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.

AfterCommercial Duct Cleaning in Marietta, GA
Commercial duct cleaning in Marietta covers the inspection, mechanical agitation, and negative-pressure extraction of debris from the supply, return, and exhaust duct networks inside office buildings, retail spaces, restaurants, medical offices, and light industrial facilities. A properly scoped commercial job is not a residential clean with a bigger invoice – it accounts for larger plenum boxes (the main distribution chambers that feed individual duct runs), multiple air handling units, and the kind of sustained contamination that builds up when a building runs its HVAC eight to twelve hours a day, five or more days a week. CleanRun Air Duct Cleaning Marietta has been documenting and cleaning those systems since 2013, and every job – commercial or residential – starts with a written price and ends with a photographic record of every duct run, delivered to the building owner or facility manager as a standard part of the job.
If you manage a commercial property in Marietta and want to know what’s actually inside your ductwork before deciding anything, call us at (470) 516-9337. A live person answers every call, and we’ll give you a written price before a single access panel comes off. That’s Haven Standard Clause 1 – no exceptions, no “call for a quote” runaround.
Commercial duct cleaning is a sub-service of our broader Air Duct Cleaning in Marietta work, and everything that makes our residential process accountable – documented photos, upfront pricing, the 365-Day Done Right Promise – applies here in exactly the same way, scaled to fit a larger system.
When You Need Commercial Duct Cleaning
Most commercial buildings in Marietta don’t run on a fixed cleaning schedule – they run on a “we’ll deal with it when it gets bad” schedule, which means the system is usually well past due by the time someone books an inspection. These are the situations where cleaning moves from maintenance to urgent:
- Visible debris at supply registers or return grilles. When the metal louvers around your registers are coated in a gray or brownish film, that deposit is a surface indicator of what’s coating the interior walls of every duct run upstream. In Marietta’s humid summers, that film often carries mold spores along with ordinary particulate.
- Unexplained odors that vary by zone. A stale or musty smell that’s stronger in one part of the building than another typically points to a localized problem – biological growth or pest intrusion in a specific duct branch. Masking the odor doesn’t address the source; camera inspection does.
- Post-renovation or post-construction work. Drywall dust, insulation fibers, and construction debris migrate into duct systems during any renovation, even when vents are taped. Buildings along Marietta’s Cobb Parkway corridor and around the Barrett Parkway commercial district go through tenant buildouts constantly, and the ductwork almost never gets cleaned afterward.
- Uneven heating or cooling across the floor plate. When certain offices or zones are consistently hotter or colder than others despite a functioning thermostat, partial blockage in the duct runs is a likely cause. Accumulated debris at elbows and transitions restricts airflow and forces the air handling unit to work harder, which raises energy costs.
- HVAC filter load increasing faster than usual. If you’re replacing filters more frequently than your maintenance schedule calls for, the duct system itself is shedding debris back into the airstream. That’s a sign the interior surfaces haven’t been cleaned in long enough for the build-up to become a source rather than just a pass-through point.
- Following a water or moisture event. Any situation where water enters the duct system – a roof leak, a condensate drain overflow, or flooding in a mechanical room – creates conditions for mold growth inside the duct lining. Marietta’s clay soil and variable spring rainfall make basement mechanical rooms and slab-level duct entries particularly vulnerable. A moisture event inside a duct system should be treated as a cleaning and inspection priority, not a wait-and-see situation.
Our Commercial Duct Cleaning Process
We use the same documented, photographed process on every commercial job that we use on full system cleaning for residential work – the difference is scope and equipment scale. Here’s what a commercial clean looks like from start to finish:
- Written scope and price delivered before work begins. Before we schedule a crew, we walk the facility, count the duct runs, identify the number of air handling units, and document the system layout. The written price you receive reflects that specific building – not a per-vent formula applied without looking at what’s actually there. Haven Standard Clause 1 is explicit: no work begins without a signed written price in the customer’s hands.
- Pre-clean camera documentation of every duct run. Every supply and return branch is photographed before any cleaning equipment is introduced. The camera captures the interior wall condition, any visible debris accumulation, and the condition of joints and flex connections. These “before” images are not optional – they’re part of every standard job record and establish an objective baseline that shows exactly what the system contained before we touched it.
- Negative-pressure isolation of the air handling unit. We connect professional-grade collection equipment from Nikro to the air handling unit, creating a sustained negative pressure – essentially a controlled vacuum – across the entire duct network. This draws loosened debris toward the collection point rather than letting it redistribute through the system or settle on interior surfaces elsewhere. The unit runs throughout the agitation phase, which is what separates a professional extraction from a shop-vac pass at a register.
- Mechanical agitation of every duct run. Negative pressure alone doesn’t dislodge debris that has adhered to interior duct walls or liner surfaces. Our technicians use rotary brush systems – including Rotobrush equipment for lined ductwork where applicable – to agitate debris loose from every run before it’s extracted. Elbows and transitions get specific attention because that’s where debris concentrates in any commercial system; the change in airflow direction causes particulate to drop out of suspension and accumulate.
- Plenum and air handling unit component cleaning. The plenum – the main supply or return chamber that distributes air to individual branch runs – is cleaned separately from the branch ductwork because it accumulates a different type and volume of debris. We also clean accessible components inside the air handling unit: coil faces, drain pans, and blower housings, where applicable and within the written scope. Biological growth on evaporator coil faces is a common finding in Marietta commercial buildings where coil maintenance has lapsed.
