AC pipe covered with ice

AC pipe in the blanket of ice on the pipe in the small and sometimes large pipe to the indoor evaporator to the AC to be filled with ice even less so this will eject ice which causes indoor sound becomes noisy. The cause of ac pipe into ice or commonly called ice blocking the main cause is due to less air conditioning freon, but there are also other factors that may cause the ac pipes freeze, do not rule out the possibility of ice on the AC pipe will spread to the indoor (evaporator) other causes making ac be like this among them are: 
1 large pipe * low pressure * on the outdoor twisted, kinked so little space for this refrigerant circulates, this is usually caused inadvertent ac technician tighten the nipple during outdoor (too tight) 
2. bend pipes from indoor to outdoor bent, squashed caused during the installation of the AC bending too sharply, if it is difficult to bend elblow just use an air conditioner especially for the above 2PK and do welding on pipe ac, but ac installation process becomes very longer than usual 

The fix: 
1 Turn off the AC 
2 Flush with water contained in the ice floes in the indoor evaporator until the ice melts. 
3 Turn on the AC and then Close the faucet in the outdoor (pump down), so that the freon is not wasted. 
4 Cut the pipe is twisted, flarring reset and reconnect with Las tool. 
5. Install the air conditioner pipes, and in the vacuum. 
6 Fill Freon air conditioner back if freonnya less pressure. If there are signs of AC pipes into ice immediately handled seriously do not let it go on because it can result in the compressor will be damaged too long can be broken compressor.
