Furnace Service, AFUE and What They Mean for You in East Bernard

Curious temperature changes and the expectation of early spring can keep us holding out as we wait until the end of the winter season. With the random weather this time of year, it’s important to double check that your furnace service is complete and that your furnace is prepared for any weather shift. Part of owning and operating a furnace is being familiar with the system and understanding when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to note and can tell you what kind of effectiveness you can expect from your system. If you are unsure of your AFUE, this percentage can be verified at your next furnace tune-up appointment from one of our experts at E B Air Conditioning & Heating Service.

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


  • The older your furnace is, the smaller its AFUE will also be. This means less energy efficiency paralleled to a new furnace in the 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 being used to heat your home.

Considering 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 sticking to your furnace service plan. Over time though, decreased efficiency levels can significantly effect your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and think of it when determining whether it’s time for furnace replacement.
