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 Katy: What to Know First
CleanRun Duct Repair & Cleaning provides independent Nikro service for air quality and sanitizing in Katy, TX, including mold treatment, bacteria sanitizing, odor removal, and UV light installation. Most Nikro jobs are scheduled within a few business days and completed in a single visit, with a written price delivered before any work starts under Haven Standard Clause 1. We’re not affiliated with or authorized by Nikro; we are an independent Nikro service provider with no ties to the manufacturer.
This page is for Katy homeowners who own a Nikro air scrubber, negative air machine, or HEPA filtration unit and need sanitizing, odor remediation, or air quality improvement that actually shows results. If your Nikro equipment is running but your home still smells musty, or if you’re trying to verify whether a sanitizing treatment was effective, we can help. Call (346) 666-7165 for a free estimate.
How Nikro Products Fail - and How We Fix Them
- UV-Aire series: lamp degradation without indicator failure. The UV-Aire’s ballast often continues drawing current after the 254nm lamp has dropped below effective output, so the blue glow looks right but germicidal output is gone. We meter actual UV-C output at the lamp surface before and after replacement, and we log the reading in your job record.
- PSI series negative air machines: HEPA seal fatigue in Katy humidity. The gasket interface between the filter bank and housing softens in our Gulf Coast summers, bypassing unfiltered air around the HEPA rather than through it. We pressure-test the seal with a smoke pencil and replace the gasket with a high-temp silicone specification that holds up in attics that hit 140°F in July.
- Air scrubber units: oxidizer cell fouling from local pollen loads. Katy’s oak and pine pollen seasons coat the titanium dioxide catalyst in Nikro’s photocatalytic units, cutting hydroxyl radical production by half. We remove the cell, document the fouling with photos, and either restore it with an ultrasonic bath or replace it with an OEM-spec cell if the substrate is etched.
- Portable HEPA units: motor bearing wear from continuous runtime. Nikro’s industrial HEPA units are built for intermittent remediation, but Katy homeowners often run them 24/7 after water damage. The motor draws higher amperage as bearings degrade, which we catch with a clamp meter before it burns out the control board. We replace the motor assembly with a matched OEM unit and note the pre-failure amp draw in your documentation.
- Sanitizing fogger attachments: residue buildup in the Venturi nozzle. The brass nozzle orifice in Nikro’s cold-fogging heads scales with quaternary ammonium compounds over time, producing uneven particle size and wet fallout on walls. We mic the orifice, replace it if it’s out of spec, and verify a dry fog at 20 microns with a particle counter before we leave.
Our Nikro Air Quality & Sanitizing Process

- 1
Call and scope. You describe the Nikro equipment model, what it’s doing or not doing, and what you smell or see. We schedule a visit and tell you the service call fee upfront.
- 2
Arrival and documentation. Our technician, identified by name before arrival, photographs the unit, serial plate, and surrounding conditions before touching anything. The before photo does the talking. Everything after that is just paperwork.
- 3
Diagnostics with metering. We test UV output, pressure differentials, amp draw, or particle counts as the specific unit requires. We show you the readings and explain what they mean.
- 4
Written scope and price. Before any work starts, you receive a written price for the exact repair or sanitizing treatment needed, with parts specified as OEM or quality aftermarket. No per-vent pricing, no add-ons after agreement.
- 5
Repair or treatment and verification. We complete the work, re-test with the same meters, and photograph the results. Sanitizing jobs include before-and-after ATP swab readings or particle counts.
- 6
Deliverables and guarantee. You get the photo record, the written scope, and the 365-Day Done Right Promise in writing before we leave.

Why Katy Homeowners Call CleanRun Duct Repair & Cleaning for Nikro Work

We’ve been running jobs in Katy since 2013, and Tomas Reyes, our owner, spent a stretch working older ranch-style homes near LaCenterra at Cinco Ranch where the ductwork tells you more about a house’s history than the seller’s disclosure ever will. That experience matters on Nikro jobs because the equipment doesn’t operate in isolation - it sits in attics and crawl spaces that behave differently here than in drier climates.
Every CleanRun technician works under Haven Standard Clause 3: Verified Crews - background-checked, uniformed, identified by name before arrival. We also service Lennox, Trane, and Carrier air quality equipment, so if your system mixes brands or you’re considering a change, we can compare options without a sales pitch. The 365-Day Done Right Promise applies to every job, backed in writing, not subject to manager approval.
FAQs
No - manufacturer warranties cover defects in materials and workmanship, not who performs routine service or repairs. We use OEM or equivalent-spec parts and document everything, so if a genuine defect emerges later, you have a clear service record to support your claim. For warranty questions specific to your unit, call us at (346) 666-7165 and we’ll review your serial number.
We measure before and after. For bacterial or mold treatments, we take ATP swab readings or air samples at the supply registers; for UV installations, we meter actual UV-C output at the lamp surface. You receive these numbers in your documented photo record. If the post-treatment readings don’t meet the target we set in writing, we retreat at no charge under the 365-Day Done Right Promise.
Replace when repair costs exceed 60% of a comparable new unit and the equipment is past seven years, or when the underlying ductwork problem that caused the failure hasn’t been fixed. We give you both numbers in writing - repair scope and replacement estimate - and we also service Lennox, Trane, and Carrier if you want to compare. No brand is pushed.
Most air quality and sanitizing jobs are scheduled within two to four business days. Emergency mold containment after water damage can sometimes be expedited. Call (346) 666-7165 for current availability - estimates are free.
The $79 coupon model typically covers a quick spray of deodorizer at the register, not source removal or verified treatment of the full duct run. We price by the scope of the actual job, not the square footage on your listing, and we document every run with before-and-after photos. The difference is verifiable - ask any competitor if they’ll show you the inside of every duct run, photographed, as part of the standard deliverable.
