Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are several variables to think about when you buy a new 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?
  • How big does the system need to be to heat your size of home?

 

But have you ever took into consideration your furnace efficiency rating? Do you know what it means?

Donelson Air Service Experts is here to help clear up any confusion with 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 value that reflects how much heat the furnace will supply compared to the amount of energy required to produce the heat. An example, if your heating equipment 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 include the potential heat lost through leaking or improperly installed duct work or attic insulation. The duct work in varying homes is different – some high quality, some substandard, so the AFUE rating does not consider this in their rating. If you are concerned that your furnace or duct system is not energy efficient, give Donelson Air Service Experts a call today and we will provide you with a free in-home analysis and help you find out how much more energy and money you could be saving each month.
