To find an air duct cleaning service provider, the Environmental Protection Agency (EPA) recommends going through the National Air Duct Cleaning Association (NADCA), through whom you can find qualified HVAC technicians. Because air duct cleaning is a fairly new industry, consumers must watch out for providers who make promises about the benefits of duct cleaning, since no such claims have been approved by the EPA. The providers should not recommend duct cleaning as a routine procedure. They should make no guarantees about the improvement of your air quality, nor should they claim to be certified by the EPA.
