Cardinal Air Duct Marietta handles everything from single-tenant medical suites to multi-floor office buildings, and we always provide a written price before any equipment comes off the truck. If you manage a commercial property in Marietta and the vents are pushing out dust every time the HVAC cycles on, call (762) 216-4075 for a free walkthrough and estimate.

We’re part of the Relay Home Co. family, founded in 2005, and we operate under The Relay Visibility Guarantee: you get a live trackable arrival time, before-and-after photos, and a digital invoice you can pay from your phone. That level of transparency matters more in commercial work than anywhere else, because when your tenants, employees, or customers are affected, you need to know exactly what was done and exactly what it cost. We also handle residential Air Duct Cleaning in Marietta, so if you manage a mixed-use building or have tenants who ask about their own spaces, we cover both.

Every commercial job is led by Omar Haddad and backed by the 365-Day Done Right Promise: if the work isn’t right within a full year, we return and correct it at no charge. That’s not a limited-time offer. It applies to every commercial cleaning we book, without exception.

When You Need Commercial Duct Cleaning

Commercial HVAC systems in Marietta move a lot of air. An office that runs its rooftop units 10 to 12 hours a day will pull the same cubic footage through its ducts hundreds of times a week. When those ducts are dirty, the entire building pays for it in higher energy bills, shorter equipment life, and indoor air that makes employees and customers uncomfortable. Here are the most common signs we see across Marietta commercial properties, from the office parks along Powers Ferry Road to the retail strips off Canton Road:

• Dust accumulating quickly on surfaces near vents. If desks, merchandise shelves, or exam tables need wiping down every couple of days, the ducts are likely redistributing dust from deep inside the system.
• HVAC smells when the system kicks on. A musty or stale odor at the start of a cooling cycle often points to microbial growth or accumulated debris in the return ductwork, especially in buildings around the Chattahoochee River where summer humidity is relentless.
• Tenant or employee complaints about allergies or dryness. Marietta’s pollen season runs from February through May, and a dirty commercial system can trap and recirculate that fine particulate long after the trees stop blooming.
• Uneven heating or cooling between rooms. If the conference room stays warm while the hallway is freezing, restricted airflow from buildup in the ductwork is a common culprit, particularly in buildings with long main trunk lines.
• Visible dust puffs from supply registers when the fan starts. That is the single clearest sign the ducts need cleaning now, not next quarter. It means the system has enough loose debris to blow out continuously.
• Renovation or construction dust in the building. If you’ve had drywall work, ceiling tile replacement, or any construction inside the past year, fine particulate gets into the duct system and can remain there for years without proper extraction.

If you’re seeing two or more of these, the smart move is a professional inspection. We can do that quickly and tell you honestly whether the ducts need attention or whether the issue is something else entirely, like a failing blower motor or an undersized unit.

Our Commercial Duct Cleaning Process

We follow a clear, repeatable sequence on every commercial job. No shortcuts, no vague “we’ll clean the mains and call it a day.” Here’s what you can expect when Cardinal Air Duct Marietta handles your commercial ductwork:

1. Walkthrough and written estimate. Omar Haddad or one of our lead technicians walks the building with you, checks the air handler, inspects accessible duct runs, and asks about occupancy schedules and any hot-button areas. You get a written price before we touch anything. That price does not change at the door.
2. Containment setup. We seal off supply and return registers using professional containment units from Abatement Technologies. This keeps negative air pressure inside the duct system while we work, so loosened debris cannot escape into occupied areas.
3. Agitation and loosening. We run rotary brush systems through the ductwork to mechanically dislodge the years of built-up dust, hair, construction debris, and microbial material. On large commercial mains, we use extended-reach agitation tools to cover the full length of each run, not just the first 10 feet from the register.
4. Negative-pressure extraction. Our Nikro HEPA-rated vacuum units pull the loosened debris out of the duct system and directly into sealed containment. Negative-pressure extraction means the air inside the ducts stays under suction the entire time, so anything we dislodge goes straight into the vacuum, not back into your offices, kitchen, or exam rooms.
5. Component cleaning and optional sanitization. We clean accessible plenums, turning vanes, and the air handler surfaces. If your building needs it, we can apply an EPA-registered sanitizer to interior duct surfaces to address microbial growth. We’ll explain exactly what that involves and what it costs before adding it to the scope.
6. Documentation and final walkthrough. You get before-and-after photos of every major duct run, coil surface, and plenum we touched. Then we do a final walkthrough together, confirm the system is running properly, and email you a digital invoice you can pay from a link. No paper chase, no surprise charges.

Most Marietta commercial jobs are completed in one to two business days, depending on the square footage and number of rooftop units. We can work nights and weekends for restaurants, medical offices, and other businesses that can’t close during operating hours.

