A, If you added an extra three metres to your AC unit duct and did not increase the diameter, the motor in the AC unit would not be able to expel the hot air fast enough and would overheat...Q, Why is the hose supplied more flexible that the original Duct that came with the AC Unit? A, Adding three metres of Duct with the same tough semi rigid plastic pipe supplied would be heavy and also in most cases difficult to position. The added flexability allows for light weight easy placment where you  most need the cooler. Q, Doesnt the think PVC tube supplied just get hot and reheat the room?
