Air-Conditioner Efficiency
When your air-conditioning is on, make certain to shut off kitchen, bath and ventilating fans after they have done their job. In just one hour these fans can blow away a houseful of costly cooled air.
Central air-conditioner efficiency is measured by the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER the more efficient the unit. Units with a SEER of 12 or above are considered high-efficiency; 17 is the highest available.
