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

Strange temperature changes and the hope of early spring can keep us holding out as we wait until the end of the cold season. With the unpredictable 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 swing. Part of having and using a furnace is being familiar with the system and preparing for when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to note and can disclose to you what kind of efficiency you can expect 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 Wallpe Heating & Cooling.

So, what does this AFUE rating suggest for you? What sorts of things should you think on with AFUE?


  • The older your furnace is, the smaller its AFUE will also be. This means not as much energy efficiency compared to a new furnace every winter when your system is in use.
  • Consider your AFUE percentage in relation to money – if your AFUE is 75%, that means that for every $100 you devote to heating your home, only $75 is spent to heat your home.

Taking into account the age of your furnace and the potential of overspending on your heating costs has hopefully provided some perception into the importance of your furnace’s AFUE. There are many elements that go into selecting a new furnace or sticking to your furnace service plan. Over time still, lower efficiency levels can significantly impact your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and reflect on it when choosing whether it’s time for furnace replacement.
