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

Curious temperature changes and the desire for early spring can let us down as we wait until the end of the winter season. With the random weather this time of year, it’s important to make sure that your furnace service is complete and that your furnace is set for any weather shift. Part of having and utilizing a furnace is knowing the system and knowing when it might need repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a significant measurement to recognize and can tell you what kind of efficiency you can look for from your system. If you are unaware of your AFUE, this percentage can be verified at your next furnace tune-up appointment from one of our professionals at Rescue Heating & Air .

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


  • The older your furnace is, the lower its AFUE will also be. This means not as much energy efficiency than with a new furnace each winter when your system is in use.
  • Compare your AFUE percentage proportionate to money – if your AFUE is 75%, that means that for every $100 you devote to heating your home, only $75 is spent to heat your home.

Considering the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some insight into the weight of your furnace’s AFUE. There are many elements that go into choosing a new furnace or sticking to your furnace service plan. Over time though, smaller efficiency levels can radically effect your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and reflect on it when deciding whether it’s time for furnace replacement.
