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

Strange temperature changes and the expectation of early spring can mess with us as we wait until the end of winter. With the erratic weather this time of year, it’s vital to double check that your furnace service is done and that your furnace is prepared for any weather change. Part of having and utilizing a furnace is knowing the system and knowing when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to recognize and can disclose to you what kind of efficiency you can look for from your system. If you are unaware of your AFUE, this percentage can be clarified at your next furnace maintenance appointment from one of our professionals at Carefree Heating and Cooling, LLC.

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 smaller its AFUE will also be. This means reduced energy efficiency compared to a new furnace every 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 taken to heat your home.

Taking into account the age of your furnace and the likelihood of overspending on your heating costs has hopefully offered some perception into the significance of your furnace’s AFUE. There are many things that go into choosing a new furnace or remaining with your furnace service plan. Over time though, smaller efficiency levels can radically effect your energy usage, monthly bills and coziness. Don’t disregard the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
