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.
You should have your ducts cleaned for the following situations: - If you have a problem with moisture in your ducts. If the conditions causing the mold growth in the first place are not corrected, mold growth will recur. - If you are moving into a newly constructed house.
