Split AC removal

Looking for advice regarding the removal of a split type air conditioner. I have read online that you can trap the gas inside the outside unit by closing the smaller outlet valve and then turning on the AC until you hear the compressor stop running.
I've done this but I haven't noticed any changes in sound at all. How long is enough to ensure all the gas is out of the pipes? I let it run for about five minutes. I've left the inlet valve open for now.

Thanks all.

We are not allowed to help when it comes to the refrigerant part of the system. For your safety don't run the compressor till it stops.

There are many ways of doing this.
You'll need a gauge manifold and refrigerant certification

No problem.
Do you think the way I have left it (inlet open and outlet closed) is unsafe? What will have happen if compressor stops?
Should I just get someone in to do it as too risky for DIY?

Thanks.

You can't just wait till the compressor stops. It may not, and just keep running.
Dealing with refrigerant is a bit beyond diy work.

Yes.... you should have the refrigerant removed for the system by a pro.

Okay, thanks for the sage advice. Also realised proper disposal of units not possibly (in Ireland) without certificate so not worth going to the trouble of taking them out.
I've called an expert to sort it out.

Cheers all.
