Don’t let energy slip through the cracks

Be Wattsmart and save on duct sealing and duct insulation. When energy is lost through duct surfaces, heating and cooling equipment has to work harder to make up for the loss. As a result, you could be spending too much money to maintain comfort. Duct sealing and duct insulation can cut those heating and cooling costs by 20 percent.
