Why Cardinal Air Duct Marietta Is Marietta’s Preferred HVAC Cleaning Company
Marietta homeowners see the same pattern year after year: Georgia red clay dust settling into registers, pollen from spring dogwoods and pines packing onto coils, and humidity that turns dust into sludge inside ductwork. Our crews work these systems every week – from Victorians near the Square to 1980s split-levels off Roswell Road to newer flex-duct homes in west Cobb subdivisions. We know Marietta’s housing stock because we’re in it constantly, not because we read about it in a training manual.
Every job runs on the Relay Standard: you get a live trackable arrival window, before-and-after photo documentation of the work, and a digital invoice you can pay from your phone. Our HVAC Cleaning team operates under the 365-Day Done Right Promise – if something isn’t right within a full year, we come back and correct it at no charge. No fine print, no exceptions. Omar Haddad, who leads Cardinal Air Duct Marietta, built this process to eliminate the bait-and-switch reputation that plagues the duct cleaning trade. You know who’s coming, what they’ll do, and what it costs before a single register is touched.
Styles & brands we work with




Furnace Duct Cleaning in Marietta
Furnace Duct Cleaning in Marietta is one of the most-requested jobs we do, especially in the 1960s – 80s ranch and split-level homes that dominate neighborhoods like Chestnut Grove and Whitlock Heights. These homes often run original sheet metal supply trunks with decades of accumulated dust, pet dander, and fine clay powder that worked its way in through leaky return plenums. When you see dust on furniture within a day or two of cleaning, or registers puff a visible cloud when the blower kicks on, the furnace duct system is the source, not the housekeeping.
What the Job Involves
We connect a Nikro HEPA-rated negative pressure unit to the main trunk line, then agitate each branch run with Rotobrush tools sized to the duct dimensions. Negative-pressure extraction means loosened debris goes straight into the vacuum, never back into your living room. For furnace systems in Marietta, we also clean the blower wheel and housing – the fan blades on older units are often coated in a crust of red clay dust that reduces airflow and forces the system to run longer.
When Marietta Homeowners Need It
Homes near Powder Springs Road or along Barrett Parkway with original ductwork that hasn’t been opened in 15-plus years usually need this treatment. You’ll know by the register smudges, the musty smell on startup, or rising utility bills with no other explanation. Furnace duct cleaning in Marietta runs $380 – $560 for a typical single-system home under 2,500 square feet, depending on how many registers and returns the house has.
AC Coil Cleaning in Marietta
AC Coil Cleaning in Marietta gets ignored more than any other HVAC service, and it’s the one that costs homeowners the most in wasted energy. The evaporator coil sits above your furnace or inside the air handler, and in Marietta’s humid climate it stays wet for months at a time. Pollen, dust, and pet hair stick to that moisture and bake on, creating an insulating layer that chokes heat transfer. Your AC runs longer, your coil ices up, and the air coming out of your registers feels warm and heavy.
Evaporator Coil Cleaning
We clean the evaporator coil in place whenever possible, using coil-safe cleaners that break down the biofilm without corroding the aluminum fins. On older east Marietta homes with tight closet air handlers, we sometimes pull the coil for a full bath if the buildup is severe. Expect $180 – $280 for a standard evaporator coil cleaning as part of a full system job.
Condenser Coil Cleaning
The condenser coil out in the yard gets buried in grass clippings, cottonwood fuzz, and Cobb County pollen all summer. We wash the fins, straighten any bent ones, and clear the surrounding vegetation so airflow can move. A condenser coil cleaning in Marietta runs $120 – $200 and should happen every spring before the real heat arrives.
Trusted Brands We Service in Marietta
We service and clean systems from every major manufacturer you’ll find in Marietta homes – Carrier, Trane, Lennox, Rheem, Goodman, York, and American Standard. What matters more than the badge on the cabinet is the equipment we bring to the job. Our techs run Rotobrush brush systems for source removal, Nikro HEPA units for extraction, and Abatement Technologies containment when we’re dealing with fiberboard ductwork that sheds. We carry Guardsman coil treatments and filtration products on the trucks, so if your Marietta home needs a coil treatment or a better filter media, we can install it same visit.

