Even though installing a new furnace is a fairly substantial investment, an upgraded replacement can provide many benefits to your home. Improved Efficiency and Lower Fuel Costs One major benefit of replacing your old furnace is that your new unit is almost guaranteed to be more energy efficient. A 25-year-old furnace is likely only a low- or medium-efficiency unit with an AFUE (Annual Fuel Utilization Efficiency) of only around 80%. Even if you installed a new furnace that was also rated at 80 AFUE, it is still certain to work better and use less energy. This is simply because the energy efficiency and effectiveness of all gas furnaces tend to decline as the appliance ages. If you were instead to opt for a high-efficiency condensing furnace with an AFUE in the mid to upper 90s, you could save a significant...
