The climbing costs of home heating fuel make affordable home upgrades all the more valuable. Reduce waste and enhance home comfort by sealing all heating and cooling ducts along seams and connections with duct sealant (mastic) or metal-backed tape (never duct tape, as it doesn’t have the required staying power), followed by insulation wrap. Also consider upgrading your home’s insulation. A visit to the U.S. Department of Energy’s Insulation Recommendations page will provide guidance for your specific climate and location.
