How AFUE affects your bill

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

Interesting temperature changes and the expectation of early spring can keep us holding out as we wait until the end of winter. With the random 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 swing. Part of having and using a furnace is knowing the system and knowing when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to note and can tell you what kind of productivity you can look for from your system. If you are unaware of your AFUE, this percentage can be verified at your next furnace maintenance appointment from one of our specialists at Main Heating & Cooling, Inc..

So, what does this AFUE rating suggest for you? What types of things should you think on with AFUE?


  • The older your furnace is, the lower its AFUE will also be. This means reduced energy efficiency paralleled to a new furnace each winter when your system is in use.
  • Think about your AFUE percentage in relation to money – if your AFUE is 75%, that means that for every $100 you use heating your home, only $75 is taken to heat your home.

Taking into account the age of your furnace and the possibility of overspending on your heating costs has hopefully offered some perception into the significance of your furnace’s AFUE. There are many elements that go into selecting a new furnace or staying in your furnace service plan. Over time however, lower efficiency levels can drastically impact your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and reflect on it when determining whether it’s time for furnace replacement.
