Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are a lot of factors to consider 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 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 considered your furnace efficiency rating? Are you sure what it means?

Service Experts Heating & Air Conditioning 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 establish how much energy will be needed to heat your home and, ultimately, how much it will cost you. Simply put, the higher your furnace efficiency rating the less energy your furnace uses to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the number that tells you 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.

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 each home is different – some higher quality, some lower, so the AFUE rating does not include this in their rating. If you are concerned that your heating system 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 potentially save each month.
