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

December 31, 2015

Interesting temperature changes and the desire for early spring can keep us holding out as we wait until the end of winter. With the random weather this time of year, it’s vital to double check that your furnace service is done and that your furnace is ready for any weather swing. Part of owning and using a furnace is being familiar with the system and understanding when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to know and can disclose to you what kind of effectiveness you can anticipate 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 PWA Heating & Cooling Inc.

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


  • The older your furnace is, the littler 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.
  • 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 spent to heat your home.

Taking into account the age of your furnace and the likelihood of overspending on your heating costs has hopefully offered some understanding into the significance of your furnace’s AFUE. There are many things that go into picking a new furnace or remaining with your furnace service plan. Over time though, decreased efficiency levels can radically effect your energy usage, monthly bills and coziness. Don’t disregard the AFUE rating of your furnace and reflect on it when choosing whether it’s time for furnace replacement.
