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

Air Duct Cleaning in Marietta, GA

HVAC cleaning in Marietta typically runs $380-$620 for a complete system, with most jobs scheduled within 3-5 business days. The city’s concentration of 1960s-1980s ranch and split-level homes means we regularly encounter fiberglass ductboard trunks and early flex duct that require different handling than modern metal systems. Our crews dispatch from the Atlanta office and carry Rotobrush and Abatement Technologies equipment sized for these older configurations. Call (470) 326-1926 for a written estimate before any work begins.

Why Marietta Homes Are Different

Marietta’s post-war expansion built tens of thousands of homes with fiberglass ductboard trunk systems and thin flex branches routed through unconditioned attics. After 40-60 years, the inner liner of that ductboard degrades and sheds glass fibers into the airstream, a problem invisible without camera inspection. In summer, those attics hit 140-150°F, accelerating material breakdown.

Metro Atlanta’s pollen season, consistently among the nation’s worst for oak, pine, and sweet gum, overwhelms the 1-inch filter slots common in these homes. Heavy particulate loads pack into return-air duct runs. We also find a distinct failure pattern: flex branches added in the 1990s onto 1970s ductboard trunks, connected with tape that has dried and separated. The system pulls unconditioned, pollen-laden attic air directly into the living space. That two-phase construction history makes Marietta jobs more complex than work in newer neighboring cities.

Our Main Marietta Services

Homeowners in Marietta call us most often for these three services.

Air Duct Cleaning in Marietta

We clean the full duct network: supply runs, return runs, trunk lines, and plenum boxes, using negative-pressure extraction with Rotobrush contact agitation. In Marietta’s older homes, we pay particular attention to ductboard transitions where debris packs behind sagging flex connections. Every run is photographed before and after.

Dryer Vent Cleaning in Marietta

Dryer vent blockages in Marietta’s 1970s-1980s ranch homes often occur where vents terminate through roof jacks or long horizontal runs under the slab foundation in split-levels. We clear the full line from appliance to termination and verify airflow with a manometer. Dryer Vent Cleaning in Marietta

Duct Repair & Sealing in Marietta

Separated tape joints, crushed flex branches, and degraded ductboard trunks are standard findings here. We replace damaged sections with metal where appropriate and seal accessible joints with mastic. Every repair is photographed and documented in the job record. Duct Repair & Sealing in Marietta

HVAC Cleaning in Marietta

HVAC cleaning in Marietta addresses the equipment that moves air through those aging duct systems: the evaporator coil, blower assembly, condenser, and air handler. The same humid attic conditions that degrade ductboard also coat coils with biofilm and dust, reducing efficiency and circulating musty odors. We perform HVAC Cleaning with equipment matched to each component’s access constraints.

Evaporator Coil Cleaning

Signs you need it

Ice buildup on refrigerant lines, weak airflow from registers, or a musty smell when the AC first cycles on.

What it costs in Marietta

Evaporator coil cleaning typically runs $180-$340 depending on access panel configuration and contamination level.

How we do it

We remove the access panel, apply foaming cleaner to the coil fins, rinse with low-pressure water capture, and photograph the before and after condition.

Blower Cleaning

Signs you need it

Vibration noise from the air handler, uneven airflow room to room, or dust puffing from registers at startup.

What it costs in Marietta

Blower assembly cleaning typically runs $160-$280 based on motor type and housing complexity.

How we do it

We remove the blower wheel and housing, clean each blade with compressed air and solvent, vacuum the housing cavity, and reassemble with torque verification.

What HVAC Cleaning Costs in Marietta

How do I know my HVAC system needs cleaning versus just the ducts?

If you smell must when the AC cycles, see ice on refrigerant lines, or hear vibration from the air handler, the equipment itself needs attention. Duct-only cleaning won’t resolve these symptoms. Call (470) 326-1926 and we’ll inspect both the duct network and the mechanical components to identify the source.

Can HVAC cleaning improve my energy bills in Marietta’s climate?

Yes, a coated evaporator coil or clogged blower can reduce system efficiency by 15-25%, which matters significantly during Marietta’s July and August cooling load. We document the before condition so you can see the restriction. Call (470) 326-1926 for a written estimate.

Air Quality & Sanitizing in Marietta

Air quality and sanitizing in Marietta targets the microbial load that thrives in humid attic duct systems and on wet evaporator coils. The same moisture infiltration that degrades ductboard creates conditions for mold colonization inside unsealed return plenums. We perform Air Quality & Sanitizing with application-specific products from Guardsman and Abatement Technologies, photographed before and after.

Mold Treatment

Signs you need it

Visible black or green growth on register faces, a persistent earthy odor, or allergy symptoms that worsen when the system runs.

What it costs in Marietta

Attic-accessible mold treatment typically runs $280-$480 per affected zone based on square footage and accessibility.

How we do it

We apply EPA-registered antimicrobial foam to affected duct surfaces, allow dwell time per manufacturer specification, and extract residue with negative-pressure equipment.

UV Light Installation

Signs you need it

Repeated mold recurrence after cleaning, chronic musty odor, or a household member with immunocompromise.

What it costs in Marietta

UV-C lamp installation at the evaporator coil typically runs $320-$520 including the lamp assembly and electrical connection.

How we do it

We mount the lamp assembly downstream of the coil with a sight-glass port, wire to the blower relay for automatic operation, and verify UV output with a radiometer.

What Air Quality & Sanitizing Costs in Marietta

Is mold in my ducts common in Marietta, or am I overreacting?

In Marietta’s climate, mold in unsealed attic ductwork is common, not exceptional. The combination of humidity and 140°F attic temperatures creates ideal conditions. We find active growth in roughly one-third of homes built 1960-1985. Call (470) 326-1926 for camera inspection and a written scope.

Will UV lights actually prevent mold, or is that marketing?

UV-C at 254nm wavelength disrupts mold DNA and prevents colonization on irradiated surfaces when properly positioned and maintained. The lamp must sit where it bathes the coil and drain pan continuously. We install with a sight-glass so you can verify operation. Call (470) 326-1926 for specifications.
