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.
Guardsman Dryer Vent Cleaning in Round Rock: What to Know First
CleanRun provides independent Guardsman dryer vent cleaning in Round Rock with written prices delivered before any work starts and a documented photo record of every duct run. Most Guardsman dryer vent jobs we handle in Round Rock are completed in a single visit, with the full scope and exact price agreed in writing under Haven Standard Clause 1 before a tool comes off the truck. This page is for homeowners who own a Guardsman dryer vent system, have noticed longer dry times or a hot laundry room, and want to know what failure looks like, what fixing it costs, and who can do the work without voiding the original warranty. Call (737) 259-5752 for a free estimate.
How Guardsman Products Fail - and How We Fix Them
- Guardsman GVM series: flexible duct collapse at the elbow. The GVM’s semi-rigid transition duct, common in Round Rock homes built 2018-2022, flattens at the first 90-degree elbow where lint compacts against the ribbed wall. We’ve pulled 3-inch packed lint wedges from these elbows in Teravista homes where the dryer was pushed back too far after installation. We replace with a solid aluminum elbow and support strap, not another flexible run.
- Guardsman GVX exterior caps: louver seizure from cedar pollen. Round Rock’s cedar season coats the GVX’s lightweight plastic louvers in a film that hardens and jams them shut. The dryer still runs, but moist air backs into the laundry room. We clean the cap mechanism and, if the pivot pins are cracked, install a metal-bodied replacement that handles the same pollen load without binding.
- Guardsman GV-LongRun systems: sag in horizontal runs over 25 feet. Guardsman’s extended-vent kits, popular in Stone Oak Ranch’s larger floor plans, rely on ceiling supports every 4 feet. When builders skip a hanger, the duct sags, creating a lint trap that standard brushes miss. We run a camera first - the camera goes in first. Then we talk - to locate the low point, then use negative-pressure extraction (suction that pulls debris toward the vacuum, not just agitation) to clear it without dislodging the sag further.
- Guardsman GVM bird guard: mesh corrosion from humidity cycling. The factory mesh on GVM terminations rusts where Round Rock’s spring humidity meets winter dry air. Holes open, birds nest, and airflow drops by half before the homeowner notices longer dry times. We install a stainless mesh guard with the same ¼-inch aperture, which lasts past the original component’s failure point.
- Guardsman GVX sensor port: false blockage readings after cleaning. The GVX’s pressure-differential sensor port, meant to alert homeowners to blockage, can read permanently high if prior cleaning forced lint into the sensing tube. We blow out the port with regulated compressed air and verify the reading against a manometer before signing off.
Our Guardsman Dryer Vent Cleaning Process

- 1
Written price delivered first. We scope the job on arrival, run a camera through the full duct run, and deliver a written price under Haven Standard Clause 1 before work begins. No exceptions.
- 2
Guardsman-specific diagnostics. We identify the series - GVM, GVX, or GV-LongRun - and check for the known failure modes above, plus any manufacturer service bulletins we’ve logged since 2013.
- 3
Parts decision: OEM or verified aftermarket. For warranty-active systems, we use Guardsman OEM replacement caps and elbows. For out-of-warranty units, we offer quality aftermarket equivalents with documented specs, and we note the choice on the written invoice.
- 4
Cleaning with documented photo record. We photograph the interior of every duct run before and after cleaning, using Rotobrush and Nikro equipment. The customer receives these images as part of the standard job record.
- 5
Flow verification and final test. We measure exhaust velocity with an anemometer and compare against Guardsman’s published CFM range for the series. The result is recorded on the invoice.
- 6
365-Day Done Right Promise activated. The written guarantee is attached to the job record before we leave.

AfterWhat Guardsman Dryer Vent Cleaning Costs in Round Rock
| Service | Typical Range |
|---|---|
| Standard Guardsman vent cleaning (single-story, accessible cap) | $189 - $279 |
| Guardsman GV-LongRun cleaning with sag correction | $340 - $495 |

Price moves with three things: length of the duct run, accessibility (crawl space vs. second-story soffit), and whether we find a prior installation error that needs correction. We do not quote per-vent or offer teaser rates that change once the truck arrives. The price we write is the price you pay. Call (737) 259-5752 for a free estimate - we’ll put the exact number in writing before you decide.
Why Round Rock Homeowners Call CleanRun Air Duct Cleaning Round Rock for Guardsman Work

We’ve served Round Rock since 2013, including repeat jobs in Stone Oak Ranch and Teravista where Guardsman systems were original equipment. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they carry the full equipment roster - Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - so a Guardsman job doesn’t turn into a “we’ll come back” situation. We also service Lennox, Trane, and Carrier dryer vent systems, which matters in Round Rock’s resale market where mixed-brand HVAC packages are common. Every job ends with a documented photo record and the 365-Day Done Right Promise in writing. Tomas Reyes runs the crew, and he still checks the camera feed on every main trunk line before quoting.
FAQs
No, if the work is performed by a qualified technician using Guardsman-compatible parts and methods. As an independent Guardsman service provider, we document our process and parts to warranty standards, and we note any warranty-active status on your invoice so you have a record. Call (737) 259-5752 if you need help confirming your warranty period.
Replacement is necessary when the camera shows duct wall damage, corrosion holes, or repeated collapse at the same point after correction. Cleaning alone handles lint buildup and minor component wear. We show you the camera footage and explain which category your system falls into before any work starts. Call (737) 259-5752 for a free inspection.
Guardsman maintains parts availability for GVM and GVX series back to 2015; for older units, we source verified aftermarket equivalents with matching pressure and temperature ratings. We list the part origin on every invoice so you know what was installed. Call (737) 259-5752 to check availability for your specific model.
Every 12 to 18 months for standard households, and every 8 to 12 months if you dry pet bedding, work in construction trades, or live where cedar pollen loads are heavy - which includes most of Round Rock west of I-35.
