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

Interesting temperature changes and the expectation of early spring can keep us holding out as we wait until the end of the winter season. With the random weather this time of year, it’s important to ensure that your furnace service is done and that your furnace is ready for any weather shift. Part of possessing and operating a furnace is understanding the system and understanding when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to know and can inform you what kind of efficiency you can look for from your system. If you are unaware of your AFUE, this percentage can be determined at your next furnace maintenance appointment from one of our experts at Ben Maines Air Conditioning, Inc..

So, what does this AFUE rating mean for you? What types of things should you take into account with AFUE?


  • The older your furnace is, the littler its AFUE will also be. This means reduced energy efficiency compared to a new furnace every winter when your system is in use.
  • Compare 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 spent to heat your home.

Taking into account the age of your furnace and the likelihood of overspending on your heating costs has hopefully provided some insight into the weight of your furnace’s AFUE. There are many elements that go into choosing a new furnace or sticking to your furnace service plan. Over time though, lower efficiency levels can drastically 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.
