Furnace Efficiency Ratings and What They Mean Published on January 21, 2017 There are several things to think about when you invest in a new furnace: What is your budget for a new furnace?How much are you looking to spend on monthly heating bills?Do any of the residents living in the home suffer from respiratory issues?How big does the system need to be to heat your size of home? But have you ever took into consideration your furnace efficiency rating? Do you know what it means? Service Experts Heating & Air Conditioning is here to help explain what the furnace efficiency rating is and what it means for your home and your budget. The furnace efficiency rating helps determine how much energy you will need to heat your home and, ultimately, how much it will cost you. Simply put, the higher your furnace efficiency rating the less energy your heating equipment needs to heat your home. The AFUE (Annual Fuel Utilization Efficiency) rating is the figure that tells you how much heat the furnace will supply compared to the amount of energy used to produce the heat. An example, if your heating equipment has a AFUE rating of 90%, this means 10% of energy used is lost and 90% actually becomes heat for your home. Keep in mind that this rating does not include the potential heat lost through leaking or incorrectly installed duct work or attic insulation. The duct work in every home is different – some higher quality, some lower, so the AFUE rating does not consider this in their rating.
