Air Duct Cleaning in Marietta - One Flat Price, Before-and-After Photos

Air Duct Cleaning in Marietta, GA

Whole-system HVAC cleaning in Marietta typically runs $450-$850 for a single residential system, with most jobs completed in one visit and every duct run photographed before and after. The combination of Cobb County’s 1975-1995 housing stock, extreme pollen loads, and attic temperatures that degrade flex duct makes this a distinct market from drier or newer-built metros.

Why Marietta Homes Are Different

Marietta sits inside one of the highest pollen-count metros in the United States - the Atlanta area regularly records tree pollen levels above 10,000 particles per cubic meter, well into the “extremely high” range - and Cobb County’s dense oak and pine canopy amplifies this locally. Homes here pull extraordinary volumes of biological particulate through return vents each spring, making duct systems that go uncleaned for years a significant indoor air-quality problem in a way that simply isn’t as acute in drier or less-forested metros.

Cobb County experienced its core suburban build-out from roughly 1975 through the mid-1990s, leaving Marietta with a large inventory of ranch and two-story homes fitted with flexible fiberglass duct systems - now 30-50 years old and sitting in unconditioned attics that routinely hit 130-140°F in summer. That heat accelerates inner-liner degradation, causes flex duct to sag and collect debris at low points, and creates the warm, humid conditions that encourage mold colonization inside the insulation wrap. In East Cobb’s established subdivisions - neighborhoods zoned for Murdock, Lassiter, and Pope schools - many original homeowners have lived in the same house since the 1980s and have never had the duct system professionally cleaned. Technicians in this area frequently find 30-year accumulations of Georgia red-clay dust, insulation fibers from degraded flex duct, and compacted pollen mats packed against return-air grilles in the hallway ceiling.

Marietta’s humid subtropical climate means HVAC systems run cooling for 6+ months of the year, drawing air continuously through ductwork. The combination of warm indoor humidity and attic heat differentials creates condensation risk at duct joints, which feeds mold growth that then circulates through the living space with each blower cycle. This is not a theoretical concern - it’s what we document with cameras on a weekly basis.

Our Main Marietta Services

Most calls from Marietta homeowners fall into three categories. Here’s what each involves locally.

Air Duct Cleaning in Marietta

We clean the full duct network - supply and return runs, trunk lines, and plenum - using negative-pressure extraction (a vacuum system that pulls debris out while containing it, rather than blowing it through the house). In Marietta, we typically find heavy pollen accumulation in returns facing wooded lots, plus degraded flex-duct liner that has begun to shed fiberglass particles into the airstream. Every run is photographed before and after, and the photo record is delivered with the written invoice. Air Duct Cleaning in Marietta

Dryer Vent Cleaning in Marietta

Dryer vent blockages are common in Marietta’s older subdivisions where original vent routing used 4-inch flexible transition duct behind the dryer and rigid pipe through long attic runs. Lint accumulates at elbows and low points, and the humid climate causes partial clogs to compact into dense mats. We clean the full run from lint trap to exterior termination, verify airflow with a meter, and note any code deficiencies in the written report. Dryer Vent Cleaning in Marietta

Duct Repair & Sealing in Marietta

Many Marietta homes still operate with original flex duct that has sagged, torn at seams, or separated from collars entirely. We replace damaged sections with properly supported flex or switch to rigid metal where accessibility allows, then seal all joints with mastic (a brush-applied sealant that outlasts tape in attic heat). The goal is restored airflow balance and reduced energy loss through leakage. Duct Repair & Sealing in Marietta

HVAC Cleaning in Marietta

HVAC cleaning in Marietta addresses the components that move and condition air but are not part of the duct network itself - the evaporator coil, blower assembly, condenser, and air handler. These components are exposed to the same pollen volume and humidity that saturate local ductwork, and because Marietta systems run cooling six or more months per year, biological growth on wet coils is a routine finding rather than an occasional one. HVAC Cleaning here means addressing the full air path, not just the passages between rooms.

Evaporator Coil Cleaning

Signs you need it

Ice buildup on the coil, reduced airflow from registers, or a musty odor when the blower first starts are common indicators in Marietta’s high-humidity environment.

