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 Littleton: What to Know First
We provide independent Nikro air quality and sanitizing in Littleton for homeowners who need mold treatment, bacteria sanitizing, odor removal, or UV light installation on Nikro equipment. Most jobs are completed in a single scheduled visit with a written price agreed before any work starts, and every duct run is photographed before and after. As an independent Nikro service provider, we are not affiliated with or authorized by Nikro - we service the equipment based on field experience, manufacturer documentation, and trade-standard practices. This page is for Littleton homeowners who own a Nikro air scrubber, UV system, or portable sanitizing unit and want to know what failing looks like, what fixing costs, and who will actually show them the problem before quoting a price. Call (720) 315-7291 for a free estimate.
How Nikro Products Fail - and How We Fix Them
- UV-C lamp degradation in the Nikro PS-series portable scrubbers. The PS-1 and PS-2 units use low-pressure mercury UV lamps rated for 9,000 hours, but in Littleton’s high-altitude, low-humidity environment, ozone precursor buildup on the quartz sleeve accelerates output decay. We measure actual UV-C intensity with a radiometer rather than trusting the hour counter, replace the sleeve if transmittance drops below 70 percent, and install only lamps that match the original 254-nanometer spec - not the cheaper 185-nanometer ozone generators some suppliers substitute.
- HEPA seal fatigue in Nikro HEPA-AIRE portable units. The silicone gasket between the HEPA filter and the blower housing hardens after repeated thermal cycling, especially in homes near the South Platte where basement humidity swings are wider. The symptom is a clean filter reading but elevated downstream particle counts. We pressure-test the seal with a smoke pencil, replace the gasket with closed-cell neoprene rated for the full temperature range, and document the before-and-after particle count with a handheld laser counter.
- Blower motor bearing wear in Nikro Abatement Technologies cross-branded units. The Nikro-branded Abatement PRED750 and PRED1200 negative air machines use sealed ball bearings that collect drywall dust during post-construction cleanup - common in Littleton’s active renovation market. The failure sounds like a low growl before it becomes a seized shaft. We pull the impeller, clean the bearing races with solvent, and if the runout exceeds 0.003 inch, we source the exact SKF equivalent rather than installing a generic motor that changes the unit’s CFM curve.
- Corrosion of the titanium dioxide catalyst grid in Nikro photocatalytic oxidizer (PCO) modules. The PCO-1 and PCO-2 add-on modules use a TiO2-coated aluminum honeycomb that degrades when exposed to the chlorine compounds common in Littleton’s municipally treated water - often introduced when homeowners run humidifiers on tap water. The symptom is a sour, metallic odor instead of the neutral post-treatment smell. We replace the grid with a coated stainless-steel substrate that resists chloride attack, or recommend bypassing the PCO if the homeowner prefers to stay with the original aluminum and use distilled water in their humidifier.
- Control board relay failure in Nikro APS-series whole-house air purifiers. The APS-2000 and APS-3000 use a single-board design with the UV ballast relay soldered directly to the main PCB; when the relay contacts pit from inrush current, the board throws a false “lamp fault” code. We trace the actual failure with a multimeter rather than replacing the lamp on spec, and if the board is damaged, we source the exact Omron relay for component-level repair rather than selling the homeowner a full replacement board they do not need.
Our Nikro Air Quality & Sanitizing Process

- 1
Inspection with documentation. We start every Nikro job by pulling the inspection camera and photographing the interior condition of the ductwork, the equipment mounting location, and any visible contamination on the Nikro unit itself. The camera doesn’t negotiate - it just shows what’s there.
- 2
Written scope and price. Before any panel comes off, we deliver a written scope that names the exact Nikro model, the diagnosed failure, the parts required, and the total price. Haven Standard Clause 1: no work starts without a signed written price.
- 3
Parts verification. For UV lamps, we verify the 254-nanometer spec against the original Nikro part number; for filters and seals, we use OEM or cross-referenced equivalent - never a “fits most” substitute that changes the pressure drop across the system.
- 4
Service execution with photo record. The technician performs the sanitizing, repair, or installation, photographing each critical step: the old part removed, the new part installed, the seal test, the UV intensity reading, or the particle count verification.
- 5
Functional testing and sign-off. We run the Nikro unit through its full cycle, measure output against manufacturer baseline, and have the homeowner review the photo record on a tablet before signing the completion document.
- 6
365-Day Done Right Promise delivered in writing. The warranty document is printed, signed, and left with the homeowner - not emailed later, not buried in a terms-of-service link.

- Whole-house UV light installation (new mount, electrical, lamp): $480-$720
What moves the price: accessibility of the Nikro unit (attic vs. basement), whether the ductwork requires pre-cleaning for the sanitizing to adhere properly, and whether we are matching an existing part or upgrading to a more durable equivalent. Every estimate is free, every price is written, and every job includes the documented photo record. Call (720) 315-7291 for an exact quote on your Nikro unit.
Why Littleton Homeowners Call CleanRun Air Duct Cleaning Littleton for Nikro Work

We have been cleaning and treating ductwork in Littleton since 2013, including plenty of jobs in the Columbine Knolls neighborhoods where the homes are older and the duct liners tend to tell a longer story than the listing price suggests. Tomas Reyes, our owner, pulls the inspection camera before quoting anything and walks homeowners through exactly what the footage shows - debris load, flex duct condition, register seal gaps - in plain terms, not sales language.
Our 365-Day Done Right Promise is backed in writing on every job, not just stated in marketing copy. Technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier air quality equipment, which matters when a Littleton home has mixed-brand HVAC components and the homeowner needs one technician who understands how the systems interact. The photo record, the written price, and the published license number - those are the reasons customers who research before calling tend to book with us.
FAQs
Does servicing my Nikro unit with CleanRun void the manufacturer warranty?
No. The Magnuson-Moss Warranty Act prohibits manufacturers from voiding a warranty solely because an independent service provider performed maintenance or repair, provided the work was done correctly and with appropriate parts. We document every step with photos and part numbers to protect your warranty rights. Call (720) 315-7291 if you have questions about your specific Nikro model.
How do I know if my Nikro UV lamp is actually working or just lit?
A glowing purple tube does not mean effective UV-C output; the 254-nanometer germicidal band degrades before the visible glow disappears. We measure actual intensity with a calibrated radiometer and show you the reading. If the output has dropped below the manufacturer’s minimum effective dose, we replace the lamp and sleeve together. Call (720) 315-7291 to schedule a UV verification.
Should I repair my older Nikro portable scrubber or replace it?
If the blower motor, HEPA housing, and control electronics are sound, replacement of wear items - lamps, filters, seals - is usually the better value. If the housing is cracked or the motor has been rebuilt once already, we will tell you that in writing and quote both options. Call (720) 315-7291 for a free second opinion on any written estimate you have received.
How long does a typical Nikro sanitizing job take?
Most residential Nikro air quality and sanitizing jobs in Littleton are completed in a single scheduled visit of two to four hours, depending on accessibility and whether duct pre-cleaning is required. We do not quote over the phone without seeing the unit; the written scope names the expected duration before you agree to the price. Call (720) 315-7291 to schedule an inspection.
Can you get parts for discontinued Nikro models?
We cross-reference Nikro part numbers against manufacturer specifications and maintain relationships with suppliers who stock discontinued lines. When an exact OEM part is unavailable, we source a verified equivalent and document the substitution in writing with the performance data. Call (720) 315-7291 with your model number and we will confirm availability before scheduling.
