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.
Dryer vent ducts should be inspected at least once a year to reduce the risk of fires and carbon monoxide poisoning. If you hire a professional to clean your vent, expect to pay between $75 to $150, depending on the length and location of the vent.
