Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are several variables to consider when you purchase 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 issues?
  • What size system will you need 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, ultimately, how much it will cost you. Basically, the higher your furnace efficiency rating the less energy your heating equipment requires to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the figure that tells you how much heat the furnace will supply 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 consider the potential heat lost through leaking or incorrectly installed duct work or attic insulation. The duct work in varying homes is different – some high quality, some poorer, so the AFUE rating does not factor this into their rating.
