Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are a lot of things to think about when you purchase a new furnace:

 

  • What 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?
  • How big does the system need to be to heat your size of home?

 

But have you ever thought about your furnace efficiency rating? Do you understand what it means?

McElroy Service Experts Heating & Air Conditioning is here to help explain what the furnace efficiency rating is and the effects is can have on 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. Essentially, the higher your furnace efficiency rating the less energy your furnace needs to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the figure that shows how much heat the furnace will supply compared to the amount of energy needed to produce the heat. An 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.

 
 
 
Remember 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 high quality, some poorer, so the AFUE rating does not include this in their rating. If you are concerned that your heating equipment or duct system is not energy efficient, give McElroy 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 possibly save each month.
