Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are a lot of variables to contemplate when you purchase a new replacement furnace:

  • What is your budget for a new furnace?
  • How much are you looking to spend on monthly heating bills?
  • Does anyone living in the home have respiratory ailments?
  • Which type and size system do you require 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 you understand 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 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 furnace requires to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the figure that shows how much heat the furnace will supply compared to the amount of energy used to produce the heat. For example, if your furnace has a AFUE rating of 85%, this means 15% of energy used is lost and 85% actually becomes heat for your home.

Note that this rating does not include the potential heat lost through leaking or incorrectly installed duct work or attic insulation. The duct work in each home is different – some higher quality, some lower, so the AFUE rating does not factor this into their rating. If you are concerned that your heating equipment or duct system is not energy efficient, give your Gainesville installation 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 possibly save each month.
