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 Mount Prospect, IL
Most HVAC cleaning jobs in Mount Prospect run $380-$680 for a full system, with air quality and sanitizing work adding $220-$490 depending on whether we’re treating mold in flex duct or installing UV lights in an aging air handler. We’re CleanRun, and we’ve found that homes here need a different approach than newer suburbs because the ductwork itself is part of the problem. Call (224) 385-0904 for a written estimate before any work starts.
Mount Prospect’s housing stock is almost entirely 1953-1973 construction, ranch and split-level homes with galvanized steel trunk lines that were retrofitted for central AC decades later. The result is hybrid duct systems with spliced flex branches, makeshift plenums, and cloth-backed tape at joints that dried out twenty years ago. Our crews photograph every duct run before and after, and every job ships with a written price agreed upfront under Haven Standard Clause 1.
Why Mount Prospect Homes Are Different
The northwest Cook County climate puts these aging ducts through severe cycles. Six months of dry furnace heat from October through April, then high-humidity AC operation all summer. Condensation builds inside ductwork, especially in flex runs under slabs or through unconditioned attics, accelerating mold spore accumulation. Spring oak and maple pollen loads are heavy here, and leaky joints pull particulates from the mature tree canopy plus the I-90 corridor to the south.
In the Randhurst-area neighborhoods that filled in after 1962, we regularly find supply trunk joints still wrapped in crumbling Eisenhower-era cloth tape. Attic insulation fibers and decades of debris migrate straight into the supply air stream. These systems were engineered for forced-air heat alone, never designed for access or maintenance. Neighboring Palatine or Arlington Heights, developed more gradually, don’t have this concentration of two-era hybrid configurations.
Our Main Mount Prospect Services
Mount Prospect homeowners call us most often for these three services, each with its own dedicated page and local pricing.
Air Duct Cleaning in Mount Prospect
We clean the full duct system with negative-pressure extraction, photographing every run before and after. In Mount Prospect, this means addressing the debris traps created by retrofitted flex branches and separated tape joints. The photo record shows exactly what was removed from your galvanized steel trunks and spliced branches. Air Duct Cleaning in Mount Prospect covers full pricing and what’s included.
Dryer Vent Cleaning in Mount Prospect
Dryer vents in these postwar homes often run through exterior walls with original terminations that clog faster than modern installations. We clean the full vent path with rotary tools and verify airflow at termination. Every job includes a photo of the lint mass removed. Dryer Vent Cleaning in Mount Prospect has full details.
Duct Repair & Sealing in Mount Prospect
Separated tape joints and rusted steel seams are standard findings here. We seal with mastic and metal-backed tape, replace damaged flex branches, and photograph every repair.

BeforeAfterHVAC Cleaning in Mount Prospect
HVAC cleaning in Mount Prospect means working on equipment connected to duct systems that were never designed for central air. The evaporator coil sits in an air handler or furnace plenum that was retrofit-spliced into a 1960s heat-only configuration, and the blower pushes air through flex branches with irregular geometry that changes system static pressure. We see coils caked with debris that bypassed filters through leaky return plenums, and blowers coated in particulate that settled out during off cycles. HVAC Cleaning covers our full equipment scope.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or AC running continuously without reaching setpoint in July humidity.
What it costs in Mount Prospect
Evaporator coil cleaning typically runs $180-$340 depending on accessibility and contamination level.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water capture, and photograph before and after through the access panel.
Blower Cleaning
Signs you need it
Vibration at startup, uneven airflow room to room, or dust puffing from registers when the fan cycles on.
What it costs in Mount Prospect
Blower motor and wheel cleaning typically runs $160-$290.
How we do it
We remove the blower assembly, clean the wheel blades and housing with compressed air and solvent, check motor amp draw, and reinstall with photo documentation.
What HVAC Cleaning Costs in Mount Prospect
| Item | Typical range in Mount Prospect |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $160-$290 |
| Full HVAC cleaning (coil + blower + cabinet) | $380-$680 |
How do I know my coil is actually dirty?
We photograph the coil through the access panel before touching it; you see the debris buildup before we quote any work, and the after photo is delivered with your job record.
Can HVAC cleaning fix my AC keeping up in summer?
Dirty coils and blowers reduce capacity 15-30%, so cleaning often restores designed performance; if duct leakage is the primary cause, we’ll note that in your written estimate and recommend sealing.
Air Quality & Sanitizing in Mount Prospect
Air quality work in Mount Prospect addresses conditions created by fifty-year-old duct systems pulling attic air and slab moisture into the supply stream. The repeated condensation cycles in retrofitted flex branches create microclimates where mold establishes, and the village’s heavy spring pollen load infiltrates through joints that haven’t sealed in decades. We treat what’s growing, install prevention where the geometry allows, and document everything. Air Quality & Sanitizing covers our full treatment scope.
Mold Treatment
Signs you need it
Musty odor when the system cycles, visible spotting at registers, or family members with worsening allergies indoors in summer.
What it costs in Mount Prospect
Mold treatment with EPA-registered sanitizer typically runs $280-$450 for a standard ranch system.
How we do it
We apply Abatement Technologies-approved antimicrobial through the duct system with fogging equipment, treat the evaporator case and drain pan, and deliver lab-quality photo documentation of treated areas.
UV Light Installation
Signs you need it
Recurring mold after treatment, chronic musty odor from the air handler, or desire for continuous prevention in a high-humidity basement installation.
What it costs in Mount Prospect
UV-C lamp installation in the supply plenum typically runs $320-$580 including hardware.
How we do it
We mount a Guardsman or comparable UV-C lamp in the supply plenum downstream of the coil, wire to the blower circuit for automatic operation, and show you the installed position in your photo record.
What Air Quality & Sanitizing Costs in Mount Prospect
| Item | Typical range in Mount Prospect |
|---|---|
| Mold treatment (standard system) | $280-$450 |
| UV light installation | $320-$580 |
| Full air quality package (treatment + UV + filter upgrade) | $490-$890 |
Will mold come back after treatment?
Without fixing the moisture source, mold typically recurs 12-24 months; we identify the source in our written assessment and recommend UV or sealing if the geometry supports it.
Are UV lights worth the cost?
UV-C at the coil prevents biofilm buildup that reduces efficiency and recirculates spores; in Mount Prospect’s humid summer conditions, we see measurable improvement in odor and coil cleanliness at annual inspection.
