Furnace Efficiency Ratings and What They Mean Published on January 21, 2017 There are a lot of variables to think about when you buy a new furnace: How much is your budget for a new furnace?How much can you afford each month in heating bills?Do any of the residents living in the home suffer from respiratory problems?What size system will you need to heat your size of home? But have you ever took into consideration your furnace efficiency rating? Are you sure what it means? Service Experts Heating & Air Conditioning is here to help explain what the furnace efficiency rating is and how it can affect your home and your budget. The furnace efficiency rating helps calculate how much energy you will need to heat your home and, in the long run, how much it will cost you. Basically, the higher your furnace efficiency rating the less energy your furnace needs to heat your home. The AFUE (Annual Fuel Utilization Efficiency) rating is the value that tells you how much heat the furnace will produce compared to the amount of energy used to produce the heat. An example, if your heating system has a AFUE rating of 90%, this means 10% of energy used is lost and 90% actually becomes heat for your home. Remember that this rating does not take into account the potential heat lost through leaking or improperly installed duct work or attic insulation. The duct work in every home is different – some higher quality, some poorer, so the AFUE rating does not factor this into their rating. If you worry that your furnace or duct system is not energy efficient, give Service Experts a call today and we will provide you with a free in-home analysis and help you determine how much more energy and money you could possibly save each month.
