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

Interesting temperature changes and the desire for early spring can mess with us as we wait until the end of the winter season. With the random weather this time of year, it’s crucial to make sure that your furnace service is complete and that your furnace is set for any weather change. Part of having and utilizing a furnace is understanding the system and preparing for when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to recognize 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 verified at your next furnace tune-up appointment from one of our experts at Rescue Heating & Air .

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


  • The older your furnace is, the smaller its AFUE will also be. This means not as much energy efficiency than with 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.

Bearing in mind the age of your furnace and the possibility of overspending on your heating costs has hopefully given some understanding into the weight of your furnace’s AFUE. There are many elements that go into selecting a new furnace or remaining with your furnace service plan. Over time though, smaller efficiency levels can radically effect your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
