Supply Duct Cleaning in Marietta, GA

Supply Duct Cleaning in Marietta, GA

Wondering how much does air duct cleaning cost? (2026 Price Guide) - Marietta, GA? Supply duct cleaning typically runs between $350 and $650 for a full system, depending on the size of the home and how much debris has accumulated. At Kestrel Air Duct Marietta, we clean the supply side separately from the return side so the air blowing into your rooms isn’t carrying dust from a half-finished job. If you’re noticing dust settling on furniture within days of vacuuming, or certain rooms never seem to hold temperature, your supply ducts are usually the reason. Call us at (762) 533-6494 and we’ll give you a written price before any work begins.

Supply ducts are the highways that carry heated and cooled air from your furnace or air handler into every room of the house. Over years of service, they collect a film of dust, pet dander, skin cells, and in Marietta’s humid summers, sometimes a bit of mold-friendly moisture near the registers. Our full Air Duct Cleaning service addresses the entire system, but this page focuses on the supply side – the ducts that deliver conditioned air to your living spaces.

Dale Whitmore has been running duct cleaning crews in Cobb County for over two decades, and he’ll tell you the same thing he tells every customer: if a company cleans your return ducts and skips the supply side, you’ve paid for half a job. The supply side moves all the air you actually breathe. It deserves the same attention.

When You Need Supply Duct Cleaning

Most Marietta homeowners don’t think about their supply ducts until something visible happens. Here are the signs that usually mean it’s time to call:

• Dust returns within 48 to 72 hours after you clean. You wipe down the coffee table on Saturday, and by Tuesday it’s filmed over again. That dust isn’t coming through open windows – it’s being blown out of your supply registers every time the system cycles on.
• Certain rooms are consistently warmer or cooler than the rest of the house. Supply ducts clogged with debris restrict airflow to specific registers. The room at the end of the longest duct run often suffers first.
• You see gray or black streaks around supply register covers. This is what technicians call “filter blow-by” – air is escaping around a partially blocked register and depositing fine particles on the surrounding wall or ceiling.
• Your energy bills climb during peak summer and winter months. When supply ducts are restricted, the system runs longer cycles to hit the thermostat setting. That’s your money leaking out through reduced efficiency, not a sudden change in Georgia Power’s rates.
• Allergy symptoms flare up indoors but improve when you leave the house. If your sinuses clear up at work and clog again by bedtime, the supply side of your ductwork is likely recirculating whatever’s collected inside it.
• You’ve recently completed renovations or had significant drywall work done. Construction dust settles into ducts and stays there until physically removed. Paint overspray, drywall sanding dust, and sawdust all migrate toward supply registers and sit in the ductwork.

Our Supply Duct Cleaning Process

We don’t guess at what’s in your ducts. Every job starts with a Video Inspection so you see the actual condition, not scary footage used to push a four-figure quote on the spot. The process is straightforward, and it’s the same every time:

1. We inspect the supply side first. Our technician walks the system with you, opening supply registers and checking the duct runs with a camera where needed. You see what we see, before anyone touches a tool.
2. We set up negative-air extraction. A Nikro negative-pressure unit is connected at the air handler. This pulls a vacuum on the entire supply side, so any debris we dislodge gets sucked toward the collection unit instead of blowing back into your living room. In plain English: we create a one-way air current that carries the junk out of your house, not around it.
3. We agitate the duct walls with rotary brush agitation. A Rotobrush system runs a spinning brush through each supply run. The brush physically scrubs the film off the duct walls – dust, pet hair, cobwebs, that gray fuzz that accumulates over years. Just running a vacuum through the ducts without brushing wouldn’t remove what’s actually stuck to the metal.
4. We clean each supply register and boot individually. The register covers come off, get washed, and are reinstalled. The boot – the metal transition piece right behind the register – is hand-cleaned because that’s where the heaviest buildup collects and where brush-only cleaning often leaves residue behind.
5. We run Abatement Technologies HEPA filtration during the entire process. This unit scrubs the air inside your home while we work. The loosened particles that don’t get captured by the negative-air flow are caught by HEPA filtration before they settle on your floors, furniture, or counters.
6. We put the system back together and show you the results. After cleaning, we do a final walkthrough. You can see the difference at the register level, and we’ll show you the collection canister from the Nikro unit so you can see exactly what came out of your supply ducts.

