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.
Honeywell Air Duct Cleaning in Denver: What to Know First
CleanRun provides independent Honeywell 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 panel comes off. Our crews service Honeywell whole-house air cleaners, electronic air cleaners, and integrated media filters as part of a complete duct cleaning, not as an add-on. Typical turnaround from call to completion is 3-5 business days, with same-week scheduling available for most Denver metro addresses.
This page is for Honeywell owners in Capitol Hill, Cherry Creek, Wash Park, and surrounding Denver neighborhoods who want to know what the work actually involves, what it costs, and how to verify it was done right. Call (720) 799-2292 for a written estimate at no charge.
How Honeywell Products Fail - and How We Fix Them
- F50 Electronic Air Cleaner power supply failure. The F50 series uses a high-voltage power pack to charge internal cells, and after 8-12 years in Denver’s dry climate, the transformer windings crack from thermal cycling. When the power pack fails, the cells stop charging and particulate passes straight through. We test output voltage at the cell contacts, replace with OEM or equivalent power packs from Honeywell’s current F300/F100 line where compatible, and photograph the cell condition before reinstallation.
- F100 Media Air Cleaner bypass leakage around collapsed filter frames. The F100’s pleated media filter sits in a track that warps when homeowners install off-size aftermarket replacements, common in Denver’s older Baker and Highland neighborhoods where furnace closets run hot. Bypass air carries unfiltered debris into the ductwork, accelerating buildup in supply runs. We measure track squareness, replace with Honeywell-spec FC100A or verified cross-reference media, and seal gaps with aluminum tape rated for the plenum temperature.
- F300 Electronic Air Cleaner cell corrosion from humidifier overspray. In Denver homes with whole-house humidifiers mounted downstream of the F300, calcium-rich mist plates the cell plates and shorts the ionizing wires. The F300’s cell assembly was not designed for wet environments, and Honeywell’s own installation bulletins warn against this configuration. We remove and clean cells with manufacturer-approved solution, relocate humidifier supply where possible, and document cell gap spacing with feeler gauges before reassembly.
- TrueCLEAN whole-house air cleaner pressure drop causing blower strain. The TrueCLEAN (FGC series) uses a dense MERV 15 media that loads quickly in Denver’s spring pollen season, especially with cottonwood fluff from the South Platte corridor. Restricted airflow overheats PSC blowers and trips limit switches in Honeywell and non-Honeywell furnaces alike. We measure static pressure across the cabinet, clean or replace media per Honeywell’s 6-12 month schedule, and check blower amp draw against the furnace nameplate.
- Return duct contamination from F50/F300 cell wash residue. Homeowners who self-clean cells in a utility sink often reinstall them damp, and the residual rinse water captures lint and dust from the airstream, depositing it in the first elbow downstream. We’ve pulled 2-inch matting from return plenums in Park Hill homes where this went unaddressed. We remove the deposit mechanically, verify cell dryness with a moisture meter, and photograph the duct interior before closing.
Our Honeywell Air Duct Cleaning Process

- 1
System identification and scope. We record the Honeywell model number, serial date code, and furnace pairing. A 2019 F300A mounted on a 90% furnace in Stapleton requires different handling than a 2007 F50 on an 80% unit in Montclair.
- 2
Written price delivery. Before any work begins, we provide a fixed price for the complete scope under Haven Standard Clause 1. The price covers the full system, not per-vent arithmetic.
- 3
Component removal and condition documentation. Cells, media, or prefilters come out; we photograph each and note part numbers for the job record. If the power pack tests below 8 kV, we flag replacement.
- 4
Negative-pressure extraction of all duct runs. We attach a Nikro or Abatement Technologies HEPA collector to the main trunk and run Rotobrush contact cleaning through every supply and return, including the plenum and boots. The camera goes in first; the brush follows.
- 5
Component reinstallation and operational test. Honeywell cells are verified dry, media is seated square in the track, and the system runs through a complete heating cycle. We measure temperature rise and static pressure against baseline.
- 6
Deliverables. The customer receives the written scope, before-and-after photos of every duct run, and the 365-Day Done Right Promise in writing.

AfterWhat Honeywell Air Duct Cleaning Costs in Denver
| Service | Typical Range |
|---|---|

| Commercial Honeywell-integrated system cleaning | $1,200 - $2,400 |
Price moves with system size (square footage and register count), accessibility (crawlspace vs. basement furnace), and whether the electronic air cleaner requires cell replacement or power pack rebuild. We do not quote per-vent; the price is for the complete system, agreed in writing before work starts.

Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and arrives with the equipment roster published on our site, including Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman tools.
Tomas Reyes, our owner, still photographs every register, plenum, and main trunk line before and after, a practice from his years in Queens apartment buildings that hasn’t changed. Here is what the camera found. Here is what it costs to fix it. You decide.
FAQs
No, routine maintenance including cell cleaning and media replacement does not void Honeywell’s product warranty, provided the work follows manufacturer procedures and uses specified parts. We document part numbers and cleaning methods in the job record for warranty support if needed. Call (720) 799-2292 if you need warranty documentation for a claim.
OEM Honeywell media (FC100A series for F100 cabinets, FC2400 for TrueCLEAN) guarantees fit and pressure-drop specifications; quality aftermarket cross-references exist but require verification of MERV rating and frame dimensions. We stock both, name the manufacturer on the written scope, and warrant either for 365 days under our Done Right Promise.
Every CleanRun job includes a Documented Photo Record of every duct run, delivered as a standard deliverable, not an extra. The photos show the interior condition before brush contact and after extraction, with timestamps. If we cannot show you what was in your ducts, the job is not complete.
F50 and F300 units under 15 years with intact cell assemblies are typically worth power pack or cell replacement; beyond that, conversion to an F100 media cabinet often makes sense, especially given Honeywell’s reduced electronic air cleaner parts availability for pre-2010 units. We assess cell gap, plate condition, and power output, then quote both paths in writing.
Every 3-5 years for most Denver homes, sooner with pets, recent renovation, or cottonwood proximity near the South Platte or Cherry Creek. The F100 media filter itself requires replacement every 6-12 months depending on the FC100A size and household conditions. We note the recommended interval on the written scope and schedule a reminder if requested.
