What’s a SEER ratio? The U.S. Department of Energy defines SEER as the Seasonal Energy Efficiency Ratio, or the measure of the energy efficiency of a heating and cooling system. Minimum standards are set by the DOE, depending on geographical region. To calculate a SEER ratio, DOE simulates a “typical” cooling season of a region, and compares outdoor temperatures (from 60 degrees to over 100) to a constant indoor temperature. Then, they divide that number by energy usage in Watt-Hours. The total is the...
