Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are many variables to consider when you buy 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 considered your furnace efficiency rating? Are you sure what it means?

Wesley Wood Service Experts Heating & Air Conditioning is here to help explain what the furnace efficiency rating is and how it can affect your home and your budget.

The furnace efficiency rating helps establish how much energy is required 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 uses to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the figure that shows how much heat the furnace will produce compared to the amount of energy needed 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 include the potential heat lost through leaking or improperly installed duct work or attic insulation. The duct work in each home is different – some high quality, some poorer, so the AFUE rating does not include this in their rating. If you worry that your heating system or duct system is not energy efficient, give Wesley Wood Service Experts Heating & Air Conditioning a call today and we will come out for a free in-home analysis and help you determine how much more energy and money you could possibly save each month.
