We clean the ductwork, coils, and air handlers that move the air through Atlanta's offices, schools, and facilities — using NADCA source-removal methods and HEPA containment, scheduled around your building. Southeast Commercial Services is a licensed, insured contractor working commercial and industrial only.
Tell us about your building and system — we typically reply within the hour (Mon–Fri).
Every hour your HVAC system runs, it pulls air across coils and pushes it through duct that has been collecting dust, construction debris, pollen, and moisture since the last time anyone looked inside. Left alone, that buildup becomes the thing your system recirculates to every occupied space — and the restriction your fans have to fight against. Southeast Commercial Services cleans it out at the source so your air and your equipment both breathe easier.
For over 30 years we've served Atlanta's offices, schools, healthcare buildings, and industrial facilities for the facility managers and operations directors who answer for indoor air quality, energy cost, and inspection readiness. Duct cleaning is one line in a full commercial facility program — so it can be bundled with HVAC service, painting, or repairs under one contract.
Bringing a crew into your air-handling systems is a due-diligence decision. Here's what clears our name through procurement before we ever open an access panel.
We follow the association's source-removal principle — extracting contaminants under negative pressure, not fogging them.
Established in 1991, with 30+ years servicing commercial and industrial facilities across the metro.
Southeast Commercial Services of Georgia LLC — a registered, licensed contractor you can verify.
General liability and workers' comp in place; we issue a certificate naming your property on request.
The system is put under negative pressure so dislodged debris flows into collection, never back into your spaces.
Captured contaminants pass through HEPA filtration so fine particulate leaves the building instead of recirculating.
Supply and return runs, grilles and diffusers, coils, blower, and drain pan — the whole air path, not just the trunk.
We don't clean home systems. Every crew, method, and schedule is built for occupied business facilities.
We inspect before and confirm after, so cleaning is a documented result rather than a claim.
A single project lead owns your job start to finish — no chasing a rotating cast of subs.
A neglected HVAC system charges you in three currencies at once — the air your people breathe, the power bill your system runs up, and the risk that shows up on an inspection.
Ductwork is the distribution network for everything airborne in your building. When it's loaded with dust, pollen, and biological growth, the HVAC system doesn't filter that out — it delivers it to every desk, classroom, and patient room on the loop. Cleaning at the source pulls that load out of the airstream, which is what lowers:
Debris on coils and in the blower assembly is friction. Your equipment has to work harder to move the same air across restricted coils, and that shows up on the utility bill and in shortened equipment life. Restoring the air path helps:
In many commercial and institutional settings, indoor air quality isn't optional — it's something you have to be able to demonstrate. A documented cleaning gives you a record you can show. It supports:
Duct cleaning goes wrong in ways that land on the facility manager's desk, not the technician's. A crew that blows debris into occupied space instead of containing it. A "cleaning" that fogs a chemical through the system and calls it done. A one-truck operation that opens the ductwork, gets overwhelmed by the scale of a commercial run, and leaves the coils untouched. Those are the outcomes that turn a maintenance line item into a complaint thread.
We built our commercial operation to take those risks off your plate. That means negative-air containment and HEPA collection so contaminants leave the building, source removal instead of chemical cover-up, insured crews who show up on the schedule they promised, and a single project lead who answers when you call. You get one contract, one accountable team, and a system that's genuinely cleaner when we leave.
Work is phased zone by zone and unit by unit so the building stays open, staffed, and productive throughout the job.
Licensed and multi-million-dollar insured, with a certificate of insurance issued to your property on request.
No rotating subs. One project lead runs your job from inspection to post-verification and stands behind the result.
Source removal is a method, not a shortcut. Every job follows the same disciplined sequence — so the contaminants come out of the system instead of getting stirred back into your building.
Truck- and portable-mount negative-air machines put the system under vacuum and route every dislodged particle through HEPA filtration before it can re-enter your space.

Rotary brushes, air whips, and compressed-air tools physically break contaminants loose from duct walls so the vacuum can carry them out — the core of source removal.

We clean the evaporator coil, blower, and drain pan inside the air handler — where restriction and biological growth actually collect — not just the visible duct.
HVAC Systems →We walk the system, camera-inspect representative runs, and assess coils and air handlers to define exactly what needs cleaning.
Access points are established and the system is put under negative pressure so all dislodged debris flows toward collection, not your occupied space.
Rotary brushes, air whips, and compressed-air tools break contaminants loose from the interior duct surfaces throughout the runs.
