Bellows Air Duct & Vent Co. has served the Marietta area for over 42 years, and our crews know the specific challenges of East Cobb’s aging housing stock. If you’re dealing with musty odors, allergy flare-ups, or visible mold around your vents, call us at (844) 685-6342.

Marietta sits in one of the highest seasonal pollen-load corridors in the country. Dense loblolly pine and oak canopy throughout neighborhoods off Johnson Ferry Road and Roswell Road generate extreme spring pollen events that infiltrate return-air grilles and leaky duct connections. Combine that with 90°F+ summers and unconditioned attic duct runs, and you’ve got recurring condensation inside flex ducts - a problem that keeps coming back unless it’s treated at the source. That’s why our Air Quality & Sanitizing team doesn’t just clean; we assess, treat, and protect.
Why Bellows Air Duct & Vent Co. Is Marietta’s Preferred Air Quality & Sanitizing Company
We’ve been driving to Marietta since 1984, long before the East Cobb corridor filled out with the subdivisions we now service weekly. Our reputation here is built on one thing: we don’t need to be called back. The 90-Day Done Right Promise covers every job - if it’s not right, we return at no charge with no paperwork required.
Our phone rings with Marietta homeowners who found us through neighbors in ZIPs 30068, 30069, 30090, and 30006. They mention the same thing: the last company gave a low phone quote, then doubled it at the door. That doesn’t happen with Bellows. The number you hear on the phone is the number on the invoice. Period.
Response time to Marietta is typically same-day or next-morning, depending on call volume. Our technicians are background-checked, uniformed, and equipped with Rotobrush agitation systems and Abatement Technologies antimicrobial treatments. They know the difference between a 1987 split-level off Roswell Road and a 2005 townhome near Marietta Square, and they adjust their approach accordingly.
Calls are answered by a live person, 24 hours a day. Not a voicemail. Not an app. A real person who can dispatch a crew to your Marietta home.
Our Air Quality & Sanitizing Services in Marietta
Mold Treatment
Mold in Marietta homes isn’t a one-time problem - it’s seasonal and structural. The combination of Georgia’s high dew points and unconditioned attic duct runs creates condensation inside flex ducts every summer. We find active mold at attic connections in East Cobb subdivisions built during the 1980s-90s boom, particularly where original builder-grade flex duct has degraded past its design lifespan. Our mold treatment starts with a camera inspection to locate the growth, followed by mechanical removal with Rotobrush agitation, then application of an EPA-registered antimicrobial sanitizer from Abatement Technologies. In severe cases, we recommend UV light installation to prevent recurrence. A typical mold treatment in Marietta runs $340-$580 for localized issues, or $520-$850 for whole-home systems with multiple contamination points.
Bacteria Sanitizing
Bacteria sanitizing addresses the microbial load that standard duct cleaning leaves behind. In Marietta’s older ranch homes in the 30060-30064 ZIPs, partially accessible crawl-space ductwork draws moisture from red Georgia clay subsoil, creating ideal conditions for bacterial growth. We apply professional-grade sanitizers that are safe for occupied homes but effective against the biofilm that builds on duct interiors. This service is often paired with mold treatment for homes that have both visible and hidden contamination. Bacteria sanitizing in Marietta typically costs $180-$320 as an add-on to duct cleaning, or $280-$450 as a standalone service.
Odor Removal
Musty odors in Marietta homes usually trace back to one of two sources: degraded flex duct liners shedding debris into the airstream, or microbial growth at condensation points in unconditioned attics. We recently treated a 1992 townhome on Church Street in the 30060 ZIP where the homeowner complained of musty odors and allergy flare-ups. Our crew found a degraded flex liner with visible mold at the attic duct connections. We performed a full Rotobrush cleaning, then applied an Abatement Technologies EPA-registered antimicrobial sanitizer to kill the hidden microbial growth, resolving the odor and improving the home’s air quality within one visit. Odor removal services in Marietta range from $220-$420 depending on system size and contamination severity.
UV Light Installation
UV lights are the most effective long-term defense against mold recurrence in Marietta’s climate. Installed at the evaporator coil or in the return plenum, a UV-C lamp kills mold spores, bacteria, and viruses before they circulate through your home. For Marietta homeowners who’ve already dealt with mold in their attic duct runs, UV installation prevents the next cooling season from bringing the same problem back. We specify professional-grade UV systems from brands serious HVAC contractors trust. UV light installation in Marietta runs $380-$650 for a single-lamp system, or $680-$950 for whole-home multi-lamp configurations with annual bulb replacement plans.
Air Purifier Installation & Allergen Reduction
Whole-home air purifiers address the pollen infiltration that makes Marietta’s spring months miserable for allergy sufferers. We install Aprilaire and Honeywell media air cleaners that capture particles down to 0.3 microns, including the pine and oak pollen that blows through leaky duct connections. For homes with significant allergen loads, we may recommend pairing a media cleaner with UV treatment for comprehensive protection. Air purifier installation in Marietta typically costs $450-$780 for a standard whole-home unit, with annual filter replacement running $85-$140.

