Proper installation involves the mandatory installation of the visor above the compressor of the air conditioner. He will save the external block from rain and snow. If the air conditioner is supposed to be installed on high floors, they call climbers (the price of their services is from 60 to $ 150). Living on the last floors can install the outer part of the split systems directly on the roof, but so that the difference between the height of the “street” and the inner block is small (not more than 3 meters).
