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 Schertz Owner’s Guide
We stock and install Abatement Technologies-compatible vent sanitizing systems for Schertz homeowners, with typical installed pricing between $340 and $680 depending on the number of supply runs and whether the plenum requires access. Most Abatement Technologies PREDATOR 750, CAP600, or HEPA-AIRE units we see in Schertz can be retrofitted with a vent sanitizing module same-day, since we carry the common coupling sizes and UV-C lamp housing dimensions on our trucks. Homeowners usually discover the issue after a routine duct cleaning, when the borescope camera shows microbial staining on the interior of supply trunks that the standard negative-pressure extraction didn’t remove, or when someone in the home has recurring respiratory irritation that tracks with the HVAC cycle.
Which Abatement Technologies Models This Applies To
Abatement Technologies builds several product lines that accept vent sanitizing add-ons, and the compatibility question is more specific than most homeowners expect. The PREDATOR 750-series portable air scrubbers use a 6-inch duct collar that matches our standard UV-C injection modules, but the older 700-series (pre-2019) uses a 5-inch collar that requires a reducing boot we fabricate on-site. The CAP600-C and CAP600-UV cabinet units have a dedicated lamp housing already, so what we’re typically adding is a secondary distribution manifold to push sanitizer through the duct runs rather than just at the unit itself. The HEPA-AIRE SAH2 and PAS2400 negative air machines don’t accept inline sanitizing directly; for those, we install a separate bypass loop between the return plenum and the supply trunk.
Identifying your model matters because the lamp wattage and housing depth vary. The label is on the motor housing, not the filter frame, and the serial prefix tells us whether you have the Texas-market spec with the upgraded gasket set (those handle higher static pressure, common in Schertz’s tighter-built homes from 2018 onward). OEM Abatement Technologies UV-C lamps run 254nm and carry a 9,000-hour rated life, but we also install quality aftermarket equivalents from American Ultraviolet that match the same ballast specs and housing dimensions at roughly 30% less parts cost. The aftermarket lamps we use carry the same 1-year replacement warranty, and we document the part number in your job record either way.
Signs Your Abatement Technologies Vent Sanitizing Is Failing
- The lamp indicator glows, but the borescope still shows biofilm on duct walls. A UV-C lamp can emit visible blue light while the 254nm germicidal output has dropped below effective levels. We meter actual UV output with a radiometer; anything below 40 microwatts per square centimeter at the duct surface isn’t doing the work.
- You smell a sharp ozone odor when the HVAC cycles on. Abatement Technologies UV-C lamps are non-ozone producing by design. If you’re getting ozone, the lamp seal has failed or someone installed a generic UVV lamp (odor oxidation) in a UV-C housing, which is a mismatch that can degrade the duct liner over time.
- The ballast hums loudly or cycles on and off. Magnetic ballasts in older Abatement Technologies units fail thermally in Texas attics where summer ambient temperatures exceed 140 degrees. We see this most often in Schertz homes with dark shingle roofs and limited soffit ventilation.
- Visible corrosion on the lamp housing or mounting bracket. The aluminum housings on pre-2020 units weren’t anodized for high-humidity return air streams. In Schertz, where spring humidity spikes before the AC has fully loaded, we’ve pulled housings with pitting severe enough to risk lamp breakage.
- The sanitizer was installed more than 14 months ago and has never been serviced. UV-C output degrades whether the lamp is lit or not; the quartz sleeve fouls with oil vapor from the blower motor. We treat this as a maintenance item, not a set-it-and-forget-it installation.
BeforeAfterReplacement Cost & What’s Included
For a typical Schertz home with one Abatement Technologies unit serving 8 to 12 supply runs, installed vent sanitizing runs $340 to $680. The lower end covers a straightforward UV-C lamp and housing swap on an existing CAP600-UV with accessible mounting. The upper end applies when we’re cutting in a new distribution manifold, running sanitizer lines to a second trunk, or dealing with a PREDATOR 750 on a commercial-grade flex-duct system in a larger home off Lookout Road.
Every quote breaks down parts and labor separately, per Haven Standard Clause 1. The lamp itself, OEM or aftermarket, is itemized. Labor includes removal of the old housing, borescope verification of the duct interior before and after, installation, output testing with a radiometer, and a written test report. The 365-Day Done Right Promise covers the installation and electrical connections; lamp failure within 12 months is replaced at no parts or labor charge. We don’t quote per vent or per square foot. One flat price per system, agreed in writing before we touch a panel.
DIY or Call Us?
There’s a safe middle ground here, and then there’s where DIY stops making sense. A homeowner can verify the model number, check whether the lamp indicator is lit, and confirm the breaker hasn’t tripped. What we don’t recommend is pulling a UV-C lamp housing yourself. The 277-volt ballast in commercial-grade Abatement Technologies units holds a lethal charge even when the breaker is off, and the quartz lamps shatter into fine glass that requires HEPA vacuuming if mishandled. We’ve responded to two calls in the Schertz area where a homeowner cracked a lamp trying to twist it out like a fluorescent tube; the mercury content in those older lamps requires specific disposal protocol.
Our crew carries the correct lamp extraction tools, the disposal containers, and the radiometer to prove the new lamp is actually emitting at spec. The before photo does the talking. I just bring the camera. If your Abatement Technologies unit is due for sanitizing service or the lamp hasn’t been checked in over a year, call us at (830) 402-5110. We’ll put a written price in your hand before we open the first panel, and you’ll get the photo record of every duct run when we leave.
FAQs
Expect 9,000 hours of rated germicidal output, which translates to roughly 12 to 14 months of continuous HVAC operation in this climate. In practice, Schertz’s longer cooling season means the lamp runs more hours annually than the manufacturer assumes, so we recommend annual replacement rather than waiting for the indicator to dim. Call (830) 402-5110 and we’ll meter your current lamp’s actual output; if it’s still above threshold, we’ll tell you and charge nothing for the check.
Ballasts and quartz sleeves can sometimes be replaced individually, but the labor to diagnose and source parts for an older Abatement Technologies unit often exceeds the cost of a new housing with a fresh lamp and warranty. We don’t recommend sinking money into a 2017-or-older magnetic ballast when the current electronic ballast retrofit drops energy draw by 40 percent and runs cooler in the attic. We’ll show you both options in writing before you decide.
A straightforward lamp and housing swap on an existing Abatement Technologies mount takes 45 to 90 minutes. A full distribution manifold install on a system that wasn’t originally set up for vent sanitizing runs 3 to 4 hours, including the borescope documentation and output testing. We schedule by the job, not the hour, so the price doesn’t change if we hit an unexpected duct configuration.
We carry UV-C lamps, housings, and ballasts compatible with the PREDATOR 750, CAP600, and HEPA-AIRE lines on every truck, including the 5-inch to 6-inch reducing boots for older units. Specialty items for discontinued series require a next-day pull from our San Antonio supplier. We’ll tell you before we schedule whether your specific unit needs a same-day or next-day part, and the written price reflects whichever it is.
