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

December 31, 2015

Interesting temperature changes and the desire for early spring can mess with us 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 done and that your furnace is set for any weather change. Part of owning and using a furnace is knowing the system and understanding when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to recognize and can disclose to you what kind of productivity you can anticipate from your system. If you are not informed of your AFUE, this percentage can be determined at your next furnace maintenance appointment from one of our professionals at Select Comfort Systems Heating & Air Conditioning.

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


  • The older your furnace is, the lower its AFUE will also be. This means reduced energy efficiency paralleled to a new furnace in the winter when your system is in use.
  • Think about your AFUE percentage with regard to money – if your AFUE is 75%, that means that for every $100 you use heating your home, only $75 is being used to heat your home.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully given some perception into the importance of your furnace’s AFUE. There are many things that go into picking a new furnace or remaining with your furnace service plan. Over time still, decreased efficiency levels can significantly effect your energy usage, monthly bills and comfort. Don’t ignore the AFUE rating of your furnace and think of it when choosing whether it’s time for furnace replacement.
