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 Round Rock: What to Know First
We provide independent Guardsman air quality and sanitizing service in Round Rock, typically scheduling within 3-5 business days and completing most jobs in a single visit. Every Guardsman system we touch gets a written price before we start, a camera inspection of every duct run, and our 365-Day Done Right Promise in writing on the invoice. Most Guardsman air quality work in Round Rock falls between $340 and $890 depending on whether we’re treating a single contamination event or installing whole-system UV protection. This page is for Guardsman owners in neighborhoods like Teravista, Stone Oak Ranch, and Forest Creek who’ve noticed persistent odors, elevated allergy symptoms, or visible microbial growth and want to know exactly what the fix costs before anyone opens a panel. Call us at (737) 259-5752 for a free estimate with no obligation.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GUV Series UV-C lamps lose output intensity after 9,000-12,000 hours. The lamp still glows, but the 254-nanometer germicidal output drops below effective levels. We measure actual UV output with a radiometer, not visual inspection, and replace with Guardsman-specified lamps or verified aftermarket equivalents that match the original dose curve. In Round Rock, where AC runs eight months straight, we see premature lamp degradation in homes near Brushy Creek where high humidity strains ballast components.
- Guardsman GAP Series electronic air cleaners develop ionizer wire corrosion from cedar pollen oxidation. The wire grid builds a conductive film that shorts sections to ground, reducing collection efficiency without triggering the fault light. We disassemble the cell, measure resistance across each wire segment, and either clean with manufacturer-approved solution or replace the ionizer assembly. Cedar season in Round Rock typically hits late December through February, and we document this pattern in Teravista homes with west-facing intakes.
- Guardsman GMS Series media cabinets harbor mold at the filter-to-frame seal. The pleated media traps moisture at the gasket interface, especially when the bypass damper sticks partially open. We remove the media pack, photograph the frame condition, treat with EPA-registered antimicrobial, and replace the gasket if compression set exceeds 1/8 inch. The camera goes in first. Then we talk.
- Guardsman GPC Series photocatalytic oxidizers accumulate catalyst fouling from construction dust. Newer Round Rock builds in Paloma Lake and Siena put fine drywall particulate into return air that coats the titanium dioxide mesh. We remove the catalyst core, assess porosity with backlight inspection, and either restore through ultrasonic cleaning or recommend replacement if airflow restriction exceeds 0.3 inches water column.
- Guardsman GUV-PRO ballast modules fail from heat cycling in attic-mounted systems. The epoxy potting cracks after repeated 140-degree summer days in unconditioned Round Rock attics. We test ballast output under load, and where replacement is needed we specify high-temperature-rated aftermarket ballasts with published MTBF data rather than generic substitutes that repeat the same failure.
Our Guardsman Air Quality & Sanitizing Process
- 1
System identification and history. We record the Guardsman model, serial, install date, and any prior service. We also note the home’s orientation, recent construction nearby, and whether the owner has noticed symptoms correlating with HVAC cycles.
- 2
Camera inspection of every duct run. Our Rotobrush inspection system travels the full length of each supply and return, photographing debris type, moisture staining, and microbial growth. The customer sees these images before any price is discussed.
- 3
Contamination testing and scope writing. We swab visible growth for lab identification when indicated, measure static pressure across the Guardsman component, and write a fixed-price scope listing exactly what we’ll do, what parts we’ll use, and what the customer receives.
- 4
Treatment or installation with documented procedure. For sanitizing, we apply Guardsman-compatible antimicrobial through negative-pressure extraction equipment from Nikro or Abatement Technologies. For UV or air purifier installs, we mount per manufacturer torque specs and seal all penetrations.
- 5
Post-work verification and photo record. We re-run the camera, capture after-condition images of every treated duct run, measure final static pressure, and deliver the complete photo record with the invoice.
- 6
Written guarantee activation. The 365-Day Done Right Promise goes into effect, backed by Haven Standard Clause 5: Documented Accountability.
BeforeAfterWhat Guardsman Air Quality & Sanitizing Costs in Round Rock
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Single-event microbial treatment (Guardsman GMS/GAP) | $340 - $520 | Number of duct runs, accessibility of plenum, severity of contamination |
| UV-C lamp replacement (Guardsman GUV series) | $280 - $440 | Lamp count, ballast condition, attic vs. closet access |
| Full-system sanitizing with photo documentation | $580 - $890 | System tonnage, duct material (flex vs. hardpipe), presence of mold requiring source removal |
| Guardsman-compatible air purifier install | $720 - $1,400 | Unit capacity, electrical requirements, integration with existing controls |
These are whole-system prices, not per-vent teaser rates. We do not quote by the register because that structure incentivizes cutting corners. Every price is written and agreed before work starts, per Haven Standard Clause 1. Call (737) 259-5752 for an exact quote - estimates are free.
Why Round Rock Homeowners Call CleanRun Air Duct Cleaning Round Rock for Guardsman Work
We’ve been in Round Rock since 2013, and we’ve learned that Guardsman owners here don’t want to hear about our “commitment to excellence.” They want to see the inside of their own ducts before they pay. Our 365-Day Done Right Promise is printed on every invoice, not just the website. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they arrive with name badges and the equipment list we publish - Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman units they can inspect. We also service Lennox, Trane, and Carrier systems, which matters when a Round Rock home has mixed-brand equipment and the real problem is at the interface. Tomas Reyes runs camera on the main trunk line personally when contamination patterns are unusual - he picked up that habit in Queens apartment buildings where the ductwork told stories the tenant never could.
FAQs
No. As an independent Guardsman service provider, we use warranty-safe practices and OEM or equivalent-specification parts. The Magnuson-Moss Warranty Act prohibits manufacturers from voiding warranties solely because an independent technician performed service, provided the work was done correctly and with appropriate components. We document parts sources on every invoice for this reason. Call (737) 259-5752 if you need warranty documentation for a claim.
We deliver before-and-after photos of every duct run as standard, and we measure static pressure before and after treatment. For microbial jobs, we can arrange third-party lab verification at additional cost, though most Round Rock customers find the photo record and pressure data sufficient. The 365-Day Done Right Promise covers re-treatment if visible contamination returns in the same location within twelve months.
The $79-$129 coupon model typically covers a brief vacuum at the registers, not full duct run treatment. We photograph the full length of every run because we’ve seen “cleaned” ducts in Round Rock homes that still contained debris at the first elbow. Our price covers complete negative-pressure extraction, antimicrobial application where indicated, and the documented photo record. We put the full scope in writing before starting - no surprises when the truck leaves.
Replace when repair exceeds 60% of new-unit cost, when the component is more than ten years old and uses obsolete parts, or when the underlying duct contamination that caused the failure hasn’t been addressed. We make this assessment with the camera evidence in front of you, not as a sales pitch. Our Free Second Opinion applies to replacement recommendations from other contractors - bring us their written estimate and we’ll put our number next to it.
UV lamps annually, media filters per pressure-drop indicator or every 6-12 months in high-pollen conditions, and full system evaluation every two to three years. Round Rock’s cedar pollen and extended cooling season accelerate loading compared to national averages. We don’t sell maintenance contracts - we call when it’s actually due based on your system’s runtime and what the camera shows.
