- Central air conditioning systems distribute cool air throughout a home with the aid of a duct system. Energy-efficient models are certified by the ENERGY STAR program, a joint effort of the United States Environmental Protection Agency and the Department of Energy. These models must meet higher efficiency standards than normal central air units.
- According to ENERGY STAR, an energy-efficient central air conditioner may cost up to 30 percent less to operate than non-energy-efficient models. Additionally, energy-efficient units produce fewer greenhouse gas emissions, making them environmentally friendly. Tax credits and rebates may also be available for certified products.
- According to ENERGY STAR, certified central air conditioning units are 14 percent more efficient than standard models due to the fact that their seasonal efficiency energy ratios (SEER) and energy efficiency ratios (EER) are much higher.
