The (EER) or Energy Efficiency Ratio measures the efficiency of an air conditioner by calculating the ratio of its cooling capacity in BTU per hour to the power input in watts.

Air conditioners tend to consume the most energy in a household, especially in regions with hot climates.

The (Energy Star) label is a government-backed symbol that helps consumers identify energy-efficient products, including appliances.

While insulation thickness, door seal effectiveness, and compressor efficiency all impact energy efficiency, the automatic defrost feature does not directly contribute to it.

Energy-efficient appliances primarily help reduce energy consumption and consequently lower energy bills for consumers.

Energy-efficient washing machines are designed to conserve water and reduce energy consumption, not increase water usage.

The (EnergyGuide) label is designed to inform consumers about the estimated energy consumption and operating costs of an appliance.

Energy-efficient dishwashers typically aim to reduce water consumption, not increase it.

The efficiency of an air conditioner is largely determined by the efficiency of its compressor.

Leaving appliances on standby mode consumes energy even when they are not in use, which is not an energy-efficient practice.

Energy-efficient light bulbs are designed to consume less energy while providing the same or better light output.

Energy-efficient ovens are designed to reduce energy consumption, not increase it.

The (ENERGY STAR) program primarily aims to promote energy-efficient products and practices.

Energy-efficient appliances in commercial buildings are designed to reduce energy consumption, not increase it.

The energy consumption rating is a crucial factor to consider when choosing an energy-efficient appliance.
