Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are several variables to think about when you buy a new furnace:

 

  • What type of budget do you have 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?
  • How big does the system need to be to heat your size of home?

 

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

Service Experts Heating & Air Conditioning is here to help clear up any confusion with what the furnace efficiency rating is and how it can affect 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. 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 value that tells you 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 incorrectly installed duct work or attic insulation. The duct work in each home is different – some higher quality, some lower, so the AFUE rating does not factor this into their rating. If you are concerned that your furnace or duct system is not energy efficient, give Service Experts a call today and we will provide you with a free in-home analysis and help you determine how much more energy and money you could be saving each month.
