Product Energy Rating Definitions ecoLogic - Frigidaire's designation of green heating and cooling products Only the most energy-efficient, most environmentally responsible units qualify for the ecoLogic seal. SEER Seasonal Energy Efficiency Rating Measures cooling performance on air conditioners, heat pumps and gas/electric package products. HSPF Heating Seasonal Performance Factor Is a measure of the average number of BTU’s of heat delivered for every Watt-hour of electricity used by the heat pump over the heating season. AFUE Annual Fuel Utilization Efficiency It measures the amount of heat actually delivered to your house compared to the amount of fuel that you supply to the furnace. Thus, a furnace that has an 80% AFUE rating converts 80% of the fuel that you supply to heat - the other 20% is lost out of the chimney. As ratings increase, so does unit efficiency. |
