When you go shopping for a new furnace, heat pump, air conditioner, or water heater, the price tag tells only part of the story. Before you buy, read the EnergyGuide label on that new furnace to find out how energy efficient it is. Then compare it to the label on another model and brand. EnergyGuide labels show how much energy one model uses in comparison with others. Although some high-efficiency appliances may cost more at the outset, they can save money by lowering your energy bills.