The negative-air system extracts the loosened material through HEPA filtration, so fine particulate leaves the building rather than recirculating.
Evaporator coils, blower assembly, and drain pan are cleaned to restore airflow and remove the growth points inside the air handler.
Where a system shows microbial growth, an EPA-registered antimicrobial can be applied after cleaning — as a finish to source removal, never a substitute.
We re-inspect the cleaned system, confirm the result, restore access panels, and document the work so you have a record on file.
A commercial system can't be cleaned with a shop vac and a wand. The method is defined by the standard we follow and the equipment that makes source removal possible.
Our work follows the National Air Duct Cleaners Association's source-removal principle — physically extracting contaminants under negative pressure rather than masking them, which is the benchmark specifiers ask for.
Truck-mount and portable negative-air units place the ductwork under vacuum, creating the pressure differential that pulls every dislodged particle toward collection instead of into your building.
Collected air is filtered through HEPA media, capturing fine particulate down to the sizes that matter for indoor air quality — so what comes out of the duct doesn't go back into the room.
Mechanical agitation tools sized to the duct dislodge caked debris from interior surfaces that vacuum alone would leave behind — the difference between a real clean and a surface pass.
Duct-inspection cameras let us see conditions before we start and confirm the result after, turning "we cleaned it" into a documented before-and-after.
Coil tools and cleaners restore heat-exchange surfaces and airflow inside the air handler — the part of the system most responsible for lost efficiency when it's fouled.
Source-removal cleaning isn't cosmetic. When the ductwork, coils, and air handler are genuinely clean, the building runs better on every axis that matters to a facility manager.
Pulling dust, allergens, and biological growth out of the airstream lowers recirculated particulate and the complaints that come with it.
Clean coils and clear ducts let the system move air with less resistance — easing the load your fans and motors carry.
Removing the moisture-fed growth in humid runs takes out the musty odors and microbial sources people notice first.
An HVAC unit that isn't fighting restriction runs cooler and cleaner — and equipment that works less lasts longer.
Every building type carries its own air-quality demands, occupancy patterns, and scheduling constraints. These are the commercial and industrial facilities we're built to service across metro Atlanta.
A real proposal is a document, not a flat per-vent price. When you compare bids, these are the six things that separate a professional commercial scope from a residential-style number.
We count and identify what actually has to be cleaned — the number of air-handling units, the supply and return trunk and branch runs, the grilles and diffusers, and the coils inside each unit. Inventorying the system up front is what lets you compare bidders on equal terms instead of guessing whether "the whole building" means the same scope to everyone.
The scope states how the system is isolated and put under negative pressure so contaminants flow to collection, not into occupied space. On working buildings it also covers how adjacent areas are protected. This is the line that keeps a cleaning from becoming a dust event your tenants complain about.
We name the method — NADCA-based source removal with mechanical agitation and HEPA-filtered extraction — rather than leaving "cleaning" undefined. Naming the standard holds us to it and tells you the debris is being removed from the building, not fogged over or blown downstream.
The scope spells out exactly what's covered: duct runs, grilles, registers and diffusers, and the air-handler internals — coils, blower, and drain pan. Components are where the real efficiency and air-quality gains live, so they're listed explicitly rather than assumed or quietly excluded.
We map the work to your calendar: which units and zones are cleaned in what order, what happens during business hours versus off-peak windows, and how long each phase takes. A phased plan is the difference between a cleaning that quietly happens around your operation and one that shuts down a wing you needed open.
The scope defines how the job ends: post-cleaning inspection, restored access, and documentation of the work performed. A defined closeout gives you a verifiable record for your maintenance file and inspection readiness — not just a crew that packs up and drives away.
Most of the buildings we service can't simply shut down for a duct cleaning — staff still report, tenants still operate, classes and appointments still run. So we plan the work around your operation rather than through it. We clean one air-handling unit or one zone at a time, isolating it under negative-air containment while the rest of the system keeps serving the spaces you need occupied.
Our office hours run Monday through Friday, and we phase and schedule the work to fit the rhythm of your facility — concentrating the noisier tasks in your lowest-traffic windows and, where a space has to stay open during business hours, running early mornings, evenings, or weekends. Negative-air containment and HEPA collection keep dislodged debris out of occupied areas, and we protect adjacent finishes and equipment while crews are on site.
The goal is simple: you get a genuinely cleaner HVAC system and better indoor air, and your operation barely notices the crew was there.
