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.
Guardsman Air Quality & Sanitizing in Cumming: What to Know First
We provide independent Guardsman air quality and sanitizing service in Cumming, with most scheduled jobs completed in a single visit and a written price delivered before any work begins. Typical Guardsman UV light installations and whole-system sanitizing runs range from $340 to $780 depending on the series and how many air handlers are involved. We’re not affiliated with or authorized by Guardsman; we are an independent service provider that documents every duct run with before-and-after photos and backs the work with our 365-Day Done Right Promise.
This page is for Cumming homeowners who have a Guardsman air purifier, UV system, or whole-home sanitizing unit that needs service, replacement, or honest assessment of whether it’s doing anything at all. If you own a Guardsman product and want to know what you’re actually breathing, call us at (678) 693-5322. Tomas Reyes and our crew have worked on Guardsman equipment across Cumming, including plenty of two-story homes in Vickery where the return-air trunk lines collect more debris than owners expect.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GUV-1000 series UV lamps burn out silently. The lamp still glows faintly, so owners assume it’s working. We measure actual UV-C output with a radiometer; if it’s below 40 microwatts per square centimeter at one meter, the lamp is decorative, not functional. We replace with Guardsman-specified 254-nanometer lamps or verified equivalents and show you the reading.
- Guardsman GAP-500 electronic air purifiers develop oxidized collector cells. The aluminum plates corrode in Cumming’s humid summers, especially in homes near Lake Lanier where the moisture load is higher. We remove the cells, photograph the oxidation pattern, and either restore them with a non-acidic degreasing bath or recommend replacement if the metal is pitted.
- Guardsman GAS-3000 whole-home sanitizing systems clog at the injection nozzle. The fine-mist nozzle that distributes sanitizer into the plenum (the main duct box that connects to your air handler) gets blocked by mineral scale from the solution reservoir. We descale with manufacturer-approved citric acid flush, never mechanical drilling, which voids the warranty.
- Guardsman GUV-2000 dual-lamp units suffer ballast failure after 4-6 years. The ballast (the electrical component that fires the lamp) degrades from heat cycling in Cumming’s attic installations. We test ballast output under load; if it’s flickering or below spec, we install an aftermarket ballast that matches OEM electrical characteristics, documented in writing.
- Guardsman GAP-300 media air cleaners bypass dirty filters. When homeowners install the wrong MERV rating or forget to change media, the pressure drop forces unfiltered air around the cartridge through gasket gaps. We inspect the filter track with a borescope, replace gaskets if compressed, and log the correct media part number on your job record for future reference.
Our Guardsman Air Quality & Sanitizing Process

- 1
System identification and written scope. We record the exact Guardsman model, serial number, and installation date, then deliver a written price before touching the unit. Haven Standard Clause 1: no exceptions.
- 2
Diagnostic photography. We run a camera through the plenum and first duct run to document current conditions. The camera doesn’t have an opinion - it just shows you what’s in there.
- 3
Component testing with logged results. UV output, ballast voltage, airflow across the collector cell, and sanitizer flow rate are measured and recorded. You get the numbers, not a verbal “seems fine.”
- 4
Repair or replacement with parts disclosure. We specify OEM Guardsman parts or quality aftermarket equivalents, with the trade-off explained in writing. Warranty-safe practices only.
- 5
Post-service verification and photo record. After work is complete, we re-test, re-photograph, and deliver the documented photo record as a standard deliverable. Haven Standard Clause 6: Verified Completion.
- 6
Written guarantee activation. The 365-Day Done Right Promise is printed, signed, and left with you. If it’s not right, we make it right.

FAQs
No, as long as we use Guardsman-specified parts and follow manufacturer procedures for installation and testing. We document every part number and test result in your job record so warranty claims, if needed, are supported with evidence. Call (678) 693-5322 if you have a specific warranty concern.
You don’t, by looking. A failed UV lamp often still glows with visible light while producing no germicidal UV-C output. We measure with a calibrated radiometer and show you the reading. If it’s below 40 microwatts per square centimeter at one meter, the lamp needs replacement regardless of appearance.
Replace if the unit is over 8 years old and requires ballast or control board work; repair if it’s a lamp, cell, or nozzle issue on a unit under 6 years. We give you both numbers in writing and let the math decide. Our Free Second Opinion applies if you’ve already been told replacement is your only option.
Most scheduled jobs run 2 to 4 hours for a single system, including diagnostic photography, component testing, and the documented photo record. We don’t rush; we log every measurement. You’ll get a time estimate in writing with your price before we start.
The $79 coupon model relies on arriving with a shop vacuum and finding “problems” once the truck is in your driveway. We don’t do that. Our price is flat per system, agreed in writing before work starts, and includes the full documented photo record. The difference is visible in the photos.
