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 Register & Grille Cleaning: The Round Rock Owner’s Guide
Guardsman register and grille cleaning in Round Rock typically runs $140-$280 per system for full removal, cleaning, and resealing, with most jobs scheduled within 48 hours. We stock Guardsman-compatible grilles and registers in common sizes for Round Rock homes built 2015-2025, and every job starts with a written price before a single screw turns. Homeowners usually notice the problem when airflow drops in one room, or when they pop off a grille and find the fins seized with compacted dust and pollen.
Which Guardsman Models This Applies To
Guardsman registers and grilles fall into three series you’ll find in Round Rock: the standard 5000 residential line, the 7000 heavy-duty line with reinforced nylon damper boxes, and the older 3000 metal-core series still common in Teravista and Stone Oak Ranch builds from 2015-2018. The 5000 and 7000 use a proprietary clip spacing - 5.75 inches on center for wall mounts, 6.125 inches for ceiling drops - that aftermarket grilles sometimes miss by an eighth-inch. That gap means whistling, or worse, a grille that seats but won’t seal.
We carry OEM Guardsman stock for the 5000 and 7000 series, plus quality aftermarket equivalents from Honeywell and Aprilaire that match the clip spacing exactly. For the 3000 metal-core line, Guardsman discontinued direct replacement in 2021, so we fabricate adapters or source compatible metal grilles with matching face dimensions. The label is usually inside the damper box, visible once you remove the grille. If it’s faded, measure the faceplate and the clip spacing - we’ll cross-reference before we quote.

Signs Your Guardsman Register & Grille Cleaning Is Failing

- Uneven airflow from room to room. The damper box inside a Guardsman grille collects dust at the pivot points, especially in Round Rock where cedar pollen peaks March through May. Once the damper sticks partially closed, the room never reaches set temperature no matter how hard the blower runs.
- Visible debris packed behind the grille face. We regularly find 2-3 inches of compacted dust at the first elbow behind master bedroom returns in newer Round Rock construction. The grille looks clean from the room side; the camera shows a different story.
- Whistling or rattling at the register. Guardsman grilles use a snap-fit retention clip that weakens over time. When the clip loosens, airflow vibrates the grille against the drywall - a sound that gets worse as the blower ramps to high stage.
- Discoloration or staining on the ceiling around ceiling-mounted grilles. This usually means the gasket between grille and duct boot has failed, allowing conditioned air to leak into the attic space. In Round Rock’s cooling-heavy climate, that leak costs more than the repair.
- Grille won’t stay seated or falls out when touched. The plastic retention tabs on 5000-series grilles fatigue after 6-10 years of heat cycling. We see this most in west-facing rooms where attic temperatures spike the ductwork hardest.

What drives the range: accessibility (ceiling drops take longer than wall mounts), whether the duct boot needs resealing, and whether we’re cleaning existing hardware or swapping to new. Every quote is written and agreed before work starts, per Haven Standard Clause 1. The 365-Day Done Right Promise covers the labor and any hardware we install. We also photograph every grille location before and after - part of the Documented Photo Record included on every visit since 2013.
DIY or Call Us?

What you can safely check yourself: pop the grille off and look inside. If you see loose dust, a vacuum with a soft brush attachment handles surface cleaning. Check the damper moves freely by hand - it should swing full open and full closed without binding.
Where DIY goes wrong: forcing a seized damper bends the linkage, and compressed debris at the duct elbow is usually beyond reach of household tools. We’ve replaced grilles that owners cracked trying to pry them free with a screwdriver, or that they reinstalled without gasket sealant, turning a $85 job into a $200 fix plus attic air loss. The camera goes in first. Then we talk.
If you’re seeing staining, hearing whistling, or the grille won’t seat properly, call (737) 259-5752. We’ll run a scope, show you what’s actually back there, and put a written price in your hand before any work starts.
FAQs
Typically 10-15 years for the 5000 and 7000 series, but cedar pollen and construction dust in newer Round Rock neighborhoods can shorten that to 7-10 years. The plastic components fatigue faster in attics that hit 140°F in August. Call (737) 259-5752 for an exact assessment of your hardware.
Sometimes. A seized damper can often be freed and relubricated; a cracked faceplate cannot. We make that call after inspection, and we’ll show you the photo before recommending either path. If repair makes sense, we’ll quote it in writing - Haven Standard Clause 1.
20-45 minutes per unit for straightforward replacement, longer if the duct boot needs resealing or the damper box is seized. A full home with 12-16 registers typically takes 3-4 hours. We schedule by the job, not by the hour, so the price stays fixed.
Yes. We carry common 5000 and 7000 series grilles, registers, and gaskets in standard sizes for Round Rock homes. For the discontinued 3000 metal-core line or unusual dimensions, we source within 24 hours and return to install - no second trip charge.
