AfterHow Much Does Air Duct Cleaning Cost in Marietta?
Air Duct Cleaning Near Me in Marietta, GA typically costs $285 to $485 for a standard single-system home in 2026, with most homeowners paying around $370 for a full cleaning of all supply and return ducts, the air handler, and the main trunk lines. Larger homes with two HVAC systems or extensive ductwork run $500 to $800, while smaller condos and townhomes can often be done for $200 to $275. The price includes negative-air extraction, rotary brush agitation of the duct walls, and a full system inspection, and any reputable Marietta company will put that price in writing before the first vent is opened.
We know that range covers a lot of ground, so below we’ve broken down exactly what you’re paying for, what drives the price up or down in Cobb County specifically, and how to avoid getting quoted one price on the phone and a different one at your door. Kestrel Air Duct Marietta has provided Air Duct Cleaning in this market since 2004, and we’re going to give you the straight numbers.
Air Duct Cleaning Cost Breakdown (2026)
Before we get into the variables, here’s what a typical duct cleaning invoice looks like in Marietta. These are the line items we quote every day, and they’re consistent with what other reputable companies in the area charge.
| Service Component | Typical Cost Range | What It Covers |
|---|---|---|
| Full home duct cleaning (single HVAC system) | $285 – $485 | All supply and return ducts, main trunk lines, air handler, registers, and grilles |
| Full home duct cleaning (two HVAC systems / 3,000+ sq ft) | $500 – $800 | Both systems, all ducts, both air handlers, full register count |
| Condo / townhome / apartment (under 1,200 sq ft) | $200 – $275 | Fewer ducts, shorter runs, single return |
| Air handler / evaporator coil cleaning (add-on) | $75 – $150 | Access panel removal, coil cleaning, drain pan inspection |
| Return-side deep cleaning (add-on) | $60 – $120 | Heavy buildup on return registers and return trunk lines |
| Sanitizing fog treatment (add-on) | $95 – $175 | Antimicrobial fog applied after mechanical cleaning |
| Dryer vent cleaning (often bundled) | $85 – $140 | Lint trap bypass, full vent run cleaning, exterior vent cap check |
Those are the numbers we stand behind in Marietta. If a quote comes in dramatically lower than $285 for a full single-system home, ask what’s being skipped. In our experience, lowball quotes usually mean the company is not pulling a proper negative-air vacuum on the system, or they’re leaving the air handler untouched. We’ve walked into homes off Powder Springs Road where a previous company “cleaned the ducts” for $129 and never actually opened the main trunk line. The homeowner paid twice.
The single biggest driver of cost is the size of the system. A 1,400-square-foot ranch in East Cobb has maybe 10 to 14 registers and short duct runs. A 4,200-square-foot two-story in Indian Hills or West Cobb with a basement system and a separate attic unit has 25 to 35 registers, long trunk lines, and two air handlers to access. That’s not a small job, and the price reflects the labor hours.
What Affects Air Duct Cleaning Pricing in Marietta
Here’s what actually moves the number on your quote, based on what we see in homes across Marietta every week.
- Number of HVAC systems. Homes over about 2,800 square feet in Marietta frequently run two systems, one for each floor. That doubles the air handlers we access, and the duct network is larger. The price roughly doubles, sometimes slightly less because we’re already on site with equipment set up.
- Access to the air handler. In many Marietta homes, the air handler sits in a finished basement, a hallway closet, or a low-clearance attic. Finished spaces require drop cloths and corner protectors. Attics with blown-in insulation make it trickier to work safely. If we need an extension ladder and a headlamp, there’s a modest access charge.
- Age and condition of the ductwork. Older homes near Marietta Square, some dating to the 1960s and 1970s, often have hard-pipe metal ducts wrapped in deteriorating insulation. Those take more care to clean without damaging. Flexible duct in newer neighborhoods, like some of the 1990s and 2000s subdivisions off Barrett Parkway, cleans faster.
- Buildup severity. If you’ve never had your ducts cleaned, or if you run your system year-round during Georgia’s long cooling season, there’s simply more debris on the duct walls. Heavy buildup means slower brush passes and more time spent on each run. Light buildup is faster and costs less.
- Registers and grilles. A home with 10 registers is one thing. A home with 30 registers is another. Each one gets removed, cleaned, and reinstalled. It’s straightforward work, but it adds up in labor time.
- Add-on treatments. The core cleaning price covers mechanical cleaning and extraction. If you want a sanitizing fog after the cleaning, or if the evaporator coil needs attention, those are separate line items. We quote them separately so you can decide, and the price is in writing before we start.
One more Marietta-specific note: the pollen season here runs hard from late March through May, and again in September. Homes with occupants who have allergies or asthma tend to schedule cleanings in May and October, and our schedule fills up. That doesn’t change our pricing, but it does mean you should call a week or two ahead if you want a spring cleaning slot. We answer the phone with a live person, 24/7, so getting on the calendar is never a voicemail waiting game.
