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.
Air Duct Cleaning in Downers Grove, IL
HVAC cleaning in Downers Grove typically runs $400-$750 for a full system, with most jobs scheduled within a week of the call. We dispatch crews from our Chicago office to handle the village’s distinctive mix of post-war ranch homes with original sheet-metal ductwork and the pollen load from one of DuPage County’s densest urban forests. Call (331) 236-5490 for a written price before any work starts.
Why Downers Grove Homes Are Different
Downers Grove earned Tree City USA recognition decades ago, and the mature canopy of oaks, cottonwoods, and elms in neighborhoods like Lester and Randall Parks produces pollen and fluff that smaller, newer suburbs simply do not match. Late May brings cottonwood seed release that packs outdoor condenser coils and clogs older return grilles within days.
The housing stock reinforces the problem. Thousands of ranch, split-level, and Cape Cod homes built from the late 1940s through the early 1970s still run their original bare sheet-metal or early fiberglass-lined ductwork. Mastic joints have dried and loosened over 50-plus years. Return-side leaks pull basement dust and insulation particles into living spaces. In summer, humid air moving through unconditioned basement ducts creates conditions for moisture migration and mold colonization on degraded duct liner.
Our Main Downers Grove Services
Downers Grove homeowners most often call us for these three services:
Air Duct Cleaning in Downers Grove
We clean the full trunk-and-branch system, from plenum to register, using negative-pressure extraction with Rotobrush and Nikro equipment. In Downers Grove’s older homes, we regularly find 2-3 inches of compacted debris at the first elbow downstream of the air handler, plus deteriorating fiberglass liner shedding visible fibers. Every run is photographed before and after. Air Duct Cleaning in Downers Grove

Dryer Vent Cleaning in Downers Grove
Dryer vent blockages are common in the village’s mid-century homes with original through-wall venting that was never designed for modern dryer airflow. We clear the full run with rotary brushes and airflow verification, documenting the before-and-after with photos. Dryer Vent Cleaning in Downers Grove

Duct Repair & Sealing in Downers Grove
Original sheet-metal systems in Downers Grove’s 1950s-1970s housing stock develop loosened joints, disconnected runs, and degraded liner. We seal with mastic and mechanical fasteners, replace damaged sections, and photograph every repair. Duct Repair & Sealing in Downers Grove

AfterHVAC Cleaning in Downers Grove

Full HVAC Cleaning in Downers Grove addresses the village’s specific conditions: original equipment running 50-plus years in homes with mature-tree pollen loads and humid continental climate stress. We regularly photograph evaporator coils caked with cottonwood fluff and blower assemblies coated in fine dust pulled through degraded return ductwork. The job covers the full air path so the system does not recontaminate itself in the first heating cycle.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or musty odors when the AC first cycles on.
What it costs in Downers Grove
Evaporator coil cleaning typically runs $180-$320 in Downers Grove.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the before and after condition.
Blower Cleaning
Signs you need it
Vibration noise from the air handler, uneven heating or cooling between rooms, or dust puffing from registers at startup.
What it costs in Downers Grove
Blower assembly cleaning typically runs $150-$280 in Downers Grove.
How we do it
We remove the blower housing, clean the wheel and motor housing with compressed air and solvent, balance the assembly, and document with photos.

Why does my Downers Grove home need HVAC cleaning more often than newer suburbs?
The combination of 50-plus-year-old ductwork, mature-tree pollen, and original equipment running harder than designed pulls more debris through the system. Call (331) 236-5490 for an exact quote - estimates are free.
Air Quality & Sanitizing in Downers Grove

Air Quality & Sanitizing in Downers Grove targets the moisture and allergen problems specific to the village’s older housing stock. Humid summers push dew points into uncomfortable territory, and unconditioned basement return ducts in 1960s ranches create microclimates where mold colonizes interior liner surfaces. We treat the source, not the symptom, with documented before-and-after photo records.
Mold Treatment
Signs you need it
Musty odors when the system cycles, visible spotting on duct liner, or elevated humidity readings in basement return paths.
What it costs in Downers Grove
Mold treatment for affected duct runs typically runs $300-$550 in Downers Grove.
How we do it
We apply EPA-registered antimicrobial through the full affected run, mechanically remove visible growth, and verify with post-treatment photos.
UV Light Installation
Signs you need it
Recurring mold or biofilm after cleaning, or chronic musty odors that return within one season.
What it costs in Downers Grove
UV-C light installation at the coil or air handler typically runs $350-$600 in Downers Grove.
How we do it
We mount a Honeywell or Aprilaire UV lamp at the coil surface, wire to the blower circuit, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Downers Grove
| Item | Typical range in Downers Grove |
|---|---|
| Mold treatment (per affected zone) | $300-$550 |
| UV-C light installation | $350-$600 |
| Full air quality package (mold treatment + UV + sanitizing) | $600-$950 |
Is mold in my ducts common in Downers Grove?
Yes, the combination of humid summers and unconditioned basement returns in older homes creates conditions we treat regularly. Call (331) 236-5490 for an exact quote - estimates are free.
Will UV lights eliminate all my air quality problems?
UV-C controls biofilm at the coil but does not remove particulates; we pair it with source removal for complete results. Call (331) 236-5490 for an exact quote - estimates are free.
