Why is duct insulation important?
Insulating ductwork is something every homeowner should do. The most significant benefit is reducing energy consumption and prolonging the life of the system. It will also significantly increase the comfort of the home. Insulated ducts will allow the HVAC system to heat or cool rooms more quickly and reduce noise.