How to Save on Air Duct Cleaning
There are honest ways to keep this cost down, and we’ll tell you all of them, including the ones that don’t benefit us.
- Get a written quote before work starts. This sounds obvious, but a surprising number of Marietta homeowners tell us they’ve had prices change at the door. Kestrel Air Duct Marietta puts the price in your hands in writing before a single vent cover comes off. No exceptions, every visit, since 2004. A written quote means you can compare apples to apples.
- Bundle dryer vent cleaning. If your dryer vent hasn’t been cleaned in the last year, adding it to an air duct cleaning visit typically costs less than booking it separately. The equipment is already on site and the technician is already there.
- Schedule in the off-peak window. Late winter, roughly January through early March, is our slowest season in Marietta. Heating systems have been running, so there’s plenty to clean, but the spring rush hasn’t started. Scheduling then is the same price year-round, but you’ll have more flexibility on timing, and we occasionally run seasonal specials.
- Change your filter before calling. A clogged filter doesn’t make the cleaning more expensive, but it does tell us the system has been breathing restricted air. If you replace it before we arrive, the system will run cleaner after we leave, and you won’t be paying for a cleaning that gets immediately re-contaminated.
- Ask what’s included, in writing. The cheapest quote isn’t the best deal if it skips the air handler or doesn’t include the trunk lines. Compare the line items, not just the bottom number.
The best way to get an exact number for your specific home is to call us at (762) 533-6494. Estimates are free, and we’ll walk you through the scope of work in plain language before you commit to anything. You’ll know the price before we ever set foot in your house.
How Kestrel Air Duct Marietta Approaches Duct Cleaning (and What You’re Actually Paying For)
Duct cleaning isn’t a mystery service, and it shouldn’t be priced like one. When we clean a Marietta home, here’s what happens, step by step, because you should know exactly where your money goes.
First, we inspect the system. That means pulling a few registers, looking at the return side, and checking the air handler. We don’t quote a cleaning without seeing what’s actually there. If a company quotes you over the phone without asking about your home’s square footage, system count, or duct type, be wary. That’s how door-step surprises happen.
Second, we run negative-air extraction. In plain English, that means connecting a powerful vacuum (our Nikro units) to the duct system so the entire network is under negative pressure. Anything we dislodge gets pulled toward the vacuum, not pushed into your living room. The vacuum exhaust is filtered, and on our Abatement Technologies units, that means HEPA filtration catching the fine particles that would otherwise go into the air you breathe. Negative-air is the standard for real duct cleaning, and it’s the difference between removing debris and relocating it.
Third, we agitate the duct walls. Negative pressure alone won’t remove debris that’s adhered to the inside of a duct, especially in Georgia’s humidity where dust mixes with condensation and clings. That’s what the Rotobrush rotary brush is for. It’s a spinning brush head on a flexible shaft that travels down each duct run, physically scrubbing the walls so the debris breaks loose and gets carried into the vacuum. No brush, no clean. Simple as that.
Fourth, we clean the registers and grilles. Each one comes off, gets washed, and goes back on. It’s the visible part of the system, but it’s also where a lot of dust and pet hair accumulates on the back side where you can’t see it.
Fifth, we handle the air handler if your Full System Cleaning quote includes it. That means opening the access panel, vacuuming the blower compartment, and cleaning the evaporator coil if it’s accessible. In Marietta’s climate, the coil runs wet for months at a time during cooling season, and it collects a film of dust and microbial growth. Leaving that untouched means you’re cleaning the pipes but not the source.
Our technicians are background-checked and uniformed, and they work under The Kingswell Way, our values code: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, and come back if it fails. It’s not a plaque on the wall. It’s the standard we’ve operated under since the company was founded in 2004.
The 365-Day Done Right Promise in Plain Terms
Every job we do in Marietta comes with the 365-Day Done Right Promise, and we put it in writing on every invoice. Here’s exactly what it covers, so there’s no confusion later.
If the cleaning falls short within one year, meaning the ducts re-contaminate to a degree that indicates the work wasn’t done properly, we return and make it right at no charge. That’s not a pro-rated promise or a courtesy extended if you complain enough. It’s the terms of the job. The Kingswell Guarantee also includes a free second visit if the work fails within the guarantee period. You don’t have to negotiate for it. It’s in writing before we start.
To invoke it, you call us. That’s it. A live person answers, 24/7, and we schedule the return visit. There’s no form to fill out, no claim number, no waiting on a call center. Our Marietta location is independently owned and operated under the Kingswell Guarantee, and the people who answer that phone are the same people who can put a technician back at your door.
We named the company Kestrel for a reason. A kestrel is the small falcon that can hang perfectly still in moving air. That’s what we aim for in this industry: steady, controlled, precise, accountable. It’s a higher standard than “trust us, we’re nice guys.” It means we tell you the price, we do the work, and we back it in writing.
Is Air Duct Cleaning Worth the Cost in Marietta?
