AfterSupply Duct Cleaning in Sandy Springs, GA
Supply duct cleaning in Sandy Springs typically costs between $250 and $550 for a single HVAC system, with the work taking about 3 to 5 hours from setup to final cleanup. Supply ducts are the pathways that carry conditioned air from your furnace or air handler out to the vents in each room, and they collect dust, pet dander, and construction debris faster than most homeowners realize. At Hollis Air Duct Sandy Springs, our Air Duct Cleaning services use negative-air equipment and rotary brush systems, and every job gets a written price before we start. Call us at (229) 489-7780 and we’ll walk you through what your home needs.
This page covers what supply duct cleaning actually involves, the signs that yours need attention, how pricing works in Sandy Springs, and what our 365-Day Done Right Promise covers in writing. If you want a broader look at how supply ducts fit into your whole HVAC system, start with our guide to Air Duct Cleaning in Sandy Springs and then come back here for the supply-side specifics.
When You Need Supply Duct Cleaning
Most Sandy Springs homes need supply duct cleaning every 3 to 5 years, but certain conditions shorten that cycle. If any of these match what you’re seeing, it’s worth a closer look:
- Visible dust blowing from vents when the system kicks on. You’ll notice a fine layer of dust settling on furniture within a day or two of cleaning. That dust has passed through the blower and is being pushed directly into your living space through the supply ducts.
- You renovated recently. Homes in neighborhoods like Dunwoody Panhandle and Mount Vernon Woods collect drywall dust and sawdust in the supply runs during remodels, and that debris keeps circulating long after the contractor leaves.
- One or two rooms stay stuffy no matter where you set the thermostat. A partial blockage in a supply run reduces airflow to that branch, and the rooms at the end of that run end up warmer in summer and colder in winter.
- Your energy bills have crept up without a change in usage. Restriction in the supply ducts makes the blower work harder to move the same volume of air, and Georgia Power bills in Sandy Springs reflect that extra run time quickly.
- Anyone in the home has allergies that improve when you’re away. Pollen season in Sandy Springs runs long, and supply ducts retain pollen, mold spores, and dust mites that recirculate every time the AC or furnace runs.
- The home had a pest issue in the past. Rodents and insects leave droppings and nesting material in ductwork, and supply ducts are the path that carries those particles into every room.
If any of these sound familiar, the next step is a Video Inspection. We’ll tell you what we find and what it costs to fix before any equipment comes off the truck. Call (229) 489-7780 to schedule a look.
Our Supply Duct Cleaning Process
We follow the same sequence on every supply duct cleaning job in Sandy Springs, whether it’s a 1960s ranch near Hammond Park or a newer build off Roswell Road. The process is built around negative-air containment, which means the dust we dislodge gets pulled out of the home instead of floating into your living room.
- System inspection and written scope. We walk the system with you, open the access points, and assess the supply trunk and branch lines. Then we write the price down and hand it to you. That number does not change once the work begins.
- Protection and containment. We lay down corner guards and drop cloths at the furnace and around vent openings, and we seal off each supply register we’re not actively working on.
- Negative-air setup. We connect a HEPA-filtered negative-air machine to the supply plenum and seal the system. This puts the duct run under vacuum, so any dust we agitate is pulled toward the machine and captured, not released into your home.
- Agitation and extraction at each supply run. We use a rotary brush system with a whip line to scrub the interior walls of each supply branch and the main trunk. The loosened debris moves with the airstream toward the negative-air unit, where the filtration media catches it. For tighter branch lines, we use pneumatic tools to reach the full run from register to trunk.
- Register cleaning and sanitizing if needed. We remove each supply register, clean the visible interior surface of the boot, and wipe down the register itself before reinstalling.
- Final walkthrough and documentation. We walk the home with you, show you the access points, and confirm the system is producing proper airflow at each register. You get a record of what was done, and the work is covered under our 365-Day Done Right Promise in writing.
The equipment we run comes from Rotobrush and Nikro, the same brands commercial duct cleaning crews use on office buildings and medical facilities. We don’t use store-bought vacuums or rental equipment, because supply ducts in Sandy Springs homes need more pull than those tools can deliver.
