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 Alpharetta: What to Know First
We provide independent Guardsman air quality and sanitizing service in Alpharetta, with most residential jobs scheduled within a week and completed in a single visit. A typical whole-system treatment runs $340-$620, and we put that price in writing before any panel comes off. This page is for Guardsman owners in Alpharetta who have noticed persistent odors, elevated allergy symptoms, or visible microbial growth around registers and want to know what their system actually needs, not what a coupon promises. Call (678) 679-7540 for a free estimate with a written scope.
How Guardsman Products Fail - and How We Fix Them
- Guardsman UV Series GUV-8 lamps lose effective output after 9,000 hours without triggering a status fault. The lamp still glows, but the 254 nm germicidal wavelength drops below the 40 µW/cm² threshold needed to neutralize coil-adjacent microbial growth. We meter the actual output at the plenum (the main distribution box where all duct runs connect) and replace only when the reading confirms degradation, not by the calendar.
- Guardsman APCO-X whole-home purifiers develop oxidizer-cell fouling in Alpharetta’s pollen-heavy springs. The EverCarbon cells in these units saturate faster here than in drier climates because March through May brings oak and pine pollen counts that coat the catalyst surface. We pull the cell, photograph the fouling pattern, and either restore it through controlled thermal reactivation or replace it with an OEM-spec cell, depending on what the photo record shows.
- Guardsman REME HALO in-duct units produce ozone drift above 0.05 ppm when the ionization probe corrodes. This happens most often in homes near the Chattahoochee where summer humidity stays above 75% for weeks. We test ambient ozone at multiple registers, replace the probe with a factory-calibrated assembly, and re-test before leaving.
- Guardsman PURE-Flow media filters collapse their MERV-13 pleats prematurely when used on undersized returns. The pressure drop across a loaded PURE-Flow 20x25x5 can exceed 0.5 inches w.c., straining the blower motor and pulling unfiltered bypass air through gasket gaps. We measure static pressure across the filter bank, and if the return is undersized, we document it and quote a duct modification rather than sell you a filter that will fail again in three months.
- Guardsman MicroPure MX4 stick-style purifiers lose their active coating if cleaned with standard HVAC detergents. The titanium-dioxide surface strips under alkaline cleaners, leaving a $400 component inert. Our crews know to use only manufacturer-specified neutral-pH solutions on these units, and we note the cleaning agent in the written job record so the next technician does not undo the work.
Our Guardsman Air Quality & Sanitizing Process
- 1
Call and schedule. A live person answers, confirms your Guardsman model if you know it, and books a diagnostic window. No deposit, no “dispatch fee.”
- 2
On-site diagnostic with photo documentation. The technician introduces themselves by name, then inserts a borescope camera into each duct run. The camera goes in first. Everything else follows from what it shows.
- 3
Written scope and price. Haven Standard Clause 1: we deliver a written price before any work starts. This includes OEM versus quality aftermarket parts options for Guardsman components, with the trade-offs explained.
- 4
Treatment execution. Negative-pressure extraction of debris, application of Guardsman-compatible sanitizing agents, UV or purifier service as scoped, and replacement of any degraded components.
- 5
Post-treatment verification. We photograph every treated duct run after completion, test airflow and static pressure where relevant, and leave you with the photo record and written warranty.
- 6
365-Day Done Right Promise activation. The written guarantee goes into effect immediately. If the odor returns, the microbial growth recurs, or the purifier output drops, we make it right.

AfterWhat Guardsman Air Quality & Sanitizing Costs in Alpharetta
| Service | Typical Range | What Moves the Price |
|---|---|---|
| UV lamp replacement (Guardsman GUV series) | $180-$290 | Single vs. dual-lamp plenum; access difficulty in attic systems |
| APCO-X / REME HALO cell or probe service | $240-$420 | Cell restoration vs. replacement; ozone testing required |
| Whole-system sanitizing with negative-pressure extraction | $340-$620 | Number of duct runs, presence of flex duct, contamination severity |
| Air purifier installation (new Guardsman unit) | $680-$1,400 | Electrical run length, plenum modification, single vs. multi-zone |
These are whole-system prices, not per-vent teasers. We do not quote $79 and find $800 of “discovered problems” in your attic. Call (678) 679-7540 for an exact written estimate - estimates are free, and we will put our number next to any competitor’s written quote under our Free Second Opinion policy.
Why Alpharetta Homeowners Call CleanRun Air Duct Cleaning Alpharetta for Guardsman Work
We are independently owned and operated, not a franchise, and we have documented 52,000+ homes since 2013 with the same practice: camera in, written price, photo record out. Our crews carry Guardsman, Lennox, Trane, and Carrier parts knowledge because Alpharetta homes rarely contain just one brand - your air handler might be Carrier while your purifier is Guardsman, and we service both without calling a second contractor. Tomas Reyes, our owner, put in years on systems throughout Alpharetta including the Avalon area, where construction debris in new-build ductwork remains a recurring source of contamination he still points out to homeowners. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is in writing on every job, not a phone script.
FAQs
No. As an independent Guardsman service provider, we use OEM-spec or manufacturer-approved replacement components and document serial numbers and installation dates in your job record, which satisfies warranty requirements. We are not affiliated with or authorized by Guardsman, but our practices align with their published service standards. Call (678) 679-7540 if you need warranty documentation from a completed job.
The low quote typically omits the negative-pressure extraction step, uses non-OEM lamps without disclosing the shorter lifespan, or quotes a per-vent rate that balloons once the crew arrives. We quote one flat price per system agreed before work starts, with the scope in writing. Bring their written estimate; we will put ours next to it for free under our Second Opinion policy.
You receive a Documented Photo Record of every duct run, before and after, plus a written summary of particulate measurements and any microbial growth observed. If we installed or serviced a UV or purifier unit, we include the output test readings. The evidence is in the job record, not our assurance.
Replace if the unit is more than eight years old and requires a major component - the cost of OEM parts plus labor often approaches a new unit with a fresh warranty. Repair if the failure is isolated to a lamp, cell, or probe and the housing integrity is sound. We give you both numbers in writing and let the math decide.
UV lamps annually, filter media every six to twelve months depending on the home’s particle load, and full system sanitizing every three to five years - sooner if you have completed renovation, noticed persistent odors, or seen allergy symptoms spike. Alpharetta’s heavy spring pollen and humid summers accelerate fouling compared to drier climates.
