SEER, or Seasonal Energy Efficiency Ratio, is a rating scale that measures an HVAC system's energy efficiency. According to Energy.gov, a SEER rating is a system's cooling output divided by the energy it uses during the warmer part of the year. A higher SEER rating equals a more energy-efficient system. The SEER rating helps homeowners ...
