January 21, 2017

There are several variables to contemplate when you invest in a new replacement furnace:

  • What is your budget for a new furnace?
  • What can you afford in monthly heating bills?
  • Does anyone living in the home have respiratory ailments?
  • Which type and size system do you require to heat your size of home?

But have you ever took into consideration your furnace efficiency rating? Are you sure what it means?

Service Experts Heating & Air Conditioning is here to help clear up any confusion with what the furnace efficiency rating is and how it can affect 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. Basically, the higher your furnace efficiency rating the less energy your heating equipment uses to heat your home.

The AFUE (Annual Fuel Utilization Efficiency) rating is the value that shows how much heat the furnace will produce compared to the amount of energy used to produce the heat. For instance, 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 include the potential heat lost through leaking or incorrectly installed duct work or attic insulation. The duct work in varying homes is different – some high quality, some lower, so the AFUE rating does not factor this into their rating.
