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 HVAC Cleaning in Littleton: What to Know First
CleanRun Duct Repair & Cleaning provides independent Aprilaire HVAC cleaning in Littleton, with most evaporator coil, blower, and air handler 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 the work performed. If you own an Aprilaire 5000, 600, or 800 series unit, or an Aprilaire air cleaner integrated with a Lennox, Trane, or Carrier system, we clean and restore it without voiding your OEM warranty. Call (720) 315-7291 for a free estimate with a written price delivered before we start.
How Aprilaire Products Fail - and How We Fix Them
- Model 5000 Electronic Air Cleaner: The ionizing wires and collection cells load with fine particulate faster in Littleton’s dry winter months when static electricity is high. We remove the cells, clean them with manufacturer-specified solution (never pressure-washed, which warps the aluminum), and test ionizer output before reassembly. A warped cell from improper prior cleaning is a common find in Ken Caryl Ranch homes.
- Model 600/600M Humidifier - Blower Wheel Contamination: The bypass humidifier dumps moisture directly into the supply plenum (the main trunk that carries heated air to your duct runs). When the water panel scales with Colorado’s hard water, mineral dust coats the blower wheel downstream, reducing airflow by 15-30%. We pull and clean the wheel, descale the humidifier, and photograph the blower vanes before and after.
- Model 800 Steam Humidifier - Heat Exchanger Scaling: The electrode canister generates steam through electrolysis, but Littleton’s water hardness exceeds 140 ppm. Calcium builds on the electrodes, then flakes into the air handler cabinet and onto the heat exchanger (the combustion chamber that separates flue gases from your breathable air). We descale the canister and vacuum the exchanger fins without dislodging factory brazing.
- Model 1210/2210/3210 Media Air Cleaner - Collapsed Filter Frames: The MERV 13 media is dense enough that homeowners in Columbine Knolls often run it past its rated life. The pleats sag, bypass unfiltered air at the gasket seals, and load the evaporator coil with debris that should have been captured. We replace the media with OEM Aprilaire 213 or 413 filters, then clean the coil if bypass has already occurred.
- Integrated Aprilaire on Variable-Speed Systems: When Aprilaire components are paired with modulating furnaces (common on Carrier Infinity and Trane XV systems), a dirty blower or restricted coil triggers false airflow faults. The board logs error codes that point to the motor when the real issue is debris load. We clean first, document pressure readings, and only then recommend parts replacement.
Our Aprilaire HVAC Cleaning Process

- 1
Inspection with camera: We feed a borescope through the return drop and into the plenum to show you debris load, coil condition, and any filter bypass before quoting. Tomas Reyes pulls the inspection camera before he quotes anything - the camera doesn’t negotiate, it just shows what’s there.
- 2
Written price on the spot: Using our printed price sheet, we deliver a flat rate for the scope of work. Haven Standard Clause 1: no verbal estimates, no per-vent add-ons, no surprises.
- 3
OEM or verified aftermarket parts decision: For Aprilaire media filters and water panels, we stock OEM. For consumables like humidifier solenoids, we use quality aftermarket equivalents that match spec and cost less - your choice, documented on the work order.
- 4
Negative-pressure extraction and contact cleaning: We seal the air handler, apply negative pressure to contain dislodged debris, and clean coils with foaming agent and soft brushes (never wire bristles on aluminum fins). Blower wheels are removed and cleaned outside the cabinet.
- 5
Performance verification and photo record: We measure static pressure before and after, run the system through its full sequence, and deliver before-and-after photos of every cleaned component as part of the standard job record.
- 6
365-Day Done Right Promise in writing: If the work is not right, we make it right. The guarantee is printed, not promised.

AfterWhat Aprilaire HVAC Cleaning Costs in Littleton
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Evaporator coil cleaning (Aprilaire-integrated system) | $280-$420 | Coil accessibility, fin corrosion, need for chemical restoration |
| Blower wheel and housing cleaning | $180-$290 | Wheel removal difficulty, bearing condition, housing liner damage |
| Heat exchanger cleaning (Model 800 series) | $340-$480 | Scale depth, need for combustion analysis after reassembly |
| Full air handler cleaning (coil, blower, cabinet, drains) | $520-$740 | System size, debris load, drain pan condition, filter bypass damage |
| Condenser cleaning (outdoor unit) | $160-$240 | Fins per inch count, refrigerant access requirements |
These are whole-system flat prices, not per-vent teaser rates that balloon once the truck arrives. Every estimate is free, written, and valid for 30 days. Call (720) 315-7291 and we’ll put our number next to any competitor’s written quote - Haven Standard: Free Second Opinion.
Why Littleton Homeowners Call CleanRun Air Duct Cleaning Littleton for Aprilaire Work

We’ve cleaned Aprilaire equipment in Littleton since 2013, including the older bypass humidifiers in Columbine Knolls where duct liners are fiberglass and fragile. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, which matters because Aprilaire components are often integrated with those brands - a technician who knows only one manufacturer’s control logic can misread a fault code or misdiagnose a sequence failure. Every job leaves with a documented photo record, and the 365-Day Done Right Promise is backed in writing, not subject to manager approval. We’re independently owned and operated, not a franchise, and Tomas Reyes still runs the inspection camera on jobs where the ductwork tells a longer story than the listing price suggests.
FAQs
No, if performed by a qualified technician using manufacturer-specified methods. As an independent Aprilaire service provider, we follow OEM cleaning procedures and document them, so warranty claims remain valid. We do not use pressure washers on electronic air cleaner cells or wire brushes on evaporator fins - both practices that Aprilaire and furnace manufacturers cite as warranty-voiding damage. Call (720) 315-7291 if you need documentation for a warranty claim.
OEM Aprilaire media (213, 413, 516) is engineered to the exact pleat depth and gasket compression for your cabinet. Aftermarket filters that match MERV rating but miss frame tolerances allow bypass, which is why we find collapsed coils in homes that “changed the filter regularly.” We stock OEM and will show you the fit difference before you decide. For a free estimate with filter replacement included, call (720) 315-7291.
You receive a documented photo record of every cleaned component - coil, blower wheel, heat exchanger, cabinet interior - as a standard deliverable, not an upsell. We also record static pressure readings before and after. If a company won’t show you the inside of your own air handler, you’re paying for vacuum noise. Call (720) 315-7291 for a job where the evidence comes with the invoice.
Often yes, but not always. A scaled water panel or clogged distribution tube reduces output even when the solenoid opens. In Littleton’s hard water, we replace the panel, descale the orifices, and check the humidistat calibration against an independent hygrometer. If the unit is correctly sized but poorly maintained, cleaning restores capacity. If it’s undersized for your home’s air changes, we’ll tell you that too - Haven Standard Clause 1 means we quote what you need, not what we sell. Call (720) 315-7291 for a diagnosis.
Evaporator coils and blower wheels: every 3-5 years in typical Littleton homes, sooner with pets or recent renovation. Aprilaire humidifiers: annual water panel replacement with descaling, full cleaning every 2-3 years. Electronic air cleaners: cell cleaning annually, more often in high-pollen seasons. The real answer depends on what the inspection camera shows - we don’t sell maintenance contracts, so we have no incentive to recommend work you don’t need. Call (720) 315-7291 for a free inspection and written recommendation.
