Furnace Service, AFUE and What They Mean for You in New Castle

Strange temperature changes and the desire for early spring can mess with us as we wait until the end of the winter season. With the random weather this time of year, it’s vital to ensure that your furnace service is taken care of and that your furnace is set for any weather shift. Part of possessing 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 tell you what kind of effectiveness you can expect from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace maintenance appointment from one of our experts at Central Heating & Plumbing.

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


  • The older your furnace is, the smaller 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 with regard to money – if your AFUE is 75%, that means that for every $100 you use heating your home, only $75 is being used to heat your home.

Taking into account the age of your furnace and the likelihood of overspending on your heating costs has hopefully provided some insight into the significance of your furnace’s AFUE. There are many factors that go into picking a new furnace or sticking to your furnace service plan. Over time though, smaller efficiency levels can significantly impact your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and think of it when deciding whether it’s time for furnace replacement.
