I am considering replacing our forced air NG furnace Heil model cugi100af01 I believe it is a 100,000 btu input and 75,000 btu output furnace with a variable speed motor. It is operating fine but i am wondering if a high ef unit would be warranted. DoesPost created: 2012-08-04 Type of Equipment: Furnace Views: 295

Does anyone know the EF rating on this furnace? If it is 60% Ef then replacement is practical.