Every step of this process follows the Kingswell Way – the value code we’ve operated under since 2004. That means the price was in your hands before we started, the arrival window was met, the job site is left cleaner than we found it, and the guarantee is in writing.

Supply Duct Cleaning Pricing in Marietta

Most single-family homes in Marietta run between $350 and $650 for supply duct cleaning, with the average falling around $450. Here’s what shapes that range:

• Number of supply runs. A 1,200-square-foot ranch with six supply registers costs less than a 3,500-square-foot two-story with fourteen.
• Accessibility of the air handler. Crawlspace and attic units take longer to set up around. Closet installations in Marietta’s 1970s and 1980s ranch-style homes typically go faster.
• How long it’s been since the last cleaning. If your supply ducts haven’t been touched in 15 years, we’re going to spend more time on each run. That’s not an upsell – it’s just honest scheduling.
• Whether supply and return are being cleaned together. Cleaning the full system is more cost-effective per duct than splitting the job into two visits. Most homeowners choose to do both sides at once.

The price we quote is the price you pay. It’s a written number, in your hands, before a single tool comes off the truck. If we find something unexpected during the job – and occasionally we do – we stop and talk to you before doing anything that would change the cost. No door-step revisions, no “while we’re here” add-ons.

Why Supply Ducts Matter More in Marietta

Marietta’s climate does specific things to ductwork. The long, humid summers mean your air conditioner runs for months at a stretch, and every cycle pulls air across the evaporator coil and pushes it through the supply side. In high humidity, fine dust inside the ducts can absorb moisture and pack down, forming a paste-like layer that’s harder to remove than dry dust. That’s why we don’t use a one-pass, quick-vacuum approach on supply ducts in this area – the buildup Marietta homes develop needs the brush agitation step to actually come off the metal.

Homes near Kennesaw Mountain and the creeks that feed into the Chattahoochee also tend to have higher pollen loads in spring. Pine pollen is notoriously fine – small enough to slip past older filters and settle in the supply side. Once it’s in the ducts, it stays there until someone physically removes it. A standard 1-inch fiberglass filter won’t catch it. What gets past the filter becomes a supply duct problem.

How Supply Duct Cleaning Fits Into the Full System

Your HVAC system has two duct networks: the return side pulls air from your rooms back to the air handler, and the supply side pushes conditioned air back out. They’re connected, but they collect different kinds of debris. The return side catches whatever your filter misses – dust, hair, small particles that float toward the filter grille. The supply side collects what grows and accumulates downstream of the filter, including dust that settles when the system is off and any biological growth that takes hold in humid conditions.

Cleaning one side without the other leaves a lopsided system. A spotless supply side pulling air through a dirty return side will re-contaminate within months. A clean return side feeding a dirty supply side means you’re still breathing whatever’s living in the downstream ductwork. For most Marietta homeowners, the right move is a full Air Duct Cleaning in Marietta service that handles both networks in one visit. If your return side has already been cleaned recently and you’re specifically troubleshooting supply-side issues, we’re happy to quote that scope as a standalone job.

Equipment That Actually Does the Work

You can buy a “duct cleaning kit” at a hardware store for forty dollars. It’s a brush on a flexible rod attached to a drill, and it reaches about four feet into a duct. That’s not cleaning. That’s agitating a small section of the run and hoping for the best.

We run professional-grade equipment designed specifically for full duct systems. The Rotobrush system’s rotary brush travels the full length of each supply run, scrubbing all four walls of the duct, not just the bottom. The Nikro negative-pressure unit creates the vacuum that captures loosened debris at the source. Abatement Technologies HEPA filtration runs during the job to make sure the air in your home stays cleaner than it was when we arrived – we’re pulling particulates out, not redistributing them.

