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.

AfterAbatement Technologies Vent Sanitizing: The Cumming Owner’s Guide
We stock and install Abatement Technologies-compatible vent sanitizing systems in Cumming, with typical installed pricing from $340 to $580 per HVAC system depending on duct configuration and access. Most replacements are completed in a single visit, and we carry the common Abatement Technologies HEPA-CAP and PREDATOR series sanitizing modules on our trucks. Homeowners usually discover the issue after noticing persistent musty odors returning within weeks of a standard duct cleaning, or when their HVAC technician points out visible microbial staining inside the plenum during routine service.
Which Abatement Technologies Models This Applies To
Abatement Technologies produces several vent sanitizing product lines, and matching the correct module matters for both fit and warranty coverage. The HEPA-CAP series (models HEPA-CAP 100, 200, and 400) uses a rectangular mounting bracket with a 10-by-14-inch footprint and integrates directly with the main return-air plenum. The PREDATOR series (600, 800, and 1200 CFM units) employs a cylindrical canister design that seats into a 12-inch duct collar. Both series carry a model label on the upstream face of the housing, usually behind a snap-on inspection panel.
We install OEM Abatement Technologies replacement modules and, where appropriate, quality aftermarket equivalents from Guardsman that meet the same UV-C output and ozone-generation specifications. The aftermarket route typically saves $80 to $140 on parts, though we only recommend it when the existing mounting hardware is in good condition. One compatibility gotcha in Cumming homes: the HEPA-CAP 400 requires a minimum 18-inch straight duct run upstream for proper airflow calibration, and many Vickery subdivision installs fall short by two to three inches due to compact two-story framing. In those cases, we spec the PREDATOR 800 with a custom transition fitting rather than force an improper HEPA-CAP placement.
Signs Your Abatement Technologies Vent Sanitizing Is Failing
- Musty odors return within 30 days of duct cleaning. The UV-C lamp or ozone generator has degraded below effective output. Abatement Technologies lamps typically lose 30% of their germicidal intensity by the 9,000-hour mark, which in Cumming’s cooling-heavy climate translates to roughly 14 to 16 months of runtime.
- Visible dark staining on evaporator coils or duct liner. When sanitizing output drops, microbial colonies reestablish on wet surfaces downstream. The camera showed a 3-inch debris build-up at the first elbow in a Cumming job last March, the direct result of a failed HEPA-CAP 200 lamp that had gone dark six months prior.
- HVAC technician notes “biological growth” during seasonal maintenance. This is often the first professional flag, since homeowners rarely inspect their own plenum. The technician is seeing what the sanitizing system is no longer preventing.
- Unit housing shows corrosion or white mineral deposits. High summer humidity in Forsyth County accelerates galvanic corrosion on the aluminum housing if the internal drain port clogs. This is a separate failure mode from lamp degradation but equally common in our market.
- Indicator light is off or flashing error codes. Abatement Technologies units use a simple LED status: solid green for operational, red for lamp failure, amber for ballast issues. A flashing amber-red sequence on PREDATOR units specifically indicates low airflow, often caused by a clogged pre-filter that owners can check themselves.
BeforeAfterReplacement Cost & What’s Included
| Component | Price Range (Cumming) |
|---|---|
| HEPA-CAP series module (OEM), installed | $340 - $480 |
| PREDATOR series module (OEM), installed | $420 - $580 |
| Aftermarket Guardsman equivalent | $260 - $440 |
| Duct modification / custom transition | $85 - $150 |
| Annual lamp replacement (maintenance) | $120 - $180 |
The range reflects three factors: unit accessibility (attic installs in Cumming’s steeper-pitched neighborhoods add 45 minutes), whether the existing electrical whip and junction box are reusable, and if duct modification is needed for proper airflow. Every quote is delivered in writing before work starts under Haven Standard Clause 1. The 365-Day Done Right Promise covers both parts and labor, and the job record includes before-and-after photos of the plenum interior, the installed unit, and the operational indicator light.
DIY or Call Us?
An owner can safely check three things: the LED status indicator, the pre-filter condition (vacuum or replace if gray/black), and the 120V outlet feeding the unit. What goes wrong past that point is worth understanding. The UV-C lamp operates at high voltage and retains a capacitive charge even when unplugged. Ballast replacement requires matching the exact wattage and strike voltage for the lamp series, and improper pairing either fails to ignite or overdrives the lamp to premature failure. The ozone generator on PREDATOR units, if mishandled, can produce harmful concentrations in an enclosed attic space.
We do not recommend owner replacement of the lamp, ballast, or generator module. The camera doesn’t have an opinion, it just shows you what’s in there, and our documentation starts with exactly that: a photo of your existing unit’s label, the plenum condition, and the electrical connection type. Call (678) 693-5322 and we’ll put a written number next to your situation.
FAQs
How long does an Abatement Technologies vent sanitizing system last in Cumming?
The UV-C lamp requires replacement every 9,000 to 12,000 operating hours, which in this market typically means 14 to 20 months due to extended cooling seasons. The ballast and housing generally last 8 to 12 years unless corrosion from attic humidity intervenes. Call (678) 693-5322 for an exact quote on your unit, estimates are free.
Can the unit be repaired instead of replaced?
Lamp and ballast replacement is technically repair, though we find that by the time a lamp fails, the ballast is often drawing irregular voltage and the housing seals have hardened. Replacing the complete module is usually more cost-effective than sequential component swaps. We also stock parts for Lennox, Trane, and Carrier sanitizing systems if your home has mixed equipment.
How long does the swap take?
Most replacements are completed in 90 to 150 minutes, including documentation photography and operational testing. Attic installations with limited access, common in the older Cumming subdivisions off Bethelview Road, may extend to two and a half hours.
Do you stock Abatement Technologies parts on your truck?
We carry HEPA-CAP 100/200/400 and PREDATOR 600/800 modules, plus Guardsman aftermarket equivalents, on every service vehicle. CleanRun Duct Repair & Cleaning is an independent service provider, not affiliated with Abatement Technologies. Same-day completion is standard when the unit is accessible and no duct modification is required.
