Seasonal Energy Efficiency Ratio (SEER). Overall, the SEER offers you an overview of the air conditioning system's seasonal average efficiency.
The electricity is necessary to run the compressor, condenser fan, and the internal blower motor is included.
The SEER is a measure of how much energy a system consumes. The greater the SEER, the less energy it uses.
Energy Efficiency Ratio (EER) defines how efficient your air conditioner is. The higher and better EER, the efficient your air conditioner is.
