Typically we suggest a homeâs air ducts be cleaned every five to eight years. Homeowners with children, pets, respiratory issues or a compromised immune system may want to get their HVAC duct system cleaned more often. The better filtration the system has cuts down on cleaning frequency.
Air duct cleaning for most homes costs on average between $300 and $500. Dear Angie: Iâm looking to have my air ducts cleaned but Iâve seen prices vary from $99 to $800. I have not been given an explanation, that I believe, that describes the reason for the price difference.
