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

Strange temperature changes and the hope of early spring can let us down as we wait until the end of the winter season. With the erratic weather this time of year, it’s important to make sure that your furnace service is taken care of and that your furnace is set for any weather swing. Part of having and operating 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 a central measurement to recognize and can tell you what kind of productivity you can expect from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace tune-up appointment from one of our specialists at Ken Parker Service Inc.

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


  • The older your furnace is, the smaller its AFUE will also be. This means not as much energy efficiency than with a new furnace in the 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.

Bearing in mind the age of your furnace and the possibility of overspending on your heating costs has hopefully offered some understanding into the weight of your furnace’s AFUE. There are many things that go into selecting a new furnace or sticking to your furnace service plan. Over time still, decreased efficiency levels can radically impact your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and consider it when choosing whether it’s time for furnace replacement.