From two Atlanta-area offices, Southeast Commercial Services cleans the HVAC systems of commercial and industrial buildings throughout Fulton, DeKalb, Gwinnett, Cobb, and Cherokee counties — from Midtown office towers to Gwinnett distribution centers.
Planning a cleaning? Tell us the building type, rough square footage, and how many HVAC units you run, and we'll schedule an inspection and return a written scope you can act on.
Working from offices in Atlanta and Decatur, our crews reach commercial and industrial sites across the region's major corridors and surrounding counties.
We follow the metro's freight and office arteries — the I-75, I-285, and I-85 corridors — to reach office towers, schools, and distribution facilities throughout the region. Coverage spans Fulton, Cobb, Gwinnett, DeKalb, and Cherokee counties, from intown high-rises to the industrial belts on the perimeter.
If your building sits inside the greater Atlanta area, we can most likely service it. Not sure whether you're in range? Call (404) 924-7071 and we'll confirm coverage and set an inspection.
Duct cleaning often pairs with the rest of the HVAC and facility work a commercial building needs — handled by the same accountable team on the same schedule.
Cleaning you can't see is cleaning you have to be able to trust. We stand behind the method, document the result, and give you a straight answer about what your system actually needs.
Our work is guaranteed against being done to less than the source-removal standard we quote. If a cleaned system doesn't meet the scope, we make it right — that's the point of a documented method.
We inspect before and confirm after, and hand you documentation of the work performed — a record for your maintenance file and inspection readiness, not just a verbal all-clear.
We'll tell you straight when a system genuinely needs cleaning and when it doesn't — so your maintenance budget is planned on the building's real condition, not a sales calendar.
Commercial duct cleaning is the source removal of dust, debris, and biological growth from a building's HVAC ductwork, coils, and air handlers — using negative-air containment and HEPA collection to improve indoor air quality and system efficiency. In Atlanta, it's provided by Southeast Commercial Services, a licensed, insured contractor using NADCA-based methods, commercial and industrial only.
Unlike residential duct cleaning, commercial work is scheduled around your operating hours, covers multiple air-handling units and long trunk runs, and is verified after cleaning. Southeast has served Atlanta facilities for over 30 years and sequences the job to keep your building occupied and running while the ductwork is cleaned.
Straight answers to what Atlanta facility managers ask before signing a duct cleaning contractor.
For most commercial buildings, a cleaning every three to five years is a sensible baseline, but the right interval depends on the building. High-occupancy offices, schools, and healthcare spaces, dusty industrial environments, and any system recovering from renovation, water intrusion, or mold usually need attention sooner. We inspect the system first and recommend an interval based on what the ductwork and coils actually show — not a fixed calendar.
When ducts, coils, and the air handler are genuinely dirty, source-removal cleaning reduces the dust, debris, and biological growth that the HVAC system would otherwise recirculate through occupied spaces. Pulling that load out of the airstream lowers airborne particulates and the allergens and odors that ride with them. We use NADCA-based source-removal methods and HEPA-filtered collection so the contaminants leave the building instead of being stirred back into it.
It depends on the size of the building, the number of air-handling units, and how the system is laid out. A single-tenant office suite may be a one-day job, while a multi-story building or a campus with several units is scheduled over several days or in phases. After we inspect the system, you get a written scope with a realistic timeline before any work begins.
We clean the full air path, not only the duct runs. That includes supply and return trunks and branches, grilles, registers, and diffusers, and the components inside the air handler — evaporator coils, blower assembly, and drain pan. Coils and the blower are where much of the restriction and biological growth collects, so cleaning them is what restores airflow and efficiency, not just appearance.
NADCA is the National Air Duct Cleaners Association, which publishes the industry standard for HVAC system cleaning. The core principle is source removal — physically dislodging and extracting contaminants under negative pressure rather than masking them with chemicals or fogging. We follow NADCA-based source-removal methods so the work is verifiable and the system is genuinely cleaned, which is the standard facility managers and specifiers look for.
We plan the work around your building rather than through it. Crews section off one zone or air-handling unit at a time, keep negative-air containment and HEPA collection running so dust stays contained, and can work early mornings, evenings, or weekends when a space has to stay occupied during business hours. Our operations run Monday through Friday, and we sequence the job so the areas you need stay usable throughout.
Tell us the building type, rough square footage, and how many HVAC units you run. A Southeast Commercial Services team member will follow up to schedule an inspection — typically within the hour, Monday–Friday.
