What is a SEER rating


Like any other appliance or electronic, AC units have a rating system. The SEER system stands for Seasonal Energy Efficiency Ratio because it tells the consumer how energy efficient their unit is. The higher the SEER rating, the more energy efficient the unit is and the lower the operating cost.
