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 Duct Cleaning in Denver: What to Know First
CleanRun Duct Repair & Cleaning provides independent Nikro air duct cleaning in Denver for residential and commercial systems, with most jobs completed in a single scheduled visit and a written price delivered before any work begins. A typical single-family home in Denver runs $380-$620 for full supply and return duct cleaning using Nikro-compatible negative-pressure equipment, with commercial systems starting around $1,200 depending on plenum access and duct run count. This page is for Nikro equipment owners in Denver who want to know what the service actually involves, what it costs, and how to verify the work was done. Call (720) 799-2292 for a written estimate.
How Nikro Products Fail - and How We Fix Them
- Nikro SL4000 Series portable extractors: The vacuum motor seals harden in Denver’s low-humidity climate, dropping suction pressure below the 2,000 CFM spec needed for proper negative-pressure extraction (the method that pulls debris out without releasing it into living space). We test suction at the plenum with a manometer first. If the motor’s below spec, we swap in a replacement from our Nikro-compatible inventory or switch to our Abatement Technologies PREDATOR 800 as backup - documented in your photo record either way.
- Nikro HP20 and HP30 gas-powered truck mounts: The Kohler engine air filters clog faster along Denver’s Front Range due to fine caliche dust from new construction zones in Stapleton and Central Park. We pull and photograph the filter condition before starting, replace it from stock if it’s choked, and log the engine hour reading. A choked filter on an HP20 produces black carbon streaking inside duct runs that shop-vac cleaning just relocates.
- Nikro SL2000 electric portables: The poly tank seams stress-crack after repeated freeze-thaw cycles in unheated Denver garages. We inspect the tank integrity during setup; a cracked tank loses seal and sprays fine particulate through the HEPA exhaust. Our fix is a tank swap with a Rotobrush HEPA-compatible unit for that job, noted on your written scope.
- Nikro dryer vent booster fans (inline models DV-100 and DV-200): The plastic impeller blades deform when subjected to lint-packed backpressure, common in Denver’s older Baker and Berkeley neighborhoods where 1970s duct routing includes multiple elbows. We pull the fan, photograph the blade distortion, and replace with an OEM Nikro impeller or a Guardsman metal-blade equivalent - your choice, priced in writing before we open the package.
- Nikro air scrubber HEPA housings (APS-500 series): The gasket channel warps if the unit’s stored hot-side-down in a Denver attic between jobs. We check gasket compression with a feeler gauge; a failed seal means the scrubber’s recirculating, not filtering. We replace the gasket set from Nikro parts stock or fabricate a field-fit from closed-cell foam - photographed, logged, and covered under our 365-Day Done Right Promise.
Our Nikro Air Duct Cleaning Process

- 1
Written price delivered first. Haven Standard Clause 1: we inspect access points, count duct runs and registers, and hand you a written price before a panel comes off. No exceptions.
- 2
Nikro equipment diagnostic. We test suction pressure, inspect seals and gaskets, and verify HEPA integrity on our Nikro gear - or note why we’re subbing Rotobrush or Abatement Technologies for your job.
- 3
Photo documentation of your system. The camera goes into every register, plenum (the central distribution box), and main trunk line before we touch anything. Here is what the camera found. Here is what it costs to fix it. You decide.
- 4
Negative-pressure extraction with source removal. We attach at the plenum, seal registers, and pull debris through the duct run toward the collection point - not blow it around with compressed air alone.
- 5
Post-clean verification and photo record. We re-photograph every run, deliver the before-and-after set as a standard job record, and test static pressure to confirm flow improvement.
- 6
365-Day Done Right Promise in writing. If the work’s not right, we make it right. The guarantee is a signed document, not a website claim.

Factors that increase cost: original galvanized duct runs in pre-1980 Denver homes (Capitol Hill, Wash Park) with rust scale and no access panels; rodent debris requiring sanitizing; collapsed flex duct needing repair before cleaning. We name the specific issue and price it in writing before starting. Call (720) 799-2292 for an exact quote - estimates are free.
Why Denver Homeowners Call CleanRun Duct Cleaning Denver for Nikro Work

We’ve been servicing Denver homes and businesses since 2013, including jobs in Capitol Hill where older furnace systems and original galvanized duct runs keep the work honest. Tomas Reyes, our owner, picked up his trade fundamentals at Manhattan’s Apex Technical School and has photographed every register, plenum, and main trunk line before and after a job since day one. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so if your Nikro equipment needs backup from a different manufacturer during a job, we don’t subcontract or delay. Every customer gets a Documented Photo Record, a written price before work starts, and the 365-Day Done Right Promise backed in writing.
FAQs
No. Routine air duct cleaning does not void Nikro equipment warranties, provided the work is performed by a qualified technician without altering factory components. As an independent Nikro service provider, we document our methods and equipment serial numbers in your job record so warranty claims remain straightforward. Call (720) 799-2292 if your warranty paperwork needs our service details.
We deliver a Documented Photo Record showing the inside of every duct run before and after, with timestamps and register labels. The difference between a cleaned galvanized trunk line and one that still holds debris is visible. If you don’t receive this record, the job isn’t complete.
Replace when repair exceeds 60% of replacement cost or when parts are discontinued - the SL1000 series, for example, has limited OEM support as of 2023. We quote both options in writing when applicable. Call (720) 799-2292 for a Free Second Opinion on any written estimate you’ve already received.
A typical Denver single-family home takes 3-5 hours for full supply and return cleaning with our Nikro negative-pressure equipment. Commercial jobs or homes with original ductwork in neighborhoods like Congress Park may run longer; we state the time estimate in your written scope before starting.
Every 3-5 years for most Denver homes, sooner if you’ve completed renovation, had rodent activity, or notice reduced airflow at registers. Homes near active construction in RiNo or the Central Park development often need more frequent service due to caliche dust infiltration. We inspect and advise without charge during any service call.
