Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are several variables to think about when you purchase a new furnace:

 

  • What 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 thought about your furnace efficiency rating? Do you know what it means?

Service Experts Heating & Air Conditioning is here to help clear up any confusion with 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 is required to heat your home and, in the long run, how much it will cost you. Basically, the higher your furnace efficiency rating the less energy your furnace uses to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the figure that reflects how much heat the furnace will provide 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 take into account 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 lower, so the AFUE rating does not include this in their rating. If you worry that your furnace or duct system is not energy efficient, give Service Experts a call today and we will give you a free in-home analysis and help you discover how much more energy and money you could be saving each month.
