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 HVAC Cleaning in San Antonio: What to Know First
CleanRun provides independent Nikro HVAC cleaning in San Antonio for homeowners who want the work photographed, priced in writing, and guaranteed for a full year. Most Nikro evaporator coil and blower cleanings are completed in a single scheduled visit, with your written price delivered before we touch a single panel. We’re not a coupon shop, and we don’t quote per-vent or teaser rates that balloon once the van is in your driveway. If you own a Nikro air handler or coil system and need it cleaned properly, call us at (726) 600-7155. The estimate is free, and the price we write down is the price you pay.
How Nikro Products Fail - and How We Fix Them
- Nikro 860 Series air scrubber blower motors seize from dust packing the squirrel cage. In San Antonio, the combination of caliche dust and high summer humidity cakes onto the blower fins until the motor draws excessive amperage and trips thermal overload. We remove the entire blower assembly, clean each fin with compressed air and contact-safe solvent, and photograph the amp draw before and after reassembly.
- Nikro SL4000 series evaporator coils develop mold at the downstream edge where condensate drains slowly. The SL4000’s A-frame coil geometry creates a low spot that standard drain pan slope doesn’t fully clear in older Alamo Heights installations with settled foundations. We pull the coil, clean with foaming cleaner rated for aluminum microchannel fins, treat with a non-coating biocide, and verify drain flow with a measured water pour.
- Nikro 220V portable HEPA units suffer capacitor swelling in unconditioned Texas garages. The capacitor sits adjacent to the motor housing with minimal heat shielding; San Antonio attic temperatures above 130°F in July cook the electrolyte. We test capacitance with a multimeter, replace with spec-matched aftermarket or OEM per your preference, and log the reading in your job record.
- Nikro duct-mounted UV units lose output when quartz sleeves accumulate hard water scale from condensate mist. The sleeve transparency drops, the UV-C dosage falls below the 40 µW/cm² threshold for effective coil irradiation, and microbial growth resumes. We remove and descale sleeves with diluted phosphoric acid solution, not abrasive pads that scratch, then verify output with a UV meter we bring to every job.
- Nikro negative air machines develop filter bypass when HEPA frames warp from repeated San Antonio humidity cycles. The MDF or particleboard frames on older units absorb moisture, swell, and no longer seal against the gasket. We measure frame squareness, replace with marine-grade plywood or factory frames depending on parts availability, and perform a DOP challenge test before returning the unit to service.
Our Nikro HVAC Cleaning Process

- 1
Scope and photograph first. We feed a camera scope through the plenum, the open ductwork, and across the coil face before writing anything down. Tomas Reyes put this in place back in 2013: the camera goes in first. Then we talk.
- 2
Deliver written price on site. Haven Standard Clause 1: your price is written, itemized, and agreed before work starts. No exceptions.
- 3
Diagnose parts needs with OEM and aftermarket options. For Nikro systems, we stock common blower belts, capacitors, and UV sleeves; for discontinued lines, we source quality aftermarket equivalents and show you the manufacturer spec sheet before installing.
- 4
Clean and document every stage. We use Nikro-compatible foaming agents on coils, HEPA-contained brushing on blowers, and negative-pressure extraction on duct runs. Every step is photographed for your record.
- 5
Test and measure. Static pressure, amp draw, temperature split, and UV output where applicable. The numbers go in your job folder with the photos.
- 6
Deliver your Documented Photo Record and written 365-Day Done Right Promise. Before we leave, you have every photo, every measurement, and our guarantee in writing.

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

We’ve cleaned Nikro equipment in San Antonio since 2013, and we’ve learned what the local climate does to these systems. Caliche dust, 100-degree attics, and limestone-heavy water create failure patterns you don’t see in Nikro’s Ohio documentation. Our crews are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we also service Lennox, Trane, and Carrier systems, so we’re not guessing when your Nikro interfaces with another brand’s thermostat or zoning panel. Every job ends with a Documented Photo Record and our 365-Day Done Right Promise in writing. If you bring us a competitor’s written estimate, we’ll deliver a free second opinion with our number beside it.
FAQs
No, professional cleaning by an independent service provider does not void your Nikro warranty, provided we use manufacturer-compatible methods and do not modify electrical or refrigerant circuits. We document our process and products used so you have a record if a warranty question ever arises. Call (726) 600-7155 if you’d like us to review your warranty terms before scheduling.
The camera shows the difference. A rinse-ready coil has light surface dust; a coil needing full service has matting between fins, oily residue, or visible microbial growth. We show you the scope image before quoting, so you decide based on what you see, not what we say. Free estimates are available at (726) 600-7155.
We source both. For current Nikro lines, OEM parts are typically available with a 3-5 day lead time. For discontinued series like early SL4000 units, we use quality aftermarket equivalents from Guardsman and Abatement Technologies, and we show you the spec comparison in writing before installation. Haven Standard Clause 1 applies: no work starts until you’ve approved the parts choice and price.
Clean it first, then decide. A properly cleaned coil and blower can restore 10-15% of lost efficiency, and our photo record gives you objective data on component condition. If the heat exchanger shows cracks or the blower motor draws locked-rotor amps, we’ll document that too and discuss replacement without pressure. The estimate is free: (726) 600-7155.
Most residential Nikro cleanings take 2.5 to 4 hours from arrival to final test, depending on system configuration and contamination level. We schedule a dedicated window, not a vague “morning or afternoon” block, and our technician calls 30 minutes before arrival. Call (726) 600-7155 to book a slot that works for your calendar.
