Furnace Efficiency Ratings and What They Mean

January 21, 2017

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

 

  • How much is your budget for a new furnace?
  • How much can you afford each month in heating bills?
  • Does anyone living in the home have 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? Are you sure what it means?

Donelson Air Service Experts 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 establish how much energy you will need to heat your home and, in the long run, how much it will cost you. Simply put, 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 number that reflects how much heat the furnace will produce 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 factor this into their rating. If you feel that your furnace or duct system is not energy efficient, give Donelson Air Service Experts a call today and we will give you a free in-home analysis and help you find out how much more energy and money you could be saving each month.
