Confused about AFUE ratings and heating stages? We break down everything you need to know to select the perfect furnace for your home's size and budget.
Selecting a new furnace involves more than just picking a brand. You need to consider the AFUE (Annual Fuel Utilization Efficiency) rating, which measures how efficiently the unit converts fuel into heat.
Understanding AFUE
Higher ratings mean lower bills. A 95% AFUE rating means 95 cents of every dollar spent on gas goes toward heating your home, while only 5 cents is lost through the chimney.
Heating Stages
You also need to decide between single-stage, two-stage, or modulating furnaces based on your comfort needs and budget. Modulating furnaces provide the most consistent temperature control.
