Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are several things to think about when you buy a new replacement 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 issues?
  • What size system will you need to heat your size of home?

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

Finch Air Conditioning & Heating is here to help clear up any confusion with 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 you will need to heat your home and, essentially, how much it will cost you. Basically, 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 figure that reflects 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.

Keep in mind 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 higher quality, some poorer, so the AFUE rating does not include this in their rating.
