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 Quality & Sanitizing in Denver: What to Know First
We provide independent Aprilaire air quality and sanitizing services in Denver, with most residential jobs completed in a single scheduled visit. Every job starts with a written price before any work begins, and every duct run is photographed before and after so you can see what was actually removed. For Aprilaire owners dealing with persistent odors, visible mold, or recurring allergy symptoms, we offer mold treatment, bacteria sanitizing, UV light installation, and whole-home air purifier integration.
This page is for Denver homeowners who own an Aprilaire system and need to know whether their air quality problem is a filter issue, a duct contamination issue, or a failed component in the air cleaner itself. Call (720) 799-2292 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 collect a conductive film of oil and particulate that arcing cannot burn off. In Denver’s dry winter air, the static buildup accelerates wire corrosion. We remove the unit, clean the ionizing assembly with a non-residue solvent safe for OEM components, and test voltage output at each cell before reinstallation. If the power supply reads below 6.2 kV, we replace it with an OEM Aprilaire part rather than a universal aftermarket unit that voids the remaining warranty.
- Model 2410 and 1410 Media Cleaners: The pleated media cabinet seals degrade where the door meets the housing, allowing bypass air that the homeowner never sees. We find this during camera inspection of the return plenum, the box that distributes air into the furnace. Our fix is a genuine Aprilaire gasket kit, not weatherstrip tape, because the specified compression seal maintains rated MERV 11 efficiency.
- Model 800 Steam Humidifier: Electrode chambers scale with Denver’s hard water, but the real air quality hit comes when standing water breeds bacteria that the fan then distributes. We descale with manufacturer-specified citric acid cycles, replace the canister if electrode wear exceeds 30 percent, and apply a bacteria sanitizing treatment to the downstream ductwork. The camera shows the biofilm before we start. Here is what the camera found. Here is what it costs to fix it. You decide.
- Model 1210 and 2210 Bypass Humidifiers: The water panel evaporates incompletely in low-humidity conditions, leaving mineral deposits that harbor mold in the bypass duct. We see this in Capitol Hill homes with original galvanized duct runs where the panel sits undisturbed for multiple seasons. Our protocol includes panel replacement, bypass duct cleaning with negative-pressure extraction, and a mold-inhibiting treatment applied to the interior surfaces.
- Model 1870 and 1850 Dehumidifiers: The condensate drain line traps organic matter that produces musty odors even when the unit appears functional. We clean the drain trap with pressurized nitrogen, treat the coil housing with a non-corrosive sanitizer, and install a UV-C lamp at the supply plenum if the homeowner has recurring bacterial issues. The 1870’s vertical configuration in Denver basements makes this trap particularly prone to stagnation.
Our Aprilaire Air Quality & Sanitizing Process

- 1
System identification and written price. We record the Aprilaire model, serial number, and installation date, then deliver a written price before any panel comes off. Haven Standard Clause 1.
- 2
Camera inspection of the full duct network. Every register, plenum, and main trunk line is photographed. We show you the 3-inch debris build-up at the first elbow, not tell you about it.
- 3
Component-specific diagnosis. We test voltage on electronic air cleaners, measure electrode wear on steam humidifiers, and pressure-test bypass dampers. Parts decision follows: OEM Aprilaire when warranty coverage applies, quality aftermarket only when the customer understands the trade-off.
- 4
Treatment execution. Mold treatment, bacteria sanitizing, or odor removal is applied with equipment sized to the duct volume, not a fogger from a hardware store. We use Abatement Technologies and Nikro negative-pressure systems matched to the job.
- 5
Post-treatment verification. The camera runs again. Every after photo is time-stamped and delivered with the job record. We test airflow at the registers and verify the Aprilaire unit operates within manufacturer spec.
- 6
Written guarantee delivery. The 365-Day Done Right Promise is printed and signed before we leave. Haven Standard Clause 5.

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

We’ve serviced Aprilaire equipment in Denver 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.
The 365-Day Done Right Promise is backed in writing, not subject to manager approval. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so we can diagnose whether the air quality issue is the Aprilaire component or the host HVAC system behind it. Every job includes a Documented Photo Record delivered as a standard deliverable, not an upsell.
FAQs
No, routine maintenance and repair by an independent service provider does not void your Aprilaire warranty, provided OEM parts are used where specified and the work is documented. We are an independent Aprilaire service provider, not affiliated with or authorized by Aprilaire, and we record serial numbers and part numbers for every component we touch so your warranty file stays complete. Call (720) 799-2292 if you need documentation for a warranty claim.
You receive a time-stamped photo record of every duct run before and after treatment, plus a written scope of what was applied and where. We do not ask you to trust a smell or a promise. The camera shows the biofilm location and the post-treatment surface condition. If the results don’t match the scope, Haven Standard Clause 5 applies.
Repair makes sense when the power supply and cells test within 80 percent of spec and the cabinet is structurally sound. Replacement is the better value when multiple cells have failed, the cabinet is warped from heat cycling, or you’re already planning HVAC replacement and want a matched system. We put both numbers in writing before you decide. Call (720) 799-2292 for a free second opinion on any estimate you’ve already received.
The $79 coupon model typically covers a shop-vac at the register and a bill for “additional services” once the truck is in your driveway. Our price is the full price for the full system, written before we start. The photo record proves the difference between vacuum noise and actual negative-pressure extraction with professional equipment from Rotobrush, Nikro, and Abatement Technologies.
Most Denver homes benefit from duct sanitizing every three to five years, but Aprilaire humidifiers and electronic air cleaners should be inspected annually because our dry climate and hard water accelerate scale and debris buildup. Homes with pets, recent construction, or occupants with respiratory conditions may need more frequent treatment. We do not sell maintenance contracts; we photograph the condition and let you see whether it’s time.