For homeowners who want to keep their supply ducts cleaner between professional visits, we can talk through filtration options from Honeywell and Aprilaire. A high-efficiency media filter or electronic air cleaner installed at the air handler does a substantially better job of keeping fine particulates out of the supply side than a standard fiberglass filter. It’s not a substitute for cleaning, but it lengthens the interval between service visits.

What the 365-Day Done Right Promise Covers

Every supply duct cleaning job comes with our 365-Day Done Right Promise in writing. Here’s exactly what that means:

• If the cleaning doesn’t resolve the issue we diagnosed, we return at no charge. You don’t have to argue, escalate, or prove anything. You call, and we come back.
• The promise covers the scope of work we performed. If we cleaned your supply ducts and you’re still seeing debris blow out of the registers within the guarantee period, that’s on us to fix.
• There’s no paperwork labyrinth to invoke it. Your original service record has the guarantee terms printed on it. You call (762) 533-6494, reference the service date, and we schedule the return visit.
• The promise is not a promotional gimmick. It’s been part of the Kingswell Guarantee since 2004, applied to every job, every time, with no fine print that quietly narrows the coverage.

We put the guarantee in writing because it forces us to do the job right the first time. A company that quietly plans to return and re-clean for free isn’t running a sustainable business. A company that puts its guarantee in writing is telling you it’s confident enough in its process to bet on the outcome. That’s the Kingswell Way.

What to Expect From the Technician

The person who shows up at your door is background-checked, uniformed, and operating under the Kingswell Way values code. That code isn’t a poster in a break room. It’s the standard Dale Whitmore set when he founded the company in 2004, and it governs how every visit works:

• The price is in your hands before work begins, in writing.
• The arrival window we gave you on the phone is the window we hit.
• Your floors are protected, and the job site is left cleaner than we found it.
• You get a plain-English explanation of what was done and what came out of your ducts.
• The guarantee is written on your service record, not implied by a handshake.

If that sounds like a low bar, it is. But ask any Marietta homeowner who’s had a duct cleaning company no-show, or quote one price on the phone and a different one in the driveway, and they’ll tell you how rare it is to find a crew that simply does what it said it would do.

FAQs – Supply Duct Cleaning

How long does supply duct cleaning take in Marietta?

Most supply duct cleaning jobs take between 2 and 4 hours, depending on the number of registers and the accessibility of the air handler. A standard single-story home with eight to ten supply runs typically lands around the 2.5-hour mark. If you’re cleaning both supply and return sides, expect 4 to 6 hours. Call (762) 533-6494 and we’ll give you a realistic time range for your specific home.

How much does supply duct cleaning cost in Marietta?

Supply duct cleaning in Marietta averages $350 to $650 for a full single-family system, with most homes landing around $450. The main variables are the number of supply runs, accessibility, and how much buildup has accumulated since the last cleaning. We quote a written price before work begins, and that number doesn’t change at the door. Estimates are free – call (762) 533-6494.

Is supply duct cleaning worth it if my return ducts were already cleaned?

Yes, if your supply side hasn’t been cleaned separately, it’s still carrying whatever accumulated before the return cleaning. The two networks collect different kinds of debris, and cleaning one doesn’t automatically clean the other. If you’re seeing dust from supply registers or noticing uneven airflow between rooms, a supply-only cleaning addresses the problem directly. For most homeowners, doing both sides in one visit is more cost-effective per duct.

Can supply duct cleaning help with my energy bills?

Restricted supply ducts do force your HVAC system to run longer cycles to reach the thermostat setting, and removing that restriction can reduce runtime significantly. How much you’ll save depends on how clogged the ducts are and how efficient your equipment is overall. The more immediate difference most homeowners notice is more even temperatures between rooms and less dust settling on surfaces. Call (762) 533-6494 for an assessment of your system’s condition.
