Seasonal Energy Efficiency Ratio

The Seasonal Energy Efficiency Ratio (SEER) measures how efficiently a cooling system, like an air conditioner, operates over an entire cooling season. It’s calculated by dividing the total cooling output (measured in British thermal units, BTUs) by the total electrical energy it consumes (measured in watt-hours). A higher SEER indicates a more efficient system, meaning it provides more cooling for less electricity over the season. SEER helps consumers compare different units and choose energy-efficient options to save on energy costs and reduce environmental impact.