Commercial Duct Cleaning Pricing in Marietta

We quote every commercial job individually because a 1,200 sq ft dental office and an 18,000 sq ft multi-tenant building have very different needs. That said, here’s what you should expect to budget based on what we’ve seen across Marietta and Cobb County over the past several years:

Building Type	Typical Size	Typical Price Range
Small office or medical suite	1,000 – 2,500 sq ft	$900 – $1,800
Restaurant or cafe	1,500 – 3,500 sq ft	$1,400 – $2,600
Retail storefront	2,000 – 5,000 sq ft	$1,600 – $3,200
Mid-size office building	5,000 – 12,000 sq ft	$2,800 – $5,200
Light industrial or warehouse	10,000 – 25,000 sq ft	$4,200 – $9,500
Medical or lab facility	Variable	$0.45 – $0.65 per sq ft

What drives the price? Four main factors. First, the number of rooftop units (RTUs) and air handlers, since each unit has its own blower cabinet and coil that need attention. Second, the total linear footage of accessible ductwork. Third, the building’s occupancy schedule, which may require night or weekend work for restaurants and healthcare tenants. Fourth, the level of contamination. A system that hasn’t been cleaned in 12 years costs more than one that was done 3 years ago.

Every quote we provide is a written, line-item price. You’ll see exactly what you’re paying for and what you’re not. No per-vent “upcharge games,” no upsell blitz once we’re inside. Estimates are free. Call (762) 216-4075 to schedule a walkthrough, and Omar will walk the building with you and get you a number you can act on.

We also carry professional-grade filtration products from Honeywell and Aprilaire, which we can install if your building would benefit from upgraded media filtration at the air handler level, especially useful for medical offices, child care centers, and any business where indoor air quality is a client-facing concern.

Commercial Properties We Serve in Marietta

We’ve cleaned duct systems across every major commercial corridor in Marietta. We work regularly in office parks along Powers Ferry Road and Windy Hill Road, retail centers near Town Center at Cobb, restaurants around the Marietta Square, and medical and dental offices along Church Street and Johnson Ferry Road. We also serve the industrial and flex spaces near Dobbins Air Reserve Base and the warehouse district east of I-75.

What makes commercial work in Marietta unique is the climate. Summers here run hot and humid from June through September, which means your HVAC pulls moisture out of the air constantly. If the evaporator coil is dirty, that moisture doesn’t drain properly, and you end up with water in the drain pan, microbial growth on the coil, and that stale smell tenants complain about. A clean duct system alone won’t cure a dirty coil, which is why every commercial cleaning we do includes coil inspection and cleaning when needed.

If your business operates in nearby communities, we also serve commercial clients in Kennesaw, Smyrna, Woodstock, Acworth, Roswell, Alpharetta, Sandy Springs, Mableton, Powder Springs, and Dunwoody. We can schedule multi-location portfolios for property managers who oversee several buildings across Cobb and North Fulton counties.

Why Building Owners and Property Managers Choose Cardinal

We’re not the cheapest commercial duct cleaner in Marietta, and we won’t pretend to be. What we offer is total visibility. You know the technician’s name before they arrive because they’re background-checked and uniformed. You get a live arrival window you can track from your phone, not a four-hour block of “we’ll get there when we get there.” You get written documentation of what was done, with photos. And every commercial job falls under the same 365-Day Done Right Promise we give residential customers: if the work isn’t right within 365 days, we return and correct it at no charge.

The Relay Standard, the operating model for all Relay Home Co. businesses since 2005, is built on exactly this: live trackable arrival times, before-and-after photo proof, written pricing before work begins, and digital invoicing. We don’t do handshake quotes or cash-only paperwork. For a commercial property manager pulling together maintenance records, that documentation is gold.

Our equipment fleet includes rotary brush systems from Rotobrush, HEPA-rated negative air machines from Nikro, and professional containment units from Abatement Technologies. That means the debris we loosen inside your ducts is actively pulled into sealed filtration, not blown around the building by a shop vac strapped to a truck.

FAQs – Commercial Duct Cleaning

How much does commercial duct cleaning cost in Marietta, GA?

Commercial duct cleaning in Marietta typically runs between $0.35 and $0.55 per square foot, with most small to mid-size buildings landing between $1,800 and $4,200 total. The exact number depends on how many rooftop units you have, how much ductwork is accessible, and how long it’s been since the last cleaning. Call (762) 216-4075 for a free walkthrough and line-item estimate, no obligation.

How long does commercial duct cleaning take?

Most commercial duct cleaning jobs in Marietta are completed in one to two business days. A single-tenant office under 2,500 sq ft is typically done in a day. Multi-floor buildings or restaurants with grease-laden duct runs may take longer, and we can schedule nights or weekends so you don’t close during business hours. We’ll give you a clear timeline in your written estimate.

Is commercial duct cleaning worth the cost?

For most Marietta commercial properties, yes, especially if the building hasn’t had its ducts cleaned in 5 or more years or has had recent renovation work. Clean ducts improve airflow, reduce strain on rooftop units, and help keep the air inside your building from circulating accumulated dust and debris. Many of our commercial clients schedule cleaning every 3 to 5 years as part of their preventive maintenance plan.

Do you clean restaurant exhaust hoods and kitchen ducts?

We focus on HVAC air duct cleaning, not kitchen exhaust hoods or grease duct remediation. Those systems require specialized grease-rated cleaning services. If your restaurant needs HVAC supply and return duct cleaning for the dining room and kitchen areas, we handle that, but we’ll refer you to a trusted grease exhaust specialist for the hood itself.

Can you work around my business hours?

Yes. We schedule commercial cleaning for nights, early mornings, and weekends across Marietta and Cobb County. Restaurants, medical offices, and retail stores can keep normal hours while we work. Let us know your occupancy schedule during the estimate, and we’ll build the job around it.
