Furnace Service, AFUE and What They Mean for You in McHenry12/31/2015 Strange temperature changes and the desire for early spring can mess with us as we wait until the end of winter. With the unpredictable weather this time of year, it’s vital to ensure that your furnace service is done and that your furnace is set for any weather swing. Part of owning and operating a furnace is knowing the system and preparing for when it might call for 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 effectiveness you can expect from your system. If you are unsure of your AFUE, this percentage can be clarified at your next furnace service appointment from one of our specialists at Jett's Heating & Air Inc.. So, what does this AFUE rating indicate for you? What sorts of things should you take into account with AFUE? The older your furnace is, the lower its AFUE will also be. This means less energy efficiency than with a new furnace in the winter when your system is in use. Compare your AFUE percentage with regard to money – if your AFUE is 75%, that means that for every $100 you devote to heating your home, only $75 is being used to heat your home. Bearing in mind the age of your furnace and the possibility of overspending on your heating costs has hopefully provided some understanding into the weight of your furnace’s AFUE. There are many factors that go into picking a new furnace or sticking to your furnace service plan. Over time still, lower efficiency levels can drastically impact your energy usage, monthly bills and comfort. Don’t overlook the AFUE rating of your furnace and reflect on it when deciding whether it’s time for furnace replacement.
