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 HVAC Cleaning in Denver: What to Know First
CleanRun provides independent Honeywell HVAC cleaning in Denver, with most evaporator coil, blower, and condenser jobs completed in a single scheduled visit. We deliver a written price before any panel comes off, and every job ends with a Documented Photo Record of what we found and what we removed. Typical Honeywell HVAC cleaning in Denver runs $340-$780 for a complete system, depending on which components need attention and how accessible the air handler is. This page is for homeowners running Honeywell systems in neighborhoods like Capitol Hill, Wash Park, and Stapleton, where we’ve cleaned enough of these units to know which model lines collect debris where. Call (720) 799-2292 for a written estimate.
How Honeywell Products Fail - and How We Fix Them
- Comfortmaker / Tempstar cross-platform coils (used in Honeywell-integrated systems) - The aluminum fins on these coils laminate with a greasy, gray film that standard rinse methods won’t lift. We see this in Denver’s dry climate where indoor relative humidity drops below 25% in winter, causing electrostatic dust adhesion that bonds to condensate residue. Our fix: foaming cleaner with a dwell period, followed by low-pressure rinse and fin comb inspection. The camera shows the difference.
- Honeywell TrueEASE humidifier pads in bypass configurations - These pads scale hard in Denver’s moderately hard water (typically 6-8 grains per gallon). Scale bridges across the evaporative surface, forcing the blower to work harder and depositing mineral dust downstream into the duct run. We replace the pad with an OEM or compatible aftermarket equivalent, descale the distribution tray, and photograph the blower wheel for debris transfer.
- Lyric T6 Pro Wi-Fi thermostat-connected air handlers - The T6’s aggressive fan-cycling algorithm can keep blowers running at low speed for hours, causing fine dust to bypass the filter media and plate onto the blower squirrel cage. We remove the cage, clean it in a contained wash station, and check the filter bypass gap. In Park Hill last March, we found a T6-connected unit with 3/8-inch buildup that the homeowner didn’t know existed until the photo.
- Honeywell FC40R and FC100A media cabinet systems - These cabinets seal poorly when the filter is replaced with off-size aftermarket media, creating a bypass stream that soils the evaporator coil directly. We clean the coil, verify cabinet seal integrity, and note the correct filter size on the written job record so the next replacement doesn’t undo our work.
- Pre-2015 HW7500 and HW9000 series electronic air cleaners - The ionizing wires in these units foul with a conductive grease layer that reduces collection efficiency to near zero. Homeowners think the “click” means it’s working; often it’s just arcing across dirty wires. We clean the cells in a dedicated solution bath, test ionization current with a field meter, and document the before/after readings.
Our Honeywell HVAC Cleaning Process

- 1
System shutdown and access assessment. We locate the Honeywell air handler or furnace, verify model and serial numbers, and identify any warranty stickers that would be voided by non-OEM part substitution. Haven Standard Clause 1 applies: written price before any work starts.
- 2
Component photography. Every blower wheel, coil face, heat exchanger header, and plenum interior is photographed before contact. Here is what the camera found. Here is what it costs to fix it. You decide.
- 3
Targeted cleaning with trade-appropriate chemistry. Foaming cleaner for aluminum coils, contained wash for blower assemblies, wire-specific solution for electronic air cleaner cells. We use Rotobrush and Nikro equipment, and where Honeywell OEM cleaner is specified for warranty retention, we note the part number on the invoice.
- 4
Parts decision and replacement. If a humidifier pad, filter gasket, or ionizing wire set is needed, we show you OEM and quality aftermarket options with the price difference in writing. No selection is made without your initials.
- 5
Operational test and final photography. We run the system through a complete heat/cool cycle, measure temperature split, and photograph the cleaned components. The Documented Photo Record is delivered as a standard job deliverable, not an extra.
- 6
Written guarantee delivery. The 365-Day Done Right Promise is printed, signed, and left with you. Haven Standard Clause 6.

Why Denver Homeowners Call CleanRun Air Duct Cleaning Denver for Honeywell Work

We’ve cleaned Honeywell systems in Denver since 2013, including the original galvanized duct runs in Capitol Hill Victorians where a modern air handler has been shoehorned into a 1920s basement. Tomas Reyes and our crew know the difference between a TrueEASE pad that needs replacement and a distribution tray that needs descaling, and we photograph both so you can see why the work was recommended. The 365-Day Done Right Promise means if a cleaned coil shows residue or a blower rebalances within a year, we return under the written guarantee. We also service Lennox, Trane, and Carrier systems, so multi-zone homes with mixed brands get consistent documentation across every unit. Background-checked, uniformed technicians. License number published on every estimate. No call for a quote, no manager approval required for warranty claims.
FAQs
No, professional cleaning does not void a Honeywell warranty, but using non-OEM replacement parts without documentation can. We record every part number and cleaning method on your invoice so warranty coverage remains intact. As an independent Honeywell service provider, we have no manufacturer affiliation, but we follow warranty-safe practices. Call (720) 799-2292 if you need a copy of your warranty terms reviewed before scheduling.
You receive a Documented Photo Record of every component we touched, before and after, as a standard deliverable on every job. Haven Standard Clause 4. If a company won’t show you the inside of your own blower assembly, they didn’t clean it. Call (720) 799-2292 and we’ll explain what the photo record includes.
The $79-$129 offers typically cover a visual inspection and a shop vacuum at the register, not component-level cleaning of your coil, blower, or condenser. A proper Honeywell HVAC cleaning requires contained chemistry, contained wash stations, and reassembly with torque-specified fasteners. We put the full scope and price in writing before starting. Call (720) 799-2292 for a free second opinion on any written estimate.
Replace when the heat exchanger is cracked, the compressor has failed, or repair costs exceed 40% of replacement value. Clean when components are functional but efficiency has dropped due to debris buildup. We assess both paths and give you the numbers for each. Call (720) 799-2292 for a written evaluation.
Every 3-5 years for most Denver homes, sooner if you have pets, recent renovation dust, or run a humidifier year-round. The dry climate and seasonal wildfire smoke we’ve seen in recent years accelerate fin fouling on outdoor condensers. We note the recommended interval on your job record. Call (720) 799-2292 to schedule or set a reminder.
