With the growing concern about indoor air pollution, interior duct and vent cleaning has become increasingly popular over the years. If a heating and cooling system is not properly installed or maintained, the components can become contaminated with dust, pollen and other particles. This contamination can lead to the pollution of the indoor air supply, and can even cause allergic reactions or other side effects.

Duct cleaning involves the cleaning of the individual parts of a heating and cooling system or forced air system. According to the EPA (Environmental Protection Agency), the parts that should be cleaned by your professional service provider include, but are not limited to: supply and return air ducts and registers, heating and cooling coils, grilles and diffusers, heat exchangers, fan motors, fan housing and air handling unit housing (1).

When choosing a professional duct cleaning provider, it is important to choose a service provider who will clean your system in its entirety, and is qualified to do so. The EPA states a professional provider should inspect and clean the following:

  • Open access ports or doors to allow entire system to be cleaned and inspected
  • Inspect the system before cleaning for asbestos materials
  • Use vacuum that exhausts particles outside of home or HEPA vacuuming equipment
  • Protect carpet & household furnishings during cleaning
  • Use controlled brushing of duct surfaces to dislodge dust and other particles
  • Only use soft-bristled brushes for fiberglass duct board and sheet metal ducts lined with fiberglass
  • Protect duct work and seal and re-insulate any access holes they have made
  • Follow NADCA’s standards for air duct cleaning and NAIMA’s recommended practice for ducts (1)
