Furnace Efficiency Ratings and What They Mean

January 21, 2017

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

 

  • What is your budget for a new furnace?
  • How much can you afford each month in heating bills?
  • Do any of the residents living in the home suffer from respiratory ailments?
  • What size system will you need to heat your size of home?

 

But have you ever considered your furnace efficiency rating? Do you know what it means?

Norrell Service Experts is here to help explain what the furnace efficiency rating is and what it means for your home and your budget.

The furnace efficiency rating helps determine how much energy will be needed to heat your home and, ultimately, how much it will cost you. Basically, the higher your furnace efficiency rating the less energy your heating equipment requires 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 needed to produce the heat. For instance, if your heating system has a AFUE rating of 90%, this means 10% of energy used is lost and 90% actually becomes heat for your home.

 
 
 
Note that this rating does not consider the potential heat lost through leaking or poorly 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 Norrell Service Experts 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 possibly save each month.
