@karlonavarro besides needing a new plug for your Air Conditioner you would also be better of finding a different circuit to plug it into. This "due to my aircon plug heating" is more unsafe then installing a new plug. Your AC is drawing to many amps for the circuit it is plugged into. Have the electrician take a look at that for sure.
There are really no universal plugs just standard plugs. We will need to see what yours look like so we could tell you what you need. Yes, it is safe to replace the plug on your AC if done right.
