Furnace Service, AFUE and What They Mean for You in the Main Line12/31/2015 Strange temperature changes and the desire for early spring can let us down as we wait until the end of winter. With the random weather this time of year, it’s important to double check that your furnace service is taken care of and that your furnace is set for any weather shift. Part of having and utilizing a furnace is understanding the system and knowing when it might require repair or maintenance. A furnace’s AFUE (Annual Furnace Utilization Efficiency) is an important measurement to know and can disclose to you what kind of effectiveness 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 professionals at O'Brien Heating & Air Conditioning. So, what does this AFUE rating suggest for you? What types of things should you take into account with AFUE? The older your furnace is, the smaller its AFUE will also be. This means reduced energy efficiency than with a new furnace in the winter when your system is in use. Consider 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 being used to heat your home. Considering the age of your furnace and the potential of overspending on your heating costs has hopefully provided some perception into the significance of your furnace’s AFUE. There are many things that go into choosing a new furnace or remaining with your furnace service plan. Over time however, lower efficiency levels can drastically impact your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and consider it when deciding whether it’s time for furnace replacement.
