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

December 31, 2015

Interesting temperature changes and the desire for early spring can mess with us as we wait until the end of the cold season. With the erratic weather this time of year, it’s vital to make sure that your furnace service is taken care of and that your furnace is ready for any weather change. Part of having and operating a furnace is being familiar with 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 inform you what kind of productivity you can anticipate from your system. If you are not informed of your AFUE, this percentage can be clarified at your next furnace tune-up appointment from one of our experts at Lycoming Heating Company.

So, what does this AFUE rating suggest for you? What types of things should you consider with AFUE?


  • The older your furnace is, the lower its AFUE will also be. This means reduced energy efficiency compared to a new furnace in the winter when your system is in use.
  • Compare your AFUE percentage proportionate 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 provided some understanding into the weight of your furnace’s AFUE. There are many things that go into selecting a new furnace or staying in your furnace service plan. Over time still, lower efficiency levels can significantly effect your energy usage, monthly bills and coziness. Don’t overlook the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
