Old homes and old HVAC systems bring the potential for asbestos — here’s what HVAC contractors and duct cleaning professionals need to know if they run into it on a jobsite.
Over time, dirt, dust, pet dander, debris, and more accumulate in air ducts. And since the HVAC system works basically as a whole-home vacuum, all of that is recirculated through homes when the HVAC system runs, unless the ducts are cleaned out.
You perform maintenance each year, but by the next maintenance visit, dirt and grime are in the equipment again. Have you ever wondered why this happens?
The National Air Duct Cleaners Association's 2023 Fall Technical Conference is scheduled for September 7-9 in Grapevine, Texas, near Dallas. Those in the field who have not attended before can apply for a scholarship.
