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

December 31, 2015

Strange temperature changes and the desire for early spring can keep us holding out as we wait until the end of the cold season. With the erratic weather this time of year, it’s crucial to ensure that your furnace service is done and that your furnace is prepared for any weather change. Part of owning and operating a furnace is being familiar with the system and preparing for when it might require 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 expect from your system. If you are unaware of your AFUE, this percentage can be clarified at your next furnace service appointment from one of our experts at House of Heating Incorporated.

So, what does this AFUE rating mean 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 every 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 possibility of overspending on your heating costs has hopefully provided some insight into the weight of your furnace’s AFUE. There are many elements that go into picking a new furnace or sticking to your furnace service plan. Over time however, smaller efficiency levels can radically impact your energy usage, monthly bills and coziness. Don’t overlook the AFUE rating of your furnace and think of it when determining whether it’s time for furnace replacement.
