FURNACES / AIR CONDITIONERS
Heating and air conditioning systems are the biggest users of energy in the home, up to 75% of the utility bill. A new high efficiency furnace can save up to 50% in operating costs over a ten year old furnace. Many 1990 and earlier model furnaces have efficiencies of 65% or less. The minimum efficiency furnace that can be sold in the United States today is 78%. Furnaces are available that are up to 94% efficient.
