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 Leander: What to Know First
We provide independent Guardsman air quality and sanitizing service throughout Leander, with most scheduled jobs completed in a single visit and a written price delivered before any work starts. A typical Guardsman UV light install or full-system sanitizing runs $340-$780 depending on system size and whether the plenum (the main distribution box above your furnace) needs opening. We’re not affiliated with Guardsman - we’re an independent service provider - and we don’t quote per-vent teaser rates. Call (737) 252-1285 for a written estimate.
This page is for Leander homeowners who already own Guardsman air quality equipment or are considering it, and want to know what honest service looks like without the coupon-runaround.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GUV Series UV lights lose output after 12-18 months. The 254nm lamp degrades faster in Leander’s hard water areas because mineral scale on the quartz sleeve blocks UV-C transmission. We pull the sleeve, photograph the scale buildup, and replace with a quality aftermarket lamp or OEM - your choice, priced in writing before we open the access panel.
- Guardsman GAP media air cleaners develop bypass gaps. The snap-fit frame on earlier GAP-1625 units can warp from attic heat cycling in Texas summers, letting unfiltered air slip around the MERV-13 media. We measure the gap with a smoke pencil, document it, and install a rigid aluminum frame upgrade that seals properly.
- Guardsman GAP carbon odor filters saturate prematurely in Leander’s cedar pollen season. The activated carbon loads with pollen oils before it ever touches VOCs, killing odor removal. We check the pressure drop across the media; if it’s high with no odor improvement, the carbon is pollen-blind and needs replacement with a separate particulate pre-filter stage.
- Guardsman GUV ballasts fail from voltage fluctuation. Leander’s rapid growth has meant grid instability in newer subdivisions like Crystal Falls, and the GUV’s electronic ballast is sensitive to sags below 108V. We test line voltage at the unit, photograph the reading, and install a surge-protected ballast if the grid’s dirty.
- Guardsman sanitizer dispensers clog at the nozzle. The GSD-200 series uses a venturi injection point that crystallizes with Leander’s calcium-heavy water, blocking the quaternary ammonium flow. We disassemble and bore-scope the line, then flush with deionized water and replace the orifice - documented before and after.
Our Guardsman Air Quality & Sanitizing Process
- 1
Call and schedule. A live person answers, confirms your Guardsman model if you know it, and books a window. No “call for a quote” - Haven Standard Clause 1 means we show up ready to write a price.
- 2
Inspection with camera. Tomas Reyes pulls the inspection camera before quoting anything. If it doesn’t show up on screen, we don’t charge for it. We photograph the plenum interior, UV sleeve condition, and media fit.
- 3
Written price delivered. Scope, parts options (OEM Guardsman or quality aftermarket), labor, and total - signed before work starts.
- 4
Service execution. We use Rotobrush and Abatement Technologies equipment for duct access, and install Guardsman, Honeywell, or Aprilaire replacement components per your approval.
- 5
Testing and documentation. UV output verified with a radiometer, pressure drop checked, and every duct run photographed before and after. The photo record is yours as a standard deliverable.
- 6
365-Day Done Right Promise in writing. If it’s not right, we make it right - backed on paper, not subject to manager approval.

What moves the price: system accessibility (crawl space vs. closet), whether the plenum needs cutting and patching, and if we find pre-existing mold that requires source remediation before sanitizing. We also service Lennox, Trane, and Carrier systems with the same upfront pricing.

Why Leander Homeowners Call CleanRun Air Duct Cleaning Leander for Guardsman Work
We’ve been running crews in Leander since 2013, including regular jobs in Crystal Falls where new-construction debris and cedar pollen make air quality equipment work harder than the manual suggests. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, identified by name before arrival. Every job carries the 365-Day Done Right Promise in writing, and every duct run is photographed before and after - a practice we’ve held since our first job. We’re independently owned and operated, not a franchise, and we publish our license number where you can find it. Show the photo first. Then talk about what comes next.
FAQs
No. Routine maintenance and filter replacement by an independent provider does not void your Guardsman warranty, though we document our work in case of any future claim dispute. We note whether we used OEM or aftermarket parts in your job record. Call (737) 252-1285 if you need a copy for your files.
Replace on schedule. UV-C output drops below effective germicidal levels long before the lamp goes dark - typically 12-14 months in Leander’s conditions. We measure actual output with a radiometer during service; if it’s below 40 microwatts per square centimeter, the lamp is decorative, not functional. Call (737) 252-1285 for a lamp output check.
The $79 coupon model typically covers a shop-vac at the register and a photo of a clean vent cover - not the plenum, not the duct runs, not the equipment. We photograph inside every run and price the whole system in writing before starting. If you have a competitor’s written estimate, we’ll put our number next to it free under our Free Second Opinion policy.
You receive a Documented Photo Record of every duct run, before and after, plus the written scope you signed. For UV installs, we include the radiometer reading. If the photo doesn’t show the difference, we didn’t do the job right - and the 365-Day Done Right Promise covers making it right.
UV lamps annually, media filters every 6-12 months depending on pollen load, and full system inspection every two years. Leander’s cedar season and construction dust mean filters load faster than in less active growth areas. We don’t sell maintenance contracts - we call when it’s due, and you decide. Call (737) 252-1285 to check your schedule.
