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.

AfterGuardsman Air Quality & Sanitizing in Leesburg: What to Know First
We provide independent Guardsman air quality and sanitizing service in Leesburg, with most jobs scheduled within a week and completed in a single visit. A typical whole-system treatment runs $340-$780 depending on duct configuration and whether UV or purifier hardware is involved, and we put that price in writing before any panel comes off. This page is for homeowners running Guardsman air purifiers, UV systems, or whole-home sanitizing equipment in Leesburg subdivisions like Belmont Country Club, Lansdowne on the Potomac, or the older ranch homes near Ida Lee Park - anyone who wants to know what failing Guardsman air quality components actually look like and what fixing them costs. Call (571) 487-7204 for a free written estimate.
How Guardsman Products Fail - and How We Fix Them
- Guardsman PureAir 1000/2000 series UV lamps lose output at 9,000-10,000 hours - the quartz sleeve clouds with oxidation, and the 254-nanometer output drops below the 40 microwatts per square centimeter threshold that actually suppresses microbial growth. We meter the actual output, replace the lamp and sleeve as a matched set, and show you the before/after UV intensity reading on the photo record.
- Guardsman APCO-X whole-home purifiers develop oxidizer cell degradation in Leesburg’s hard water zones - the titanium dioxide matrix scales with calcium and iron deposits from the public supply, cutting the photocatalytic reaction rate by half or more. We descale the cell with manufacturer-specified solution or replace it if the substrate is etched, and we document the scaling severity with a close-up frame.
- Guardsman REME-HALO in-duct units suffer from failing ionizer probes in homes with variable-speed blowers - the constant on/off cycling from modulating systems causes arcing at the needle tips, and the plasma output becomes intermittent. We test for consistent ion generation across all blower stages, replace the probe assembly with OEM or equivalent, and verify uniform output before we leave.
- Guardsman carbon media filters in the CMF line saturate faster than rated in Leesburg’s pollen-heavy spring seasons - the Blue Ridge pollen load, particularly oak and hickory, loads the activated carbon with particulates before the chemical adsorption capacity is exhausted. We inspect the media for face-loading versus depth-loading, replace only when actually saturated, and show you the cross-section so you aren’t paying for a filter that still has life.
- Guardsman sanitizer injection systems (SaniGuard series) clog at the nozzle when homeowners run humidifiers above 45% RH - the atomized solution absorbs ambient moisture and crystallizes at the orifice, dropping distribution pressure and leaving duct runs untreated. We pull and clean the nozzle under magnification, set the humidistat recommendation in writing, and photograph the crystallization pattern so you see the cause.
Our Guardsman Air Quality & Sanitizing Process
- 1
Inspection with documentation. We feed a borescope into the plenum (the main duct junction) and each branch run, photographing the current state of your Guardsman equipment and the surrounding ductwork. The camera goes in before the quote comes out.
- 2
Written scope and price. Tomas Reyes or a senior technician delivers a written scope with line-item pricing under Haven Standard Clause 1 - one flat price per system, no per-vent add-ons, valid for 30 days.
- 3
Parts decision with verification. We stock OEM Guardsman lamps, cells, and probes, and we also source quality aftermarket equivalents where the OEM part is back-ordered or discontinued. You see the part number and manufacturer before we open the packaging.
- 4
Service execution with negative-pressure containment. For sanitizing jobs, we seal the return side and run negative-pressure extraction (suction that pulls contaminants out rather than letting them escape into the living space) while applying the treatment. For UV or purifier installs, we verify electrical load at the board and confirm the interlock is wired correctly.
- 5
Post-service testing and photo record. We re-meter UV output, ion concentration, or pressure drop as applicable, photograph the installed or serviced component, and deliver the full record to you before the truck leaves.
- 6
365-Day Done Right Promise activation. The written guarantee goes into effect immediately. If the microbial count rebounds, the odor returns, or the UV meter reading drops, we come back and make it right.

