What is air duct cleaning and why is it needed?

Air duct cleaning is the process of removing dust, debris, and other contaminants from the air ducts of a building’s HVAC system. The overall goal of cleaning air ducts is to help improve the indoor air quality and to increase the efficiency of the heating and cooling system.

Although air duct cleaning is not typically considered a necessary service, there are many factors that go into determining if duct cleaning is needed. If you are experiencing any of these issues it may be time to book an air duct inspection.

  • An overaccumulation of dust, dirt and/or debris. Overtime dust and dirt can build up reducing the efficiency of the HVAC system and potentially affecting the indoor air quality. This is more of a factor when the air filter is not replaced regularly.
  • If you have recently experienced water damage in your home or business it is beneficial to inspect the duct work for any mold or moisture.
  • Pets and other animals can also cause problems in air ducts by shedding hair and dander or building nests.
  • Air ducts can also become infested with mold, which can cause health problems for building occupants and damage the ducts themselves.
  • If a business or home has recently undergone renovation or construction. Debris from the remodeling work and construction dust can get into the air ducts.

In addition to many factors contributing to the need for air duct cleaning there are also different ways to perform the duct cleaning service.

  • Brush and vacuum cleaning: This method involves using specially designed brush heads that simultaneously spin while the powerful vacuum removes dust and debris. This method works much like a vacuum cleaner on floors. As the brush is agitating and scrubbing the duct walls the vacuum is sucking up the dirt.
  • Negative air cleaning: Another affective way to cleaning air ducts is putting the system under negative pressure. With this process you are blocking off the openings to the air ducts and cutting an access whole where a large hose is connected. Whips or brushes are then used to agitate the dirt and debris and the powerful vacuum removes everything.

Some air duct cleaning providers also use video inspection equipment to help determine if air duct cleaning is beneficial. Once the dirt and debris has been removed from your air ducts a sanitizing and disinfecting solution can be sprayed into the duct system to help with any bacteria, mold, or other contaminants.
