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

Strange temperature changes and the hope of early spring can let us down as we wait until the end of winter. With the unpredictable weather this time of year, it’s crucial to make sure that your furnace service is complete and that your furnace is ready for any weather change. Part of owning and utilizing a furnace is being familiar with the system and knowing when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to recognize and can inform you what kind of productivity you can anticipate 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 specialists at Craig's Heating & Cooling.

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


  • The older your furnace is, the littler its AFUE will also be. This means reduced energy efficiency compared to a new furnace in the 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 use 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 given some insight into the weight of your furnace’s AFUE. There are many factors that go into choosing a new furnace or remaining with your furnace service plan. Over time however, decreased efficiency levels can significantly effect your energy usage, monthly bills and coziness. Don’t overlook the AFUE rating of your furnace and consider it when choosing whether it’s time for furnace replacement.
