Abatement Technologies Air Duct Cleaning in Alpharetta: What to Know First
We clean duct systems in Alpharetta homes that move air through Abatement Technologies equipment, from HEPA filtration units to portable air scrubbers and the duct runs tied to them. A full system cleaning in Alpharetta typically costs between $450 and $900, and we quote that price in writing before any equipment gets touched. We’re an independent Abatement Technologies service provider, not a factory-authorized branch, which means we answer to you, not a manufacturer’s warranty clerk. This page is for Alpharetta homeowners who own Abatement Technologies air filtration or duct-connected equipment and want the whole system cleaned by a crew that understands it. Call (762) 769-7145 and Roy Castellanos or one of our techs will walk you through what you’re dealing with.
Key Takeaways:
- We clean the ductwork connected to Abatement Technologies filtration units, not just the unit itself.
- Every job gets a written price before work starts. The number on the quote is the number on the invoice.
- Our 365-Day Done Right Promise covers the work in writing. If it fails within a year, we return at no charge.
- We’re independent. We don’t push factory parts when a better aftermarket option exists, and we’ll tell you the difference.
How Abatement Technologies Products Fail – and How We Fix Them
In Alpharetta, we see a handful of recurring problems with Abatement Technologies equipment connected to residential ductwork. Here’s what actually breaks and what we do about it:
- Model HEPA 500 and HEPA 2000 filter loading. These units move serious air volume, and when the pre-filter or HEPA media loads up, the static pressure on the duct side climbs. That means dust no longer gets captured; it gets pushed past the unit and back into the supply runs. We clean the full duct path and replace or clean the pre-filters so the air handler isn’t fighting itself. Most Alpharetta homes we see with these units need this done every two to three years, more often if you’re near the wooded lots off Highway 9 where pollen load runs heavy in spring.
- Abatement Technologies Air Scrubber connected to return plenum. These pull air from the return side, and if your return ducts are packed with construction dust or pet hair, the scrubber’s intake screen clogs within months. Symptom: the unit runs louder than it should and you smell a musty note at the registers. We clean the return runs completely, not just the first few feet, and then verify airflow across the scrubber with a manometer.
- Gasketed filter housings leaking bypass air. On several Abatement Technologies cabinet designs, the gasket around the filter access door degrades in Alpharetta’s humidity and heat cycles. When that gasket fails, air bypasses the filter entirely. You’re paying to filter air that’s going around the filter. We replace the gasket with a proper closed-cell foam and test the cabinet seal after reassembly.
- Duct runs downstream of Abatement Technologies units collecting fine particulate. Because these units capture the big stuff upstream, the dust that accumulates in the supply ducts is the fine, sub-micron kind that settles into a hard film. That film doesn’t respond to a basic vacuum-and-brush job. We use a Nikro negative-air machine to pull the system under vacuum while our Rotobrush rotary brush agitates the duct walls, which is the difference between moving dust around and actually removing it.
- Return-side turbulence causing duct separation at takeoff collars. Abatement Technologies units often move more air than the original duct system was sized for. In older Alpharetta homes, especially two-story builds near Windward Parkway, that extra velocity works on the takeoff collars until they separate at the seams. We find the separation with a video inspection, reseal the collar with mastic, and reinforce the connection so it doesn’t fail again in twelve months.

Our Abatement Technologies Air Duct Cleaning Process
Every job follows the same sequence, because skipping steps is how you end up with clean-looking ducts that still blow dust. Here’s what happens when you call (762) 769-7145:
- 1
Scheduling and equipment walkthrough. When you call, a live person answers. We ask what Abatement Technologies equipment you have, where it’s located, and whether you’ve noticed anything off: musty smells, dust at registers, louder-than-normal operation. Then we set a window and arrive inside it.
- 2
System inspection and video camera pass. Our tech walks the system: register count, return locations, condition of the filter cabinet, duct material. We run a video inspection on the main trunk lines so you can see what’s actually in there before we touch it.
- 3
Written price, no surprises. You get the full number in writing before equipment leaves the truck. That price covers the whole system: supply runs, return runs, plenums, and the duct connections at your Abatement Technologies unit. It does not change at the door.
