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

Curious temperature changes and the hope of early spring can let us down as we wait until the end of the cold season. With the erratic weather this time of year, it’s crucial to ensure that your furnace service is taken care of and that your furnace is ready for any weather shift. Part of owning and using a furnace is knowing the system and understanding when it might call for repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to know 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 clarified at your next furnace maintenance appointment from one of our experts at Holiday Heating & Air Conditioning.

So, what does this AFUE rating indicate 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 than with a new furnace each 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 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 given some perception into the significance of your furnace’s AFUE. There are many factors that go into picking a new furnace or staying in your furnace service plan. Over time still, decreased efficiency levels can significantly effect your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and consider it when determining whether it’s time for furnace replacement.
