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

Strange temperature changes and the expectation of early spring can mess with us as we wait until the end of winter. With the unpredictable weather this time of year, it’s important to double check that your furnace service is taken care of and that your furnace is ready for any weather swing. Part of owning and operating a furnace is being familiar with 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 know and can disclose to you what kind of productivity you can expect from your system. If you are not informed of your AFUE, this percentage can be verified at your next furnace tune-up appointment from one of our specialists at Franklin's Heating & Air Conditioning, Inc..

So, what does this AFUE rating mean for you? What types of things should you consider with AFUE?


  • The older your furnace is, the lower its AFUE will also be. This means less energy efficiency than with a new furnace every winter when your system is in use.
  • Think about your AFUE percentage with regard 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.

Bearing in mind the age of your furnace and the likelihood of overspending on your heating costs has hopefully provided some insight into the significance of your furnace’s AFUE. There are many factors that go into selecting a new furnace or staying in your furnace service plan. Over time though, decreased efficiency levels can drastically influence your energy usage, monthly bills and coziness. Don’t disregard the AFUE rating of your furnace and reflect on it when deciding whether it’s time for furnace replacement.
