Furnace Service, AFUE and What They Mean for You in Wharton

Interesting temperature changes and the desire for early spring can let us down as we wait until the end of the cold season. With the erratic weather this time of year, it’s important to make sure that your furnace service is taken care of and that your furnace is ready for any weather change. Part of possessing and utilizing a furnace is understanding the system and knowing when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to recognize and can inform you what kind of efficiency you can expect from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace service appointment from one of our professionals at Faust Air Conditioning and Heating.

So, what does this AFUE rating suggest for you? What types of things should you take into account with AFUE?


  • The older your furnace is, the smaller its AFUE will also be. This means reduced energy efficiency than with a new furnace each winter when your system is in use.
  • Consider 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.

Taking into account the age of your furnace and the potential of overspending on your heating costs has hopefully given some perception into the importance of your furnace’s AFUE. There are many factors that go into picking a new furnace or staying in your furnace service plan. Over time however, decreased efficiency levels can drastically effect your energy usage, monthly bills and ease. Don’t disregard the AFUE rating of your furnace and think of it when determining whether it’s time for furnace replacement.
