Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Why Hollis Air Duct Cleaning Is Marietta’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning operation runs on The Garrison Standard: arrive inside the quoted window, price in writing before touching equipment, complete the job by the book, and leave the site clean. That standard matters in Marietta because homeowners here have seen the alternative – crews who quote low over the phone, then discover “problems” that double the bill once they’re inside.
Our technicians are background-checked and uniformed. You know who’s arriving before they pull into your driveway. Phones are answered by a live person 24 hours a day, seven days a week – no voicemail loops, no callback queues, no waiting until Monday for a scheduling question.
The 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. That guarantee is backed by operational specifics, not adjectives: we document what we found, what we did, and what the homeowner should expect afterward.
Air Duct Inspection in Marietta
Air Duct Inspection in Marietta is the first step we recommend for any homeowner who smells musty air from their registers, notices uneven airflow between rooms, or has just closed on a new build and wants to know what the builder left behind. If we find leaks during inspection, we also offer Duct Sealing - Marietta to restore efficiency. Our techs use video inspection cameras to document the interior condition of your supply and return ducts, the air handler compartment, and the evaporator coil. In Marietta’s older homes near the square, we often find fiberglass duct board from the 1970s – 80s that has absorbed years of humidity and pollen; in newer subdivisions, we find construction debris settled in sagging flex runs that a standard builder clean missed entirely. A typical inspection in Marietta runs $150 – $250, and we apply that fee toward your cleaning if you proceed.
What the Camera Reveals
The video feed shows you exactly what we’re seeing: dust accumulation, biological growth, construction debris, or damaged duct liner. No guesswork, no scare tactics. You watch the monitor while we narrate what the image means for airflow and air quality.
When to Schedule
Schedule an inspection if you’ve never had your ducts cleaned, if you’ve recently renovated, if you notice persistent odors, or if your new build is under two years old. In Marietta’s humid climate, mold can establish within 12 – 18 months in undisturbed debris.
Residential Air Duct Cleaning in Marietta
Residential Air Duct Cleaning in Marietta covers the full HVAC duct network: supply ducts, return ducts, air handler, registers, and grilles. We use Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines to maintain controlled suction and HEPA filtration throughout the job. For Marietta’s mid-century ranch homes with original galvanized ductwork, this means working carefully around corroded seams; for newer flexible duct systems, it means adjusting brush speed and pressure to avoid tearing the inner liner. A typical residential cleaning in Marietta runs $350 – $650 depending on system size, accessibility, and contamination level. We price by the complete system, not per vent, and that price is written down before we start.
Construction Debris in New Builds
A family in the Whitlock Avenue corridor called us three months after closing on a new build because every register in the house was puffing white dust onto the furniture. Our tech pulled the air handler panel, found drywall dust and chunks of torn poly sheeting sitting in the blower motor compartment, and ran a camera inspection down the sagging flex run feeding the master suite. We set up negative pressure with HEPA filtration, worked the debris loose with agitation tools, and the supply and return ducts have run clean since the second visit.
The Humidity Factor
Marietta’s humid subtropical climate keeps HVAC systems running almost year-round, and the constant moisture means ductwork never fully dries out. Combine that with spring pollen loads heavy enough to coat cars in yellow-green film, and you’ve got conditions that feed microbial growth in any debris left sitting inside the system.
Trusted Brands We Service in Marietta
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use, not hardware-store gear. For Marietta homeowners, that means we can source replacement filters, media, and components without extended delays – we stock common sizes and configurations locally, and our Atlanta office coordinates same-day or next-day parts for less common setups. When we recommend a filtration upgrade after cleaning, we’re specifying products we’ve installed and serviced, not reading from a catalog.
Common Air Duct Cleaning Problems We See in Marietta Homes
- Construction dust in new subdivisions. Builders in Marietta’s east and northeast-side developments often fail to cap registers during drywall sanding, pulling dust straight into supply and return ducts. The one-time “builder clean” before move-in typically misses low points in sagging flex runs where debris concentrates.
- Mold in original fiberglass duct board. Homes near Marietta Square with 1970s – 80s duct board have insulation that absorbed decades of humidity and pollen. Cleaning helps, but the musty smell often returns because the material itself is compromised – replacement is the real fix.
- Corroded galvanized steel in mid-century ranches. The 1950s – 1970s housing stock throughout central Marietta used galvanized ductwork that corrodes from the inside out. We find fragmentation and rust scale that restricts airflow and provides surface area for biological growth.
- Clogged evaporator coils from deferred cleaning. New owners postpone duct cleaning because the house is brand new, letting drywall dust sit against the blower motor and clog the evaporator coil through the first humid Marietta summer. The result is reduced cooling capacity and higher energy bills.

FAQs About Air Duct Cleaning in Marietta
Because builders rarely cap registers during drywall sanding, construction dust and debris get pulled directly into your supply and return ducts the first time the HVAC system runs. In Marietta’s east and northeast-side subdivisions, the flexible duct runs sag at their low points, so drywall dust and framing debris settle there instead of blowing through – a problem that barely shows up in Atlanta’s new-build high-rises with short, taut trunk runs. Call (361) 326-5060 for a free inspection if you’re seeing dust from registers in a home under two years old.
It clogs the blower motor, coats the evaporator coil, and reduces airflow throughout the house. In Marietta’s humid climate, that dust provides a substrate for mold and mildew growth once moisture condenses on it. The result is reduced cooling capacity, higher energy bills, and musty air from registers – sometimes within the first summer. Call (361) 326-5060 for an inspection and written quote.
We recommend within the first 3 – 6 months, before the first full cooling season. That timing lets you catch construction debris before it migrates from the ducts into the air handler and before Marietta’s humidity converts settled dust into a mold substrate. Waiting a full year often means the debris has already caused coil fouling or blower strain. Call (361) 326-5060 to schedule.
Yes. High-pressure whip systems, sometimes used by cleaners who skip NADCA standards, can tear the inner liner of flexible ductwork and leave fiberglass fragments circulating through your supply and return ducts permanently. We use controlled rotary brush agitation with adjustable speed and negative-air containment – enough to dislodge debris, not enough to damage the duct. Call (361) 326-5060 and we’ll explain our process before quoting.
No. A high-MERV filter traps particles at the return grille, but it cannot remove dust already settled in duct low points or lodged in the blower compartment. In fact, running a restrictive filter on a system already partially clogged by construction debris can overwork the blower motor and accelerate failure. Physical removal is required. Call (361) 326-5060 for a video inspection to see what’s actually inside your ducts.
