Air Duct Cleaning in South Fulton
Ducts collect dust, pull loose in hot attics and leak cooled air before it reaches a room. We look first, tell you whether cleaning will change anything, then clean, seal or repair across South Fulton and nearby towns.
Dusty, clogged vents?
Until it is fixed: Leave registers and attic duct joints alone; tugging on flex duct pulls it loose and makes leaks worse.
Does cleaning air ducts really make a difference?
Sometimes. Duct cleaning has never been proven to stop health issues (EPA). It is needed in 3 cases. Large amounts of mold growth on the inside of the metal ducting. Vermin in the ducting. Or excessive amounts of dust/debris blocking the ducting. The main issue in South Fulton will be leaks. Many ducts will be in the attic or crawlspace. Over a long humid summer loose joints suck in hot and damp air from the attic. In Sandtown there are plenty of homes pre-1980. The ducts have had decades to sag. Sealing the ducts will make a difference. Georgia Power has a HEIP rebate program offering 50% of the cost of repairing and sealing ducts, up to a cap.
What a duct visit includes
Dirty vents are why you called. We also check the filter, the blower, the return and every duct run we can reach.

A look inside first
A camera or light inside the trunk and returns shows whether there's real buildup worth paying to remove.
Brush and vacuum
Rotary brushes knock debris loose while the vacuum hose pulls it out, so the dust leaves the house.
Coil and blower check
A dirty indoor coil or blower wheel can coat freshly cleaned ducts with dust again, so both get a look.
Seams and connections
ENERGY STAR says typical ducts lose about 20 to 30 percent of their air. We find where yours leak.
Airflow at each register
Every room gets steady airflow again, and the return pulls without whistling, rattling or a sucking door.
Filter and drain check
The filter is checked or replaced, access panels close tight, and the condensate drain is flowing clear.
Flex duct or sheet metal: which does your home have?
Flex duct is round and soft, with a plastic jacket over insulation. Sheet metal is rigid and rings when you tap it. Flex tears under a stiff brush, so the method changes.
| Duct detail | Flex duct | Sheet-metal duct |
|---|---|---|
| What it is | A wire coil inside insulation and a plastic outer jacket. | Rigid galvanized steel, round or rectangular, often wrapped in insulation. |
| Where it sits | Branch runs from the main trunk out to each room's register. | Main trunks off the air handler, plus some older branch runs. |
| Usually found in | Attic and crawlspace branch runs in many South Fulton homes. | Main trunks, and branch runs in older homes. |
| What failure looks like | Kinked, crushed or torn runs, and one room barely getting air. | Separated joints, rust spots, or old tape peeling off seams. |
| What the repair needs | Gentle cleaning, or a new section when the jacket is torn. | Brushing, then mastic or metal tape on leaky joints, never duct tape. |
What are the warning signs my air ducts need cleaning?
- Mold growth you can actually see inside a metal duct or at a register.
- Droppings, nesting material or chewed insulation from mice or other vermin.
- Dust puffing out of a register every time the blower kicks on.
- Drywall dust or sawdust left in the ducts after a renovation.
- A return grille caked gray within weeks.

Duct cleaning questions we hear in South Fulton
These come up on most duct calls in South Fulton. If yours is missing, call or send the form.
Flex duct
How often should air ducts in your home be cleaned?
There's no set schedule. The EPA ties cleaning to what's in the ducts, not the calendar: visible mold growth, vermin, or heavy dust and debris. Plenty of South Fulton homes go many years without needing it, as long as filters get changed on time.
Can I clean my air ducts myself?
You can vacuum the registers and wipe the grilles. Past that, stop. Flex duct tears easily, the coil and refrigerant lines are a technician's job, and the capacitors near the blower hold a charge after the power is off.
Sheet-metal duct
What are the downsides of duct cleaning?
It doesn't seal a single leak, and rough work can loosen seams or tear flex. Steer clear of sweeping health claims, anyone who says the EPA vouches for them, and chemical fogging: EPA has registered no biocides for insulated duct liners.
How can I tell if there is mold in my air ducts?
Look for growth you can see inside a sheet-metal duct, around a register or on the blower. A musty smell alone doesn't prove it, and dark spots are often plain dust, so we look closely before calling it mold.
On the day
Can you stay in the house during duct cleaning?
Yes, most people do. The system stays off while we work, registers get covered, and the vacuum pulls dust out of the house instead of into the rooms. Expect some noise and no heating or cooling until the job is done.
What time of year is best for duct cleaning?
After tree pollen season. The pine pollen levels peak between late March and mid April. The highest level in Atlanta was 14,801 on March 29, 2025. Once this has passed please book and change your filter.
Dusty vents? Swap the filter, then call us.
Tell us what you see at the vents, whether the house heats with gas or a heat pump, its rough age, and where the ducts run.
