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.

AfterSupply Duct Cleaning in Johns Creek, GA
Supply duct cleaning focuses specifically on the pressurized side of your HVAC system – the duct runs that carry conditioned air from your air handler outward to every room in the house. In Johns Creek, supply duct cleaning typically runs $220 to $480 for a standard single-system home, completed in a single visit with a written price before any panel comes off. If you want a number before we arrive, call (470) 326-1926 and we’ll give it to you in writing.
Most duct cleaning services treat the whole system as one job, which is accurate enough for a basic cleaning estimate. But supply ducts and return ducts have different geometries, different contamination patterns, and different failure modes. A flexible supply run in a three-story Johns Creek home built in the early 2000s – common in the Shakerag and Medlock Bridge corridors – collects debris differently than a rigid sheet-metal return trunk. Knowing which side you’re cleaning, and why, changes how you clean it.
CleanRun has been doing this work since 2013. Every supply duct run we touch is photographed before we start and after we finish, delivered to you as a standard job record – not offered as an upgrade. That practice is written into our operating standard. For the full picture of what duct cleaning covers on both the supply and return sides, visit our Air Duct Cleaning in Johns Creek page.
What Supply Ducts Actually Do – and Why They Get Dirty
Your HVAC system runs in a loop. The return side pulls air from the living space back to the air handler; the supply side pushes treated air back out through registers in ceilings, floors, and walls. Every cubic foot of air that reaches your bedroom or living room traveled through a supply duct first.
Supply ducts run under positive pressure, meaning air is being pushed through them rather than pulled. That sounds like it should keep debris out, and largely it does – but it’s not airtight logic. Dust and particulates enter supply ducts during construction (a common finding in Johns Creek homes built between 2000 and 2015), through small gaps at register boots, through duct joints that have separated slightly over time, and during any renovation work that disturbs walls or ceilings. Once debris is inside a pressurized duct, it tends to pack into elbows and transitions rather than distribute evenly, which is why a Video Inspection often shows clean-looking straight runs and a significant build-up at the first 90-degree turn.
Our Rotobrush equipment uses a rotating brush head coupled with negative-pressure extraction – meaning we agitate the debris and immediately capture it, rather than pushing it through the system and into the room. That matters more on the supply side than people expect, because supply register boots sit directly above or below living spaces. Whatever comes loose has nowhere to go except into the air you’re breathing, unless you’re extracting it at the point of contact.
When You Need Supply Duct Cleaning
- Uneven airflow between rooms: If one bedroom in your Johns Creek home runs noticeably warmer or cooler than the others and your HVAC contractor has already ruled out damper issues, a partially blocked supply run is a likely cause. Debris accumulation at a transition point can reduce effective duct area by 30 to 40 percent without triggering any system alarm.
- Visible debris at supply registers: Dust rings around ceiling registers, or visible buildup on register louvers, indicate that debris inside the duct is being carried to the opening under air pressure. This is different from surface dust on a return grille – it means contamination is in the supply side of the system.
- Recent construction or renovation: Drywall dust, fiberglass particles, and construction debris enter duct systems during any work that opens walls or ceilings. In Johns Creek neighborhoods like Parsons Run and Bellmoore Park, renovation activity is frequent. Even with registers taped off, fine particulates find their way in.
- A home that hasn’t had duct cleaning in over 7 years: The EPA and NADCA both point to significant debris accumulation over multi-year periods in normal residential use. Supply runs in a four-bedroom Johns Creek home can accumulate a visible debris layer at elbows in as few as five to seven years under normal conditions.
- Mold or musty odor from supply registers specifically: Musty air coming from supply registers – rather than from the return side – suggests a moisture event inside the supply duct runs themselves. This is a separate issue from return-side contamination and requires targeted inspection of the supply duct interior.
- After a rodent or pest intrusion: Supply duct register boots, particularly in older single-story sections of Johns Creek homes, are common entry points for mice and insects. A single compromised boot can introduce debris and biological contamination into the pressurized side of the system, which then distributes it throughout the house.
BeforeAfterOur Supply Duct Cleaning Process
- Written scope and price before any work starts. Under Haven Standard Clause 1, you receive a written price that covers every supply duct run in scope before we remove a single register cover. No estimates that change when we open the access panel. The number you see before we start is the number on the invoice.
- Pre-cleaning camera inspection and photo documentation. Before any cleaning equipment enters the duct system, we photograph the interior of each supply run from the register boot. These images are date-stamped and delivered to you as part of your standard job record. You’ll see exactly what was there before we touched it – debris depth, location, and type. This is not a sales tactic; it’s a baseline record.
