Furnace Service, AFUE and What They Mean for You in West Valley City

Strange temperature changes and the hope of early spring can mess with us as we wait until the end of the winter season. With the erratic weather this time of year, it’s vital to double check that your furnace service is taken care of and that your furnace is ready for any weather shift. Part of having and using a furnace is understanding the system and knowing when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to note and can inform you what kind of efficiency you can look for from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace tune-up appointment from one of our professionals at Select Comfort System Heating & Air Conditioning.

So, what does this AFUE rating mean for you? What kinds of things should you consider 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.

Bearing in mind the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some understanding into the significance of your furnace’s AFUE. There are many elements 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 coziness. Don’t ignore the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
