Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are many variables to contemplate when you purchase 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 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?

Service Experts Heating & Air Conditioning is here to help you understand what the furnace efficiency rating is and the effects is can have on your home and your budget.

The furnace efficiency rating helps calculate how much energy will be needed to heat your home and, essentially, how much it will cost you. Simply put, the higher your furnace efficiency rating the less energy your furnace requires 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 heating system 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 incorrectly installed duct work or attic insulation. The duct work in each home is different – some higher quality, some poorer, so the AFUE rating does not include this in their rating. If you feel that your heating equipment 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 determine how much more energy and money you could possibly save each month.
