV systems lose output after 9,000 hours whether the blue glow is visible or not. Homeowners notice musty return-air smell returning mid-season. We measure actual UV-C output with a radiometer, replace with OEM-spec lamps or verified-equivalent Phillips TUV lamps, and photograph the quartz sleeve condition - cracked sleeves get swapped, since a cracked sleeve drops effective dose by 60 percent.
- TrueCLEAN Enhanced Air Cleaner (FH8000A) airflow restriction. The 4-inch MERV 15 media in these cabinet units loads fast in Leesburg’s pollen-heavy spring, especially on homes near the Potomac tributaries where cottonwood is dense. Restricted airflow trips pressure switches or strains the blower. We pull static pressure readings at the cabinet, show the customer the loaded media against a clean reference, and source Honeywell FC40R replacement kits or equivalent Filtration Group media - never a 1-inch hack-in.
- F100 and F200 media air cleaner bypass leakage. The snap-lock doors on these bypass units warp slightly after repeated summer humidity cycles common to Loudoun County basements. Unfiltered air leaks around the door seal, carrying basement mildew spores into supply ducts. We realign or replace the door assembly, verify seal with a smoke pencil, and document the before-and-after leakage rate in the photo record.
- DR90 and DR120 dehumidifier coil mold in encapsulated crawl spaces. These whole-home dehumidifiers run hard in Leesburg’s clay-heavy neighborhoods like Lansdowne and Belmont Country Club where ground moisture wicks through foundation walls. Coil mold reduces latent capacity and distributes spores through dedicated duct runs. We treat the coil with EPA-registered sanitizer, install a secondary UV-C lamp at the coil face if the unit lacks factory UV, and photograph the coil condition before and after treatment.
- Zone board damper actuator failure in Honeywell HZ432 and TrueZONE panels. Stuck dampers create dead zones that go untreated by air quality equipment, or over-condition spaces where mold then propagates on cold duct surfaces. We test each damper with the board’s manual override, replace failed actuators with Honeywell M847D or verified Belimo equivalents, and verify zone balance with a digital manometer before signing off.
Our Honeywell Air Quality & Sanitizing Process
- 1
Inspection and documentation. The camera goes in before the quote comes out. We feed a borescope through each duct run, photograph debris load, mold staining, or UV lamp sleeve condition, and note the Honeywell model and serial for parts verification.
- 2
Written scope and price. Haven Standard Clause 1: we deliver a written price before any work starts. The scope names each Honeywell part by model number, specifies OEM or quality aftermarket, and lists the sanitizing agent or UV lamp spec.
- 3
System isolation and protection. We seal registers, establish negative-pressure extraction at the air handler (suction that pulls contaminants out rather than letting them escape into the home), and cover electronic components in the Honeywell control board to prevent moisture damage.
- 4
Treatment or installation. Sanitizing jobs get EPA-registered application at the coil, plenum, and each duct run. UV installations get lamp positioning per Honeywell’s mounting guidelines to avoid ozone generation in occupied spaces. Parts swaps use torque-spec fasteners, not impact drivers.
- 5
Verification and photo record. We re-run the borescope, capture after photos of every treated run, test UV output or static pressure as applicable, and deliver the full photo record with the invoice. The 365-Day Done Right Promise is printed on both.
- 6
Cleanup and walkthrough. Technicians leave the work area photographed, not just “clean.” The customer reviews the photo record on a tablet before signing, and the written warranty activates.

Why Leesburg Homeowners Call CleanRun Duct Repair & Cleaning for Honeywell Work
We’ve been in Leesburg homes since 2013, and the Honeywell equipment we see most often was installed by builders during the 2015-2020 construction surge in neighborhoods like Lansdowne, Woodlea, and along the Route 15 corridor. Tomas Reyes and our technicians know the difference between a UV100A1059 and a UV2400U5000 without pulling out a phone, and we stock the lamps and media that fail most often in this climate.
Every job carries the 365-Day Done Right Promise in writing, not as a verbal assurance. Every duct run is photographed before and after. Our crews are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so multi-brand homes get consistent documentation across equipment types.
CleanRun is independently owned and operated - not a franchise - and our license number is published on every estimate. The photo record, the written price, and the written warranty are standard deliverables on every visit, not upgrades.
FAQs
No, when performed by a qualified technician using manufacturer-compatible parts and EPA-registered agents. We document every step with photos and part numbers, which protects your warranty if a future claim arises. As an independent Honeywell service provider, we follow Honeywell’s published installation and maintenance guidelines; we are not affiliated with or authorized by Honeywell. Call (571) 487-7204 if you have a specific warranty concern - we’ll review your model’s documentation before scheduling.
You receive a Documented Photo Record of every duct run, showing the before condition, the treatment application, and the after result. For UV jobs, we include the radiometer reading. For coil treatments, you get the coil photo before and after. This is standard on every CleanRun job, not an add-on. If a company won’t show you what they found, they didn’t find anything worth photographing.
Most Honeywell media cabinets and UV systems are worth repairing if the housing is intact and parts remain available. The FH8000A and F200 series have 15-plus year housings; the failure point is usually the media or a door seal, not the cabinet. We recommend replacement only when the cabinet is rusted through, the control board is obsolete, or repair costs exceed 60 percent of a comparable new unit. We’ll put both numbers in writing and let you decide.
Rated life is 9,000 hours, or roughly one year of continuous operation. In Leesburg, where UV systems often run April through October, that’s 18-24 months of calendar time before output drops below effective germicidal levels. The blue glow means the lamp is on; it does not mean the lamp is still producing sufficient UV-C. We measure output with a radiometer and show you the reading - no guesswork.
We don’t offer coupon pricing. What we offer is a written price before work starts and a photo record proving the work happened. The $79-$129 sanitizing specials we see in Loudoun County typically cover a single register spray with a consumer-grade fogger, not whole-system treatment. Bring us any written estimate; under Haven Standard Clause 2, we’ll put our scope and price next to it so you can compare actual deliverables.
