Residential air duct cleaning is crucial to you and your families’ health as well as the cleanness of your home. When your vents are filled with lint, debris, dust, bacteria, or even mold build-up it can cause them to stop cleaning the air properly and instead pollute your airflow leaving you with dirty air. When this happens, you will notice that no matter how much you sweep and clean those floors and walls, they will still not look spotless or get dirty no sooner than later which is a result of the air ducts letting out that dirt right back into your home.
