Furnace Efficiency Ratings and What They Mean Published on January 21, 2017 There are several factors to contemplate when you purchase a new furnace: What is your budget for a new furnace?What can you afford in monthly heating bills?Do any of the residents living in the home suffer from respiratory problems?Which type and size system do you require to heat your size of home? But have you ever took into consideration your furnace efficiency rating? Are you sure what it means? Barlow Service Experts Heating & Air Conditioning is here to help you understand 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. Essentially, 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 number that shows how much heat the furnace will produce 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. Keep in mind that this rating does not include the potential heat lost through leaking or poorly installed duct work or attic insulation. The duct work in varying homes is different – some higher quality, some substandard, so the AFUE rating does not factor this into their rating. If you worry that your heating system or duct system is not energy efficient, give Barlow Service Experts a call today and we will come out for a free in-home analysis and help you find out how much more energy and money you could potentially save each month.
