Fast, Reliable HVAC Cleaning Across Marietta
Professional HVAC cleaning in Marietta typically runs $280-$650 for a complete system cleaning, and most jobs are finished in a single visit. Our HVAC Cleaning crew knows the crawl-space ductwork common to Marietta’s older ranch homes, and we carry the equipment to handle corroded galvanized trunk lines and disconnected flex runs that less experienced crews miss. We’ve been driving to Marietta from our Atlanta office for over 42 years - long enough to remember when the stretch of Canton Road past the Square was still two lanes. Call (855) 305-5564 and a live person will answer, day or night.
Why Bellows Air Duct & Vent Co. of Atlanta Is Marietta’s Preferred HVAC Cleaning Company
Marietta homeowners don’t call us because of a coupon. They call because their neighbor on Manning Road did, or their cousin in the Whitlock Avenue area, and word in Cobb County travels straight. We’ve built that reputation one house at a time - brick ranches near the Square, split-levels off Roswell Road, newer construction west of 75 - and we answer for every job with our 90-Day Done Right Promise in writing.
Our technicians are background-checked and uniformed, and they show up when we say they will. That’s not a slogan. It’s how we’ve operated since 1984. Marietta’s humid Piedmont climate and heavy pollen loads mean HVAC systems here work harder and get dirtier faster than in drier parts of the metro. We know which ZIP codes - 30060, 30062, 30008, 30061 - have the crawl-space configurations that trap moisture, and we know how to fix them so the cleaning actually lasts.
Calls come to a live person, 24 hours a day. Not an app. Not a callback queue. A real voice at our office who can dispatch a crew to Marietta today.
Our HVAC Cleaning Services in Marietta
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler, and in Marietta it takes a beating. Spring pollen from the loblolly pines and white oaks surrounding the city coats the coil in a sticky yellow film. Summer humidity above 70% lets that organic matter foster mold. We pull the coil, clean it with professional-grade foaming agents from Nikro, and inspect the drain pan for algae buildup common to homes near the Chattahoochee River basin. A clean coil drops your energy bill and stops the musty smell that blows through vents in older 30060 ranches.
Air Handler Cleaning
Your air handler is the lungs of the system. In Marietta’s post-WWII ranch homes - the ones Lockheed workers bought by the thousands - air handlers often sit in crawl spaces where fiberglass liner degrades and pest debris accumulates. We disassemble the housing, vacuum with Rotobrush negative-air equipment, and camera-document before and after. One honest price, shown before we start. No bait-and-switch.
Blower Cleaning
The blower wheel moves every cubic foot of air in your home. When it’s caked with Georgia red-clay dust and pollen, it strains the motor and pushes less air. We remove the blower assembly, clean each blade, balance the wheel, and check the motor bearings. Most Marietta homes need this every 3-5 years given the local pollen load.
Condenser Cleaning
Your outdoor condenser sits in Marietta’s heat and humidity, often under oak trees that drop leaves and acorns into the fins. We wash the coils, straighten bent fins, and clear the concrete pad of debris that blocks airflow. A clean condenser runs cooler and lasts longer - critical when August temperatures in Cobb County hit the mid-90s.
Coil Treatment
After cleaning, we apply a protective treatment to evaporator and condenser coils that resists mold regrowth in Marietta’s humid conditions. This isn’t a upsell. It’s standard on our full-system cleans because untreated coils in this climate start recontaminating within weeks. The treatment carries a 90-day efficacy window, backed by our Done Right Promise.
Heat Exchanger Cleaning
Gas furnaces in Marietta’s older homes - many original to the 1960s-80s construction boom - develop carbon deposits and rust in the heat exchanger. We inspect with cameras, clean with compressed air and soft brushes, and check for cracks that could leak carbon monoxide. Safety first. Always.

