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
HVAC cleaning in Mount Prospect typically runs $350-$650 for a full system, with air quality and sanitizing services adding $200-$500 depending on whether mold treatment or UV installation is needed. Most jobs in this northwest Chicago suburb require extra attention to aging sheet-metal ductwork from the 1955-1972 buildout era, where half a century of debris accumulation meets modern high-efficiency equipment. Call (224) 344-8881 for a written estimate before any work begins.
Why Mount Prospect Homes Are Different
Mount Prospect’s residential buildout happened fast and all at once, roughly 1955 to 1972, which means entire neighborhoods share the same vintage of ranch and split-level homes with original sheet-metal duct systems now pushing 50-70 years old. Many of these systems have never been professionally cleaned since installation. Our crews regularly encounter octopus-style plenum systems in the older subdivisions, loaded with accumulated debris and deteriorating fiberglass insulation particles from the original duct liner. The hot, humid summers common to the northwest Chicago suburbs promote mold colonization inside ductwork, especially in the low-clearance crawl-space trunk lines typical of Mount Prospect ranches, while the extended heating season from November through March accelerates particulate loading. We’ve also found that HVAC contractors in the 1990s and 2000s often routed new high-efficiency furnace venting through existing duct chases, leaving disconnected legacy branches sealed behind drywall that trap debris and mold without any visible access point.
Our Main Mount Prospect Services
Homeowners in Mount Prospect call us most often for these three services, each with its own dedicated page:
Air Duct Cleaning in Mount Prospect
Full-system air duct cleaning for Mount Prospect’s aging postwar housing stock, using negative-pressure extraction and rotary brush systems to remove debris from original sheet-metal runs and later flex-duct additions. We photograph every duct run before and after, and every job starts with a written price under Haven Standard Clause 1. Air Duct Cleaning in Mount Prospect covers the complete process for homes here.
Dryer Vent Cleaning in Mount Prospect
Dryer vent cleaning addresses lint buildup that restricts airflow and creates fire risk, especially important in Mount Prospect’s older homes where vent routing through finished basements or multiple stories complicates access. We inspect the full vent path with a camera when needed and provide before-and-after documentation. Dryer Vent Cleaning in Mount Prospect details what we find and how we clear it.
Duct Repair & Sealing in Mount Prospect
Duct repair and sealing fixes the disconnected branches, deteriorating seams, and failed tape joints common in Mount Prospect’s original 1950s-1970s systems, plus the leak points created where flex-duct was spliced into aging sheet-metal during later HVAC upgrades. Duct Repair & Sealing in Mount Prospect explains our repair methods and the photo documentation included.

BeforeAfterHVAC Cleaning in Mount Prospect
Mount Prospect’s climate and housing stock make HVAC cleaning a genuinely necessary maintenance item rather than an optional service. The combination of 50-70-year-old original duct systems, extended winter heating seasons that load components with particulates, and humid summers that foster biological growth means evaporator coils, blowers, and air handlers here work harder and get dirtier than in newer construction markets. HVAC Cleaning covers our full methodology; below is what Mount Prospect homeowners specifically need to know.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or a musty smell when the AC first cycles on in summer.
What it costs in Mount Prospect
Evaporator coil cleaning in Mount Prospect typically runs $180-$320, with access difficulty through tight plenum spaces in older ranches sometimes pushing toward the higher end.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the coil condition before and after for the job record.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating across rooms, or dust puffing from registers when the system starts.
What it costs in Mount Prospect
Blower cleaning in Mount Prospect generally ranges $150-$280, depending on whether the blower assembly requires full removal from a tight basement mechanical room.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the wheel, and reinstall with a photo record of the cleaned condition.
What HVAC Cleaning Costs in Mount Prospect
| Item | Typical range in Mount Prospect |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower cleaning | $150-$280 |
| Full HVAC system cleaning (coil, blower, air handler) | $350-$650 |
How do I know my HVAC system needs cleaning?
Visible dust at registers, reduced airflow, musty odors, or ice on coils indicate cleaning is needed. In Mount Prospect’s older homes, we also recommend inspection if the system has never been cleaned since a 1990s furnace upgrade. Call (224) 344-8881 for a free evaluation.
Can HVAC cleaning improve my energy bills?
Clean coils and blowers restore airflow efficiency, which can reduce runtime and energy use, especially in Mount Prospect homes where decades of debris force the system to work harder. We document before-and-after airflow readings when possible.
Air Quality & Sanitizing in Mount Prospect
Mount Prospect’s humid summers and aging duct systems create conditions where mold and bacteria colonize out of sight, particularly in the crawl-space trunk lines and disconnected branches hidden behind drywall from prior HVAC upgrades. Air quality and sanitizing addresses what cleaning alone cannot remove: active biological growth and persistent odors embedded in decades-old duct liner. Air Quality & Sanitizing details our full approach; the Mount Prospect specifics follow.
Mold Treatment
Signs you need it
Musty smell when the AC runs, visible mold at registers, or allergy symptoms that worsen when the system cycles on in humid summer months.
What it costs in Mount Prospect
Mold treatment in Mount Prospect typically ranges $250-$450 per affected zone, with whole-system treatment running $400-$700 depending on plenum accessibility in older ranch layouts.
How we do it
We apply EPA-registered antimicrobial through the duct system, treat the plenum with contact spray, and verify with post-treatment photo documentation showing the treated surfaces.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, persistent biological odors, or a household member with respiratory sensitivity to airborne contaminants.
What it costs in Mount Prospect
UV light installation in Mount Prospect generally runs $300-$550 for a properly sized unit with installation in the plenum or air handler.
How we do it
We size the UV-C unit to the system CFM, mount it at the coil or plenum location, wire to the blower circuit, and include the bulb replacement schedule in the written job record.
What Air Quality & Sanitizing Costs in Mount Prospect
| Item | Typical range in Mount Prospect |
|---|---|
| Mold treatment (per zone) | $250-$450 |
| Whole-system mold treatment | $400-$700 |
| UV light installation | $300-$550 |
Is mold in my ducts actually dangerous?
Active mold growth releases spores that can trigger respiratory irritation, particularly in children and allergy-sensitive individuals common in Mount Prospect’s family households. We treat with EPA-registered products and document the treated areas photographically.
How long does UV light treatment last?
UV-C bulbs degrade to about 70% output after 9,000-12,000 hours, roughly 12-18 months of typical Mount Prospect heating and cooling runtime. We note the replacement due date in your written job record.
