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

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 unpredictable 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 owning and utilizing a furnace is being familiar with the system and preparing for when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to recognize and can disclose to you what kind of productivity you can anticipate from your system. If you are unsure of your AFUE, this percentage can be determined at your next furnace service appointment from one of our experts at Bishop Heating & Air Conditioning.

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 littler its AFUE will also be. This means reduced energy efficiency paralleled to a new furnace every winter when your system is in use.
  • Compare 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.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully offered some understanding into the significance of your furnace’s AFUE. There are many factors that go into choosing a new furnace or remaining with your furnace service plan. Over time however, smaller efficiency levels can radically impact your energy usage, monthly bills and comfort. Don’t disregard the AFUE rating of your furnace and reflect on it when choosing whether it’s time for furnace replacement.
