Air Free Duct Cleaning uses specialized tools that are built specifically for cleaning dryer vents. We use our specialized tools to clean from the entry point, outside of the unit, all the way down to where the ducting terminates in the laundry room. The length of these runs can range from 10'-40'. We also offer residential/commercial HVAC and duct cleaning services. We are NADCA certified, State of Iowa registered, A+ BBB, fully insured and locally owned for over 25 years.
