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

Strange temperature changes and the desire for early spring can keep us holding out as we wait until the end of winter. With the erratic 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 possessing and utilizing 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 note and can disclose to you what kind of effectiveness you can anticipate from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace tune-up appointment from one of our experts at Lycoming Heating Company.

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 lower its AFUE will also be. This means not as much energy efficiency compared to a new furnace in the winter when your system is in use.
  • Consider 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 being used to heat your home.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some perception into the weight of your furnace’s AFUE. There are many elements that go into picking a new furnace or remaining with your furnace service plan. Over time though, lower efficiency levels can significantly influence your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and think of it when choosing whether it’s time for furnace replacement.
