Duct Sealing Marietta GA
Aeroseal Certified · Cut Energy Bills Up to 30% · Same-Day Inspection Available
If your Marietta home has rooms that never seem to cool down, or your energy bills keep climbing even with a working HVAC system, leaky ductwork is often the hidden cause. Pure Air Atlanta provides certified duct sealing in Marietta, GA, using Aeroseal technology to permanently seal leaks from the inside, without tearing open walls or ceilings.
Marietta's older homes, especially those in East Cobb, Kennesaw Mountain-adjacent neighborhoods, and near historic Marietta Square, often have ductwork installed decades ago. Over time, joints separate, connections loosen, and conditioned air leaks into attics, crawl spaces, and wall cavities before it ever reaches your living room. The ENERGY STAR program notes that duct leakage is a leading cause of wasted heating and cooling energy in homes with older ductwork.
Signs Your Marietta Home Needs Duct Sealing
- Some rooms are noticeably hotter or colder than others
- Your energy bills have crept up without a change in usage
- You feel drafts near vents, walls, or the attic hatch
- Dust builds up faster than it should between cleanings
- Your HVAC system runs constantly but never quite catches up
How Aeroseal Duct Sealing Works
Unlike traditional duct sealing, which relies on manually taping accessible joints, Aeroseal is a computer-monitored process that seals leaks from the inside of the ductwork itself, including gaps hidden inside walls and ceilings that a technician could never physically reach.
