We’ve worked Detroit’s housing stock for over 42 years. The brick bungalows along Gratiot, the two-family flats near Jefferson, the rehabbed colonials in West Village - we know the duct systems in these homes because we’ve cleaned and sanitized them. Detroit’s pre-WWII homes present air quality challenges that newer suburban construction simply doesn’t, and our technicians arrive prepared for what they’ll find behind those register covers.
Why Bellows Air Duct & Vent Co. Is Detroit’s Preferred Air Quality & Sanitizing Company
Detroit homeowners call us back because we show them the problem before we quote the fix. Every job starts with a camera inspection of your ductwork - a visual record you can see on screen, not a claim made over the phone. Our 90-Day Done Right Promise covers every sanitizing treatment we perform in Detroit: if mold returns, if odor persists, if something isn’t right, we return at no charge with no paperwork required.
Our office answers calls live around the clock. Not voicemail, not an app - a person who can dispatch a background-checked, uniformed technician to your Detroit home. Most air quality and sanitizing jobs in Detroit finish in one visit because our trucks carry Rotobrush mechanical cleaning systems, Abatement Technologies HEPA filtration, and professional-grade bacterial sanitizers. We don’t run back to a warehouse for parts while your Saturday disappears.
We disclose pricing before lifting a single tool. The number you hear on the phone matches the number on your invoice. No bait coupons, no scare tactics, no price changes when we walk through your door. That’s been our practice since 1984, and it’s why Detroit homeowners who’ve been burned by low-bid operators stick with Bellows.
Our Air Quality & Sanitizing Services in Detroit
Mold Treatment
Detroit’s heating season stretches from October through April, six months of forced-air circulation that spreads whatever lives in your ducts through every room. The Detroit River and Lake St. Clair push regional humidity higher than inland Michigan, and when that moisture meets the porous interior of 80-year-old galvanized trunk ducts - especially in homes that sat vacant with roof leaks or pipe bursts - mold colonizes fast.
We treat mold in Detroit homes with EPA-registered antimicrobial agents applied after mechanical agitation and HEPA vacuuming. A typical mold treatment in Detroit runs $340-$580 for a single-system home, $480-$780 for a two-family flat with separate duct runs. We document before-and-after conditions with camera inspection so you see the difference, not just smell it.
Bacteria Sanitizing
Standard duct cleaning removes loose debris. It does not sanitize. In Detroit’s historic housing stock, that’s a critical distinction. The large-diameter galvanized trunk ducts installed during octopus-furnace conversions have microscopic pitting and corrosion that harbor bacteria colonies standard vacuuming cannot reach.
Our bacterial sanitizing service applies a hospital-grade disinfectant fogged through the entire duct system, coating interior surfaces where mechanical tools can’t touch. For Detroit homes with post-foreclosure contamination - rodent droppings, bird nesting, water damage - this step isn’t optional. It’s the difference between clean ducts and ducts that stay clean. Bacteria sanitizing in Detroit typically adds $180-$320 to a cleaning service, or $280-$460 as a standalone treatment.
Odor Removal
Musty smells from Detroit vents rarely mean “just dust.” In the 48202 and 48205 ZIP codes, we regularly open registers in recently rehabbed homes and find compartments blocked with squirrel or pigeon nesting material - a direct legacy of properties sitting open and unsecured for 5-10 years during the foreclosure crisis. The odor isn’t dust. It’s biological contamination decomposing in your airflow.
We worked a job in the North End (48202) where the homeowner’s original 1920s octopus trunk duct was completely blocked with pigeon nesting material from years of vacancy. Using our Rotobrush system and Abatement Technologies HEPA filtration, we removed the debris and applied a bacterial sanitizer to eliminate the bird-dropping contamination before installing a UV light to prevent future mold growth. Odor removal in Detroit runs $320-$560 depending on contamination severity and duct accessibility.
UV Light Installation
UV-C light installed at your HVAC system’s air handler kills mold spores, bacteria, and viruses as air circulates. For Detroit’s old trunk duct systems, this matters enormously. Those oversized galvanized ducts create low-velocity zones where moisture collects and mold regrows even after thorough cleaning. A UV light provides continuous protection between professional services.
