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

Strange temperature changes and the desire for early spring can mess with us as we wait until the end of winter. With the erratic weather this time of year, it’s crucial to ensure that your furnace service is done and that your furnace is prepared for any weather change. Part of owning and utilizing a furnace is understanding the system and preparing for when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to recognize and can tell you what kind of productivity you can expect from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace tune-up appointment from one of our experts at Oak Point Heating and Air LLC.

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 devote to heating your home, only $75 is taken 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 importance of your furnace’s AFUE. There are many things that go into picking a new furnace or sticking to your furnace service plan. Over time though, smaller efficiency levels can radically influence your energy usage, monthly bills and ease. Don’t overlook the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
