What tell me the SEER of a Mini Split?
Seer is a coefficient that measures energy efficiency. The more kW they are generated by each KW consumed, the more efficient a team is. A SEER 2.0 would indicate that the system is capable of producing 2 kW of cold energy for each kW of energy spent.
This translates into practice as follows: The higher the SEER, the more efficient the cooling system should be.