Trusted Brands We Service in Marietta
We clean and maintain systems built around Honeywell controls, Aprilaire media filters, and equipment from Rotobrush and Nikro - the same brands serious HVAC contractors specify for their own homes. Our trucks stock common replacement parts for Marietta’s most prevalent system types, so we’re not driving back to Atlanta mid-job. That matters when you’re working on a 1970s ranch with original galvanized ductwork that needs same-day attention. We source Aprilaire filter media locally for Marietta customers who want upgraded filtration against the spring pollen onslaught.
Common HVAC Cleaning Problems We See in Marietta Homes
- Crawl-space moisture corrosion. In neighborhoods east of the Marietta Square, original galvanized trunk lines from the 1960s-80s corrode at seams where condensation collects. We find pinhole leaks blowing conditioned air into crawl spaces, and we seal them with mastic - not duct tape - so the fix lasts.
- Disconnected flex-duct runs. Brittle flexible ductwork in older Marietta ranches separates from collars and blows debris-laden air directly into crawl spaces. Homeowners feel “weak airflow” upstairs; the real problem is air going nowhere useful. We reattach with proper straps and sealant.
- Heavy pollen and red-clay dust loading. Marietta’s spring pollen counts rank among the highest in metro Atlanta, and the Georgia Piedmont’s red clay generates fine dust that embeds in fiberglass duct liner. Generic vacuum power won’t extract it. We use commercial negative-air machines with sufficient CFM to pull that debris free.
- Mold in unconditioned crawl-space ducts. Summer humidity above 70% meets organic pollen loads inside dark ductwork. The result is black mold growth that blows spores through every vent. We treat with EPA-registered sanitizer and apply preventive coating.

FAQs - HVAC Cleaning in Marietta
Crawl-space ducts in Marietta’s 1960s-1980s ranch homes sit in unconditioned, humid environments where mold, pest debris, and liner deterioration accelerate. Attic-mounted systems in newer Kennesaw construction stay drier and cleaner. In Marietta’s persistently humid Piedmont climate, professional duct cleaning becomes recurring maintenance, not an optional upgrade. Call (855) 305-5564 for a free inspection - we’ll show you exactly what your crawl-space ducts look like on camera.
Yes. Cleaning the evaporator coil removes the sticky pollen film that acts as a breeding ground for mold and bacteria. In Marietta, where loblolly pine and white oak pollen coats return-air grilles within days each spring, a clean coil plus upgraded filtration reduces indoor particulate significantly. We recommend pairing coil cleaning with an Aprilaire media filter for homes near the Square or along Roswell Road. Call for a free estimate.
Yes. We reattach disconnected flex-duct runs with proper metal straps and mastic sealant, then pressure-test the repair. This is standard practice during our HVAC cleaning service in Marietta, where brittle original flex duct in 30060 and 30062 neighborhoods separates at collars after decades of vibration. We include minor reattachment in our complete system clean; extensive replacement gets quoted upfront before work proceeds. Call (855) 305-5564 to schedule.
It can be. Late-1990s to 2000s construction in 30066 and west Marietta (30064) produced homes with attic-mounted systems, but Georgia red-clay construction dust and heavy seasonal pollen still load ductwork during the first decade of occupancy. We frequently find thick dust layers in return trunks of homes built during the 2000s building boom. A thorough HVAC cleaning removes that legacy loading and lets your filtration work properly. Free estimates available.
We inspect with cameras, clean the interior debris, seal pinhole leaks and seam gaps with mastic, and document the condition. If corrosion has penetrated the metal, we quote replacement - but many Marietta galvanized trunks from the 1960s-80s remain structurally sound once properly sealed. We serviced a 1972 brick ranch on Old Canton Road, Marietta 30060. The evaporator coil was caked with red-clay dust and pollen; the galvanized supply trunk had pinholed at the seams from 50 years of crawl-space moisture. We cleaned the coil, sealed the trunk with mastic, and reattached three disconnected flex runs that were blowing debris into the crawl space - everything restored in one trip. Call for an honest assessment of your system.