Supply Duct Cleaning Pricing in Sandy Springs
If you’re wondering How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Sandy Springs, GA, supply duct cleaning runs between $250 and $550 for a single-system home. The range exists because square footage, number of supply runs, and how much debris is in the ducts all affect the labor and time involved. Here’s how the numbers break down:
| Service | Typical Price Range | What It Includes |
|---|---|---|
| Supply duct cleaning (single system, 1,500 sq ft or less) | $250 – $350 | Full supply trunk and branch cleaning, register removal and cleaning, negative-air containment |
| Supply duct cleaning (single system, 1,500 – 2,500 sq ft) | $350 – $450 | Same scope, with longer run times and additional branch lines |
| Supply duct cleaning (single system, 2,500 sq ft or larger) | $450 – $550 | Full scope on large homes, including long trunk runs common in older Sandy Springs builds |
| Combined supply and return duct cleaning | $400 – $700 | Both sides of the system cleaned in one appointment; most common full-system option |
| Vent/sanitizing fog application (optional) | $75 – $150 | Antimicrobial fog applied after cleaning, per EPA-registered product label instructions |
| Duct sealing (if leaks are found) | $400 – $800 | Sealing of accessible supply runs with mastic, quoted separately if needed |
What moves the price within those ranges? Three things. First, the number of supply runs: a split-level home off Peachtree Dunwoody Road with 10 or 12 registers takes longer than a ranch with 6. Second, the condition of the ducts: new construction dust is quick to clear, but decades of accumulation with pet hair mixed in takes more passes with the whip line. Third, whether the return side needs cleaning too, because the return ducts pull air back to the furnace and often carry as much debris as the supply side.
We quote one number, in writing, before the job starts. If we find something during the walkthrough that changes the scope, like crushed flex duct or a disconnected boot, we stop and show you first, and you approve the new number before we proceed. There’s no surprise line item at the end.
Every supply duct cleaning job is covered by our 365-Day Done Right Promise. That’s a written guarantee: if the work fails within a year, we come back and make it right at no charge, including a free second visit. We put that in writing on every invoice because that’s the standard we’ve run on since 2004.
FAQs – Supply Duct Cleaning
How much does supply duct cleaning cost in Sandy Springs?
Supply duct cleaning in Sandy Springs costs between $250 and $550 for a single-system home, depending on square footage, number of supply runs, and how much debris is in the ducts. Combined supply and return cleaning runs $400 to $700. Every quote is written down before work starts, and the price doesn’t move at the door. Call (229) 489-7780 for a free estimate on your home.
Is supply duct cleaning worth it, or is it just an upsell?
Supply duct cleaning is worth it when your ducts have visible dust buildup, post-renovation debris, or signs of rodent or pest contamination. The supply side carries all the air you breathe into every room, so what’s in those ducts lands in your furniture, your bedding, and your lungs. If your supply ducts are relatively clean, we’ll tell you that too, and we won’t sell you a cleaning you don’t need. A straight answer is part of how we price and run every job, and the 365-Day Done Right Promise covers the work in writing.
How long does supply duct cleaning take?
Supply duct cleaning takes between 3 and 5 hours for a single-system Sandy Springs home, including setup, the cleaning itself, and final cleanup. Larger homes with more branch runs or heavier debris take the longer end of that range. We arrive inside the quoted window, we leave the site clean, and we walk you through the system before we go.
Can you clean just the supply ducts and not the return ducts?
Yes, you can clean just the supply ducts, and for some homes that’s all that’s needed. However, the return side pulls air back to the furnace and often carries as much dust and debris as the supply side, so we’ll show you what we find in both during the walkthrough. You decide what gets cleaned, and the price for each scope is written down before any work begins. Call (229) 489-7780 and we’ll come assess your system for free.
Will supply duct cleaning help with dust in my home?
Supply duct cleaning reduces the amount of dust, pollen, and pet dander your system pushes into your living spaces. If the dust you see is mostly coming through the vents, cleaning the supply ducts addresses the source directly. If the dust is also coming through windows, doors, or settling from general household activity, you’ll see improvement but not a complete elimination, and we’ll be straight with you about that expectation before you spend anything.
What if something goes wrong after the cleaning?
If the work fails within a year, you call us and we come back at no charge, including the second visit itself. That’s the 365-Day Done Right Promise, and it’s written on every invoice we leave. We’ve been operating under The Garrison Standard since 2004, which means the price is in writing, the crew shows up inside the window, and the job is done by the book or it gets redone.
