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

December 31, 2015

Curious temperature changes and the expectation of early spring can keep us holding out as we wait until the end of winter. With the random weather this time of year, it’s crucial to ensure that your furnace service is done and that your furnace is set for any weather swing. Part of having and operating a furnace is understanding the system and knowing when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to know and can inform you what kind of efficiency you can anticipate 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 experts at Street Heating and Cooling.

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

Taking into account the age of your furnace and the potential of overspending on your heating costs has hopefully given some insight into the importance of your furnace’s AFUE. There are many things that go into choosing a new furnace or staying in your furnace service plan. Over time still, smaller efficiency levels can radically impact your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and think of it when deciding whether it’s time for furnace replacement.
