We’ve been driving out to Lombard since 2012, back when the village was still filling in its post-war subdivisions and the Eisenhower Extension was new. Our technicians know the difference between a 1955 ranch on Main Street and a 1972 split-level near Madison Meadow Park - and more importantly, we know what those decades-old duct systems look like inside. Lombard’s housing stock isn’t generic, so your air quality solution shouldn’t be either.
Why Bellows Air Duct & Vent Co. of Chicago Is Lombard’s Preferred Air Quality & Sanitizing Company
Ray Dempsey built this company on the idea that a homeowner should never have to call twice for the same problem. That principle travels well - we’ve earned a strong local reputation in Lombard over four decades, with homeowners in the older neighborhoods near Westmore Elementary and the Yorktown area specifically recommending us to neighbors after mold treatments and UV installations.
Our response time to Lombard averages under 90 minutes from dispatch to driveway during regular hours, and our 24/7 live answering means you’re talking to a person at our office, not an app or voicemail tree, whenever you call. Every technician who enters your home is background-checked and uniformed, and every job starts with a camera inspection of your ductwork - before and after - so you see what we see.
What separates us in Lombard specifically is our familiarity with the village’s vintage housing. We’ve treated enough 1960s Cape Cods and split-levels to know that a standard duct cleaning without addressing the original humidifier is a temporary fix at best. Our Air Quality & Sanitizing team is trained to spot the moisture sources that generic services miss.
Our Air Quality & Sanitizing Services in Lombard
Mold Treatment
Lombard’s 1950s-1970s ranch and split-level homes nearly all had bypass or drum-type humidifiers added to the plenum. Under-maintained units create chronic moisture that turns decades of dust into mold deep in the ductwork, requiring mold-treatment protocols beyond standard cleaning. We recently treated a 1964 split-level on Elizabeth Street where a neglected drum humidifier had soaked the fiberglass duct liner in the supply trunk. After removing the liner, we applied Abatement Technologies sanitizer and installed an Aprilaire UV light at the coil to prevent regrowth - the homeowner avoided replacing the entire system. A typical mold treatment in Lombard runs $450-$850 depending on liner condition and plenum access.
Bacteria Sanitizing
Furnaces in Lombard run hard five months a year, and that continuous recirculation through original sheet-metal ducts creates ideal conditions for bacterial buildup on interior surfaces. Our sanitizing protocol uses professional-grade application equipment from Nikro to distribute treatment evenly through the full system, not just the reachable sections. We don’t apply product until we’ve camera-verified that the ducts are mechanically clean - otherwise you’re sanitizing over debris, which is a waste of your money. Most bacteria sanitizing jobs in Lombard fall between $280-$420.
Odor Removal
Musty or stale odors in Lombard’s older homes usually trace back to one of three sources: deteriorating fiberglass duct liner shedding organic material, mold colonies in low-clearance plenums, or dead-zone areas where humidifier moisture has pooled. We locate the source with borescope inspection before quoting any odor remediation - no guesswork, no masking agents. When the liner itself is the problem, removal and replacement is the only permanent solution. Odor-specific treatments in Lombard typically range $320-$580.
UV Light Installation
UV-C installation at the evaporator coil is one of the most effective preventive measures for Lombard’s climate, where summer humidity drives condensation and winter recirculation traps contaminants. We specify Aprilaire and Honeywell UV systems sized to your coil dimensions, not one-size-fits-all kits. The light kills mold and bacteria at the source before they colonize downstream ductwork. Installation in Lombard generally runs $380-$620 including the unit and electrical connection. We also offer standalone air purifier installations for homeowners who want whole-home treatment beyond the coil location.
Allergen Reduction
For allergy sufferers in Lombard’s 1960s-era Cape Cods and ranches, the combination of original fiberglass liner degradation and decades of dust loading creates a particulate problem that standard HVAC filters can’t address. Our allergen reduction protocol pairs source-removal duct cleaning with HEPA containment during the job, followed by sanitizer application and - where appropriate - UV installation to prevent recurrence. Most allergen-focused treatments in Lombard run $350-$650 depending on system size and liner condition.

Common Air Quality & Sanitizing Problems We See in Lombard Homes
- Mold in low-clearance plenums with no access panel. In Lombard’s older ranch neighborhoods, technicians regularly encounter basement plenums poured tight against the floor joists with no factory access panels - a construction norm of that DuPage County building era. Field-cut access points are required before any proper source-removal cleaning can begin, adding time and materials that should be quoted upfront, not discovered mid-job.
- Fiberglass duct liner acting as a contamination sponge. The original internal fiberglass liner in Lombard’s 50-to-60-year-old duct systems degrades over time, shedding particulate directly into the airstream while trapping moisture from under-maintained humidifiers. Applying sanitizer without removing compromised liner leaves the contamination source intact - we see this shortcut from discount operators regularly.
- Recurring mold from unaddressed bypass humidifiers. Failing to disable or replace the original bypass humidifier as an ongoing moisture source means the problem returns within months. We evaluate every humidifier during our initial inspection and recommend either proper maintenance, replacement with a steam unit, or safe disablement depending on your home’s needs.
- Skipped borescope inspections missing hidden colonies. Without camera inspection inside low-clearance plenums where no access panel exists, mold colonies formed by decades of humidifier moisture go undetected. We camera-inspect before and after every job - it’s how we verify the work and show you what was actually done.

FAQs - Air Quality & Sanitizing in Lombard
Yes - the humidifier itself must be evaluated, cleaned, and often disabled or replaced as part of proper mold remediation. We inspect the drum, pad, and water line for biofilm and mineral buildup that can recontaminate cleaned ducts within weeks. Most drum humidifiers in Lombard’s vintage homes are past their service life; we quote replacement options, including modern steam units, before any work begins. Call (877) 502-3903 for an exact assessment - estimates are free.
Deteriorated fiberglass liner must be removed - it cannot be effectively cleaned once it has absorbed moisture and begun shedding particulate. We camera-inspect first to assess liner condition, then quote removal and replacement with smooth metal or properly sealed duct board where appropriate. This is the most common hidden cost we find in Lombard’s split-levels, and we disclose it upfront, not after cutting access. Call (877) 502-3903 for a borescope inspection and honest quote.
Yes, we install UV-C systems at the coil, and they’re particularly effective in Lombard’s climate where summer humidity and winter recirculation create year-round mold pressure. The UV light prevents colony formation at the wettest point in your system, stopping downstream contamination before it starts. For homes with a history of mold or allergy issues, it’s the most cost-effective preventive measure we offer. Installation runs $380-$620. Call (877) 502-3903 to discuss whether your system configuration supports it.
We field-cut access points using proper sheet-metal protocols, then seal and insulate them to code after cleaning is complete. This is standard procedure for Lombard’s 1950s ranches, where plenums were often poured tight to joists with no thought to future maintenance. The extra labor and materials are included in our upfront quote - we don’t discover surprises halfway through your job. Call (877) 502-3903 and mention your Main Street location; we’ll factor access into your estimate.
Yes, but only as part of a complete protocol: source-removal cleaning to extract accumulated debris, liner removal if the original fiberglass is degrading, and sanitizer application to treated surfaces. Sanitizing alone without mechanical cleaning is ineffective. For Lombard’s Cape Cods with continuous furnace operation through long winters, we also recommend evaluating your filtration and considering UV installation at the coil for ongoing protection. Most allergen-focused treatments run $350-$650. Call (877) 502-3903 for a scope tailored to your symptoms and system condition.
