Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are several factors to contemplate when you invest in a new replacement 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 issues?
  • How big does the system need to be to heat your size of home?

But have you ever thought about your furnace efficiency rating? Are you sure what it means?

Atmostemp Service Experts 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 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 equipment requires 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 used to produce the heat. An example, if your heating system 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 poorly installed duct work or attic insulation. The duct work in each home is different – some high quality, some lower, so the AFUE rating does not consider this in their rating. If you feel that your furnace or duct system is not energy efficient, give your Voorhees installation experts a call today and we will give you a free in-home analysis and help you determine how much more energy and money you could potentially save each month.
