Furnace Service, AFUE and What They Mean for You in Colorado Springs

Interesting temperature changes and the hope of early spring can mess with us as we wait until the end of the winter season. With the random weather this time of year, it’s crucial to make sure that your furnace service is done and that your furnace is ready for any weather swing. Part of having and utilizing a furnace is knowing the system and knowing when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to know and can disclose to you what kind of productivity you can look for from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace maintenance appointment from one of our specialists at Mitchell Heating.

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


  • The older your furnace is, the littler 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 spent to heat your home.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully offered some insight into the weight 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 still, smaller efficiency levels can significantly influence your energy usage, monthly bills and ease. Don’t overlook the AFUE rating of your furnace and consider it when choosing whether it’s time for furnace replacement.