We specify and install UV lights from Honeywell and Aprilaire, brands serious HVAC contractors trust. Installation in Detroit typically costs $380-$620 including the unit, electrical connection, and placement optimization for your specific duct geometry. The bulb requires annual replacement; we stock replacements and can ship or deliver to your Detroit home.

Trusted Brands We Service in Detroit
Our Detroit trucks carry professional-grade equipment from Rotobrush, Abatement Technologies, and Nikro - the same brands commercial HVAC contractors specify for hospitals and schools. We don’t use consumer-grade shop vacs with duct-tape adapters. For UV light installations, we stock Honeywell and Aprilaire units with local warranty support, so if a Detroit winter knocks out your system and the UV module with it, we can replace components fast without waiting on California shipping. Parts availability matters when your furnace is running hard through another January subzero stretch.
Common Air Quality & Sanitizing Problems We See in Detroit Homes
- Homeowners skip sanitizing because vacuuming looks sufficient. The porous metal of old galvanized ducts harbors mold spores that regrow within weeks of mechanical cleaning alone. We’ve returned to Detroit homes six months after a “cleaning only” job to find black mold blooming through registers that looked spotless at completion.
- DIY sanitizing with bleach or ozone generators damages systems. Bleach corrodes galvanized steel and leaves chloramine residues that irritate lungs when heated. Ozone generators degrade rubber duct connectors and electrical insulation in older Detroit systems. Both approaches miss hidden contamination while creating new problems.
- Technicians fail to inspect for asbestos insulation fragments. Detroit’s pre-WWII homes often have deteriorated asbestos wrap around basement mechanicals and duct joints. Disturbing these with high-pressure cleaning releases airborne fibers. Our technicians inspect for this hazard before agitating any surface - it’s standard protocol on every Detroit job.
- Rehab contractors seal ducts without cleaning first. In Detroit’s active gut-rehab market, contractors sometimes install new HVAC equipment and seal old trunk ducts without removing foreclosure-era debris. The new system runs efficiently but circulates decades of contamination. We clean and sanitize before any sealing work.

FAQs - Air Quality & Sanitizing in Detroit
Even professionally rehabbed homes often retain original duct systems that sat dormant and exposed for years. Vacant properties accumulated rodent nesting, bird droppings, mold colonies from water intrusion, and construction debris from subsequent renovation work - all of which remains in trunk ducts unless specifically removed and sanitized. We recommend camera inspection of any Detroit home purchased as a foreclosure or rehab, regardless of how clean the visible spaces appear. Call (844) 685-6342 to schedule - estimates are free.
Yes, particularly in Detroit’s low-velocity galvanized ducts where moisture collects in dead zones a mechanical cleaning can’t reach. UV-C light at the air handler kills airborne spores before they settle and colonize, providing continuous protection between professional services. It’s not a substitute for initial remediation, but it prevents regrowth in systems prone to it. Most Detroit homeowners who install UV lights report reduced musty odor within two weeks. Call (844) 685-6342 for sizing and pricing specific to your system.
Musty odor from Detroit vents usually indicates active biological growth, not accumulated dust. Dust smells dry and stale; mustiness means mold, mildew, or decomposing organic material in your airflow. In Detroit’s 48202 and 48205 ZIP codes, we frequently trace musty odors to rodent or bird nesting material in trunk ducts - contamination from vacancy periods that standard cleaning won’t eliminate without targeted sanitizing. We find and fix the source, not just mask the smell. Call (844) 685-6342 for a camera inspection.
We do, though most Detroit octopus systems were retrofitted with blower motors decades ago. The original large-diameter trunk ducts remain, and they’re often the most contaminated components we encounter - 60 to 80 years of accumulation with no prior professional cleaning. We adapt our equipment to these oversized ducts and inspect carefully for asbestos insulation at joints and mechanical connections. If your Detroit home still has gravity-heat remnants, we’ll assess what’s safe to clean and what requires specialized handling. Call (844) 685-6342 to discuss your specific system.
Most Detroit two-family flats require four to six hours for complete cleaning, sanitizing, and camera-documented inspection. Two separate duct systems (one per unit) add complexity but not necessarily double the time, since our technicians work both simultaneously. Homes with severe foreclosure-era contamination - blocked trunk lines, extensive nesting material - may extend to a full day. We quote time along with price before starting, and we don’t leave until the job’s done right. Call (844) 685-6342 to book your appointment.
