Why Bellows Air Duct & Vent Co. of Chicago Is Portage Park’s Preferred Air Quality & Sanitizing Company

We’ve been serving Chicago homeowners since 2012, and Portage Park has been part of our route for decades. Ray Dempsey built this company on the idea that a square deal means saying what you’ll do, doing it, and fixing it if it’s not right - no paperwork, no arguing. That approach resonates in Portage Park, where homeowners have lived in the same bungalow for twenty, thirty, sometimes forty years and have seen enough contractors come and go.

Our technicians know the difference between a 1920s gravity conversion duct and a 1980s retrofit before they even open the basement door. We’ve treated mold in basements near Portage Park’s namesake park, removed odors from two-flats along Lawrence Avenue, and installed UV lights in bungalows off Montrose where the original tin trunk lines still run the length of the house. Most Portage Park calls reach us within our standard Chicago response window, and because we’re based here in the city, we’re not driving in from the suburbs with a GPS and a coupon book.

Every job gets a camera inspection before and after. You see what we see. And our pricing is disclosed upfront - the number on the phone is the number on the invoice. No bait, no switch, no “we found something else” once we’re in your basement.

Our Air Quality & Sanitizing Services in Portage Park

Mold Treatment

Portage Park’s uninsulated sheet metal trunk ducts are a mold problem waiting to happen. Chicago furnaces push heated air through these lines from October to April, then summer humidity hits and the cold metal sweats condensation inside your basement. That moisture, combined with decades of accumulated dust, creates colonies that standard cleaning won’t touch. Our mold treatment in Portage Park starts with a camera inspection to locate the growth, followed by HEPA-contained mechanical removal and application of an EPA-registered botanical sanitizer. A typical mold treatment in a Portage Park bungalow runs $450-$780 depending on linear footage of affected duct and whether we need to address the trunk line or branch ducts as well.

We recently sanitized a bungalow on Montrose Avenue where the original 1930s trunk duct was wrapped in asbestos-laced insulation. Our tech used a HEPA-vac with HEPA-grade filtration and applied a botanical sanitizer approved for old metal. The homeowner had been noticing winter condensation dripping from the uninsulated tin, and after our treatment, they reported immediate relief from musty odors.

Bacteria Sanitizing

The same oversized duct cross-sections that made gravity furnaces work also make bacteria sanitizing more complex in Portage Park. A typical modern flex duct is 6-8 inches round. Your original trunk line might be 20 by 8 inches rectangular, with hand-seamed corners and decades of renovation dust settled in places a standard brush can’t reach. Our bacteria sanitizing service uses professional-grade foggers and contact applicators from Rotobrush and Nikro equipment lines, sized for the job. We treat the full surface area, not just what the brush touches. Most bacteria sanitizing jobs in Portage Park run $350-$620 for a full system, and we complete them in a single visit.

Odor Removal

That basement smell in Portage Park isn’t “just old house.” It’s usually a combination of mold metabolites, dust mite debris, and organic material breaking down in your ducts - all amplified by the humidity cycling that Chicago’s climate forces through uninsulated metal. Our odor removal process targets the source, not the symptom. We camera-inspect to find where the odor originates, mechanically remove the contamination, and apply oxidizing and botanical treatments that neutralize the compounds causing the smell. For Portage Park bungalows with original ductwork, odor removal typically costs $400-$720 and includes our follow-up check at 30 days to confirm the problem is resolved.

UV Light Installation

UV lights work in old sheet metal ducts, but installation requires planning. The large cross-section of a Portage Park trunk line means a single UV lamp won’t cover the full volume the way it would in a modern 6-inch round duct. We calculate lamp placement and intensity based on your actual duct dimensions, not a standard formula. Most Portage Park UV installations run $680-$1,200 for a properly sized system with in-duct mounting and electrical connection. We use Honeywell and Aprilaire UV components - the same brands serious HVAC contractors specify - and we warranty the installation for 90 days under our Done Right Promise.

Trusted Brands We Service in Portage Park

We don’t show up with hardware-store equipment and hope for the best. Our trucks carry Rotobrush and Nikro agitation and vacuum systems built for residential ductwork, and we stock Honeywell and Aprilaire air purifiers and UV components for same-day installation when possible. For Portage Park homeowners, that means faster turnaround and fewer return visits. If your system needs a specific component, we source it from authorized distributors - no generic substitutes, no “this will work just as well.” The brands we specify are the same ones Ray Dempsey has trusted since he founded Bellows in 1984, because they’ve proven they hold up in Chicago’s climate and in Chicago’s houses.

Common Air Quality & Sanitizing Problems We See in Portage Park Homes

• Asbestos-containing tape or insulation on pre-1950s ductwork gets disturbed during a routine clean, requiring emergency abatement that doubles costs and delays sanitizing. We identify this visually before any mechanical work begins. If we suspect asbestos, we stop and recommend certified testing. It’s a step discount operators skip, and it protects your home and your health.
• Uninsulated, oversized trunk ducts in basements sweat in summer humidity, promoting mold colonies that standard sanitizing foggers miss because the moisture persists. We address the moisture source as part of our treatment plan, not as an afterthought. Sometimes that means recommending insulation. Sometimes it means more aggressive mold protocol.
• Original gravity-furnace conversion ducts have large cross-sections; typical drum-brush equipment cannot reach all surfaces, leaving pockets of renovation dust and mold spores unaffected. We size our equipment to your ducts, not the other way around. Our Rotobrush systems include extensions and attachments for rectangular trunk lines that standard kits don’t include.
• Seventy to ninety years of debris accumulation in hand-fabricated seams and corners, including lead paint dust, plaster residue, and animal dander from previous owners. This isn’t a surface clean. It’s archaeological. We treat it with the thoroughness it requires, and we show you the before-and-after on camera.
