Or call (943) 271-6154NADCA, the duct cleaning trade association, puts a proper cleaning of an average-sized home in this band nationally, moving with duct type, system size, the number of systems and how dirty they are. Metro Atlanta price lists run lower for a single system.
NADCA's homeowner guidance tells people to steer clear of bargain-basement whole-house offers at this level, including the ones posted in neighborhood social media groups. A single system cleaned properly takes hours of labor and equipment that a figure like that cannot cover.

Every range below is what companies working in Marietta publish for that job, gathered from the numbered price pages under the table. It spans what several of them show, so the figures move with the specifics of the property and with who does the work. Nothing here is a quote, and no business has set a price on this page. A real number comes from whoever looks at the job.
| The job | Range seen | Billed as | What moves it |
|---|---|---|---|
| Whole-system duct cleaning, one HVAC system, supply and return runs plus the air handler | $250–$7001234 | per system | Metro Atlanta lists cluster from $250 to $550 a system. Confirm the returns, trunk lines and air handler are inside the number. |
| Two-system house, upstairs and main-floor units cleaned on one visit | $600–$1,50014 | per visit | Each air handler and its ducts are cleaned and priced as their own system, so two systems land near double. |
| Per-opening pricing, each supply register or return grille | $25–$75156 | per opening | Marietta figures sit at $30 to $39 a vent. Returns are larger and run toward the top. Count every opening before comparing. |
| Dryer vent cleaning, from the drum to the outside hood | $100–$249123 | per visit | A Marietta list charges $159 alongside duct work, $199 alone, and $8 a foot past twenty feet. Roof runs reach the top. |
| Air handler, blower wheel and coil cleaning added to a duct job | $60–$20016 | added | The blower wheel and coil usually hold more dirt than the ducts. Ask whether they are in the base price or extra. |
| Sanitizer or antimicrobial fogging of the ducts | $50–$15013 | added | Worth paying for only with a documented reason. The EPA registers no biocide for internally insulated ducts. |
| Bathroom exhaust fan cleaned on the same visit | $25–$7923 | added | One Marietta list adds it for $25 with other work; a standalone exhaust fan call starts higher. |

Duct cleaning prices around Marietta are built from a few parts, and once you know them a quote stops looking arbitrary. There is the base cleaning, usually priced per HVAC system. There is the size of that system, measured by the number of supply registers and return grilles more than by square footage. There are add-ons that are separate jobs, like a dryer vent, a coil, or a sanitizer. And there is the condition of what gets found when the panels come off.
Metro Atlanta companies post a single-system cleaning in a fairly tight band, and one Marietta company lists a flat per-unit price near the bottom of it. NADCA's national figure for an average-sized home runs higher. The gap is mostly about what is included. A real cleaning connects a negative-air machine to the trunk, works every supply and return run back toward it with brushes or air whips, cleans the air handler cabinet and blower, and seals the access holes it cut. If a quote does not say whether the returns, the trunk lines and the air handler are inside the number, ask before agreeing to anything.
A lot of two-story Marietta houses have one system for the upstairs, often with the air handler in the attic, and a second for the main floor in a basement, crawlspace or closet. Each is its own duct network and its own cleaning. Local price lists price them that way, which is why a two-system house lands near double a single system rather than at some small upcharge. Having both done on the same visit saves a trip, not a system.
Some companies price by the opening instead of the system. Marietta figures run about $30 to $39 a vent, and returns, which are larger and dirtier, cost more than supplies. Per-opening pricing is honest when every register and return is counted up front. The trouble is the flyer that promises the whole house for $99 or less. NADCA tells homeowners to avoid bargain-basement whole-house offers like that, because nobody can clean a system properly for that money. The usual pattern is a quick vacuum at the registers, then a list of extra charges once the crew is inside. If an offer looks like that, ask for the full scope and total in writing before anyone starts.
A dryer vent is not part of the heating and cooling system, so it is priced separately. Local lists put a standard run from the drum to the outside hood in a band that tops out near $250, with a lower figure when it is added to a duct cleaning. Long runs cost more: one Marietta list charges by the foot past twenty feet, and roof terminations and upstairs laundry rooms take longer than a short side-wall run.
In a humid Georgia summer the coil and blower wheel often hold more dirt than the ducts, so cleaning them is frequently the part that actually fixes a smell or weak airflow. Atlanta lists price an air handler and coil cleaning as a modest addition to a duct job. Sanitizer fogging is a different matter. It is worth paying for only with a documented reason, such as confirmed growth on hard metal ducts after the moisture source is fixed, and the EPA notes that no chemical biocide is registered for use inside internally insulated duct systems.
The EPA's guidance puts a cleaning at roughly $450 to $1,000 per heating and cooling system, and NADCA uses the same band for an average-sized home. Those national figures sit above the metro Atlanta single-system lists. A Marietta quote between the two is normal. A quote far below both deserves the question of what it leaves out.
How many systems, what is included in each, which add-ons are being done, and the total, all stated before anyone opens a panel. If repairs turn up, a separate price for each before it is done. That is the standard this site holds the work to, and the reason the table above exists.
Get the whole system in scope, the supply runs, the returns, the air handler and the coil, with the total settled before anything is opened. If there is water pooling under the air handler or a burning smell from the vents, switch the system off at the thermostat first and mention it when you call.
