AfterAir Duct Cleaning Near You in Alpharetta, GA
Air Duct Cleaning services in Alpharetta typically cost between $285 and $490 for a standard single-system home, and most jobs are completed in 3 to 5 hours. We’re Hollis Air Duct Alpharetta, and we’re based right here in the area with crews on the road daily. If your vents are pushing dust onto furniture or you can’t remember the last time the ducts were touched, call (762) 769-7145 and we’ll get you a written quote before any work starts.
We serve homeowners across north Fulton and south Forsyth counties, including Alpharetta, Cumming, Suwanee, Canton, Druid Hills, Fair Oaks, Roswell, and Milton. Our home base keeps us close enough to show up inside the promised window, not “sometime between 8 and 5.”
Fast, Local Air Duct Cleaning
Same-day and next-day appointments are available for most of our service area, and after-hours calls are answered by a live person, not a voicemail tree. When pollen season hits in April and May, or when the humidity builds up through July and August, we run extra crews because we know Alpharetta homes take on more particulate matter during those stretches. A typical Residential Duct Cleaning job here, anywhere from 1,800 to 3,500 square feet, takes about half a day from setup to final walkthrough.
We use the negative-air method paired with rotary brush agitation. Put simply, the rotary brush knocks debris loose from the duct walls while a negative-air machine keeps the whole system under vacuum so nothing escapes back into your living room. That matters in a place like Alpharetta, where a lot of homes run the HVAC hard from June through September and the ducts build up more than just dust – think drywall fines from remodels, pet dander, and the fine red clay dust that tracks in from driveways and yards around Crabapple and Windward.
You’ll know who’s walking into your home before they arrive. Every technician is background-checked and arrives in uniform. The price is written down before any work begins, and it does not move at the door. That’s The Garrison Standard, and Roy Castellanos holds every crew to it on every job.
Areas We Cover
Our crews work throughout north Fulton and south Forsyth counties. If you’re in Alpharetta, we’re likely 20 minutes or less from your driveway. We also run regular routes through:
- Cumming – including the neighborhoods off Bethelview Road and around Sawnee Mountain
- Suwanee – from the Town Center area out toward the Chattahoochee River
- Roswell – covering Historic Roswell, East Cobb border streets, and the corridor along Highway 9
- Milton – especially along Freemanville Road and the larger estate lots where duct runs tend to be longer
- Canton – including the BridgeMill and Harmony on the Lakes communities
- Fair Oaks and Druid Hills – the pockets just inside the Cobb County line where a lot of callers assume they’re too far out. You’re not.
If you’re on the edge of our normal service area, call anyway. The worst we’ll tell you is the drive adds an hour, and the quote still comes in writing before you commit to anything.
What Air Duct Cleaning Actually Costs in Alpharetta
The most common question we get is about price, so here are straight numbers for this market. Alpharetta pricing runs slightly higher than some surrounding areas because of lot sizes, second-story duct runs, and the age of many systems in neighborhoods built in the 1990s and early 2000s. That said, the range below holds for most homes we see.
| Home Size | Typical Price Range | Time on Site |
|---|---|---|
| Up to 1,500 sq ft (condo, townhome) | $225 – $320 | 2 – 3 hours |
| 1,500 – 2,500 sq ft | $285 – $410 | 3 – 4 hours |
| 2,500 – 3,500 sq ft | $370 – $490 | 4 – 5 hours |
| 3,500+ sq ft or two systems | $480 – $650 | 5 – 7 hours |
A few things that change the number on your written quote:
- Adding dryer vent cleaning runs $75 to $125 on most jobs, and we recommend it while we’re already set up.
- Duct sealing with mastic runs $350 to $600 depending on access. Mastic is a paste applied at the joints and seams where ducts meet; it hardens into a permanent seal that stops conditioned air from leaking into the attic or crawlspace. It’s not tape.
- If your system has never been cleaned and you have pets, expect the higher end of the range. Pet dander compacts into the duct lining and takes longer to remove properly.
- Homes with flex duct in the attic, common in Alpharetta subdivisions built after 1995, sometimes need additional access panels cut. We price that in the written estimate, not as a surprise add-on.
Every job gets a written price before any work starts. That’s not a sales tactic; it’s The Garrison Code. Roy Castellanos and the whole crew at Hollis Air Duct Alpharetta operate on a simple rule: the number on the paper is the number on the invoice.
What the 365-Day Done Right Promise Covers
Here’s what it says, in plain terms: if the work we do fails within one year, we come back and make it right at no charge. That includes a free second visit, not a pro-rated credit or a “we’ll take another look” promise. If we cleaned your ducts and six months later you’re seeing the same buildup you called us about, we return, we re-clean, and it costs you nothing.
