Furnace Efficiency Ratings and What They Mean

January 21, 2017

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

 

  • What is your budget for a new furnace?
  • How much are you looking to spend on monthly heating bills?
  • Does anyone living in the home have respiratory ailments?
  • What size system will you need to heat your size of home?

 

But have you ever took into consideration your furnace efficiency rating? Are you sure what it means?

Stevenson Service Experts 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. Essentially, 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 tells you how much heat the furnace will provide compared to the amount of energy used to produce the heat. For example, if your furnace 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 consider the potential heat lost through leaking or incorrectly 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 worry that your heating system or duct system is not energy efficient, give Stevenson 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.