AfterWhat Guardsman Air Quality & Sanitizing Costs in Leesburg
| Service | Typical Range | What Moves the Price |
|---|---|---|
| UV lamp replacement (single lamp, PureAir series) | $180-$290 | Accessibility of the plenum; whether the quartz sleeve is seized |
| APCO-X/REME-HO cell or probe replacement | $260-$440 | OEM versus quality aftermarket; whether the duct liner needs repair around the cut-in |
| Whole-system sanitizing (negative-pressure, no hardware) | $340-$520 | Number of duct runs; presence of visible mold requiring pre-treatment |
| UV purifier new install (Guardsman or cross-brand compatible) | $580-$780 | Electrical run length; whether a dedicated circuit is needed |
| Air purifier + sanitizer combo service | $640-$920 | System tonnage; accessibility of all returns in multi-zone homes |
These are whole-system prices agreed in writing before work starts - no per-vent pricing, no post-arrival upsells. The only add-on we quote separately is duct repair if the inspection finds separated flex duct or deteriorated liner, and we show you the photo before adding it to the scope. Call (571) 487-7204 for a free written estimate on your Guardsman system.
Why Leesburg Homeowners Call CleanRun Air Duct Cleaning Leesburg for Guardsman Work
We’ve been in Leesburg since 2013, and the 365-Day Done Right Promise applies to every Guardsman job we touch - not as a courtesy, but as a written guarantee backed by Haven Standard Clause 5. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they carry Guardsman, Lennox, Trane, and Carrier parts knowledge because most Leesburg homes we see run mixed-brand systems. The documented photo record is standard, not an upgrade. When a Belmont Country Club homeowner called last spring about a persistent musty smell after a competitor’s “sanitizing,” our camera found untreated mold behind a sealed return boot - the other crew had never pulled the register. We treated it, photographed the remediation, and the Done Right Promise covered the follow-up air sample. That’s the difference between a visit and a documented record.
FAQs
No - routine maintenance and compatible part replacement by an independent service provider does not void your Guardsman warranty, provided the work does not damage the unit. We are an independent Guardsman service provider, not an authorized dealer, and we document every step so warranty disputes are traceable. If your unit is under original warranty and needs a factory-authorized repair, we’ll tell you before we touch it. Call (571) 487-7204 and we’ll check your serial number against the warranty period.
We deliver a documented photo record of every duct run before and after treatment, plus a written scope stating what was applied, at what concentration, and for what contact time. For UV installs, you get the meter reading in microwatts per square centimeter. For whole-home sanitizing, we can arrange third-party air sampling at your request - we don’t sell the test ourselves, to avoid the conflict. The 365-Day Done Right Promise means if you smell the problem again, we return. Call (571) 487-7204 to schedule.
The $79-$149 coupon jobs typically run a shop vacuum at the register for twenty minutes, never open the plenum, and never touch your Guardsman hardware. We open every accessible panel, service the equipment that’s actually installed, and photograph the inside of every run. The price difference is the difference between vacuum noise and documented work. We put our written price next to any competitor’s quote for free under our Free Second Opinion - bring it in. Call (571) 487-7204.
Repair makes sense if the unit is under ten years old, parts are available, and the ductwork around it is sound. Replacement is the better call when the chassis is corroded, the model is discontinued with no parts pipeline, or you’re already planning a full system changeout. We stock Guardsman, Honeywell, and Aprilaire hardware and will quote either path in writing with a five-year cost projection. Call (571) 487-7204 for both numbers.
UV lamps need annual output testing and typically replacement every 12-14 months; carbon media every 6-12 months depending on pollen load; and sanitizer nozzles inspected every two years. Leesburg’s combination of Blue Ridge pollen, summer humidity, and hard water from the Potomac aquifer accelerates wear on all three. We don’t sell maintenance contracts - we call you when your equipment is due based on the install date in our records. Call (571) 487-7204 to get on the schedule.
