Furnace Efficiency Ratings and What They Mean

January 21, 2017

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

 

  • What is your budget for a new furnace?
  • How much are you looking to spend on monthly heating bills?
  • Do any of the residents living in the home suffer from respiratory problems?
  • What size system will you need to heat your size of home?

 

But have you ever thought about your furnace efficiency rating? Are you sure what it means?

Service Experts Commercial HVAC 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 determine how much energy you will need to heat your home and, essentially, how much it will cost you. Basically, 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 reflects how much heat the furnace will supply compared to the amount of energy required to produce the heat. An example, if your furnace has a AFUE rating of 85%, this means 15% of energy used is lost and 85% actually becomes heat for your home.

 
 
 
Keep in mind 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 varying homes is different – some high quality, some lower, so the AFUE rating does not consider this in their rating. If you feel that your heating equipment or duct system is not energy efficient, give Service Experts Commercial HVAC a call today and we will give you a free in-home analysis and help you discover how much more energy and money you could be saving each month.
