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

December 31, 2015

Interesting temperature changes and the hope of early spring can let us down as we wait until the end of the cold season. With the unpredictable weather this time of year, it’s vital to double check that your furnace service is done and that your furnace is prepared for any weather shift. Part of having and utilizing a furnace is knowing the system and knowing when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to recognize and can disclose to you what kind of effectiveness you can look for 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 professionals at Giordanos Heating and Air Conditioning.

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


  • The older your furnace is, the lower its AFUE will also be. This means less energy efficiency than with a new furnace every 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 spend on heating your home, only $75 is taken to heat your home.

Bearing in mind the age of your furnace and the possibility of overspending on your heating costs has hopefully offered some perception into the weight of your furnace’s AFUE. There are many factors that go into selecting a new furnace or remaining with your furnace service plan. Over time still, lower efficiency levels can radically impact your energy usage, monthly bills and ease. Don’t ignore the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
