Could do with a bit of help please have got a Daikin vrv 2 r410a the problem am having is there is a very loud gas noise coming from the pipe work it seems to only happen a couple of hours after change over from heating to cooling. I have noticed the defrost when in heating comes on every 30ish mins which is giving me idea the gas charge is short.

If anyone has any thoughts please feel free to give your opinion just another thought I have a bc box only giving heating and won't switch over to cooling. No fault codes have shown on controllers.
