Supply Duct Cleaning in Marietta, GA

Supply Duct Cleaning in Marietta, GA

Supply duct cleaning in Marietta typically costs between $180 and $420 for most single-family homes, depending on square footage and how long it’s been since the last cleaning. Supply ducts are the arteries of your HVAC system – the metal or flexible tubes that carry heated and cooled air from your furnace or air handler to every vent in your house. When those ducts carry dust, pet dander, or construction debris along with the air, you’re breathing it every day.

At Cardinal Air Duct Marietta, we clean supply ducts with professional-grade negative-pressure extraction. That means the loosened debris goes straight into a Nikro HEPA-rated vacuum – not back into your living room. Our full-service Air Duct Cleaning covers supply ducts, return ducts, the air handler, and registers, but many Marietta homeowners ask us to focus on supply duct cleaning specifically, especially after renovations or when one room consistently underperforms. Call us at (762) 216-4075 for a free estimate on supply duct cleaning – a live person answers, day or night.

When You Need Supply Duct Cleaning

Supply ducts are the only part of your HVAC system that touches every single room. Over time, they collect whatever moves through your Cobb County home – dust from Cherokee Street traffic, pollen from the Kennesaw Mountain ridgelines, drywall dust from that Powder Springs bathroom remodel. Here’s when Marietta homeowners call us:

• You see dust blowing from vents when the AC kicks on. That puff of fine gray dust is a direct sign that debris has accumulated in your supply runs and is being pushed into the room.
• A recent renovation left construction dust everywhere. Drywall sanding, floor refinishing, and trim work in East Cobb and West Cobb homes produce fine particulates that settle into supply ducts and keep recirculating for months.
• One or two rooms are noticeably stuffier or smell musty. Supply ducts serving those rooms may have restricted airflow or mold growth, especially in Marietta’s humid summers when condensation forms inside duct runs in unconditioned attics.
• Your energy bills have climbed without a change in usage. A supply duct with a quarter-inch of buildup forces your blower to work harder to push air through the restriction, which shows up on your Georgia Power bill.
• You have a family member with allergies or asthma. Marietta’s spring pollen season runs long – from late February through May – and supply ducts act as a reservoir that keeps releasing allergens indoors long after the season peaks.
• You’ve never had the ducts cleaned in a home you’ve owned for 5+ years. The National Air Duct Cleaners Association recommends cleaning every 3 to 5 years, and many homes we service in the Sprayberry and Lassiter school districts haven’t been touched since construction.

If any of these sound familiar, you’re not alone. We see these exact patterns in homes throughout Marietta’s 30008, 30060, 30062, 30064, 30066, 30067, and 30068 ZIP codes. Supply duct cleaning solves the root cause rather than treating the symptom over and over.

Our Supply Duct Cleaning Process

We came up in this trade watching companies send a single tech with a shop vac and a flashlight. That’s not duct cleaning – that’s theater. Here’s how Cardinal Air Duct Marietta handles supply duct cleaning, step by step:

1. Walkthrough and written price. We walk the home with you, identify every supply register, check access points, and hand you a written price before any work starts. That price does not change at the door – it’s part of The Relay Standard we hold to on every job.
2. Containment setup. We use Abatement Technologies containment equipment to create negative pressure in the duct system. That means air only moves one direction – out of your ductwork and into the vacuum. No dust bloom into hallways or bedrooms.
3. Register cleaning and inspection. Every supply register comes off, gets cleaned, and we visually inspect the first few feet of each duct run with a camera before we start. This tells us what we’re dealing with – dust, debris, mold, or even a critter.
4. Mechanical agitation. We connect our Rotobrush rotary brush system to each supply run. The brush breaks the debris bond from the duct walls – this is the step that separates professional cleaning from a vacuum-only job. Dust that’s adhered to duct walls doesn’t move with suction alone.
5. HEPA vacuum extraction. The Nikro HEPA-rated vacuum pulls the loosened material out of the supply ducts and traps it in a sealed filtration system. HEPA filtration captures 99.97% of particles down to 0.3 microns – which matters when you’re dealing with the fine particulates that actually reach your lungs.
6. Verification photos. Before we pack up, we run the camera again and show you before-and-after photos of your supply ducts. You see what we saw, and you see the result. If we missed something, we correct it on the spot – that’s what the 365-Day Done Right Promise is built for.

Most supply duct cleaning jobs in Marietta take 2 to 4 hours, depending on home size and the number of supply runs. You’ll know your tech’s name before they arrive, they’ll be in uniform and background-checked, and you’ll get a live arrival window you can track from your phone.

What Gets Removed From Supply Ducts

When homeowners in Marietta ask what’s actually in their supply ducts, the answer depends on the home’s history, but these are the common culprits:

• Drywall dust and paint overspray from construction or renovation. Homes built or remodeled in the last 5 years around the Marietta Square and Franklin Road corridor often have significant construction debris in supply runs.
• Pet hair and dander that works past the filter, enters the air handler, and gets distributed through supply ducts. This accumulates fastest in homes with multiple pets.
• Pollen – especially hardwood pollen from the mature oaks in East Cobb neighborhoods like Indian Hills and Fox Hills, which gets pulled into the return side and pushed through the supply side in spring.
• Dust mites and their byproducts, which thrive in Marietta’s humidity when supply ducts run through unconditioned attic spaces and condensation forms.
• Mold spores – and in some cases, active mold growth – in supply duct runs that have experienced moisture intrusion from leaking AC condensate lines or roof penetrations.
• Insect and rodent debris in older homes where duct runs have gaps or disconnected seams in crawlspaces.

