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

Curious temperature changes and the expectation of early spring can let us down 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 change. Part of having and operating a furnace is understanding the system and knowing when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to know and can disclose to you what kind of effectiveness you can look for 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 All Elements Heating & Air LLC.

So, what does this AFUE rating suggest for you? What types of things should you consider with AFUE?


  • The older your furnace is, the smaller its AFUE will also be. This means reduced energy efficiency compared to a new furnace each 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 spend on 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 given some perception into the importance of your furnace’s AFUE. There are many factors that go into selecting a new furnace or sticking to your furnace service plan. Over time still, lower efficiency levels can significantly influence your energy usage, monthly bills and ease. Don’t disregard the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
