Since about 40% of your homes energy costs go toward heating and cooling, you can save more than a third of that cost by sealing ducts and also insulating them from losing the warm heating air or the cool air conditioning as it travels to each room.
Have your ducts professionally sealed to reduce leakage to the ENERGY STAR specification of 10% maximum.
The ROI Calculation is based on the one time service cost and savings of $25 a month over the course of the year.
Metallic tape is key to sealing the connections between duct sections so that they do not leak, but also consider using a professional who will have additional ways of sealing harder to reach and other types of dust leaks.