Whatever we find, we’ll show you the Video Inspection camera footage. Total visibility is the point – and it’s what separates Cardinal Air Duct Marietta from the companies that quote over the phone and disappear into your attic for an hour.

Supply Duct Cleaning Pricing in Marietta

Let’s talk numbers, because we think you deserve a straight answer before you decide anything. Here’s How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Marietta, GA in the Marietta market at the time of writing:

Home Size	Typical Supply Duct Cleaning Range	What’s Included
Up to 1,500 sq ft	$180 – $250	All supply runs, registers, containment, before/after photos
1,500 – 2,500 sq ft	$250 – $340	All supply runs, registers, containment, before/after photos
2,500 – 4,000 sq ft	$340 – $420	All supply runs, registers, containment, before/after photos
Over 4,000 sq ft or multi-zone	Custom quote	Full walkthrough and written price before work begins

What affects the price in Marietta specifically:

• Square footage and number of supply registers. A 1,200 sq ft ranch in the Allgood Road area with 8 supply registers is a different job than a 3,800 sq ft two-story in West Oak with 16.
• Access to duct runs. Attic-accessible supply ducts are straightforward. Crawlspace-accessed runs – common in older Marietta homes near the historic district – take longer and cost a bit more.
• Condition of the ducts. If supply runs are heavily loaded with construction debris or show signs of moisture damage, the job takes longer. We’ll see it on the camera during the initial inspection and adjust the written quote before we start.
• Flexible vs. rigid ductwork. Most Marietta homes built since the 1990s use flexible duct. Older homes may have rigid sheet metal runs that clean differently and sometimes hold up better over time.

Here’s the thing: we don’t quote over the phone without seeing the house, and we don’t charge more once we’re inside. The price you get in writing at the walkthrough is the price on your invoice. Period. Call (762) 216-4075 and we’ll schedule a free walkthrough and give you an exact number.

Supply Duct Cleaning vs. Full Air Duct Cleaning

You might be wondering if you can save money by cleaning only the supply side and leaving the returns alone. Here’s our honest take as the people who do this work every day in Marietta:

Supply-only cleaning makes sense in specific situations. If you just finished a kitchen remodel and the drywall dust got pulled into the supply side only – or if a single room’s supply run is obstructed – a targeted cleaning can solve the immediate problem. We’ll do it, and we’ll price it fairly.

But in most homes, the supply and return sides share the same air. Contaminants pulled through the return grilles enter the air handler and circulate through the supply side. Cleaning only the supply ducts leaves the return side to keep feeding particles into the system. A full Air Duct Cleaning addresses the whole loop – and in many cases, the total cost of a full-system clean is only $80 to $150 more than supply-only. We’ll give you both numbers in writing so you can decide with full information.

FAQs – Supply Duct Cleaning

How much does supply duct cleaning cost in Marietta?

Supply duct cleaning in Marietta typically costs between $180 and $420 for most single-family homes, depending on square footage, number of supply registers, and access to the duct runs. Homes over 4,000 sq ft or with multi-zone systems require a custom walkthrough quote. Every Cardinal Air Duct Marietta job includes a written price before any work starts, and that price never changes at the door. Call (762) 216-4075 for a free estimate – we’ll give you an exact number after we see the house, not before.

How often should supply ducts be cleaned in Marietta?

Most Marietta homes benefit from supply duct cleaning every 3 to 5 years, though homes with pets, recent renovations, or allergy-sensitive family members may need it more often – every 2 to 3 years. Marietta’s long pollen season and high summer humidity also accelerate buildup in supply runs. If you’ve never cleaned the supply ducts in a home you’ve owned for more than 5 years, it’s time for an inspection.

What’s the difference between supply duct cleaning and return duct cleaning?

Supply ducts carry conditioned air from your furnace or air handler to the rooms. Return ducts pull air from the rooms back to the system to be reheated or cooled. Supply ducts tend to collect dust, pollen, and pet dander that gets past the filter, while return ducts often collect more airborne particles from the living space. Both sides matter, and cleaning only one leaves the other feeding contaminants into the system. We price supply-only and full-system options so you can decide.

Can you clean supply ducts without replacing them?

Yes – in the vast majority of Marietta homes, supply ducts can be thoroughly cleaned with professional equipment without replacement. Our Rotobrush rotary brush system and Nikro HEPA vacuum remove debris from inside the duct runs. Replacement is only needed when ducts are physically damaged, disconnected, or have active mold growth that has penetrated the material. We’ll always show you camera footage so you can see the condition of your ducts before deciding.

How long does supply duct cleaning take?

Most supply duct cleaning jobs in Marietta take 2 to 4 hours, depending on home size, number of supply runs, and the level of buildup. Smaller single-story homes run shorter; larger two-story homes with crawlspace-accessible ducts run longer. You’ll get a live arrival window you can track, and you’ll see before-and-after photos before we leave.

Will supply duct cleaning help with allergies in Marietta?

Supply duct cleaning removes the reservoir of pollen, pet dander, dust mite particles, and mold spores that sits inside your duct runs and gets pushed into your rooms every time the system runs. In Marietta’s heavy pollen seasons, that reservoir keeps releasing allergens indoors long after the outdoor count drops. For homes with allergy or asthma sufferers, supply duct cleaning is often a meaningful improvement – especially when paired with a good filtration strategy. Ask us about Aprilaire and Honeywell filtration options when you call.
