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

December 31, 2015

Strange temperature changes and the hope of early spring can mess with us as we wait until the end of the cold season. With the unpredictable weather this time of year, it’s vital to double check that your furnace service is done and that your furnace is prepared for any weather change. Part of having and utilizing a furnace is understanding the system and preparing for when it might call for 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 efficiency you can look for from your system. If you are unaware of your AFUE, this percentage can be clarified at your next furnace tune-up appointment from one of our professionals at True Temp Heating & Air Inc.

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 lower its AFUE will also be. This means less energy efficiency than with a new furnace each 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 taken to heat your home.

Bearing in mind 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 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 coziness. Don’t ignore the AFUE rating of your furnace and consider it when choosing whether it’s time for furnace replacement.
