Confirm that the compressor is running all the time.
You can usually hear it but should also be able to feel it vibrating and it should be warm.

If it is running all the time then it will be an expensive repair as you need a pro.
Often it makes more sense to put those dollars towards a new unit.

It is not uncommon for units to go belly up after a long storage time.

One other thing.
Was the unit tilted at a severe angle or placed on it's side when it was moved?
If yes then you should have let it sit for 24 hours before plugging it in.
If this was the case, unplug it and let it sit. Then give it a try.
