Furnace Efficiency Ratings and What They Mean

January 21, 2017

There are a lot of factors to consider when you invest in a new replacement furnace:

What type of budget do you have for a new furnace?
What can you afford in monthly heating bills?
Do you have anyone in the home with respiratory problems?
Which type and size system do you require to heat your size of home?

But have you ever considered your furnace efficiency rating? Do you understand what it means?

Service Experts Heating & Air Conditioning 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 calculate how much energy will be needed to heat your home and, ultimately, how much it will cost you. Simply put, 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 value that tells you how much heat the furnace will produce compared to the amount of energy used 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.

Note that this rating does not consider 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 substandard, so the AFUE rating does not include this in their rating. If you feel that your furnace or duct system is not energy efficient, give your Melbourne installation experts a call today and we will come out for a free in-home analysis and help you determine how much more energy and money you could possibly save each month.
