How AFUE affects your bill

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

Strange 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 crucial to ensure that your furnace service is taken care of and that your furnace is prepared for any weather shift. Part of having and utilizing a furnace is understanding 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 note 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 service appointment from one of our experts at Quality Refrigeration.

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


  • The older your furnace is, the smaller its AFUE will also be. This means reduced energy efficiency compared to a new furnace in the winter when your system is in use.
  • Consider your AFUE percentage proportionate 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.

Considering the age of your furnace and the potential of overspending on your heating costs has hopefully provided some perception into the importance of your furnace’s AFUE. There are many elements that go into picking a new furnace or sticking to your furnace service plan. Over time still, smaller efficiency levels can significantly effect your energy usage, monthly bills and coziness. Don’t overlook the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