- Post-clean camera documentation and job record delivery. After extraction is complete, every duct run is re-photographed using the same camera positions as the pre-clean images. The “before and after” photo record is compiled and delivered to the facility manager or building owner as a standard deliverable – not an optional add-on. This record documents what was removed, confirms the cleaning reached the full extent of each run, and gives the customer a concrete reference point for future maintenance intervals.
BeforeAfterCommercial Duct Cleaning Pricing in Marietta
Commercial duct cleaning in Marietta typically runs between $850 and $4,200 depending on the size and configuration of the system. That range reflects real jobs in Cobb County – not a national average pulled from a pricing guide. Here’s what drives the variation:
- Number of supply and return runs: A small professional office suite with a single air handling unit and 12 to 18 duct runs sits toward the lower end of that range. A mid-size retail space or medical office with two or three air handling units and 40 to 60 runs sits toward the upper end.
- System accessibility: Ducts routed through drop ceilings with accessible tiles are faster to work than ducts buried in concrete slab or running through finished mechanical chases that require partial disassembly to access.
- Liner condition: Sheet metal ductwork is faster to clean than fiberglass-lined ductwork. Lined systems require specific rotary brush tools to avoid damaging the liner surface, and the cleaning passes take longer.
- Degree of contamination: A system that hasn’t been cleaned in seven years will take significantly longer per run than one on a three-year maintenance cycle. Our pre-clean camera documentation is what lets us price this accurately – we’re not guessing at contamination level; we’re looking at it.
- Number of air handling units: Each AHU requires its own isolation setup and component cleaning. Multi-unit buildings are priced accordingly.
Every price CleanRun delivers is written, specific to the building in front of us, and fixed before work starts. There are no line items that appear on the invoice that weren’t on the written price. If you have a written estimate from another company, we’ll put our number next to it in writing – that’s our Free Second Opinion, available at no cost.

FAQs – Commercial Duct Cleaning in Marietta
How often should a commercial building in Marietta have its ducts cleaned?
Most commercial facilities in Marietta should schedule duct cleaning every three to five years under normal operating conditions, though certain building types warrant shorter intervals. Restaurants and food service operations accumulate grease vapor in exhaust ductwork much faster than office environments – annual cleaning is standard in those cases and is often required by local fire code. Medical offices and facilities with immunocompromised patients typically clean every two to three years. Any building that has undergone renovation, experienced a water intrusion event, or is showing visible debris at registers should be inspected regardless of the last cleaning date. The pre-clean camera documentation we provide gives you a photographic record to base future scheduling on, rather than a calendar guess. Call (470) 516-9337 for a written assessment of your specific system.
Is commercial duct cleaning disruptive to normal business operations?
For most commercial jobs, disruption is minimal. The negative-pressure extraction equipment operates from the mechanical room or a central access point, and individual duct runs are addressed one section at a time. In occupied office environments, we typically schedule the work during off-hours or over a weekend – that’s a conversation we have during the scope and pricing phase, not an afterthought. The main operational consideration is that the HVAC system needs to be shut down during cleaning, so temperature planning matters in Marietta’s summer months. We’ll tell you exactly how long the system will be offline before you sign anything. Call (470) 516-9337 to discuss scheduling for your facility.
What’s the difference between a commercial duct cleaning and a residential one?
Commercial duct cleaning differs from residential work in three practical ways: system scale, equipment requirements, and documentation complexity. A commercial system typically has multiple air handling units, larger plenum volumes, and duct runs that may span hundreds of linear feet across a single floor. The extraction equipment we use – including Nikro collection units rated for commercial duct volumes – is sized accordingly. The documentation is also more detailed: a commercial job record identifies each AHU separately, documents each branch run individually, and is formatted for facility management records rather than a homeowner file. The process is the same in principle – written price first, camera documentation before and after, negative-pressure extraction throughout – but the scope is calibrated to what a commercial system actually requires.
Does CleanRun clean restaurant exhaust ductwork in Marietta?
Restaurant exhaust duct cleaning, specifically kitchen exhaust hood and grease duct cleaning, is a specialized category governed by NFPA 96 standards and carries different equipment and certification requirements than HVAC duct cleaning. Our commercial duct cleaning service covers HVAC supply, return, and exhaust ductwork in commercial buildings – not grease exhaust systems. If you’re a restaurant owner looking for grease duct cleaning, that work should go to a contractor specifically certified for NFPA 96 hood cleaning. For the HVAC ductwork in your dining room, office, or storage areas, we can help – call (470) 516-9337 and we’ll clarify what falls within our air duct cleaning scope and what doesn’t before any work is scheduled.
Why Marietta Facility Managers Work with CleanRun
Managing a commercial property in Marietta means dealing with vendors who overpromise and underdeliver on a regular basis. CleanRun is built around a different operating model: documented evidence instead of verbal assurances, written prices instead of estimates that expand after the work starts, and a 365-Day Done Right Promise that puts accountability in writing on every job.
The photo record we produce on every commercial clean is not a marketing tool – it’s a facility maintenance document. It shows the building owner or property manager exactly what the duct system contained before we arrived, and exactly what it looked like when we left. That record lives in your maintenance file and gives you a concrete reference point when the next cleaning cycle comes up or when a tenant asks about air quality.
Our technicians are background-checked, uniformed, and identified by name before they arrive on site – Haven Standard Clause 3: Verified Crews. That matters in a commercial setting where you’re responsible for who is in your building and what they’re doing there.
Since 2013, we’ve served more than 52,000 properties across the Marietta area, every one of them with a written price before the work started and a documented photo record when the crew left. If you want to see what’s inside your commercial duct system before making any decisions, that’s exactly the right instinct – and it’s exactly what we’re set up to show you.
