Air ducts are designed to support your HVAC system. While functioning air ducts keep your home at a comfortable temperature, over time, dust, debris, and dirt can accumulate in these air ducts. Regular duct cleanings will help you maintain your HVAC system. When the contractor arrives to clean the ducts, make sure to give them a walkthrough of the home first. Be sure to point out where the air vents are as well as other elements of the AC system. Learn more about duct cleaning from Classic Aire Care.
