Fire Residue Cleaning for Kennesaw Air Ducts

Kennesaw air duct cleaning is vital to an overall restoration plan for properties damaged in a fire. Without professional cleaning, the unfortunate reality is that toxic and corrosive soot that enters your air ducts will continuously contaminate your home. Ductwork provides the "highway" heating, ventilation, and cooling (HVAC) systems used to move warm or cooled air throughout a building. Airborne smoke and soot produced by a fire can hop on the "highway" after penetrating the ducts, eventually recirculating harmful residues and odors to spread to all spaces the HVAC equipment serves.

How Do Smoke and Soot Get Inside Ductwork?

  • The Roles of HVAC Vents 

Fire residues travel through vents to clog and soil the inside of air ducts. Smoky air moves into the ductwork, which is warmed or cooled by the enclosed air handler and then blown back into your living areas. Vents act as the entries and exit for this continuously circulating system. Two types of vents, covered by open-work grilles or registers, are visible on walls, ceilings, or sometimes floors:

Return Vents

Return vents use negative pressure (suction) to pull "used" air from a room, looping it through equipment (air handlers and blowers) that conditions the air. These vents do not have moveable slats, and you might feel a sucking sensation if you put your hand against one.

Supply Vents

Supply vents use positive pressure to blow conditioned air (heated or cooled) by the HVAC air handler into rooms. Hold your hand near a grille or register. If you feel an outward movement of warm or cooled air, you've found a supply vent, usually equipped with adjustable louvers to direct flow.

  • Active Versus Passive Smoke Damage

Active Smoke Damage

An operating HVAC system uses negative pressure to force smoke and soot-filled air inside the return vents. The air handler and blower become coated with soot, pushing debris along with the conditioned air as it goes through the ductwork trunk lines and branches heading towards and through supply vents. Residues then spread both in and out of the HVAC system. Over a day, the contaminated air in an operating HVAC system can recycle up to eight times.

Passive Smoke Damage

Passive air duct damage occurs when the HVAC system is off during a fire. Natural air movement propels smoke vapor and soot in and out of the ducts. Super-heated air currents accelerate this penetrating action during a blaze. Once the system reengages, the fire residues stir and move out and back into the ducts.

Professional Duct Cleaning Expectations

Duct cleaning in Kennesaw is crucial, whether fire damage is active or passive. AdvantaClean of Marietta conforms to The National Air Duct Cleaners Association (NADCA) recommendations. Trained technicians conduct a remote visual internal inspection of the ductwork, air handler, blowers, and other equipment. All parts of the HVAC system, including coils and air handler, undergo source removal after containment of the HVAC system with negative pressure and sealing of vents and non-airtight lengths of ducting. Source removal involves pairing two types of cleaning interventions together: 

  • Mechanical agitation to dislodge residues from the air duct's walls using a range of cleaning tools specifically made for HVAC systems, for example, duct cleaning whips and compressed air. 

  • Commercial-grade extraction to remove the loosened dust and debris, secured in containers for disposal outside of the home
