In recent years, homeowners have become increasingly interested in energy efficiency, and for good reason. Energy audits have become a pretty regular process to help homeowners determine how they can save money through improvements for an energy-saving home.
Among the major energy-consuming appliances in any home are the HVAC systems. As we are edging closer to cold weather, we’ll discuss furnaces here. If you’d like to save money and lower your energy use, then it’s imperative that you have a furnace that can efficiently convert its fuel source into heating power with a minimal amount of energy waste.
Your Furnace’s AFUE Rating
In order to determine how efficient your home’s furnace is, you need to look at its AFUE rating. This number is found on the cabinet or in the user manual, is your system’s “Annual Fuel Utilization Efficiency” measurement, and it informs you of how well your furnace works at converting its fuel source into heating power—whether that is natural gas, electricity, or propane.
AFUE is a total percentage that represents how much of your furnace’s energy source converts into BTUs (British Thermal Units_ of heat. So let’s say your gas furnace on average turns 100 units of natural gas into 85 BTUs. Then the AFUE rating will be 85%. It’s currently required by law that all furnaces have a minimum AFUE rating of 81%. In order to earn the ENERGY STAR label from the U.S. Department of energy, your furnace much have an AFUE of at least 90%. There are high efficiency furnaces out there that rate even higher than this.
In order to ensure that your home’s furnace lives up to its AFUE rating, be sure to contact only professionals for furnace installation, replacement, repairs or maintenance. Our team will make sure that your furnace performs as efficiently as it should for as long as it should.
