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.

AfterNikro HVAC Cleaning in Denver: What to Know First
CleanRun Air Duct Cleaning Denver provides independent Nikro HVAC cleaning for Denver homeowners, with most jobs completed in a single scheduled visit and a written price delivered before any panel comes off. We service Nikro air handlers, evaporator coils, blowers, and condenser units across the metro area, from Capitol Hill’s original galvanized duct runs to newer builds in Stapleton and Highlands Ranch. Our crews carry Nikro-compatible tools including Rotobrush and Abatement Technologies negative-pressure extractors, and every job ends with a Documented Photo Record of what was found and what was removed. If you own a Nikro system and need coil cleaning, blower service, or full air handler maintenance, call (720) 799-2292. We will put a written price in your hand before work starts, every time.
How Nikro Products Fail - and How We Fix Them
Nikro builds solid commercial-grade equipment, but Denver’s altitude, dry winters, and summer dust storms create specific wear patterns we have documented across thousands of local jobs. Here is what we find when we open these units:
- Model 862 Series air handlers: The blower motor mounts on this series develop micro-vibration cracks after 6-8 years in Denver’s low-humidity environment. The motor does not fail electrically; it shifts position and throws the blower wheel out of balance, producing a low rumble that homeowners mistake for duct noise. We remove the assembly, photograph the mount fatigue, and replace with OEM or Guardian-grade mounts that match the original torque spec. The photo record shows the crack progression so you can see why replacement beat adjustment.
- Model 2000 negative air machines (used in larger Denver homes with integrated HVAC): The HEPA filter housing seal degrades faster here than at sea level because the rubber gasket contracts in dry winter air and re-expands unevenly. This bypasses dirty air past the filter and loads the evaporator coil with fine particulate. We replace the gasket with a silicone-based aftermarket seal rated for altitude cycling, then clean the coil with Nikro-compatible foaming agent and document the pressure drop before and after.
- Model 2200 series portable air scrubbers: The pre-filter pleats collapse inward when used continuously during Denver’s wildfire smoke season (June through September, increasingly). Reduced airflow forces the blower to work harder and draws more current through the contactor. We find this on units running in basement mechanical rooms with poor return air design. Our fix: clean or replace the pre-filter, inspect the contactor for heat discoloration, and note the return air deficiency in the written job record for your HVAC contractor.
- Model 1500 axial fan blowers: The blade pitch set screw loosens under thermal cycling in Denver’s 40-degree daily temperature swings during shoulder season. The blade shifts hub-deep and moves less air at the same RPM. Homeowners notice rooms that heated fine in October are cold in November. We torque the set screw to spec, balance the assembly, and photograph the blade position against the factory witness mark. If the hub is worn, we replace the blade and hub as a matched set - mixing old hub with new blade causes repeat failure in about 14 months, which we have documented on callbacks.
- Model 4000 series gas-powered negative air units: These see limited residential use in Denver but show up on large custom homes with crawl-space ductwork. The carburetor jets foul from altitude-rich fuel mixtures, and the resulting incomplete combustion produces carbon soot that migrates into the supply plenum. We do not service the engine - that belongs to a small-engine shop - but we clean the plenum and first duct runs with Nikro-compatible negative-pressure extraction, photograph the soot pattern to identify the source, and flag the fuel mixture issue in writing for your mechanical contractor.
Our Nikro HVAC Cleaning Process
- 1
Call and scope. We ask for the Nikro model number (on the data plate), the symptoms, and the last service date. We schedule a visit and state that a written price will follow inspection - no exceptions, per Haven Standard Clause 1.
- 2
On-site inspection with documentation. The technician photographs the unit condition, identifies the specific failure mode, and shows you the images before quoting. Here is what the camera found. Here is what it costs to fix it. You decide.
- 3
Parts decision. For discontinued Nikro series, we source quality aftermarket components from Guardsman or Abatement Technologies with equivalent pressure and temperature ratings. For current production, we quote OEM. We note the choice and warranty implication in writing.
- 4
Cleaning and repair. We perform the agreed scope - coil foaming, blower removal and cleaning, contactor inspection, seal replacement - using tools from our Nikro-compatible roster. Every duct run and component is photographed before and after.
- 5
Test and verify. We measure static pressure, temperature split, and airflow at the registers. The numbers go in your job record alongside the photos.
- 6
Written guarantee. The 365-Day Done Right Promise is printed, signed, and delivered with your photo record before we leave.

Why Denver Homeowners Call CleanRun Air Duct Cleaning Denver for Nikro Work
We are not a franchise operation. CleanRun is independently owned and operated under the Haven Standard, and Tomas Reyes has been photographing every register, plenum, and main trunk line since our first job in 2013. Our crews know Nikro equipment from hands-on work in Capitol Hill’s older furnace rooms and newer builds in RiNo, where integrated air scrubbers run harder than the spec sheet assumes. We also service Lennox, Trane, and Carrier systems, so when your Nikro unit is part of a mixed-manufacturer setup - common in Denver homes with aftermarket upgrades - we understand how the components interact. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is backed in writing, not mentioned in passing. And the Documented Photo Record is included on every visit, not sold as an upgrade.
FAQs
No, professional cleaning by an independent service provider does not void the Nikro warranty, provided no components are altered outside manufacturer specifications. We use Nikro-compatible cleaning agents and document our methods in your job record so warranty claims remain straightforward. If your unit is still under warranty, we note the service date and scope in writing for your files. Call (720) 799-2292 if you need a copy for your warranty administrator.
Yes, for most series we source quality aftermarket components from Guardsman or Abatement Technologies with equivalent pressure, temperature, and airflow ratings. For the Model 862 and 1500 series, we maintain a small inventory of common wear items because Denver’s climate predictably degrades them. We will tell you before ordering if a part is back-ordered or if an aftermarket equivalent is the better choice. The decision and its warranty implication are noted in your written price.
Replacement becomes the honest recommendation when the heat exchanger is cracked, the coil is leaking refrigerant, or repair parts are unavailable at reasonable cost. Everything else - dirty coils, worn blower mounts, degraded seals - we fix. We show you the photos, state the repair price, and if replacement is genuinely smarter, we say so and explain why. No pressure, just the camera evidence and the numbers. Call (720) 799-2292 for an inspection and written assessment.
Most residential jobs run 2.5 to 4 hours, depending on unit accessibility and what the inspection reveals. A straightforward evaporator coil cleaning on a basement air handler takes less time than a crawl-space blower removal with corroded mount hardware. We schedule the full day block so we are not rushing, and we leave only when the test numbers and photo record are complete. You will know the expected duration when we deliver the written price.
The $79 coupon model relies on arriving at your door and finding “additional problems” once the truck is in your driveway. We do not operate that way. Haven Standard Clause 1 requires a written price before work starts, every time, with no per-vent upsells. Our price includes the full cleaning scope, the Documented Photo Record, and the 365-Day Done Right Promise. The cheaper quote rarely includes all three, and often includes none. Bring us any written competitor estimate; we will put our number next to it for free.
