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

Interesting temperature changes and the desire for early spring can keep us holding out as we wait until the end of the winter season. 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 prepared for any weather change. Part of having and operating a furnace is knowing the system and preparing for when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to recognize and can tell you what kind of effectiveness you can expect from your system. If you are not informed of your AFUE, this percentage can be verified at your next furnace service appointment from one of our specialists at Arrings A/C & Heating.

So, what does this AFUE rating mean for you? What kinds of things should you consider 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 in relation 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.

Considering the age of your furnace and the likelihood of overspending on your heating costs has hopefully given some perception into the weight of your furnace’s AFUE. There are many things that go into choosing a new furnace or sticking to your furnace service plan. Over time still, decreased 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.
