Your homes ductwork is like your body’s vascular system. Supply ductwork carries treated air to the rooms of your house while return ductwork brings it back to the central system. It is important to have a properly designed air delivery system to maintain a comfortable home. Imagine your body with only half the veins needed to carry the blood back to your heart. The EPA estimates that up to 30% of a system’s efficiency may be lost because of duct leakage.
Ultraviolet light is recognized as an acceptable sterilization tool. Most often installed in the duct by the furnace, UV lighting can help prevent the growth of bacteria, molds, and viruses where the light comes in contact with any microbes. UV light emitters also help to keep some functional parts of your cooling system clean, maintaining its efficiency.
