Furnace Efficiency Ratings and What They Mean

January 21, 2017

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

 

  • How much is your budget for a new furnace?
  • What can you afford in 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 took into consideration your furnace efficiency rating? Do you know what it means?

Service Experts Heating & Air Conditioning is here to help explain what the furnace efficiency rating is and how it can affect your home and your budget.

The furnace efficiency rating helps calculate how much energy is required to heat your home and, in the long run, how much it will cost you. Simply put, the higher your furnace efficiency rating the less energy your heating system needs to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the number that shows how much heat the furnace will supply compared to the amount of energy used to produce the heat. An example, if your furnace has a AFUE rating of 90%, this means 10% of energy used is lost and 90% actually becomes heat for your home.

Remember that this rating does not take into account the potential heat lost through leaking or poorly 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 consider this in their rating. If you worry that your heating system 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 be saving each month.
