Before you replace your old furnace, you should learn how energy efficiency should influence your decision. How efficiently your furnace burns fuel and delivers heat to your home has a direct connection to long-term operating expenses.
How to Compare Efficiencies
The most important number for a new gas- or oil-burning furnace is its annual fuel utilization efficiency (AFUE) rating. The AFUE measures how much of the fuel gets converted into heat in a furnace.
The current minimum AFUE for a new residential gas furnace is 78 percent, which means 22 percent of the fuel doesn’t get turned into heat; rather, it goes up the chimney. High-efficiency furnaces run AFUE 90-98 percent. These are condensing furnaces that use two heat exchangers to maximize heat extraction from both the fuel and combustion exhaust.
High-efficiency furnaces are great for energy conservation and savings on utility bills, but they cost much more to purchase. You’ll want to consider a variety of factors when choosing the efficiency level of our new furnace, and then get advice from a trusted HVAC technician.
To get a feel for what range of efficiency will suit your house best, consider these factors:
