Furnace Efficiency Ratings and What They Mean Published on January 21, 2017 There are many factors to contemplate when you purchase a new furnace: What type of budget do you have for a new furnace?How much can you afford each month in heating bills?Do you have anyone in the home with respiratory issues?How big does the system need to be to heat your size of home? But have you ever thought about your furnace efficiency rating? Do you know what it means? Service Experts Heating & Air Conditioning is here to help clear up any confusion with what the furnace efficiency rating is and the effects is can have on your home and your budget. The furnace efficiency rating helps determine how much energy will be needed to heat your home and, ultimately, how much it will cost you. Essentially, the higher your furnace efficiency rating the less energy your heating system needs to heat your home. The AFUE (Annual Fuel Utilization Efficiency) rating is the figure that reflects how much heat the furnace will provide compared to the amount of energy required to produce the heat. For example, if your heating system has a AFUE rating of 80%, this means 20% of energy used is lost and 80% actually becomes heat for your home. Remember 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 good quality, some substandard, so the AFUE rating does not factor this into their rating. If you are concerned that your heating system or duct system is not energy efficient, give Service Experts a call today and we will come out for a free in-home analysis and help you discover how much more energy and money you could possibly save each month.
