What is Afue and What Does it Mean for My Energy Bill

AFUE is an acronym for Annual Fuel Utilization Efficiency for furnaces or boilers. So, the AFUE number on your furnace represents the percentage of fuel that is actually converted into heat when your furnace is running. So, if your furnace's AFUE number is 80, then that means that 80% of the of the fuel that it takes is is used for heat, while the remaining 10% is wasted in the exhaust. So, one can conclude that the higher AFUE number on your furnace will mean a smaller energy bill. For example, lets say you have a furnace with an AFUE of 65 AFUE. If you upgraded to the minimum standards of efficiency within the state of California, 80 AFUE, you are looking at an energy bill that is nearly 20% cheaper than your current bill. Practically, with normal heating use, this translates into nearly $200 of savings per year. Furnaces today can have up to a whopping 98 AFUE. Imagine the savings! Is your furnace on its last legs? If so, do you want to perform a costly repair your old unit, does it have a few more years left, or is it time for the newer higher efficiency unit. Zion Custom Air loves to educate our clients so that they can make informed decisions about questions like these. No job is too large or too small for our specialists.
