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 Chicago: What to Know First
We provide independent Nikro air quality and sanitizing services throughout Chicago, with most residential jobs scheduled within three to five business days and completed in a single visit. A typical Nikro mold treatment or bacteria sanitizing job in Chicago runs $340-$620 for a whole system, and we deliver that number in writing before any panel comes off. This page is for homeowners who already know they own Nikro equipment and need to understand what failing looks like, what fixing it actually costs, and how to tell whether the work got done. Call (708) 683-3974 for a free estimate with a written price delivered before we start.
How Nikro Products Fail - and How We Fix Them
- Nikro PS1000 and PS2000 portable air scrubbers: The HEPA filter seal gasket compresses unevenly after 18-24 months of seasonal cycling in Chicago’s humidity swings, creating a bypass path that lets unfiltered air recirculate. We replace the gasket with OEM-spec silicone and pressure-test the seal before the unit goes back online.
- Nikro EC5000 and EC7500 electrostatic precipitators: The ionizing wire tensioner corrodes faster than expected in lakefront homes where summer dew points stay above 70°F for weeks at a stretch. The wire sags, arcing drops collection efficiency by 40% or more, and the homeowner notices a metallic ozone smell. We clean the collector cell with Nikro-approved solution, replace the wire assembly, and verify micro-amp draw at the control board.
- Nikro UV200 and UV300 ultraviolet lamp systems: Lamp output degrades to sub-therapeutic levels after roughly 9,000 hours, but the indicator LED stays green because it only monitors ballast voltage, not actual UVC irradiance. We measure output with a calibrated UVC meter and replace lamps with matched-spectrum tubes, not generic germicidal bulbs that peak at the wrong nanometer range.
- Nikro APS500 and APS800 whole-home air purifiers: The activated carbon prefilter saturates prematurely in Chicago’s older two-flats and bungalows where decades of cooking residue and previous owners’ smoking have left adsorbed compounds in the ductwork. The carbon can’t take on new VOCs, and the homeowner gets “clean” air that still smells stale. We swap the carbon stage, document the old filter’s weight gain, and run a post-treatment odor panel at the supply registers.
- Nikro HRV150 and HRV200 heat recovery ventilators: The core develops mold growth on the exhaust-side channels when winter setpoints keep indoor humidity above 35% and the defrost cycle doesn’t fully dry the media. We remove the core, treat with EPA-registered sanitizer, and reset the defrost logic so the unit completes its dry cycle before the next ventilation period.
Our Nikro Air Quality & Sanitizing Process

- 1
Written price delivered first. We inspect the Nikro equipment, identify the model and serial, and give you a fixed price in writing before any work starts. Haven Standard Clause 1.
- 2
Photo documentation of baseline condition. Every register, every access panel, every filter slot - photographed before the vacuum hose or sanitizer goes in. Tomas Reyes has held this practice since 2013: show the photo first, talk second.
- 3
Diagnostic with manufacturer-specified tools. We use Nikro-compatible test equipment to measure what the homeowner is actually breathing, not what the indicator light claims. UVC meters, particle counters, pressure manifolds - the numbers go on the job record.
- 4
Parts decision: OEM or verified aftermarket. We stock Nikro OEM filters, lamps, and gaskets, and when an aftermarket equivalent meets the same spec at lower cost, we show the customer both options with the warranty implication of each, documented in writing.
- 5
Treatment and real-time verification. Negative-pressure extraction (suction that pulls contaminants out of the ductwork rather than pushing them deeper), followed by sanitizer application at manufacturer-specified dwell time, followed by post-treatment photography and air sampling at the supply registers.
- 6
Deliverables before we leave. Written scope of work, before-and-after photo record of every duct run, and the 365-Day Done Right Promise in writing. No exceptions.

These are whole-system prices, not per-vent teaser rates that balloon once the truck is in your driveway. Every figure above is agreed in writing before work starts. Call (708) 683-3974 for a free estimate - we’ll put our number next to any competitor’s written quote under our Free Second Opinion.
Why Chicago Homeowners Call CleanRun Duct Repair & Cleaning for Nikro Work

We’re an independent Nikro service provider, not a franchise or authorized dealer, which means we work for the homeowner’s interest, not a manufacturer’s quota. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they carry Nikro parts alongside Lennox, Trane, and Carrier inventory so a multi-brand household doesn’t get bounced between contractors. The 365-Day Done Right Promise is backed in writing on every job, not stated in marketing copy and forgotten afterward. Since 2013, we’ve served 52,000+ homes with a documented photo record on every visit - the inside of every duct run, before and after, delivered as a standard deliverable. In Chicago’s older housing stock, from Logan Square two-flats with Eisenhower-era galvanized ductwork to newer builds in Lincoln Park with flex runs, we’ve seen what Nikro equipment looks like when it’s actually working and when it’s only pretending to.
FAQs
No. As an independent Nikro service provider, we use OEM-specified parts and procedures that preserve warranty coverage; warranty voidance only occurs when non-specified parts or unqualified installation creates the failure. We document our parts sourcing and procedure on every job so that record exists if a warranty question arises. Call (708) 683-3974 if you need a second opinion on a dealer’s warranty claim.
You receive a documented photo record of every duct run before and after treatment, plus post-service air sampling results at the supply registers showing particle count and, where applicable, UVC irradiance levels. If the numbers don’t move, we don’t invoice. That’s Haven Standard Clause 1 - written price, verified result.
Replace when the housing has corrosion that compromises the HEPA seal path, when the blower motor draws more than 15% over nameplate amperage, or when repair costs exceed 60% of a comparable new unit installed. We document all three conditions with photos and written findings so you can decide from evidence, not pressure. Call (708) 683-3974 for a free evaluation with replacement and repair options priced separately.
A single-lamp retrofit in an accessible plenum takes 90-120 minutes; multi-lamp systems or jobs requiring new access panels take 3-4 hours. We schedule a four-hour window and typically finish early. The written price doesn’t change if we run over.
The $79-$129 coupon jobs typically fog a scented masking agent through the ducts without mechanical agitation or negative-pressure extraction, which leaves the biofilm intact and the homeowner with a temporary chemical smell and no lasting air quality improvement. We photograph what we remove so you can verify the difference. Call (708) 683-3974 for a free estimate with our written price before any work starts.
