How can duct cleaning help save me money?

If you leave your air duct as such without cleaning, debris and dirt will start accumulating in the filter and the heating/cooling unit. A clogged system will have to work harder and longer to achieve the desired heating and cooling. This will increase the amount o energy required and can significantly increase energy costs. But if regular home air duct cleaning is conducted, it will help you in saving more by running your system efficiently.
