In the U.S., the Department of Energy (DOE) is also concerned about protecting our environment and resources. To address these issues, the DOE recently issued a mandate that now requires all new, central air conditioners manufactured after January 23, 2006, to have a seasonal energy efficiency ratio (SEER) of at least 13. SEER is a number similar to miles-per-gallon in cars; the higher the SEER, the more efficient your air-conditioning system.

According to the DOE, the 13 SEER standard is forecasted to save the nation 4.2 quads (quadrillion British Thermal Units) of energy over 25 years (2006 through 2030). This is equivalent to the energy consumed by nearly 26 million American households in one year. The standards are also expected to save consumers $1 billion over the same period.*

Manufacturers like the Unitary Products Group of York-a Johnson Controls Company, haven’t stopped at 13 SEER. York
