Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are a lot of factors to think about when you buy a new furnace:

 

  • How much is your budget for a new furnace?
  • What can you afford in 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 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 what it means for your home and your budget.

The furnace efficiency rating helps establish how much energy is required to heat your home and, essentially, how much it will cost you. Simply put, the higher your furnace efficiency rating the less energy your heating system 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 required to produce the heat. An 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 take into account the potential heat lost through leaking or improperly installed duct work or attic insulation. The duct work in each home is different – some good quality, some lower, so the AFUE rating does not consider 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 provide you with a free in-home analysis and help you discover how much more energy and money you could possibly save each month.
