Heating and air conditioning systems consume significant amounts of energy, up to 75% of a typical residential utility bill. A new high efficiency furnace can help save thousands of dollars in operating costs over the life of the unit when compared to older systems. 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%.

Air Conditioners

The efficiency of an air conditioning unit is determined by its SEER rating (Seasonal Energy Efficiency Ratio). Higher SEER numbers save more money. A 13 SEER rated air conditioner uses 23% less energy then a 10 SEER unit. A 13 SEER rating is the minimum efficiency standard for many Southern California communities.

Heat Pumps

Heat pumps are rated in SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor). SEER and HSPF ratings are like Miles per Gallon rating of automobiles. Higher SEER and HSPF ratings mean greater energy savings.

Fan Coils

The fan coil is the indoor component of a heat pump system. It includes the fan and the heating/cooling coil. The fan coil is designed for a particular refrigerant, so it must match with the heat pump. A variable speed fan coil can improve comfort with improved humidity control, warmer heating temperatures, and save energy while cooling.
