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.
Abatement Technologies Vent Sanitizing: The San Antonio Owner’s Guide
Abatement Technologies vent sanitizing installation in San Antonio typically runs $340-$580 for a whole-system treatment, and we stock the compatible hardware for same-day service on most calls. We match the part to your specific Abatement Technologies unit series, install it under the H.A.V.E.N. Standard, and document the before-and-after condition of every duct run with photographs. Most San Antonio homeowners discover their vent sanitizing has failed when they notice persistent musty odors after the AC cycles off, or when a post-remodel air quality test comes back with elevated microbial counts despite new filters.
Which Abatement Technologies Models This Applies To
Abatement Technologies builds vent sanitizing hardware across several product lines, and the mounting footprint, voltage, and duct diameter compatibility vary enough that swapping between series without verification usually ends in a return trip. We most commonly service the CAP series (CAP600-UV, CAP1200-UV) and the HEPA-Care line with integrated sanitizing modules in San Antonio homes built between 2015 and 2020, particularly in Stone Oak and Alamo Ranch where these units were spec’d by the original HVAC contractors.
To identify your exact part, check the data plate on the sanitizing module itself, not the air handler. The plate lists the model prefix, production date code, and input voltage. CAP-series units use a 120V/1Ph connection with a 6-inch duct collar; HEPA-Care units often run 24V control voltage with a 4-inch or 8-inch collar depending on whether the unit serves a single duct run or a main trunk return. The OEM Abatement Technologies lamp and housing assembly carries a two-year manufacturer warranty, but we also install quality aftermarket equivalents from Lightsources and Atlantic UV that match the UV-C output spec (254 nanometers, 36-55 microwatts per square centimeter at one meter) at a lower parts cost. The aftermarket lamps fit the Abatement Technologies housing without modification on CAP series; HEPA-Care units sometimes need a collar adapter, which we fabricate on-site rather than forcing a fit.
Signs Your Abatement Technologies Vent Sanitizing Is Failing

- Persistent musty or sour odors when the blower starts. The UV-C lamp degrades to roughly 60 percent output after 9,000 hours of runtime, which in San Antonio’s extended cooling season translates to about 14-16 months of actual use. At that threshold, the lamp still glows violet but no longer produces germicidal UV-C, so microbial colonies survive in the plenum and vent the smell through your registers.
- Visible dust accumulation on supply registers within weeks of cleaning. When the sanitizing module fails, biofilm builds on the evaporator coil and inner duct walls. That film traps passing particles that would otherwise stay airborne through the filter, so you see faster debris fallout at the vents.
- Increased allergy symptoms among household members, especially in spring. San Antonio’s mountain cedar and oak pollen loads are already severe; a failed UV module removes one layer of defense against the mold spores and bacteria that collect in damp ductwork after humid summer nights.
- The indicator light on the module is dark or flickering. Abatement Technologies modules use either a green LED (CAP series) or a small viewport glow (HEPA-Care) to confirm lamp operation. A dark indicator usually means lamp failure; flickering suggests ballast degradation, which will destroy a new lamp within weeks if not replaced together.
- Your HVAC technician notes coil fouling during routine maintenance. A clean evaporator coil that develops black or gray biofilm between annual checkups is often the first diagnostic clue we see, since the coil sits downstream of the sanitizing module and loses protection when UV-C output drops.

AfterReplacement Cost & What’s Included
| Component | Price Range (Installed) |
|---|---|
| UV-C lamp only (OEM Abatement Technologies) | $180-$260 |
| UV-C lamp (quality aftermarket equivalent) | $140-$200 |
| Lamp + ballast assembly replacement | $280-$420 |
| Full module replacement (housing, lamp, ballast) | $420-$580 |
| Whole-system sanitizing treatment (per system) | $340-$480 |
What drives the range: whether your unit needs a lamp swap or the full ballast assembly, whether the duct collar size requires custom fabrication, and whether we find secondary issues like a cracked quartz sleeve or corroded mounting bracket during the photo inspection. Every quote is written before work starts under Haven Standard Clause 1, with parts and labor itemized separately. The 365-Day Done Right Promise covers the installation workmanship; OEM lamps carry the manufacturer’s warranty, and our aftermarket equivalents carry a 12-month replacement guarantee.
DIY or Call Us?

What you can safely check yourself: confirm the indicator light status, verify the unit is receiving power at the junction box with a non-contact voltage tester, and inspect the quartz sleeve for visible cracks or mineral scaling. Do not attempt to remove the lamp while powered, and do not look directly at a lit UV-C lamp even briefly. The UV-C wavelength causes flash burns to the cornea with exposure times under a minute.
Where DIY goes wrong: homeowners often replace the lamp without replacing the degraded ballast, which cooks the new lamp in weeks. They also handle the quartz sleeve with bare fingers, leaving skin oils that create hot spots and premature failure. The lamp type matters. Abatement Technologies specifies a low-ozone lamp for residential use; a standard ozone-generating UV lamp will degrade rubber gaskets and create respiratory irritants. We stock both lamp types on our trucks, verify the correct match against your data plate, and handle disposal of the mercury-containing spent lamp under Texas environmental guidelines. Call (726) 600-7155 for a written quote before you buy parts that may not fit.
FAQs
Expect 14-18 months of effective germicidal output given San Antonio’s long cooling season and the 9,000-hour rated lifespan. The lamp may still glow after that point, but UV-C output drops below the threshold that actually kills mold and bacteria. We recommend replacement at 12 months for households with allergy-sensitive members. Call (726) 600-7155 and we’ll check your runtime hours against the install date.
No. UV-C lamps are sealed glass tubes with a finite mercury vapor charge; once depleted, they cannot be recharged or refurbished. The ballast and quartz sleeve can sometimes be cleaned or reseated, but the lamp itself is a consumable part. We inspect all three components during replacement and only quote what actually needs changing. Bring any competitor’s written estimate; our Free Second Opinion puts our itemized number next to it at no cost.
Most Abatement Technologies lamp replacements take 45-90 minutes including photo documentation of the duct run condition before and after. A full module replacement with collar adaptation runs 2-3 hours. We schedule enough time that the crew is not rushing to the next call; the written price does not change if the job runs long. The camera goes in first. Then we talk.
We carry OEM and aftermarket UV-C lamps, ballasts, and quartz sleeves for the CAP and HEPA-Care series on every San Antonio service vehicle, along with collar adapters for the less common 8-inch HEPA-Care returns. For discontinued modules or specialized commercial units, we source overnight from our distributor in Houston. We do not start the job until the correct part is in hand and verified against your data plate.
CleanRun Duct Repair & Cleaning is independently owned and operated under the Haven Standard. We are not affiliated with Abatement Technologies, though we install and service their equipment according to manufacturer specifications using parts customers can verify independently. We also stock parts for Lennox, Trane, and Carrier sanitizing systems.
Ready for a written price before any work starts? Call (726) 600-7155. We’ll match the part to your Abatement Technologies unit, show you the inside of your ductwork on camera, and leave you with a documented photo record of every run, backed by our 365-Day Done Right Promise.
