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

December 31, 2015

Strange temperature changes and the desire for early spring can let us down 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 taken care of and that your furnace is ready for any weather change. Part of owning and operating a furnace is knowing the system and knowing when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to recognize and can disclose to you what kind of effectiveness you can anticipate from your system. If you are unaware of your AFUE, this percentage can be clarified at your next furnace maintenance appointment from one of our specialists at Anderson Heating & A/C.

So, what does this AFUE rating indicate for you? What types 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 in the winter when your system is in use.
  • Compare your AFUE percentage with regard to money – if your AFUE is 75%, that means that for every $100 you devote to heating your home, only $75 is spent to heat your home.

Bearing in mind the age of your furnace and the potential of overspending on your heating costs has hopefully given some understanding into the significance of your furnace’s AFUE. There are many factors that go into selecting a new furnace or sticking to your furnace service plan. Over time however, lower efficiency levels can radically influence 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.
