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

Interesting temperature changes and the expectation of early spring can mess with us as we wait until the end of winter. With the erratic weather this time of year, it’s vital to make sure that your furnace service is done 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 require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is a central measurement to recognize and can disclose to you what kind of productivity you can anticipate from your system. If you are not informed of your AFUE, this percentage can be clarified at your next furnace tune-up appointment from one of our specialists at Cool Power LLC .

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


  • The older your furnace is, the lower its AFUE will also be. This means reduced energy efficiency compared to a new furnace every winter when your system is in use.
  • Think about your AFUE percentage proportionate to money – if your AFUE is 75%, that means that for every $100 you use heating your home, only $75 is spent to heat your home.

Considering the age of your furnace and the potential of overspending on your heating costs has hopefully given some understanding into the importance of your furnace’s AFUE. There are many things that go into selecting a new furnace or remaining with your furnace service plan. Over time however, decreased efficiency levels can radically impact your energy usage, monthly bills and coziness. Don’t ignore the AFUE rating of your furnace and reflect on it when choosing whether it’s time for furnace replacement.
