Unfortunately older systems may not have a rating or the information may have been removed.

What is a good efficiency rating for a furnace.

This premier furnace boasts an efficiency rating of up to 99 that means it essentially converts every last bit of energy it uses into heating the home. Most new furnaces display an annual fuel utilization efficiency afue rating which is a measure of fuel efficiency. The fleet efficiency or furnace rating of a particular furnace brand indicates nothing about furnace quality or furnace durability.

In addition although the fleet efficiency of one brand might exceed that of another this does not necessarily indicate that any particular model of furnace marketed under the first brand out performs. A mid efficiency furnace will have an 80 to 85 afue rating while a high energy efficient unit can get up to 90 to 97 afue rating.
