Overview (3) Heidi Klum was born in Bergisch Gladbach, a small city near Cologne, Germany, in 1973. Her career as a top fashion model and swimsuit star began almost by accident when, on a lark, she submitted photos to a model competition hosted by Petra, a young woman's magazine.
The National Air Duct Cleaners Association recommends getting your air ducts cleaned every three to five years. Ed Mack, owner of Air Duct Professionals in Lake Elsinore, California, says homeowners should consider doing it every two to five years, depending on their circumstances.
Your air ducts probably need cleaning if the filters or air returns are dusty and dirty or if you remove a vent cover and can see lots of dirt and debris inside the vent. The average cost for air duct cleaning service is $300-$500 for a 1500 square foot home. Professional air duct cleaners clean and disinfect the vent returns and filters, as well as use high-pressure âvacuumsâ to remove dirt and debris from the ducts themselves.
