We have a problem with our airconditioner it is a Hitachi although it is an old one it works fine when it works.
Our problem when we activate the airconditioning the compressor makes a terrible noise. We had 2 times a mecanic looking at the system but none solved the problem one thought the Neutral was loose or made a bad connection and the other added 1,5 litre of oil into the system. The problem stays and comes and goes. I now found out when the noise commenses and i switch the remote control on the wall from cooling to heating and directly again to cooling it works fine and we don't have any problems for the whole day. For me it sounds like a valve which isn't working well but again I am not a specialist in airconditioning. Can anybody give me some advise? It is a Hitachi on the outside unit on the unit it says something with a UzuQ but the type isn't readable. It is a system 380V I think moreless 20 years old.
Please help
