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.
Supply Duct Cleaning in Alpharetta, GA
Supply duct cleaning focuses specifically on the duct runs that carry conditioned air from your HVAC system outward to every room in your home – the pressurized side of the network, where debris accumulates differently than it does on the return side. In Alpharetta, where new construction subdivisions like Windward, Crabapple, and Webb Bridge Park commonly use flex-duct systems installed during the building boom of the late 2000s and early 2010s, supply runs are frequent offenders: corrugated inner liners trap particulate at every bend, and the positive pressure that pushes air through the system also drives that particulate deeper into the duct before it has a chance to settle. Most homes we visit haven’t had the supply side cleaned independently – it usually gets lumped into our Air Duct Cleaning services, and that’s where shortcuts happen.
CleanRun Duct Repair & Cleaning has documented the inside of supply runs in Alpharetta homes since 2013, using Video Inspection to capture what homeowners can’t see. Every visit produces a before-and-after photo record of each duct run – not a general before-and-after of the system, but individual run documentation you can review room by room. That record is included on every job, at no additional cost, as a standard deliverable under the H.A.V.E.N. Standard. If you want a written price before a panel comes off, call (678) 679-7540 – our technicians quote in writing before any work starts, every time, with no exceptions.
Supply duct cleaning is a sub-service of our broader Air Duct Cleaning in Alpharetta offering. Some homes need both supply and return work done together; others have a supply-specific problem that can be addressed in a focused visit. The written quote will tell you which applies to your home before you commit to anything.
When You Need Supply Duct Cleaning
Supply ducts don’t announce themselves the way a clogged drain does. The signs are subtler – sometimes environmental, sometimes structural – and in Alpharetta’s climate they have a few patterns we see consistently from one neighborhood to the next.
- Uneven airflow room to room, especially on upper floors. Alpharetta’s two-story homes – common in Windward and the newer builds along Haynes Bridge Road – route supply runs through longer horizontal runs before reaching second-floor registers. When debris accumulates at elbows and transitions, the rooms at the end of those runs lose pressure first. If one bedroom is noticeably warmer or cooler than the rest of the house, a partially obstructed supply run is often the cause.
- Visible debris at supply registers during heating or cooling cycles. When the system kicks on and you see dust or dark particulate pushing out of the register grille, it’s coming from inside the supply run – not the filter. A filter catches what comes in on the return side; it doesn’t clean what’s already inside the supply duct.
- A home that was recently renovated or had drywall work done. Construction dust – fine gypsum and silica particles – is small enough to migrate into supply runs even when the system is off. In Alpharetta’s active renovation market, we regularly photograph runs in older homes that show a distinct white coating inside the first 8 to 10 feet of every supply run following a kitchen or bathroom remodel.
- Mold-like odor that appears only when the system is running. Alpharetta’s summer humidity creates condensation opportunities inside supply ducts, particularly near the plenum – the main distribution box that feeds the supply network. A musty smell that disappears when the HVAC shuts off is frequently traced to the supply side, not the unit itself.
- A system that hasn’t been cleaned since before 2018. The EPA guidance on duct cleaning doesn’t set a universal interval, but in Alpharetta’s pollen-heavy spring seasons, supply runs in homes with pets and children accumulate enough debris in five to seven years that airflow restriction becomes measurable. Our camera work in homes purchased between 2015 and 2020 typically shows 2 to 4 inches of settled particulate at the first bend past the plenum.
- Recent HVAC equipment replacement where the ductwork was left in place. A new air handler pushing air through a 12-year-old supply network is a very common scenario in Alpharetta’s older sections near downtown. The new equipment operates at higher efficiency ratings than the old system – sometimes a different static pressure profile – and that change in airflow dynamics can dislodge settled debris that had been stable for years.
Our Supply Duct Cleaning Process

Every job follows the same sequence. There’s no variation based on home size or job price – the documented process is the same whether we’re cleaning supply runs in a 1,400-square-foot townhome near North Point Mall or a 4,200-square-foot home in Windward. Here’s what happens from the time the technician arrives to the time the truck leaves.
- Pre-work camera inspection and documentation. Before any equipment is connected, the technician runs a camera through each supply run and photographs the interior. The camera footage shows the actual condition of the duct liner, the volume and type of debris at each transition point, and any visible mechanical damage to the duct wall. These images become the “before” portion of your photo record and establish what the job scope actually is – not what a salesperson estimated from the curb. If the camera shows something unexpected, like a collapsed flex run or visible microbial growth, you see the photo before any conversation about additional work begins.
- Written price confirmation before equipment is unpacked. The written quote is delivered based on what the camera found, the number of supply runs, and the linear footage involved. Under Haven Standard Clause 1, no work starts until the price is in writing and you’ve confirmed it. In practice this step takes about ten minutes and eliminates every pricing surprise that follows.
- Negative-pressure extraction setup. Negative-pressure extraction means we connect professional-grade vacuum equipment – typically Nikro or Abatement Technologies units – to the supply plenum and create a controlled suction environment inside the duct network before any agitation begins. This is the critical difference between real duct cleaning and shop-vac work: the vacuum runs continuously during agitation so that dislodged debris travels toward the collection unit, not toward your living space. The plenum is sealed at the air handler end to maintain consistent negative pressure throughout the run.
- Mechanical agitation, run by run. With negative pressure established, the technician works each supply run individually using rotary brushing equipment from Rotobrush – a brand built specifically for residential duct systems, with brush heads sized for the duct diameter in use. The technician moves from the register end toward the plenum, dislodging compacted debris from the duct liner while the vacuum continuously pulls the loosened material toward collection. Flex duct and sheet metal runs require different brush profiles; the technician selects the appropriate tool for each run type.
- Register and grille cleaning. Supply register grilles are removed, cleaned off-duct, and inspected for damaged dampers before being reinstalled. A restricted or bent damper inside a supply register creates a pressure imbalance that cleaning alone can’t fix; if one is found, you’re told in writing with a photo before any repair discussion begins.
- Post-work camera inspection and photo record delivery. The technician re-runs the camera through each supply run after the cleaning is complete and photographs the same reference points used in the pre-work inspection. The before-and-after images are compiled into your Documented Photo Record and delivered as a standard part of the job. You’re not asked to take the technician’s word for what changed – the camera shows it.

