According to the EPA, you can expect professional air duct cleaning to cost between $450 and $1,000, depending on the size and type of your ductwork system, system accessibility, climate region, and level of dirt or mold.

What is air duct cleaning?

Professional air duct cleaning should involve the entire heating and air system. Before making recommendations, they should conduct an assessment. A company should be able to use a small camera inserted into your ductwork to evaluate the extent of any problem. They can then show you what the camera found. A certified company will use specialized equipment to dislodge debris stuck to the inside of your ductwork and essentially vacuum it out through a large hose connected to your HVAC system. Cleaning (and disinfecting) the whole system is especially important if the reason for the cleaning is mold growth. It’s also important to know that you have to resolve the cause of the moisture that allowed mold growth in the first place, or it will come back.
