Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are many things to consider when you buy a new furnace:

 

  • How much is your budget for a new furnace?
  • What can you afford in monthly heating bills?
  • Do you have anyone in the home with respiratory problems?
  • How big does the system need to be to heat your size of home?

 

But have you ever considered your furnace efficiency rating? Are you sure what it means?

Roland J. Down Service Experts Heating & Air Conditioning is here to help clear up any confusion with what the furnace efficiency rating is and what it means for your home and your budget.

The furnace efficiency rating helps calculate 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 requires to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the figure that shows how much heat the furnace will provide compared to the amount of energy needed to produce the heat. For example, if your heating equipment has a AFUE rating of 80%, this means 20% of energy used is lost and 80% actually becomes heat for your home.

 
 
 
Note that this rating does not include the potential heat lost through leaking or poorly installed duct work or attic insulation. The duct work in each home is different – some higher quality, some lower, so the AFUE rating does not consider this in their rating. If you feel that your heating system or duct system is not energy efficient, give Roland J. Down Service Experts Heating & Air Conditioning 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 potentially save each month.