Trusted Brands We Service in Marietta
We don’t show up with equipment from a hardware store clearance rack. Our crews carry Rotobrush agitation systems for mechanical duct cleaning, Abatement Technologies EPA-registered antimicrobial treatments for sanitizing, and Aprilaire whole-home air purification systems for installation. These are the same brands specified by serious HVAC contractors in the Marietta market. We stock common replacement parts and UV bulbs locally, so if your system needs a component we don’t have on the truck, we can typically source it within 24 hours. No waiting two weeks for a mail-order part while your mold problem spreads.
Common Air Quality & Sanitizing Problems We See in Marietta Homes
- Mold recurrence in unconditioned attic ducts after heavy spring pollen seasons. The pollen load itself isn’t the mold source, but it clogs filters and reduces airflow, causing coils to run colder and produce more condensation. Without a UV light or antimicrobial treatment applied post-cleaning, the mold returns every cooling season.
- Oversized flex runs from 1980s-90s construction collecting settled particulates. Original HVAC systems in East Cobb were sized for lower-efficiency equipment, leaving duct runs larger than necessary. Low-power vacuums can’t agitate debris from these oversized ducts; our Rotobrush systems are specifically designed for this failure mode.
- Condensation damage inside flex ducts during summer dew point spikes. When attic temperatures exceed 140°F and dew points climb into the 70s, moisture forms on the inner liner of degraded flex duct. Biological contamination follows. A simple cleaning won’t fix this - the damaged duct needs replacement, and the system needs sanitizing.
- Degraded inner liners flaking debris directly into the airstream. In East Cobb subdivisions like those off Johnson Ferry Road, the 30-35-year-old flex duct inner liners are known to delaminate and flake due to extreme attic heat cycling. Homeowners report “dust that never settles” - it’s not dust, it’s shredded plastic liner. This requires combined cleaning and assessment, often converting to a full duct-replacement recommendation.

FAQs - Air Quality & Sanitizing in Marietta
The original builder-grade flex ductwork in these homes is now 30-35 years old, past its design lifespan, and the plastic inner liners have degraded from extreme attic heat cycling common in Georgia. Standard duct cleaning removes loose debris but doesn’t address the flaking liner material or the mold growing at condensation points inside degraded ducts. These homes need combined cleaning and assessment, often with antimicrobial treatment or UV installation to prevent recurrence. Call (844) 685-6342 for a free estimate - we’ll camera-inspect your system and show you exactly what you’re dealing with.
UV lights kill mold, bacteria, and viruses but do not filter pollen. For Marietta’s extreme spring pollen events, we recommend pairing UV treatment with a whole-home media air cleaner like Aprilaire, which captures pollen particles before they circulate. The UV light then prevents the mold that grows when pollen-clogged filters reduce airflow and cause condensation. A combined system runs $680-$1,200 installed. Call (844) 685-6342 and we’ll size the right configuration for your home.
We bring compact Rotobrush equipment and flexible hose extensions specifically for tight clearances. For homes with scuttle holes too small for a technician, we can often access ducts from the crawl space or through strategically removed return grilles. We’ll show you the access plan during our upfront assessment - no surprises, no sheetrock damage you didn’t approve. Call (844) 685-6342 to schedule a look.
Yes. Our service vans fit standard parking spaces, and we carry equipment designed for urban and townhome layouts where alley access is shared and restricted. For the townhome on Church Street we recently treated, we staged from the resident parking area and ran hoses through the ground-floor utility closet, never blocking the alley. We’ll coordinate with your HOA or property manager if needed. Call (844) 685-6342 to discuss your specific access situation.
We install Aprilaire whole-home media air cleaners, Honeywell electronic air cleaners, and professional-grade UV-C systems from Abatement Technologies. These are the brands HVAC contractors specify for the Marietta market, with local parts availability and established performance in Georgia’s climate. We do not install discount units with no local support. Call (844) 685-6342 for brand-specific recommendations based on your system and concerns.
