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

December 31, 2015

Curious temperature changes and the desire for early spring can mess with us as we wait until the end of winter. With the unpredictable weather this time of year, it’s vital to make sure that your furnace service is done and that your furnace is set for any weather swing. Part of having and using a furnace is being familiar with the system and understanding when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to recognize and can inform you what kind of effectiveness 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 Assured Appliance and Heating & Air.

So, what does this AFUE rating mean for you? What sorts of things should you take into account with AFUE?


  • The older your furnace is, the littler its AFUE will also be. This means less energy efficiency than with a new furnace every 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 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 significance of your furnace’s AFUE. There are many elements that go into choosing a new furnace or staying in your furnace service plan. Over time however, decreased efficiency levels can drastically influence your energy usage, monthly bills and coziness. Don’t disregard the AFUE rating of your furnace and think of it when deciding whether it’s time for furnace replacement.
