Furnace Efficiency Ratings and What They Mean

January 21, 2017

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

  • How much is your budget for a new furnace?
  • How much can you afford each month in 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 considered 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 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, essentially, how much it will cost you. Basically, 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 value that shows how much heat the furnace will provide compared to the amount of energy required to produce the heat. An 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.

Keep in mind that this rating does not consider 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 poorer, so the AFUE rating does not consider this in their rating.
