Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.

Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors.

Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.
