Choosing a New Furnace – What is AFUE

choosing a new furnaceWhen it’s time to replace your furnace, you will be replacing it with a newer model that is more cost effective. High efficiency furnaces will have an AFUE rating of over 80 and can save you money on heating your home. When choosing a new furnace, your technician from Greater Comfort Heating and Air Conditioning can advise you one the best model and product you need.

What is AFUE

The AFUE (Annual Fuel Utilization Efficiency) is a Department of Energy number rating system that tells how energy efficient your new furnace or broiler is. The numbers range from 1-100 and the higher the number the better. As of May 2013 all new furnaces in the United States have to have an AFUE of at least 80. The AFUE number is actually a percentage that tells you how much of the energy is being used by your system and how much is wasted. If your furnace has an AFUE of 80, then 80% of the fuel is being used and 20% is wasted. That is like saying for every dollar you spend heating your home, 20 cents is tossed out the window.

Should I Replace An Older Furnace

Normally you do not need to replace your older furnace before it is time because of a lower AFUE. When your furnace is no longer working properly or is requiring furnace repair often, you should begin to think about a new replacement. If you have questions about replacing your furnace, ask your technician during your home maintenance and they can give you some answers. AFUE ratings also refer only to the furnace or broiler itself. If you truly want to reach maximum efficiency, you will need to also have your duct work sealed and other components working at their peak efficiency.
