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 Schertz: What to Know First
We provide independent Guardsman air quality and sanitizing in Schertz, TX, with most jobs completed in a single scheduled visit and a written price delivered before any work begins. Guardsman air purifiers, UV light systems, and whole-home sanitizing equipment - common in Schertz builds from 2017 onward, particularly the GAP series and GUV-C ultraviolet lines - require service that accounts for their proprietary control boards and filter dimensions. We’re not a coupon operation; we’re a documented-record shop. If you own a Guardsman system and need mold treatment, bacteria sanitizing, odor removal, or UV light installation in Schertz, call (830) 402-5110. We’ll inspect, photograph what we find, and put a flat price in writing before touching a panel.
How Guardsman Products Fail - and How We Fix Them
- GAP-2000 and GAP-3000 electronic air purifiers: The ionizing wires in these units collect a calcium-rich scale from Schertz’s moderately hard water supply, which insulates the wire and drops ion output by half without tripping any fault code. We remove the cell assembly, media-blast the wire set with a Nikro contact cleaner, and verify output with a handheld ion counter before reassembly. The before photo does the talking. I just bring the camera.
- GUV-C series UV-C lamp housings: The quartz sleeve that separates the lamp from the airstream cracks at the mounting gland after 18-24 months in Texas attics, where summer temperatures in Schertz routinely exceed 140°F. We source the correct 15mm replacement sleeve rather than substituting a generic 16mm tube, which leaks UV-C at the seal and degrades the surrounding plenum.
- Guardsman whole-home sanitizing injectors (GWS-100): The Venturi nozzle clogs with iron bacteria common in Schertz’s groundwater-influenced supply, causing uneven distribution and a sulfur smell at the far registers. We pull the injector, borescope the downstream duct runs, and replace the nozzle with an OEM-spec part or a verified Abatement Technologies equivalent.
- GAP series pressure-drop sensors: These sensors misread when the reference tube accumulates construction dust - a constant issue in newer Schertz subdivisions like those off Roy Richard Drive where drywall fines linger in ductwork for years. We clean the reference circuit and recalibrate against a digital manometer, not the on-board display.
- Guardsman odor-removal carbon banks: The activated carbon reaches saturation faster than the rated 36 months in Schertz homes with crawl-space return paths, where soil-gas intrusion loads the media with VOCs the manufacturer didn’t design for. We document the breakthrough with a photo of the spent bank, replace with fresh Guardsman-spec carbon, and seal the crawl return if the customer approves the additional scope.
Our Guardsman Air Quality & Sanitizing Process
- 1
Scheduled arrival, verified crew. Our technician arrives in a CleanRun uniform, background-checked under Haven Standard Clause 3: Verified Crews, and calls 30 minutes out with a name and ETA.
- 2
Visual and borescope inspection. We photograph the interior of every accessible duct run, the plenum, and the Guardsman unit itself before touching anything. You see what we see.
- 3
Written scope and flat price. Haven Standard Clause 1: every job gets a written price before work starts. No per-vent math, no add-ons after the truck is parked. One flat price per system.
- 4
Service with documented parts. We use Guardsman OEM or trade-verified aftermarket components - Honeywell, Aprilaire, or Abatement Technologies equivalents where appropriate - and photograph each installed part’s label.
- 5
Post-service test and photo record. We run the system, verify airflow and sanitizing output, and deliver a second set of photos showing the completed work. The photo record is included as a standard deliverable on every visit.
- 6
Written guarantee. The 365-Day Done Right Promise goes on the invoice. If it’s not right, we make it right. That’s in writing, not a policy subject to manager approval.
BeforeAfterWhat Guardsman Air Quality & Sanitizing Costs in Schertz
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Guardsman UV-C lamp and sleeve replacement | $340-$520 | Single vs. dual-lamp housing; attic accessibility |
| GAP series ionizing cell cleaning and test | $180-$280 | Scale severity; cell condition (some require replacement) |
| Whole-home sanitizing injection service | $420-$680 | System tonnage; number of supply branches treated |

These are whole-system prices, not per-vent teasers. The $79 coupon shops in San Antonio metro typically arrive with a shop-vac and leave with a bill three times their advertised rate. We don’t operate that way. Call (830) 402-5110 for a free estimate - we’ll put an exact number in writing before any work starts.
Why Schertz Homeowners Call CleanRun Air Duct Cleaning Schertz for Guardsman Work
We’ve been working Schertz long enough to know which builders spec’d Guardsman equipment in their 2017-2022 builds and which subcontractor installed it. That matters when the GUV-C lamp housing is mounted backward against the coil, a configuration we see regularly in the newer subdivisions off FM 3009. Our crew also carries Lennox, Trane, and Carrier parts on the truck, so if your system is hybrid-branded, we don’t leave to order components. Every job ends with a Documented Photo Record of every duct run, delivered to you as part of the standard job record. The 365-Day Done Right Promise is backed in writing on every invoice. Tomas Reyes and his crew have pulled flex duct and cleaned plenums in this market for several years now - from Roy Richard Drive builds to older homes where the ductwork hasn’t been touched since installation.
FAQs
No. As an independent Guardsman service provider, we use OEM-spec or equivalent parts and document every step, which satisfies warranty requirements for routine maintenance and repair. We are not affiliated with or authorized by Guardsman, and we never imply manufacturer endorsement. Keep your invoice and photo record; they’re your proof of proper service if a warranty claim ever arises. Call (830) 402-5110 if you need documentation for a warranty submission.
We show you. Our standard deliverable includes before-and-after photos of the duct interior, plus a written test record of system pressure and airflow post-service. For UV-C jobs, we verify lamp output in microwatts per square centimeter at the specified distance. If the numbers don’t move, we don’t invoice for work that didn’t happen. The photo record is included on every visit.
The $79-$99 offers are typically per-vent teaser rates that exclude the main trunk, the plenum, and any actual sanitizing. By the time the crew is in your driveway, the price inflates to $400-$800 for work a shop-vac could do. We quote one flat price per system, agreed in writing before work starts, with no per-vent arithmetic. Haven Standard Clause 1.
Repair if the housing and controls are sound and the unit is under ten years old; replace if the control board is obsolete or the plenum housing is cracked. We carry Lennox, Trane, and Carrier equipment lines if replacement makes sense, and we’ll put both options in writing with a flat price for each. No default to the more expensive path.
UV-C lamps need replacement every 12-14 months regardless of brand - the mercury arc degrades on schedule, not on use. GAP series ionizing cells need deep cleaning every 18-24 months in Schertz’s hard-water environment. Whole-home sanitizing injectors need nozzle inspection annually. We don’t sell maintenance plans; we photograph what we find and let you decide.
