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

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 important to double check that your furnace service is taken care of and that your furnace is set 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 an important measurement to recognize and can inform you what kind of efficiency you can anticipate from your system. If you are unsure of your AFUE, this percentage can be clarified at your next furnace maintenance appointment from one of our specialists at All Weather Heating & Air Conditioning Inc.

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


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

Considering the age of your furnace and the potential of overspending on your heating costs has hopefully offered some perception 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 however, decreased efficiency levels can radically impact your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
