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

December 31, 2015

Strange temperature changes and the desire for early spring can mess with us as we wait until the end of winter. With the random weather this time of year, it’s important to ensure that your furnace service is done and that your furnace is prepared for any weather change. Part of having and operating a furnace is knowing the system and knowing when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to note and can tell you what kind of productivity you can expect from your system. If you are not informed of your AFUE, this percentage can be clarified at your next furnace maintenance appointment from one of our professionals at Strine's Heating & Air Conditioning.

So, what does this AFUE rating suggest 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 less energy efficiency compared to a new furnace each winter when your system is in use.
  • Consider 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.

Considering the age of your furnace and the likelihood of overspending on your heating costs has hopefully given some insight 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 however, decreased efficiency levels can significantly influence your energy usage, monthly bills and coziness. Don’t disregard the AFUE rating of your furnace and consider it when choosing whether it’s time for furnace replacement.