AfterCommon HVAC Cleaning Problems We See in Marietta Homes
- Original fiberboard ductwork crumbling in east Marietta. Homes built in the 1960s and 70s near the Square often used fiberboard plenums and runs instead of sheet metal. After 50 years, the pressed-fiber material breaks down and sends gray particles through the registers – aggressive rotary brushing makes it worse, so we use gentler agitation and verify with camera inspection.
- Red clay dust caked on blower motors. Marietta’s soil is the fine, iron-rich clay that coats everything in dry weather. On ranch homes with undersized returns, that dust gets pulled into the cabinet and bakes onto the blower wheel, cutting airflow by 20-30% and re-contaminating clean ducts within weeks.
- Flex runs in converted attics loaded with pollen and mold. Many Marietta homes – especially 80s and 90s builds with bonus rooms – have flexible duct runs in attic spaces that hit 130 degrees in July. Humidity condenses inside, pollen sticks to it, and before long the register blows musty air. Cleaning only the main trunks misses these runs entirely.
- Crawlspace return leaks pulling in damp, dusty air. Older homes off Roswell Road and along Church Street frequently have return plenums running through damp crawlspaces. Loose joints pull in whatever’s under the house – moisture, mold spores, soil dust – and feed it straight into the system you breathe from.
Pricing for HVAC Cleaning in Marietta, GA
A full HVAC cleaning for a typical Marietta home runs $420 – $680, and that’s for the whole system: supply and return ducts, air handler, blower motor, and evaporator coil. Smaller jobs – just the ducts, or just the coils – start around $180. Larger homes over 3,000 square feet, or homes with two systems, run $700 – $950. The variables are register count, number of systems, and whether we’re dealing with rigid metal, fiberboard, or flex duct, since each requires different tools and time. You’ll get a written price before any work starts, and that number is final. Call (762) 216-4075 for a free estimate tailored to your home.

FAQs About HVAC Cleaning in Marietta
Every 2-3 years is realistic for a rural Marietta home with unpaved road traffic and wood heat, not the 3-5 year interval often quoted for suburban homes. Unpaved roads put fine dust in the air continuously, and wood stoves add ash and creosote particulate that settles in ducts. If you burn wood as a primary heat source, clean annually. Call (762) 216-4075 and we’ll assess your specific dust loading.
Yes, and it matters a lot. Thick-gauge 1960s metal ductwork can handle aggressive rotary brushing; thin flex duct from a 90s subdivision cannot – it tears. We size the agitation tools to the duct material and diameter, and we camera-inspect before ramping up pressure. The written quote reflects which method your home needs.
East Marietta builders in the 1960s and 70s used fiberboard plenums and branch runs as a cheaper alternative to sheet metal. It’s safe to clean when the material is intact, but brittle fiberboard crumbles under aggressive rotary brushes. We use gentler agitation and HEPA extraction, and we’ll tell you honestly if sections need replacement rather than cleaning.
Yes. On a 1970s split-level off Roswell Road near the Square, the coil wasn’t the only problem, but it was a big one. After we cleaned the evaporator coil and blower, airflow through the registers improved measurably, and the homeowner noticed dust stopped accumulating on surfaces as quickly. A coated coil forces the blower to work against higher static pressure, which both reduces airflow and pulls more dust through leaky returns.
Not necessarily. A workshop or barn with a simple ducted heat pump may need cleaning less often than your house, unless it shares the same dust exposure. But if you run a wood stove in an outbuilding or the system sits near an unpaved drive, yes, it’ll load up faster than a typical house system. We clean outbuilding systems as part of a full-property job, and the incremental cost runs $150 – $300 depending on the system size.
