Attic Insulation ─── As experts we at A.C.S. agree that the majority of heat loss or gain that takes place in a home is done through its attic. This estimated heat loss can be as high as 45% depending on what type of insulation your attic has. With an alarming potential for heat loss like that it’s easy to see why you need to pay special attention to how your attic is insulated. In winter, when you heat your home that heat rises and your attic insulation is the first line of defense to stop that heat loss and save energy. In summer, hot humid air also penetrates into your attic and makes your home harder to cool. Hot Water Heating ─── After home heating, hot water tanks consume the most energy in your home. Control your home energy costs by choosing a more energy-efficient hot water tank . Owning a new Water Tank helps manage cash flow, and comfort! Get a Smart Solution for Hot Water Heating.
