The EnerGuide label is the best tool available to help you select an energy-efficient room air conditioner. Look for the model with a high energy efficiency ratio (EER).

Canada's Energy Efficiency Regulations specify that room air conditioners must carry an EnerGuide label, which helps consumers obtain consistent and reliable information about the relative energy efficiency of room air conditioners for sale in Canada.

The EnerGuide label for room air conditioners looks a lot like the label for appliances, but in fact it is quite different.

• The bold number on the label for room air is known as the EER of the unit. The higher the number, the more energy efficient the model.
• (For the appliance label, the lower the kWh/yr number, the more efficient, because it uses less energy.)

Use the inverted triangle and the graduated bar on the label to compare the performance of a model to others in the same class. Class refers to the type: units with louvred sides are intended for installation in window openings, and are the most common types available today. Units with non-louvred sides are intended for through-the-wall installations. The cooling capacity category is also important and indicated near the bottom of the label.

• The further the triangle is to the right of the scale, the more energy efficient the model.
• (For the appliance label, if the triangle is close to the left, the model is more energy efficient).

To help consumers choose energy-efficient room air conditioners, Natural Resources Canada publishes a directory of models sold in Canada, with their energy ratings. The EnerGuide Room Air Conditioner Directory is available on line, or can be ordered from the Office of Energy Efficiency's virtual library, located at the following web address: http://oee.nrcan.gc.ca/infosource.
