I wish to get rid of these wasps. I am not sure what they are trying to do. Are these wasps creating a hive? Or is there something from the A/C they are collecting to create a hive somewhere else?
They're almost certainly building a nest inside. The condenser provides them an enclosed space for their nest, as well as an ample water source from the condensate.
If you want to get rid of them, buy a wasp spray. They shoot a powerful stream so you can shoot from a distance and typically stun them. The ones inside the unit should evacuate quickly and some may even escape. I've never had them return after spraying.
It would be worth fixing the holes so they cannot return either.
