Part of possessing and utilizing a furnace is being familiar with the system and understanding when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to note and can disclose to you what kind of efficiency you can look for from your system. If you are not informed of your AFUE, this percentage can be verified at your next furnace maintenance appointment from one of our specialists at All Seasons Heating & A/C Co.

  • Compare your AFUE percentage in relation to money – if your AFUE is 75%, that means that for every $100 you spend on heating your home, only $75 is taken to heat your home.
