Pet Hair and Dander Buildup in a Dunwoody Club Forest Condo

BeforeAfter

The condo had two golden retrievers and a duct system that hadn’t been touched since the building went up in the early 2000s. The return side was so packed with fur that airflow to the back bedroom was barely moving. We ran the Rotobrush through the main trunks and the Nikro negative-air machine pulled the loosened material into a HEPA-filtered containment unit, not back into the condo. The result was a duct interior you could wipe a white glove through, and the owner stopped finding dog hair on the ceiling vents every week.

Post-Renovation Drywall Dust in a Riverside Drive Colonial

BeforeAfter

After a kitchen remodel, this family noticed a fine white film appearing on furniture in rooms far from the construction. That film was drywall dust hanging inside the ductwork, circulating every time the furnace kicked on. We sealed off each register, scrubbed the interior surfaces with the rotary brush, and used the negative-air setup to keep the dust from migrating during the work. By the time we finished, the air felt noticeably lighter and the film never came back.

Condensation and Mold Spotting in a Mount Vernon Woods Crawlspace System

BeforeAfter

This crawlspace system in Mount Vernon Woods was fighting Sandy Springs humidity. The flex ducts were sweating, and where moisture sits in a dark cool duct, biological growth follows. We removed the contaminated sections, cleaned the remaining runs thoroughly, and sealed the seams with duct mastic so warm humid air couldn’t keep getting pulled into the system. The damp smell in the hallway disappeared within two days, and the registers stopped weeping in the afternoons.

Dryer Vent Lint Blockage in a Highpoint Townhome

The homeowner said the dryer was taking two cycles to finish a load and the laundry room felt humid even with the window cracked. We found the vent run packed with compacted lint from ten years of heavy use, with the exhaust flap barely opening. That level of blockage is how dryer fires start. We pulled the lint out through the full run, confirmed airflow at the exterior vent, and left the space clear. The dryer now finishes a full load in one cycle and the room stays dry.

Duct Sealing for a Drafty Living Room in a North Springs Split-Level

The front living room in this North Springs split-level never reached the temperature on the thermostat, no matter how long the system ran. The problem wasn’t the furnace. A return plenum in the basement had gaps and old duct tape that had long since cracked away, so the system was pulling whatever air it could from the basement instead of the living room. We cleaned the joint, applied duct mastic with mesh reinforcement, and checked the rest of the accessible ductwork for similar leaks. The living room now warms up with the rest of the house.
