Question: How is the efficiency of my furnace measured?
Answer: Central furnace and boiler efficiencies are measured by a metric called "AFUE," or "annual fuel utilization efficiency." This rating is a percentage based on a heating unit's annual fuel consumption vs its annual heat output. Learn more about AFUE at the US Department of Energy.
Question: When should I replace my gas furnace?
Answer: If your furnace is more than 15 years old, or your heat pump is more than 10 years old, it's time to start thinking about replacing your heating system. A new HVAC system will provide new warranties, better efficiencies, and newer features than ever before. Learn more about when to replace your furnace with this article at Energy Star.