AfterSupply Duct Cleaning Pricing in Alpharetta
Supply duct cleaning in Alpharetta typically runs between $180 and $420 for a standard residential job, depending on several factors that the pre-work camera inspection makes concrete rather than estimated-see How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Alpharetta, GA for full pricing details. The written price you receive before work starts reflects the actual scope – not a range, not a starting-from number, and not a coupon that expands once the technician is inside the home.
| Scope | Typical Range |
|---|---|
| Single-story home, 8-12 supply runs, standard flex or sheet metal | $180 – $260 |
| Two-story home, 13-20 supply runs, including longer second-floor runs | $260 – $360 |
| Larger home with 21+ supply runs, multiple plenums, or post-renovation debris | $340 – $420+ |
| Supply duct cleaning combined with return duct cleaning (full system) | $320 – $640 |
Three factors move the price within those ranges. First, run count: a home in Alpharetta’s newer construction corridors near Avalon typically has more supply runs than an older ranch-style home near Wills Park, and each additional run adds time and labor. Second, duct type: corrugated flex duct – the type used in most Alpharetta construction after 1995 – requires more agitation passes than smooth sheet metal because debris embeds in the liner ridges. Third, debris load: the camera establishes this before the price is set. A home with 4 inches of compacted debris at every elbow takes longer to clean than one with light surface accumulation, and the price reflects that difference in writing.
What doesn’t affect the price after the fact: access difficulty, the technician’s time on-site, or anything else discovered after you’ve confirmed the written quote. Haven Standard Clause 1 means the written number is the number.
If you’ve received a written estimate from another company, CleanRun will put its own written number next to it at no cost. Call (678) 679-7540 and ask for the Free Second Opinion – the technician brings a competing quote and responds in writing, same visit.
FAQs – Supply Duct Cleaning

What’s the difference between supply duct cleaning and return duct cleaning?
Supply ducts carry conditioned air from your HVAC system to each room; return ducts pull room air back to the system to be filtered and reconditioned. They accumulate debris differently. Return ducts collect particulate that bypasses the filter – pet hair, fine dust, biological material – because they operate under negative pressure that draws air inward from the living space. Supply ducts collect debris that originated inside the system itself: dust that passed through the air handler before the filter caught it, plus construction residue and particulate that entered during installation or remodeling. In Alpharetta homes built between 2000 and 2015, we frequently find that the supply side carries a different debris profile than the return side – finer, more compacted, and concentrated near the plenum rather than at the register end. Both sides benefit from cleaning, but they require different agitation approaches and sometimes show different contamination types. The pre-work camera inspection tells us which side is the priority for your specific system. Call (678) 679-7540 and we’ll put the scope and price in writing after the camera has a look.
How long does supply duct cleaning take in a typical Alpharetta home?
A single-story Alpharetta home with 10 to 12 supply runs typically takes two to three hours from camera inspection to final photo documentation. A two-story home with 15 to 20 supply runs runs three to four hours. Those estimates assume standard flex duct in reasonable condition; a home with heavy post-renovation debris or a partially collapsed run will take longer, and the written quote will account for that before work starts. We don’t quote time-based pricing – the written price covers the job scope, not the clock – so there’s no financial incentive for the technician to work faster or slower than the job requires.
Can supply duct cleaning improve my HVAC system’s efficiency?
Yes, within specific limits. A supply run with significant debris accumulation at bends and transitions creates measurable static pressure resistance – the system has to work harder to push the same volume of air to each register. Removing that obstruction reduces resistance and allows the system to operate closer to its design specifications. In Alpharetta homes where we’ve measured airflow at second-floor registers before and after cleaning, it’s not unusual to see a 15 to 25 percent improvement in register velocity on runs that had heavy debris at the first elbow past the plenum. That said, cleaning is not a substitute for mechanical repairs, duct sealing, or equipment servicing – if the system has underlying issues, a clean duct won’t fix them, and we’ll tell you that in writing if the camera finds evidence of them. Our full home services page covers duct repair and sealing as a separate offering when the camera shows gaps or disconnected runs alongside the debris.
Is supply duct cleaning safe for homes with Aprilaire or Honeywell air filtration systems?
Yes, and in most cases those systems don’t require removal or bypass during supply duct cleaning. Aprilaire whole-home filtration units and Honeywell media filter housings are typically installed on the return side of the system, upstream of the air handler – meaning they’re not inside the supply network at all. The negative-pressure extraction setup we use during supply cleaning doesn’t create suction that would pull air backward through those units in a way that damages the media. The technician will confirm the filter housing location during the pre-work walkthrough and note it in the job scope. If your home has a filtration component installed in an atypical location, the camera inspection will show it before any equipment is connected.
