SEER ratings are dependant on seasonal temperature averages in place of a constant 35 °C (95 °File) outside temperature. The existing market minimum SEER score is fourteen SEER. Engineers have identified some locations wherever efficiency of the existing components could be improved. Such as, the enthusiast blades utilised to maneuver the air are often stamped from sheet metal, a cheap means of manufacture, but as a result they aren't aerodynamically successful. A perfectly-developed blade could reduce the electrical electricity necessary to go the air by a 3rd.[40]
