Thinking of purchasing a new heating and cooling system for your home? Although high-efficiency systems cost more initially, they can significantly reduce your monthly utility bills. The Lennox Web site has a handy Energy Savings Calculator that shows how much you can save over a five-year period based on different SEER (Seasonal Energy Efficiency Ratio) and AFUE (Annual Fuel Utilization Efficiency) ratings. The higher the SEER or AFUE rating, the greater the savings. You should also check the yellow-and-black EnergyGuide label for estimates of how much energy the unit uses annually, based on average household usage patterns and the yearly energy cost, based on the national average price of energy. The label also features a bar graph which shows a range of efficiencies for all similar heating and cooling systems.
