Some of the best methods professionals use for cleaning air ducts include a rotary brush system or a push-pull vacuum system. A rotary brush will scrub dust and debris loose from the inside walls of your air ducts. Typically, the rotary brush will catch most of the dust, but a vacuum will help remove any remaining loose particles. The push-pull method forces air into the duct from one end, and a vacuum on the other end pulls that air and the dust it loosens.

Although you may only need to clean your air ducts every three years or so, keeping them clean and clear can offer several benefits including:

• Improve indoor air quality

• Help alleviate allergy symptoms by reducing mold and pollen in the air

• Save on energy costs by allowing maximum airflow efficiency

• Reduce odor

• Prevent mold and mildew 

• Help extend the life of your HVAC system 

• Reduce the risk of house fires from dust and debris build up

The cost for air duct cleaning is about $380, on average. However, costs can range between $270 and $500, depending on location, number of vents, duct accessibility, and how much cleaning is required. Additional factors can impact the cost of cleaning your air ducts, such as removing pests, mold and mildew, asbestos, and other unforeseen needs. Any repairs will also add to the cost of the job.
