SEER ratings are dependant on seasonal temperature averages rather than a constant 35 °C (ninety five °F) out of doors temperature. The existing industry minimal SEER ranking is 14 SEER. Engineers have pointed out some areas the place performance of the existing hardware can be enhanced. For example, the admirer blades made use of to move the air usually are stamped from sheet metallic, an economical approach to manufacture, but Due to this fact they are not aerodynamically efficient.
