Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are many variables to consider when you invest in 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 any of the residents living in the home suffer from respiratory problems?
  • 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?

All American Air Service Experts is here to help you understand 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 system 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 needed to produce the heat. An example, if your furnace has a AFUE rating of 80%, this means 20% of energy used is lost and 80% 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 varying homes is different – some high quality, some poorer, so the AFUE rating does not include this in their rating. If you worry that your furnace or duct system is not energy efficient, give your Daytona Beach installation experts a call today and we will come out for a free in-home analysis and help you discover how much more energy and money you could potentially save each month.
