The National Air Duct Cleaners Association was formed to help consumers avoid scams. As a member of their association, we encourage anyone seeking duct cleaning services to follow their guidelines for

choosing an air duct cleaning company:

  • Go to the NADCA Web site at and enter your zip (postal) code to find a NADCA member in your area.
  • When speaking to a contractor, make sure they can show proof of NADCA membership and certification.
  • Make sure the contractor will conduct a thorough inspection of your HVAC system and alert you to any problems.
  • Make sure the contractor will clean all of the HVAC system components including, at a minimum: air ducts, coils, drain, registers, grills, air plenum, blower motor and assembly, heat exchanger, air filter, and air cleaner.
