Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are several variables to think about when you invest in a new replacement furnace:

  • How much is your budget for a new furnace?
  • How much are you looking to spend on monthly heating bills?
  • Do you have anyone in the home with respiratory ailments?
  • 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? Do you understand what it means?

San Antonio Air Service Experts 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 determine how much energy you will need to heat your home and, in the long run, how much it will cost you. Essentially, the higher your furnace efficiency rating the less energy your heating equipment uses to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the number that tells you how much heat the furnace will provide compared to the amount of energy needed to produce the heat. An example, if your heating system has a AFUE rating of 85%, this means 15% of energy used is lost and 85% actually becomes heat for your home.

Remember that this rating does not consider the potential heat lost through leaking or poorly installed duct work or attic insulation. The duct work in every home is different – some higher quality, some substandard, so the AFUE rating does not consider this in their rating. If you worry that your furnace or duct system is not energy efficient, give your San Antonio 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 be saving each month.
