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

December 31, 2015

Curious temperature changes and the desire for early spring can let us down as we wait until the end of winter. With the erratic weather this time of year, it’s vital to double check that your furnace service is done and that your furnace is ready for any weather change. Part of having and utilizing a furnace is understanding 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 recognize and can tell you what kind of productivity you can anticipate from your system. If you are unaware of your AFUE, this percentage can be determined at your next furnace service appointment from one of our professionals at Northglenn Heating & Air Conditioning, Inc..

So, what does this AFUE rating mean for you? What kinds of things should you think on with AFUE?


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

Bearing in mind 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 factors that go into picking a new furnace or remaining with your furnace service plan. Over time though, lower efficiency levels can significantly effect your energy usage, monthly bills and ease. Don’t disregard the AFUE rating of your furnace and consider it when choosing whether it’s time for furnace replacement.