- 4
Negative-air cleaning with rotary brush agitation. We connect a Nikro HEPA-filtered negative air machine to pull the system under vacuum while the Rotobrush rotary brush runs through the ducts. The combo matters. Vacuum alone leaves the fine film on the duct walls; brush alone kicks dust loose and lets it resettle elsewhere. Together, they remove it.
- 5
Component check on your Abatement Technologies equipment. We inspect the filter cabinet, gaskets, and any connected air scrubber or filtration unit. If a gasket is cracked or a pre-filter is loaded, we’ll show you and give you a separate written price for that repair. No bundling, no pressure.
- 6
Final walkthrough and written guarantee. We walk you through the system after we’re done, show you the filter before-and-after, and hand you the 365-Day Done Right Promise in writing. That’s the whole job.

AfterWhat Abatement Technologies Air Duct Cleaning Costs in Alpharetta
Here are straight numbers for common Alpharetta scenarios involving Abatement Technologies equipment:
- Single-system residential, up to 10 ducts with one Abatement Technologies filtration unit: $450 to $650
- Larger two-story home with two independent systems, attic and basement units: $700 to $900
- System with heavily loaded HEPA unit requiring pre-filter replacement and gasket reseal: add $120 to $260, quoted separately in writing
- Commercial or light-warehouse space with multiple Abatement Technologies air scrubbers: $900 to $1,400, priced per system after walkthrough
What moves the price: how many registers and returns you have, how long the duct runs are, how packed the system is, and whether your Abatement Technologies unit needs component work beyond the duct cleaning itself. You’ll know the exact number before we start. Call (762) 769-7145 for a free estimate, and that estimate is a real number, not a range we sharpen up once the van is in your driveway.
Why Alpharetta Homeowners Call Hollis Air Duct Alpharetta for Abatement Technologies Work
We’ve been at this since 2004, and in that time we’ve cleaned a lot of duct systems across Alpharetta, including older two-story homes near Windward Parkway where decades of neglect had filled the returns with sediment that told a story all its own. Roy Castellanos completed his HVAC coursework at Los Angeles Trade-Technical College before relocating to Georgia, and he built this company around one standard: every register and return gets checked, not just the ones easy to reach. The Garrison Code is how we describe what our techs do on a job: arrive inside the window, put the price in writing, do the work by the book, and clean up before we leave. Every tech who walks into your home is background-checked and uniformed, so you know who you’re letting in before they arrive.
And if your Abatement Technologies unit fails within a year of us working on it, we come back and make it right at no charge. That includes a free second visit. It’s written down every time, not negotiated.
We also work on the other brands connected to these duct systems. If your home has a Lennox air handler feeding an Abatement Technologies filter cabinet, or a Trane furnace tied into an Abatement Technologies air scrubber, or a Carrier system with Abatement Technologies filters at the returns, we handle the whole setup. You don’t need to coordinate three different companies for one duct cleaning job. Call (762) 769-7145 and we’ll tell you straight what you’re looking at.
FAQs
Yes. Abatement Technologies units move air at higher static pressures than standard residential filtration, which changes how dust settles in the supply runs. The downstream ducts collect a fine film that a basic vacuum can’t lift, so we run a negative-air setup with rotary brush agitation instead. The cleaning method has to account for the equipment feeding those ducts.
No. Cleaning the ductwork connected to your Abatement Technologies unit does not affect the manufacturer’s warranty on the unit itself, and we don’t open sealed components on the equipment as part of a duct cleaning job. If the filter cabinet or intake needs service beyond what duct cleaning covers, we quote that separately in writing.
Every two to three years for most Alpharetta homes, but if you’re near the wooded lots off Highway 9 or run your system year-round, you may want to check at eighteen months. The pollen and humidity in this area load filters and ducts faster than drier climates. We’ll tell you at the end of the job whether your system looked like it was on schedule or behind it.
The system gets shut down while we clean. We need the blower off to pull the system under proper vacuum and keep the loosened debris from circulating through the house while we work. The unit gets powered down at the start and restored at the end.
Call (762) 769-7145 and a live person answers, day or night. We’re not going to tell you it’s a five-day wait without hearing what’s going on first. Once we know what Abatement Technologies equipment you have and what the symptom is, we’ll schedule a window and arrive inside it.
