AFUE is the standard measurement of efficiency for gas and oil-fired furnaces. Given in percentages, this number tells you how much of your fuel is used to heat your home and how much fuel is wasted. The higher the AFUE rating, the greater the efficiency. AC Unit Direct offers a full line of furnaces with AFUE ratings ranging from the minimum industry requirement of 78% to more than 96%.