- System isolation and negative-pressure setup. We establish negative pressure at the air handler before any agitation begins. Negative-pressure extraction means a powerful vacuum draws air through the system toward a collection point, so that debris loosened during brushing is captured rather than redistributed. We use Nikro and Abatement Technologies equipment for this stage – both are trade-standard units that can handle the duct volumes in larger Johns Creek homes.
- Rotary brush cleaning of each supply run. A Rotobrush head – sized to the duct diameter – travels each supply run from the register boot toward the main trunk, agitating built-up debris from the duct walls. The brush and extraction work simultaneously, so debris doesn’t migrate. Elbows and transitions, which are the highest-accumulation points, get specific attention. Flexible duct sections require a modified approach to avoid liner damage.
- Register boot cleaning and register reinstallation. The register boot (the metal box that connects the duct run to the register opening in the wall or ceiling) is cleaned separately, as it tends to accumulate the highest concentration of debris. Registers are reinstalled and sealed at the boot to the manufacturer’s fit.
- Post-cleaning camera inspection and delivery of photo record. Every supply run is photographed again after cleaning, using the same angles as the pre-cleaning images. You receive both sets – before and after – so the result is documented rather than described. The 365-Day Done Right Promise is written onto your job record at this point: if the work isn’t right, we make it right, in writing, no manager approval required.
Supply Duct Cleaning Pricing in Johns Creek
Supply duct cleaning in Johns Creek costs $220 to $480 for a single-system home, based on the number of supply runs, the duct material (rigid sheet metal versus flexible duct), and access conditions. That range covers the full process described above – camera inspection, negative-pressure extraction, rotary brush cleaning, register boot cleaning, and the documented photo record – as part of our Air Duct Cleaning services. There are no add-on fees for the photo documentation or the 365-Day Done Right Promise; both are standard on every job.
| Home Size / System Type | Typical Supply Duct Count | Price Range |
|---|---|---|
| Single-story, 1,200-1,800 sq ft | 8-12 supply runs | $220 – $310 |
| Two-story, 2,000-3,200 sq ft | 14-22 supply runs | $300 – $400 |
| Two-system home, 3,500+ sq ft | 22-35+ supply runs | $380 – $480+ |
| Post-construction / heavy contamination | Varies | Quoted individually, in writing |
What moves a job toward the higher end of the range: flexible duct throughout (more careful handling required, more time per run), limited attic or crawl-space access, duct runs longer than 20 feet, or a two-system home where both air handlers and their associated supply networks need separate negative-pressure setups.
If you have a competitor’s written estimate, bring it. Under our Free Second Opinion policy, we put our number next to theirs in writing before any work starts. Call (470) 326-1926 and we’ll schedule an on-site assessment – the written price arrives before we open anything.
We don’t offer $79 specials or introductory rates. Every job is priced to cover the full process. If you’ve received a quote that number for a whole-house duct cleaning, the documented photo record, and the written guarantee described above, ask for it in writing before you book.
Johns Creek-Specific Conditions That Affect Supply Ducts
Johns Creek sits in a high-humidity corridor of north Fulton County. Summer dewpoints regularly reach the low 70s, and the transition between a conditioned interior and an unconditioned attic space creates condensation risk at supply duct connections – particularly where flexible duct meets a rigid trunk. Over time, this moisture can compromise the duct liner and create conditions where biological growth takes hold inside the supply run. We note any moisture-related findings in the pre-cleaning camera report before recommending a course of action.
Homes in the Medlock Bridge, Parsons Run, and Technology Park residential corridors tend to run flexible supply duct throughout the attic – a cost-effective original installation that performs well when intact but deteriorates at connection points over 15 to 20 years. We see flex duct separation at the register boot most frequently in homes built between 1998 and 2008. A separated connection isn’t just an air loss problem; it’s an entry point for attic particulates directly into the supply airstream.
Neighborhoods closer to Old Alabama Road, where two-story homes on established lots are more common, often have supply ducts running through interior wall cavities in addition to the attic. Wall-cavity supply runs require a different access strategy and are quoted separately when applicable.

FAQs – Supply Duct Cleaning in Johns Creek
How is supply duct cleaning different from return duct cleaning?
Supply duct cleaning addresses the pressurized runs that carry conditioned air from the air handler to each room; return duct cleaning addresses the side that pulls room air back to the air handler. They have different contamination patterns – supply runs tend to collect debris at elbows and transitions, while return runs collect at the grille and main trunk – and require the same core cleaning process but different entry points and pressurization setups. Most whole-house duct cleaning jobs include both sides. If you’re quoted for supply only, confirm whether the return trunk and main plenum are in scope. Call (470) 326-1926 and we’ll tell you exactly what’s included before any work starts.