What it costs in Marietta

Evaporator coil cleaning typically ranges from $280-$450 as a standalone service, or $180-$320 when bundled with a full system cleaning.

How we do it

We access the coil through the plenum (the main distribution box above the furnace), apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water, and photograph the before and after condition through the access panel.

Blower Cleaning

Signs you need it

Vibration or noise from the air handler, uneven airflow between rooms, or dust streaking from supply registers often point to an imbalanced or debris-loaded blower wheel.

What it costs in Marietta

Blower assembly cleaning generally runs $220-$380 depending on accessibility and whether the housing requires full removal.

How we do it

We remove the blower housing, clean the wheel blades and motor housing with compressed air and solvent, balance the assembly on reinstallation, and record amp draw before and after to verify improved efficiency.

What HVAC Cleaning Costs in Marietta

How do I know my HVAC components are actually dirty?

We photograph every component before touching it - the coil, blower wheel, and plenum interior - and deliver those images with the written invoice. If the coil shows no biological growth or debris buildup, we’ll tell you before quoting any work. Haven Standard Clause 1: written price before work starts, always.

Can HVAC cleaning fix my high summer electric bills?

Dirty coils and blower wheels force the system to run longer to reach setpoint; cleaning can restore efficiency to manufacturer specifications. In Marietta’s six-month cooling season, that runtime reduction is measurable, though we won’t promise a specific dollar savings without inspecting your system first.

Air Quality & Sanitizing in Marietta

Air quality and sanitizing in Marietta targets the biological load that accumulates in duct systems exposed to extreme pollen, attic heat, and year-round humidity. The same flex-duct degradation and condensation conditions that make HVAC cleaning necessary here also create environments where mold and bacteria colonize inside duct walls, then distribute through living spaces with each blower cycle. Air Quality & Sanitizing is not a fragrance treatment - it’s documented remediation of verified contamination.

Mold Treatment

Signs you need it

Visible mold around register edges, a persistent earthy odor when the system runs, or recent water intrusion in the attic or crawl space are clear indicators in Marietta’s climate.

What it costs in Marietta

Whole-system mold treatment typically ranges from $680-$1,200 depending on contamination extent and whether damaged duct sections require replacement.

How we do it

We apply an EPA-registered antimicrobial through the full duct network using controlled fogging equipment, treat the evaporator coil and plenum, and collect post-treatment samples to verify reduction - with all documentation included in the job record.

UV Light Installation

Signs you need it

Recurring mold growth despite previous cleaning, chronic allergy symptoms that worsen when the system runs, or a home with persistent moisture issues in the HVAC cabinet suggest UV-C suppression is warranted.

What it costs in Marietta

UV-C light installation in the plenum or air handler typically runs $380-$620 including the lamp, ballast, and electrical connection.

How we do it

We mount a UV-C lamp with a sight glass in the supply plenum, wire it to the blower circuit so it operates only when air is moving, and specify replacement intervals - usually 12-18 months for standard lamps, 24-36 months for high-output units.

What Air Quality & Sanitizing Costs in Marietta

Is the chemical treatment safe to breathe afterward?

We use EPA-registered products with specified re-entry times, typically 2-4 hours with the system running to flush residual. The written job record includes the product name, EPA registration number, and clearance time - documentation you can verify independently.

Will UV light actually prevent mold in my ducts?

UV-C suppresses mold and bacterial growth on the coil and in the immediate plenum area where it’s installed; it does not sterilize the full duct network. In Marietta’s humid climate, we recommend it as part of a maintenance strategy that includes periodic cleaning, not as a standalone solution. We explain exactly what the lamp will and won’t do before quoting installation.

Brands We Service in Marietta

We stock parts and service equipment from Honeywell, Aprilaire, Nikro, and Abatement Technologies - brands whose specifications are published and verifiable. Most common replacement components for Marietta’s installed base of 1990s-2010s systems are available without special order, and we carry UV lamps, media filters, and plenum-mounted purifiers from these manufacturers on our trucks. our brands
