Furnace Efficiency Ratings and What They Mean

January 21, 2017

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

  • What is your budget for a new furnace?
  • What can you afford in monthly heating bills?
  • Do you have anyone in the home with 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? Do you know what it means?

Service Experts Heating & Air Conditioning is here to help explain what the furnace efficiency rating is and what it means for your home and your budget.

The furnace efficiency rating helps calculate how much energy is required to heat your home and, essentially, how much it will cost you. Essentially, 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 produce compared to the amount of energy needed to produce the heat. For instance, 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.

Keep in mind that this rating does not include the potential heat lost through leaking or incorrectly installed duct work or attic insulation. The duct work in every home is different – some higher 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 Denver 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.
