Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are a lot of things to consider when you buy a new furnace:

 

  • What type of budget do you have for a new furnace?
  • What can you afford in monthly 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 thought about your furnace efficiency rating? Do you understand what it means?

McElroy Service Experts 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 determine 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 tells you how much heat the furnace will supply compared to the amount of energy required to produce the heat. An example, if your heating equipment has a AFUE rating of 85%, this means 15% of energy used is lost and 85% 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 lower, 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 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.
