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 San Antonio: What to Know First
CleanRun Duct Repair & Cleaning provides independent Nikro air quality and sanitizing services in San Antonio, with most residential jobs completed in a single scheduled visit and a written price delivered before any work begins. We are not affiliated with or authorized by Nikro; we service their equipment as an independent Nikro service provider using trade-standard tools and documented procedures. Typical whole-system sanitizing and air quality treatment for Nikro-equipped homes in San Antonio runs $340-$780 depending on system size and contamination level. If you own a Nikro air scrubber, UV system, or negative air machine and need mold treatment, bacteria sanitizing, odor removal, or allergen reduction, call (726) 600-7155 for a free written estimate.
How Nikro Products Fail - and How We Fix Them
- UV-2000 series lamp degradation in hard water zones. The UV-2000 and UV-2000+ units installed in San Antonio homes since 2018 show premature lamp dimming when calcium and magnesium in local municipal water supply coat the quartz sleeve. We remove the sleeve, measure UV-C output with a radiometer, and replace with OEM-spec 254nm lamps or documented-equivalent aftermarket units. The fix includes a sleeve cleaning protocol we developed after seeing this pattern repeat in Alamo Ranch and Helotes installations.
- APS-2000 plenum seal fatigue from thermal cycling. Nikro’s APS-2000 whole-home air purifier uses a gasketed plenum interface that stiffens after three to four San Antonio summers of 100°F+ attic runs. The seal cracks, bypassing untreated air around the filter media. We replace with silicone-impregnated gaskets rated for sustained 180°F, pressure-test the plenum to 0.5 inches water column, and photograph the seal interface before and after.
- Negative air machine HEPA loading in pollen-heavy spring seasons. Nikro’s SL-2000 and SL-4000 negative air machines, common in San Antonio remediation jobs, load HEPA filters faster than manufacturer intervals suggest due to mountain cedar and oak pollen peaks in March and April. We log pre-filter differential pressure, replace HEPA when ΔP exceeds 2.5 inches (not by calendar date), and document the reading on the job record.
- PCO-1000 catalyst fouling from cooking VOCs. The photocatalytic oxidation grid in Nikro’s PCO-1000 series binds with lipid aerosols from gas cooktops - a frequent finding in San Antonio’s older Terrell Hills and Monte Vista kitchens. We remove the catalyst assembly, ultrasonic-clean the titanium dioxide substrate, and verify VOC reduction with a calibrated PID meter before reinstalling.
- Flex-duct adapter loosening on Nikro portable units. The cam-lock adapters shipped with Nikro’s portable HEPA units vibrate loose during extended runtime on San Antonio’s slab-on-grade homes, where equipment sits on concrete rather than suspended flooring. We install secondary hose clamps at flex-duct transitions and vibration-isolate the unit base with closed-cell pads - a field modification we’ve standardized after logging it on dozens of Stone Oak jobs.
Our Nikro Air Quality & Sanitizing Process

- 1
Scope and photo baseline. We insert a camera scope into the plenum and first duct run before writing any numbers. The camera goes in first. Then we talk. You see what we see on a tablet before the quote is prepared.
- 2
Written price under Haven Standard Clause 1. We deliver one flat price per system, agreed in writing, before any panel comes off or any sanitizing agent is mixed.
- 3
OEM or verified-equivalent parts selection. For Nikro systems, we source OEM lamps, gaskets, and HEPA filters when available; when lead times extend beyond 10 business days, we document the aftermarket equivalent’s specifications and obtain your approval in writing.
- 4
Service execution with real-time documentation. Technicians photograph each stage - pre-condition, component removal, post-service condition - with timestamps. The photo record becomes part of your job file.
- 5
Post-service verification and test. We run the system through a complete cycle, measure airflow at registers with a balometer, and verify sanitizing agent dwell time or UV output per manufacturer protocol.
- 6
365-Day Done Right Promise delivery. The written guarantee is included with your photo record and invoice before the crew leaves. Haven Standard Clause 6: Accountable Work.

Why San Antonio Homeowners Call CleanRun Duct Cleaning San Antonio for Nikro Work

We’ve logged thousands of hours in San Antonio homes since 2013, including tract builds near Stone Oak where flex duct collapses and dust accumulation are textbook examples of what we document on every job. Tomas Reyes, our owner, trained in HVAC systems technology at Queensborough Community College and developed our photo-first protocol after years of hands-on ductwork across the Northeast and Texas. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier air quality equipment, so multi-brand homes get consistent documentation standards across every unit. The 365-Day Done Right Promise is backed in writing, not subject to manager approval. And every job file includes the before-and-after photo record we’ve delivered since our first San Antonio call in 2013.
FAQs
Nikro’s warranty covers manufacturing defects, not field service or consumable replacement. Our work is backed by CleanRun’s 365-Day Done Right Promise, independent of any manufacturer coverage. Call (726) 600-7155 for a free written estimate.
Rated life is 9,000-12,000 hours, but San Antonio’s hard water and high attic temperatures reduce effective UV-C output sooner than the calendar suggests. We measure output with a radiometer and replace when intensity drops below 40 µW/cm², not by the printed date. Call (726) 600-7155 to schedule a lamp test.
We source OEM lamps, gaskets, and HEPA filters when available with reasonable lead time. When OEM is back-ordered, we use documented-equivalent aftermarket parts with published specifications, and we show you the spec sheet before installation. Call (726) 600-7155 to check current availability for your model.
Replacement makes sense when repair exceeds 60% of replacement cost or when the unit is more than 10 years old with multiple component failures. We provide both numbers in writing under Haven Standard Clause 1 so you can compare. Call (726) 600-7155 for an honest assessment.
Every job concludes with a Documented Photo Record of every duct run and component serviced, timestamped and delivered as part of your standard job file. We also measure and log post-service airflow and, where applicable, sanitizing agent dwell time or UV output. You keep the record; we keep the backup. Call (726) 600-7155 to schedule a documented service.
