I think the problem you may run into is the refrigerant. The units probably came already filled. When the units were installed, a valve was opened and all the refrigerant went into the piping and the inside unit. When you disconnect everything all that refrigerant will disappear into the air. Around here you might get a HVAC guy to pump the refrigerant out and reuse it whereever you are moving to. where you are, I doubt it. And you will need to have someone add refrigerant at the new location.

I would say, you should first have a professional inspection. Since, as you told that the guys who installed these AC's did not seem like actual technicians, it may be that they could have made some mistakes there.

Thanks for your replies!

I had a professional come take a look and he said it was okay.

Yea, replacing the refrigerant would cost me a bit.

Some of them here actually do pump the refrigerant out before removing the units.
