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 New Braunfels Owner’s Guide
We stock and install Abatement Technologies-compatible vent sanitizing systems in New Braunfels, with typical installed pricing from $340 to $680 depending on system size and duct configuration. Most residential jobs can be scheduled within 48 hours, and we carry the core Abatement Technologies UV-C and photocatalytic oxidation components on our trucks for the common CAP series units. Homeowners usually discover a problem when the sanitizing indicator light stops cycling, they notice mustiness returning at the registers after a previous cleaning, or their HVAC technician spots a darkened or cracked UV lamp during seasonal maintenance.
Which Abatement Technologies Models This Applies To
Abatement Technologies builds vent sanitizing around two main residential lines: the CAP100-UV and CAP200-PCO series, plus the commercial-grade HEPA-CAP units sometimes found in larger New Braunfels homes near the Hill Country rim. The CAP100 uses a single-ended 16-inch UV-C lamp rated for 9,000 hours; the CAP200 adds a titanium dioxide catalyst grid that degrades faster in high-humidity conditions. To identify your unit, check the service label on the duct-mounted housing, usually found 6 to 12 inches upstream of the air handler plenum, the main distribution box that feeds conditioned air into your duct runs.
We source both OEM Abatement Technologies lamps and quality aftermarket equivalents from U.S. Lighting Group and Atlantic UV. The OEM lamps carry a 12-month pro-rated warranty; the aftermarkets we use match the 254-nanometer output spec and cost 20 to 30 percent less, though the ceramic end caps vary slightly in fit on pre-2019 CAP100 housings. That is a compatibility gotcha we check before quoting: early CAP100 units used a twist-lock ceramic base that cracks if forced with the newer push-fit design.
Signs Your Abatement Technologies Vent Sanitizing Is Failing
- The indicator light is dark or flickering. The UV-C lamp has reached end of life or the ballast, the component that steps up voltage to ignite the lamp, is failing. A dark lamp produces no sanitizing effect regardless of what the wall switch suggests.
- Musty or microbial odors return within weeks of duct cleaning. The photocatalytic surface, the titanium dioxide-coated grid that breaks down organic compounds, has become fouled or the UV intensity has dropped below the 40 microwatts per square centimeter threshold needed for activation.
- Visible cracks or darkening at the lamp ends. The electrodes degrade through normal cycling; in New Braunfels, where systems run heavy cooling loads eight months a year, this wear accelerates compared to cooler climates with shorter seasons.
- HVAC technician notes biological growth on the evaporator coil despite the sanitizer running. The lamp may still illuminate but at reduced output, or the unit was installed downstream of the coil rather than upstream, a placement error that renders it decorative.
- Increased allergy symptoms after the unit previously helped. The catalyst grid has accumulated scale from hard Hill Country water vapor or the lamp wavelength has shifted, a failure mode that requires a spectrometer to confirm but shows up in reduced occupant comfort.
BeforeAfterReplacement Cost & What’s Included
For New Braunfels homes, a complete Abatement Technologies vent sanitizing service runs $340 to $680 installed. The lower end covers a straightforward CAP100 UV lamp swap with housing inspection and contact cleaning; the upper end addresses CAP200 units requiring catalyst grid replacement, ballast testing, and duct-sealing remediation around the mounting collar. Every quote is written before work starts under Haven Standard Clause 1, with no per-vent add-ons or trip charges layered in after.
What the price includes: the lamp or component, labor, a new gasket set for the housing, and a post-installation intensity reading with our UVC meter, documented in your job record. The 365-Day Done Right Promise covers the installation workmanship; OEM lamps carry their manufacturer term, while our aftermarket equivalents include a 24-month replacement guarantee. We also photograph the old component and the new installation for your documented photo record, standard on every visit since 2013.
DIY or Call Us?
A homeowner can safely verify the model number and check whether the indicator light responds to the HVAC fan call, but the actual service involves high-voltage components and UV-C exposure that damages eyes and skin in seconds. The ballast operates at 800 to 1,000 volts, and a cracked lamp can release mercury vapor. We do not recommend DIY replacement.
What you can do: note the lamp color when it attempts to strike, a white-blue flash versus orange, and whether the housing hums, which suggests ballast failure rather than lamp failure. Write both observations down. Then call (830) 549-6847. We will bring the matched part, test the circuit under load, and confirm output with a calibrated meter before we leave. Tomas Reyes handles the quote himself, and the price you approve is the price on the invoice.
FAQs
Rated life is 9,000 hours, roughly 12 months of continuous operation, though many New Braunfels homeowners see 14 to 18 months because newer thermostats cycle the fan less aggressively than older systems. The catalyst grid in CAP200 units typically needs replacement every 3 to 5 years depending on humidity load. Call (830) 549-6847 and we will check your run hours against the installation date to give you a specific remaining-life estimate.
No. UV-C lamps are sealed glass assemblies with exhausted internal chemistry; once output drops below effective levels, the lamp cannot be restored. Ballasts can sometimes be rebuilt, but the labor exceeds replacement cost and the warranty is weaker. We quote lamp-plus-ballast replacement as one flat price per system if both are suspect.
Most residential Abatement Technologies vent sanitizing services take 90 minutes to 2 hours, including housing removal, duct collar inspection, electrical testing, and post-installation verification with our UVC meter. Jobs in older New Braunfels homes with rigid ductwork near the Gruene Historic District sometimes run longer if the original mounting hardware has corroded.
We carry CAP100 and CAP200 lamps, the common ballast assemblies, and gasket sets on every service vehicle. Less common HEPA-CAP components and pre-2019 twist-lock lamps we source same-day from our San Antonio supplier if your model requires them. We verify fit before we quote, not after we arrive.
