Furnace Efficiency Ratings and What They Mean

January 21, 2017

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

 

  • What is your budget for a new furnace?
  • What can you afford in monthly heating bills?
  • Do you have anyone in the home with respiratory ailments?
  • 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?

Midland Air 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. 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 provide compared to the amount of energy needed to produce the heat. For 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.

 
 
 
Note that this rating does not consider the potential heat lost through leaking or incorrectly installed duct work or attic insulation. The duct work in varying homes is different – some higher quality, some lower, so the AFUE rating does not factor this into their rating. If you worry that your heating equipment or duct system is not energy efficient, give Midland Air Service Experts a call today and we will provide you with a free in-home analysis and help you find out how much more energy and money you could potentially save each month.
