seerchartLet First Coast Air help you understand how an improved SEER rating can help you save money.

Definition

SEER is an acronym for seasonal energy efficiency rating. The United States and Canada use the SEER to determine the energy efficiency of air conditioning units. Many organizations, including the federal Energy Star program and local power companies, use SEER numbers when awarding installation rebates.

Calculations

Industrial air conditioners must be efficient to be cost effective.

Manufacturers, power companies, and federal departments calculate the SEER by dividing the thermal output of the air conditioning unit (measured in Btu) by the total watt hours of energy the unit consumed. This is measured over an average cooling season. Energy-efficient units have higher SEER numbers than standard units.

 

Efficiency

Old air conditioners consume much more energy than new models.

According to the U.S. Department of Energy website, 13 is the lowest SEER rating allowed in new residential air conditioning units as of January 23, 2006. Earlier models may have SEER numbers as low as 6, increasing power costs for the homeowner. Since air conditioning units may last 15 to 20 years, replacing an inefficient air conditioner saves the homeowner money in future energy costs. If your current unit is 10 years old, replacing it with a new unit may cut 20 to 40 percent off your power bill.
