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.
Aprilaire Air Duct Cleaning in Littleton: What to Know First
CleanRun Duct Repair & Cleaning provides independent Aprilaire air duct cleaning in Littleton, with most residential systems completed in a single scheduled visit and a written price delivered before any panel comes off. We are not affiliated with or authorized by Aprilaire; we are an independent Aprilaire service provider that documents every duct run with before-and-after photos and backs the work with a 365-Day Done Right Promise. If you own an Aprilaire whole-home air cleaner, humidifier, or ventilation system and need the connected ductwork cleaned, inspected, or resealed, call (720) 315-7291 for a free estimate with a written price.
How Aprilaire Products Fail - and How We Fix Them
- Model 5000 Electronic Air Cleaner: The ionizing wires and collection cells load up with fine particulate faster than passive media filters, and when the ductwork behind the unit is dirty, that debris recirculates through the cells and accelerates corrosion. We remove the cells, clean the full supply plenum (the sheet-metal box that distributes air to your duct runs), and photograph the cell contact points so you can see whether replacement is needed or cleaning will suffice.
- Model 600/700 Humidifier Series: The water panel evaporates into the supply duct, and any existing biofilm or dust buildup in that duct run absorbs moisture instead of letting it reach your rooms. The result is a humidifier that runs constantly but delivers static-shock winters. We negative-pressure extract (vacuum under suction so debris doesn’t escape into the home) the affected supply run and treat the humidifier pad frame for scale, then show you the photo of the duct before the pad goes back in.
- Model 8126X Ventilation System: This heat-recovery ventilator pulls outdoor air through dedicated ductwork that most Littleton homeowners never think to clean. The incoming line runs through attic or crawl space, and in our climate that means temperature swings that loosen mastic and let insulation fibers enter the fresh-air stream. We inspect the HRV duct runs with a camera, reseal joints where needed, and document the interior condition - the camera doesn’t negotiate, it just shows what’s there.
- Model 1910/1925 Dehumidifier: The return duct feeding these units is often undersized in older Littleton homes, especially in Columbine Knolls where 1970s ranch builds have 14-inch returns trying to serve a whole basement. The dehumidifier works harder, the duct loads with condensate-attracted debris, and airflow drops until the unit faults on high head pressure. We clean the return, measure static pressure, and tell you whether the duct size is the real problem or just the dirt.
- Model 1210/2210/3210 Media Air Cleaner Cabinets: The MERV 16 filters are excellent, but homeowners who upgrade from a cheap fiberglass filter often don’t realize the existing ductwork was never sealed to handle that airflow resistance. The cabinet gasket leaks, the filter bypasses dirty air, and the duct behind it never gets cleaner. We clean the full system, reseat the cabinet with proper gasket compression, and test for bypass with a smoke pencil - then photograph the seal so you have proof it was done.
Our Aprilaire Air Duct Cleaning Process

- 1
Camera inspection before quote. Tomas Reyes or a CleanRun technician feeds a borescope through the main trunk and at least two branch runs to show you debris load, flex duct condition, and any seal gaps. The footage determines scope, not a flat-rate card.
- 2
Written price delivered. Haven Standard Clause 1: the price is written and agreed before work starts. No per-vent add-ons, no “we found more” surprises. The price covers the full system described.
- 3
Equipment selection by system type. Aprilaire-connected ductwork with electronic air cleaners gets Rotobrush contact cleaning for the cell-adjacent surfaces; humidifier supply runs with heavy biofilm get Nikro HEPA-contained negative-pressure extraction. We name what we’re using and why.
- 4
Component-aware cleaning. We remove or protect Aprilaire media, cells, and water panels per manufacturer handling specs - no harsh chemicals on electronic components, no overspray on humidistat sensors.
- 5
Post-clean test and photo record. Every duct run is photographed after cleaning and delivered as part of your job record. We verify airflow at key registers and note any remaining issues (damaged flex, disconnected boots) with a separate written option if you want them addressed.
- 6
365-Day Done Right Promise in writing. If the work isn’t right, we make it right. The promise is printed, not verbal, and tied to your photo record for reference.

Price moves based on system accessibility (crawl space vs. basement), debris density measured during camera inspection, and whether the Aprilaire component itself needs removal and reinstallation. We also service Lennox, Trane, and Carrier systems with the same written-price standard.

Why Littleton Homeowners Call CleanRun Duct Repair & Cleaning for Aprilaire Work

We’ve cleaned ductwork in Littleton since 2013, including plenty of jobs in Columbine Knolls where the homes are older and the duct liners tell a longer story than the listing price suggests. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they carry printed price sheets because the number shouldn’t change based on who answers the phone. Every Aprilaire job gets the same documented photo record as every other - 52,000 homes and counting, every one with proof of work, not just a receipt. Equipment on the truck includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands you can look up before we start.
FAQs
No. Routine maintenance including duct cleaning does not void the Aprilaire product warranty, provided the work does not damage the unit. We remove electronic cells and media per manufacturer handling guidelines and document their condition photographically. If your Model 5000 cells show corrosion beyond cleaning, we’ll show you and note whether replacement is warranty-eligible based on age. Call (720) 315-7291 if you want us to review your warranty paperwork during the estimate.
For electronic cells and water panels, OEM Aprilaire parts fit and perform predictably. For gasket and hardware replacements during duct resealing, quality aftermarket equivalents from Guardsman meet the same specs at lower cost - we stock both and explain the trade-off before you decide. The photo record shows what was installed where.
Every duct run is photographed before and after, and those images are delivered as part of your standard job record. You see the debris load at the first elbow, the condition of the flex duct behind your Aprilaire cabinet, and the post-clean surface. This is not an upsell - it is included on every visit, a practice we’ve held since 2013.
Most scheduled appointments include inspection, written price, and cleaning in one visit if you approve the scope. We do not promise same-day dispatch for calls that come in unscheduled - duct cleaning is a booked job, and we allocate time to do it without rushing. Call (720) 315-7291 to book; estimates are free.
Usually the ducts. In Littleton’s dry climate, an undersized or debris-loaded supply duct can’t move enough moisture-laden air before it recondenses on the duct walls. We measure airflow and inspect with a camera to determine whether cleaning solves it or duct resizing is the real fix. The written price covers whichever scope we agree on.
