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.

AfterAir Duct Cleaning in Downers Grove, IL
HVAC cleaning in Downers Grove typically runs $320-$580 for a full system, and every job starts with a written price before we touch a single panel. Downers Grove’s concentration of 1950s-1970s ranch and split-level homes means we’re working with original galvanized ductwork that’s 50-70 years old, often with corrosion at joints and decades of accumulated debris that newer suburbs simply don’t see. Our crews coordinate scheduling from the Chicago office and serve Downers Grove locally. Call (224) 344-8881 for a free estimate.
Why Downers Grove Homes Are Different
Downers Grove’s explosive residential growth from the 1950s through the 1970s left a housing stock dominated by postwar ranches, raised ranches, and split-levels with original sheet-metal forced-air ductwork. In most cases, this ductwork has never been professionally cleaned. The basement-run trunk-and-branch systems common off Fairview Avenue and Belmont Road use galvanized sheet metal that corrodes and gaps at joints over time, allowing attic and crawl-space debris to migrate into living-area supply runs.
The humid continental climate here drives heavy HVAC runtime through high summer dew points and extended pollen seasons from DuPage County’s dense tree cover. Long, dry winters push residents to run humidifiers tied into ductwork, and improperly maintained bypass humidifiers on these older systems are a frequent source of mold growth inside return plenums. Split-level homes in the postwar neighborhoods have multi-level duct runs with short, angular offsets between floors that standard flex-line equipment struggles to navigate - local techs know to bring smaller-diameter brush rigs or risk leaving 90-degree transitions untouched.
Our Main Downers Grove Services
Most Downers Grove homeowners who call us start with one of these three services:
Air Duct Cleaning in Downers Grove
We clean the full supply and return network with negative-pressure extraction, photographing every duct run before and after. In Downers Grove, we regularly find construction debris from era renovations and fiberglass fiber shedding in original systems that have never been opened. Air Duct Cleaning in Downers Grove includes the documented photo record as standard.
Dryer Vent Cleaning in Downers Grove
Dryer vent blockages are common in these older homes where original vent routing through soffits or crawl spaces creates lint accumulation points. We clean the full run from appliance to termination with rotary brushes and verify airflow with a manometer. Dryer Vent Cleaning in Downers Grove includes a written scope and photo documentation.
Duct Repair & Sealing in Downers Grove
Original galvanized joints in Downers Grove homes gap and corrode after 50+ years of thermal cycling. We seal accessible leaks with mastic and mechanical fasteners, and replace damaged sections with code-compliant materials. Duct Repair & Sealing in Downers Grove starts with a written price for the full scope.

BeforeAfterHVAC Cleaning in Downers Grove
HVAC cleaning in Downers Grove addresses the accumulated load on components that have run continuously through humid summers and dry winters in homes with 50-70-year-old duct infrastructure. The evaporator coils, blowers, and condensers in these systems work harder than equivalent equipment in newer suburbs because leaky original ductwork pulls unconditioned attic and crawl-space air into the return side. HVAC Cleaning from CleanRun includes full component access, cleaning, and the documented photo record on every visit.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, reduced airflow at registers, or a musty odor when the AC first cycles on.
What it costs in Downers Grove
Evaporator coil cleaning typically runs $180-$340 depending on accessibility and contamination level.
How we do it
We remove the coil access panel, apply foaming cleaner from Abatement Technologies, rinse with low-pressure water, and photograph the before and after condition for the job record.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow room-to-room, or dust puffing from registers at startup.
What it costs in Downers Grove
Blower cleaning typically runs $150-$280 depending on motor type and debris buildup.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and soft brushes, balance the assembly, and document with photos before reinstallation.
What HVAC Cleaning Costs in Downers Grove
| Item | Typical range in Downers Grove |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $150-$280 |
| Full HVAC system cleaning (coil, blower, condenser) | $320-$580 |
How do I know my HVAC components were actually cleaned?
Every HVAC cleaning includes a Documented Photo Record of each component before and after, delivered as part of the standard job record - not a verbal report, photographs you can review. Call (224) 344-8881 to schedule.
Why does my old Downers Grove system need HVAC cleaning more often?
Original ductwork leaks pull unfiltered attic and crawl-space air into the return, loading coils and blowers with debris that sealed modern systems never see. Call (224) 344-8881 for an inspection and written price.
Air Quality & Sanitizing in Downers Grove
Air quality and sanitizing in Downers Grove targets the biofilm and allergen accumulation that thrives in 50-70-year-old ductwork during humid summers, plus the mold growth from improperly maintained humidifiers common in these postwar systems. The extended pollen seasons from DuPage County tree cover and turf drive particulate load that standard filtration misses. Air Quality & Sanitizing from CleanRun includes application with trade-verified products and full documentation.
Mold Treatment
Signs you need it
Visible mold at registers or in the return plenum, a persistent musty odor when the system runs, or recent water intrusion from a humidifier leak.
What it costs in Downers Grove
Mold treatment typically runs $280-$520 depending on affected duct length and accessibility.
How we do it
We apply an EPA-registered antimicrobial through the duct network using a fogging system, treat affected surfaces with a contact spray, and verify with post-treatment photos.
UV Light Installation
Signs you need it
Recurring mold or biofilm after cleaning, allergy symptoms that spike when the HVAC runs, or a system in a damp basement with chronic humidity.
What it costs in Downers Grove
UV light installation typically runs $340-$620 depending on lamp wattage and whether the installation requires a new electrical circuit.
How we do it
We mount a UV-C lamp in the supply plenum near the coil, wire to the blower circuit for automatic operation, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Downers Grove
| Item | Typical range in Downers Grove |
|---|---|
| Mold treatment | $280-$520 |
| UV light installation | $340-$620 |
| Full air quality package (treatment + UV + filter upgrade) | $520-$890 |
Is mold in my ducts common in older Downers Grove homes?
Yes - we find mold in return plenums on roughly one in three Downers Grove jobs, usually from humidifier leaks or summer condensation in uninsulated basement trunk lines. Call (224) 344-8881 for an inspection and written price.
Will UV lights actually prevent mold from coming back?
UV-C lamps inhibit mold and biofilm growth on the coil and in the plenum when properly sized and maintained, but they don’t clean existing debris - we treat first, then install. Call (224) 344-8881 to discuss your system.