That’s a fair question, and we’ll give you a straight answer. For most Marietta homes, yes, once every three to five years is reasonable. Here’s why.
Marietta’s climate is hard on HVAC systems. Cooling season runs from April through October, which means your system cycles constantly for seven months. Every cycle pulls air through the return side, and that air carries dust, pet dander, pollen, and the fine red Georgia clay dust that gets tracked in from yards and driveways. Some of that settles in the ducts. Over time, it’s not just a cleanliness matter; restricted airflow makes your blower work harder, and that’s real wear on equipment that costs thousands to replace.
We also see specific patterns in different parts of Marietta. Homes near the Marietta Country Club and the older tree-lined streets off Whitlock Avenue tend to have more pollen infiltration in spring. Homes in newer subdivisions with construction still underway nearby deal with drywall dust. Homes with pets, regardless of neighborhood, accumulate pet hair and dander faster. None of this is a reason to panic. It’s just a reason to be realistic about what your ducts look like after a few years of Georgia summers.
If you’ve noticed visible dust on your registers, if rooms in your home stay stuffy no matter how you set the thermostat, or if someone in the house struggles with allergies that seem worse indoors, a duct cleaning is a reasonable investment. You can see more about our specific approach on our Air Duct Cleaning in Marietta page.
How Often Should You Clean Air Ducts?
The National Air Duct Cleaners Association recommends every 3 to 5 years for most homes, and that lines up with what we see in Marietta. The exact interval depends on your household.
Homes with multiple shedding pets may need cleaning every 2 to 3 years. Homes with a recent renovation, where drywall dust and construction debris found its way into the system, should be cleaned once the work is finished. Homes with occupants who have severe allergies or respiratory conditions often benefit from a cleaning every 2 to 3 years, and after that point, upgrading to better filtration matters more than more frequent cleaning.
We carry Honeywell, Aprilaire, and Guardsman filtration products for Marietta homeowners who want to maintain cleaner air between service visits. A quality media filter catches far more than a standard one-inch fiberglass filter, and it can extend the practical life of a duct cleaning. We’re happy to show you options, and we’ll never upsell something you don’t need. That’s not the Kingswell Way.
If you’re not sure whether your ducts need cleaning, the simplest first step is a visual check. Remove a couple of registers and look at the duct walls. If you see dust, pet hair, or debris caked on the surfaces, that’s the evidence. For more on what to look for, our home page covers the basics of how to tell when a cleaning is overdue.
FAQs – Air Duct Cleaning Cost in Marietta
How much does air duct cleaning cost in Marietta, GA?
Commercial Duct Cleaning in Marietta costs $285 to $485 for a typical single-system home under 3,000 square feet. Larger homes with two HVAC systems run $500 to $800, and smaller condos or townhomes typically run $200 to $275.

Call (762) 533-6494 for an exact quote on your specific home, estimates are free and you’ll get a written price before any work starts.
Is air duct cleaning cheaper in Marietta than in Atlanta?
Yes, by a modest margin. Marietta pricing runs about $20 to $50 less than intown Atlanta on comparable homes, largely due to lower overhead and easier parking and equipment access in most Cobb County neighborhoods. A job that costs $350 to $400 in Marietta might quote at $380 to $450 in Buckhead or Midtown. The difference isn’t dramatic, so price shouldn’t be the reason you choose a company from outside your area. A local Marietta company that can be at your door same-day is usually the better value.
Can you clean air ducts the same day in Marietta?
In most cases, yes. Kestrel Air Duct Marietta keeps same-day and next-day slots available, and because we answer our phones with a live person 24/7, you’ll know immediately whether we can get to you today. Emergency and next-day duct cleanings carry no extra fee, and the written price you receive is the price you’ll pay regardless of how quickly we get out there. Call (762) 533-6494 to check availability, and you’ll talk to a person, not a recording.
Is it cheaper to clean air ducts or replace them?
Cleaning is dramatically cheaper. Full duct replacement in a Marietta home runs $1,800 to $4,000+ depending on the size of the system and accessibility, while cleaning the same system runs $285 to $485. Replacement is only necessary when ducts are physically damaged, collapsed, infested beyond cleaning, or so deteriorated that they leak. Most ductwork that’s dirty is still structurally sound, and a thorough cleaning restores it. A reputable company will tell you if replacement is genuinely warranted, and Kestrel Air Duct Marietta will always show you the evidence before recommending it.
What should I ask before hiring an air duct cleaning company in Marietta?
Ask for a written price before work starts, ask what the quote includes (air handler or not, trunk lines or not, registers or not), ask what equipment they use (we run Rotobrush rotary brush systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration), and ask what guarantee comes in writing. If a company will not put its guarantee in writing before you pay, walk away. Kestrel Air Duct Marietta has operated under the Kingswell Guarantee since 2004, which means the written price, the written guarantee, and the written promise of a free return visit if the work fails are all in your hands before any work starts. Call (762) 533-6494 and we’ll walk you through all of it.
