Mini splits that run constantly do not consume more electricity. In fact, they save 58% energy compared to mini splits that do start and stop. The energy efficiency of a start/stop mini split usually is 10 SEER while a mini split that runs constantly is mostly above 20 SEER. The higher the SEER, the better the energy efficiency of the mini split.
The highest SEER rating achieved by a Daikin product is 26.1, and most of the products on their lineup have ratings between 15 and 20. In comparison, most Gree mini split units offer ratings of at least SEER-21, with some products reaching as high as 38.
