How to Clean Cement Air Ducts

Cleaning the air ducts in your home not only improves air quality but also lowers your heating and cooling costs. Cleaning every two years is recommended; changing your heating and cooling system filters more frequently — from monthly to quarterly — will improve both air quality and system efficiency. Also, frequent filter changing also means less work when cleaning the ducts. You can hire a professional or save money and do it yourself.
