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.
Nikro Air Quality & Sanitizing in Round Rock: What to Know First
We provide independent Nikro air quality and sanitizing services in Round Rock, with most scheduled jobs completed in a single visit and a written price delivered before any work begins. Typical whole-system sanitizing runs $340-$580 for a Nikro-equipped home, depending on system size and whether we’re treating for mold, bacteria, or post-construction allergens. This page is for Nikro owners in Round Rock who need documented results, not a sales pitch - call (737) 259-5752 for a free estimate with a written price guaranteed under Haven Standard Clause 1.
How Nikro Products Fail - and How We Fix Them
- Nikro PS1000 and PS2000 Series Portable Air Scrubbers: These units develop HEPA bypass when the gasket seal compresses after repeated filter changes, typically around the 18-month mark in Round Rock’s hard-water mineral environment. We replace the full gasket set rather than shimming, and we photograph the seal test with a smoke pencil so you can verify zero bypass before we leave.
- Nikro SL2000 and SL4000 Air Duct Cleaning Systems: The vacuum motor seal degrades faster here than in cooler climates because summer attic runs in Round Rock push operating temps past 140°F. We test static pressure at the collection drum and replace the motor seal with a high-temp silicone variant that holds spec through August - not the standard Buna-N that Nikro ships, which we document as a deviation on your job record.
- Nikro UV-C Lamp Housings (UVC Series): The quartz sleeve fouls with calcium scale from evaporative condensate in our limestone-heavy water zone, dropping UV output below the 40 µW/cm² kill threshold without triggering the lamp-fail indicator. We pull and inspect the sleeve with a borescope, descale with citric acid if the glass is intact, and replace if etched - we show you the sleeve photo before quoting either path.
- Nikro AX5000 and AX8000 HEPA Air Purifiers: The activated carbon pre-filter saturates prematurely in Round Rock homes near the Brushy Creek greenbelt where wildfire drift and cedar pollen loads run high. We meter VOC breakthrough with a ppb sensor rather than going by the calendar, and we stock the 2-inch and 4-inch carbon packs locally so you’re not waiting on a Dallas warehouse.
- Nikro PDV Series Portable Dehumidifiers (used in post-mold remediation): The defrost sensor drifts in Texas Gulf humidity, causing unnecessary compressor cycling that leaves rh above 55% - the mold regrowth threshold. We calibrate against a calibrated sling psychrometer, not the onboard display, and we log the reading on your photo record.
Our Nikro Air Quality & Sanitizing Process

- 1
Camera inspection of every main trunk line. We run a borescope through the plenum - the main distribution box where your ducts branch out - and photograph what we find before quoting. The camera goes in first. Then we talk.
- 2
Written price delivered on site. Haven Standard Clause 1: no exceptions. You get one flat price per system, no per-vent add-ons, before a single panel comes off.
- 3
Equipment selection from our verified roster. For Nikro jobs we deploy Nikro negative-pressure extractors where the ductwork calls for it, supplemented with Rotobrush contact agitation for fiberglass-lined runs, and Abatement Technologies HEPA filtration on the exhaust. We name what’s being used on your written scope.
- 4
OEM-spec or verified aftermarket parts. We use Nikro factory gaskets and filters where available; for the high-temp motor seals and carbon packs we source from trade suppliers with documented compatibility - never universal-fit substitutions that void your remaining warranty.
- 5
Post-work verification and photo record. We re-run the camera, meter UV output or static pressure as applicable, and deliver before-and-after photos of every duct run as a standard deliverable - not an upsell.
- 6
365-Day Done Right Promise in writing. If the work is not right, we make it right. The guarantee is printed, dated, and signed, not a web page policy.

Why Round Rock Homeowners Call CleanRun Duct Repair & Cleaning for Nikro Work

We’ve been in Round Rock since 2013, and we’ve learned what the limestone dust and cedar pollen do to ductwork here - Tomas Reyes grew up in Queens apartment buildings with ancient metal ducts, then spent two decades in the trade learning what textbooks skip. His crew knows Nikro equipment from hands-on repair, not a distributor slideshow. When a Stone Oak Ranch customer called last spring with a PS2000 pushing unfiltered air, we found the compressed gasket in ten minutes, fixed it same visit, and showed her the smoke-pencil seal test before packing up. We’re also equipped for Lennox, Trane, and Carrier systems when your home has mixed equipment. Every tech is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise applies to every job, and your photo record is delivered before we leave.
FAQs
No. As an independent Nikro service provider, we use warranty-safe practices and OEM-spec parts where required for coverage. We document parts sources on your job record so you have proof if a claim arises. For questions about your specific warranty status, call us at (737) 259-5752 with your model and serial number.
We photograph the inside of every duct run before and after, meter UV output or static pressure where applicable, and deliver the photo record as a standard part of the job. You don’t take our word for it; you see what the camera saw. If anything doesn’t match the written scope, the 365-Day Done Right Promise applies.
The $79 coupon model typically covers a shop-vac at the register and a bill that triples once the crew is in your home. We quote one flat price per system before starting, with no per-vent add-ons. The difference is documented work versus vacuum noise - we show you the photo record so you can judge for yourself.
Most UV lamp and sleeve issues are repairable for under $260. We replace the full housing only if the ballast has failed or the mounting flange is cracked - conditions we can show you on camera. If replacement makes more sense, we’ll say so in writing and explain why.
UV lamps lose output gradually and should be verified annually; HEPA and carbon filters in high-pollen zones like ours typically need inspection every 8-12 months. We don’t sell calendar-based maintenance contracts - we meter what’s there and tell you what the numbers show. Call (737) 259-5752 to schedule a free estimate with written pricing.
