Call (877) 502-3903

Chicago’s climate pushes heating and cooling systems hard. Sub-zero polar vortex stretches and humid Lake Michigan summers keep furnaces and air handlers running at near-maximum capacity for eight or more months annually. That constant workload accelerates dust, debris, and microbial buildup inside components that most homeowners never see. Lake-effect moisture creeping through aging building envelopes on the north and northwest sides raises mold risk in ductwork, making professional cleaning more than a maintenance checkbox.

We show up when we say we will. Our technicians carry the equipment to handle Chicago’s toughest configurations, including the cramped crawl spaces and kinked flex ducts common in bungalow neighborhoods. One honest price, disclosed before we start. The number on the phone is the number on the invoice.

Why Bellows Air Duct & Vent Co. of Chicago Is Chicago’s Preferred HVAC Cleaning Company

Bellows has been a Chicago name since 2012. Ray Dempsey leads this operation with a simple standard: the job isn’t done until it’s done right, and we back that in writing for 90 days. No paperwork, no arguing. If something isn’t right, we return at no charge.

Our reputation here is built on never needing to be called back. Chicago homeowners who have lived in the same house for twenty or thirty years know the difference between a company that cleans visible surfaces and one that cleans the whole system. We camera-inspect before and after every job. You see what we see.

Calls are answered by a live person, 24 hours a day. Not a voicemail tree, not an app. When your furnace blower is laboring at midnight in January, someone picks up. Our background-checked, uniformed technicians arrive with professional-grade equipment from Rotobrush, Nikro, and Honeywell, the same brands serious HVAC contractors specify for their own jobs.

We understand Chicago’s housing layers: the bungalow belt, the two-flat courtyards, the postwar tracts on the far edges. Each era brought different ductwork challenges, and we’ve worked them all.

Our HVAC Cleaning Services in Chicago

Evaporator Coil Cleaning

The evaporator coil in your air handler is where cooling happens, and where Chicago’s humidity causes the most trouble. When dust and biological growth coat the fins, airflow drops, ice forms, and your compressor strains. In Rogers Park and Edgewater, where Lake-effect moisture is constant, we see coils that need more than a rinse. We apply a Guardsman coil treatment after mechanical cleaning to slow future buildup. A typical evaporator coil cleaning in Chicago runs $180-$340.

Blower Cleaning

The blower motor and wheel move every cubic foot of conditioned air through your house. In Chicago’s bungalow neighborhoods, where 1970s retrofits often placed air handlers in cramped basement corners, blowers accumulate debris that standard vacuums can’t reach. We remove the assembly when necessary, clean the housing and wheel blades, and reassemble with proper balance. Most blower cleanings in Chicago fall between $150-$280.

Condenser Cleaning

Your outdoor condenser coil faces Chicago’s full weather range: pollen, cottonwood seed, road grit, and winter salt spray. A dirty condenser can’t reject heat efficiently, so your electric bill climbs while cooling capacity falls. We fin-straighten, chemically clean, and rinse thoroughly. Condenser cleaning in Chicago typically costs $120-$220 as a standalone service, or less when bundled with indoor work.

Air Handler Cleaning

The air handler is the central station: blower, coil, filter rack, and often the backup heat strips. In Chicago two-flats and three-flats, these units sometimes sit in closets with minimal access, or in damp basements where rust and mold take hold. We clean the full cabinet, treat for microbial growth where indicated, and document condition with camera footage. Air handler cleaning in Chicago ranges from $220-$420 depending on size and accessibility.

Heat Exchanger Cleaning

The heat exchanger is where combustion gases transfer warmth to your air stream. In Chicago’s older housing stock, cracked or heavily sooted exchangers pose real safety hazards. We inspect with cameras and, where accessible, clean to improve efficiency and reveal hidden damage. This service runs $200-$380 in the Chicago market. If we find cracks, we stop work and advise replacement, no exceptions.

Coil Treatment

After mechanical cleaning, we apply EPA-registered treatments to evaporator and condenser coils. This isn’t a substitute for cleaning, but it extends results, especially in Chicago’s humid summer months. Treatment is typically $45-$85 when added to a cleaning service.

Trusted Brands We Service in Chicago

We clean and service equipment from every major manufacturer, and we stock common parts for faster turnaround on Chicago jobs. Our cleaning equipment comes from Rotobrush, Nikro, and Honeywell, brands that build machines for daily commercial use, not occasional residential dabbling. We also specify Aprilaire media filters and humidifier components where upgrades make sense. For Chicago homeowners with aging systems, this means we can often complete a full cleaning and minor repair in one visit, without waiting for parts to ship.

Common HVAC Cleaning Problems We See in Chicago Homes

• Bungalow retrofit ductwork. Chicago’s roughly 80,000 classic bungalows, concentrated on the northwest and southwest sides, were built for steam heat between 1910 and 1940. Most were later retrofitted with forced-air systems shoehorned into spaces never designed for ductwork. That retrofit ductwork is now 40-60 years old, often routed through cramped crawl spaces and oddly notched floor joists, accumulating decades of debris in configurations that standard cleaning equipment struggles to navigate.
• Asbestos-wrapped insulation in pre-WWII housing. Chicago’s enormous stock of two-flats, three-flats, and courtyard greystones frequently contains asbestos-wrapped duct insulation from mid-century forced-air conversions. Our technicians assess for ACM before aggressive cleaning, and we coordinate with certified abatement contractors when disturbance is unavoidable. This is not a corner to cut.
• Lake-effect moisture and mold risk. Sustained humidity infiltration through aging building envelopes on the north and northwest sides creates conditions for mold colonization inside ductwork. We treat active growth with appropriate products and advise on envelope repairs when the source is obvious.
• Postwar galvanized oxidation. Tract construction on the far north and south sides added another wave of aging ductwork, now 50-70 years old, with galvanized sheet metal that has accumulated heavy oxidation scale. This scale breaks loose and circulates, and it requires more aggressive mechanical removal than newer systems.
