Frequently Asked Questions - Air Duct Cleaning in Sandy Springs, GA
Straight answers to the questions Sandy Springs homeowners ask us most, from real pricing to how the work actually gets done. Roy Castellanos leads our local team, and we follow The Garrison Code on every job.
Pricing & Cost FAQs
A whole-system air duct cleaning in Sandy Springs typically runs between $350 and $650 for an average single-family home, depending on home size, number of vents, and how long it's been since the last cleaning. That's the honest range for a full cleaning of the supply and return ducts, the trunk lines, and the air handler. You'll get a written price before any work starts, so there's no number that moves once we're at your door. Call (229) 489-7780 and we'll give you a firm quote based on your actual home, not a guess.
A $99 whole-house duct cleaning quote is almost always a bait-and-switch. The low price gets a crew to your driveway, then the invoice grows with add-ons for returns, sanitizing, or "mold treatment" that should have been included. Our price covers the full system, every vent, every return, the trunk lines, and the air handler, agreed in writing before we start. If a quote seems too cheap to pay for the time and equipment a real cleaning takes, it usually is.
We price per system, not per vent. You get one flat price for the whole duct system, clearly spelled out, before any work begins. Per-vent pricing is how some companies advertise small numbers that multiply into big invoices. Our written estimate tells you exactly what you'll pay for the complete job. That's The Garrison Code: price in writing before any work starts.
A full cleaning covers every supply and return duct, all vent covers, the main trunk lines, the plenum, and the air handler cabinet. We also inspect the system as we go and point out anything that needs attention. You'll know the final number before we start, and nothing gets added at the door. If your system needs something outside the quote, we'll show you and get your okay first.
You get a written price for your exact system before any work starts, not a vague estimate that drifts upward. We'll ask a few questions about your home, the number of vents, and the last time the ducts were cleaned, then give you a firm number. If we find something unexpected once we're inside the system, we stop and talk to you before doing anything beyond the agreed scope.
Service & Process FAQs
We connect a high-powered vacuum to your duct system to create negative pressure, then loosen the debris with rotating brushes and air whips, working vent by vent until everything is pulled out. We cover every supply and return, the trunk lines, and the air handler cabinet. Afterward, we leave the site clean and squared away, per The Garrison Code. The whole job usually takes between three and five hours for a typical Sandy Springs home.
Most single-family homes in Sandy Springs take three to five hours from start to finish. Larger homes or systems that haven't been cleaned in a decade or more can stretch toward a full workday. We'll give you a realistic time window when we schedule, and we arrive inside the window we gave you. That's a promise we put in writing and stand behind for a full year.
Most Sandy Springs homes need air duct cleaning every three to five years. Homes with pets, recent renovation work, smokers, or allergy sufferers often need it more often, sometimes every two years. If you've never had your ducts cleaned and the home is older than ten years, start now and then move to the three-to-five-year cycle. We'll tell you honestly if your system needs it sooner based on what we find.
You get before-and-after photos of your own ducts, showing the same vents before and after we clean them. You can see the difference with your own eyes, not take our word for it. We also walk you through what we found and what we did before we pack up. That's how a homeowner knows the job was real: photographic proof of your own system, not a stock photo.
Yes, dryer vent cleaning is part of what we do, and it matters more than most people realize. Lint buildup is a fire hazard, and Sandy Springs homes with long vent runs or second-floor laundry rooms are especially prone to it. We clean the full dryer vent run from the dryer to the outside exhaust. If you haven't had yours done in the last two years, ask about adding it when you call (229) 489-7780.
Yes. A duct cleaning that skips the air handler leaves the source of much of the dust in place. We clean the air handler cabinet, the blower, and the accessible evaporator coil as part of the system. That's what makes the cleaning hold up: the air moving through your freshly cleaned ducts isn't picking up new debris from the source.
It often does, especially in Sandy Springs where spring pollen season runs long and heavy. Your ducts collect pollen, dust, pet dander, and whatever else floats through a Georgia home, then recirculate it every time the system runs. A thorough cleaning removes that reservoir, which means less of it in your breathing air. It's not a cure for allergies, but it removes a real source of irritants.
Brands & Parts FAQs
We use professional-grade negative-air machines and agitation tools from manufacturers like Rotobrush and Abatement Technologies. These are the standard tools of the trade, built for full-system cleaning, not the small shop vacs that some low-price operators use. The right equipment is the difference between loosening and removing debris versus just stirring it around. We bring the gear that does the job by the book, the first time.
Aprilaire makes quality whole-home filtration options, and they're a good fit for many Sandy Springs homes, especially during pollen season. A good filter helps keep your freshly cleaned ducts cleaner longer. We'll talk through your options based on your system and your household's needs, and we'll never push a product you don't need. The goal is cleaner air, from the vents on out.
We focus on getting your duct system clean and keeping it that way. We can talk through filtration options that work with your existing HVAC setup, including brands like Aprilaire, and point you to what makes sense for your home and budget. But our core job is the ducts themselves, done right and guaranteed in writing for a full year.
We don't push chemical sanitizers as an upsell. The mechanical cleaning does the real work: removing the dust, debris, and contaminants rather than treating them. If a homeowner specifically wants sanitizing, we'll discuss it honestly, including what it can and can't do. But the foundation of the job is always the physical removal of what's built up in your system.
