How AFUE affects your bill

Furnace Service, AFUE and What They Mean for You in Carson City

Interesting temperature changes and the hope 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 vital to ensure that your furnace service is done and that your furnace is ready for any weather shift. Part of having and using a furnace is being familiar with 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 efficiency you can look for from your system. If you are unsure of your AFUE, this percentage can be verified at your next furnace maintenance appointment from one of our specialists at Anderson Heating & A/C.

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 paralleled to a new furnace every winter when your system is in use.
  • Compare your AFUE percentage in relation to money – if your AFUE is 75%, that means that for every $100 you spend on heating your home, only $75 is being used to heat your home.

Bearing in mind the age of your furnace and the likelihood of overspending on your heating costs has hopefully given some understanding into the significance of your furnace’s AFUE. There are many factors that go into picking a new furnace or remaining with your furnace service plan. Over time still, lower 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 choosing whether it’s time for furnace replacement.