Every repair and every cleaning carries this warranty in writing on the job paperwork. We put it there because a guarantee that lives only in a sales pitch isn’t a guarantee. You should know exactly what’s covered, for how long, and what happens if the work doesn’t hold up. Most companies in the duct cleaning trade won’t put that on paper. We do, every time.
How the Cleaning Process Works
If you’re comparing companies, here’s what you should expect a proper job to look like, and what we do at every home.
The Equipment
We run Rotobrush rotary brush systems paired with Nikro negative-air machines. The rotary brush is exactly what it sounds like: a spinning brush that travels through the duct and knocks debris off the walls. The negative-air machine connects at the other end and pulls the dislodged material out before it can settle anywhere else. This is the same combination Commercial Duct Cleaning crews use on office buildings and medical facilities. We don’t use hardware-store gear or a shop vac and call it done.
For filtration, we carry products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. If your system has a media cabinet or you’re considering an upgrade, we’ll tell you what’s actually worth spending money on and what isn’t.
The Walkthrough
Every job starts with a look at the system. We check the return and supply registers, the filter, the blower compartment, and the condition of the ducts themselves. If we find cracked ductwork, disconnected runs, or leaks at the plenum, we’ll show you photos of the issue and explain what it means for your air and your power bill. You decide what you want us to do. We won’t pressure you into an upsell.
The Work
We protect the floors around each register, run the equipment through the full duct system for a Full System Cleaning, and finish by cleaning the registers and grilles so everything is left the way it should be. The site is left clean. That’s part of The Garrison Code, not a courtesy.
Signs Your Ducts Need Cleaning in Alpharetta
Most homeowners call us when one of these shows up:
- Dust returns to furniture surfaces within a day or two of cleaning
- One or more rooms stay noticeably warmer or colder than the rest of the house, even after filter changes
- You can see dust or debris at the register grilles when you shine a flashlight in
- The dryer takes more than one full cycle to dry a load, which usually points to a clogged vent rather than a failing dryer
- Pollen or dust lines appear around the door and window frames during March, April, and May
- You moved into a home that had construction or heavy renovation work done before you bought it
If you’re seeing any of these, the ducts are the first place to check. Call (762) 769-7145 and tell us what you’re seeing. We’ll tell you straight whether cleaning will fix it or if something else is going on.
Why Alpharetta Homes Need Duct Cleaning More Often
There are a few reasons this market keeps our crews busier than most.
First, the clay soil. Alpharetta sits on Georgia red clay, and when it dries out in late summer, fine dust gets airborne and finds its way into homes through windows, doors, and on shoes. That dust eventually makes it into the return air stream and settles in the ducts. Second, the pollen. If you’ve lived here through a spring, you know the yellow film on the cars. That same pollen pulls into the HVAC system every time the air handler runs. Third, the humidity. Long, wet summers mean the interior of uninsulated or poorly sealed ducts can develop film that traps debris more than dry climates do.
The result is that a five-year schedule, which works fine in drier parts of the country, often looks more like two to three years here for households with pets, allergies, or kids tracking in from the yard. We’ll never push you into a cleaning you don’t need. But if we’re in your ducts and find solid evidence of buildup, we’ll show you before and after photos and let the condition speak for itself.
Duct Sealing and Why It Matters in Alpharetta
Duct sealing is the less glamorous half of the air quality equation, and it’s the one that actually saves money year-round. In a typical Alpharetta home, the ductwork runs through an unconditioned attic that hits 120 to 130 degrees in July and August. If the seams and joints on those ducts aren’t sealed properly, a portion of the air your system paid to cool leaks straight into the attic. You’re paying to air-condition insulation.
We seal ducts with mastic, a heavy paste that’s brushed over the seams and joints. It dries hard and holds. It doesn’t peel like tape, and it’s rated for the temperature swings our attics see. If your family rooms upstairs never seem to cool as well as the downstairs, duct leaks are often the reason.
Who Answers Your Call and Shows Up at Your Door
Phones are answered by a live person 24 hours a day, 7 days a week. Not an answering service that takes a message and hopes someone gets back to you Monday. You’ll talk to a person who knows the scheduling calendar and can tell you whether we have a same-day opening or whether tomorrow morning works better.
The technicians who arrive are background-checked and uniformed. You’ll know the name of the person coming to your door before they ring the bell. Every member of the crew is expected to follow The Garrison Code, which means four things in practice: arrive inside the window we gave you, put the price in writing before work starts, do the job by the book, and leave the site cleaner than they found it. Roy Castellanos signs off on that code for every job, and he’s the one you can ask for if anything falls short.
