The condenser replacement shouldn't have required pulling the IC or anything to my knowledge. The Tech manual for the car confirms this. However, was there a software update on your ECU while you were there? I have noticed my car act funny after there's been an update, but after a day or two of driving its usually back to normal. This is usually done as a "TSB" which is like a Hyundai internal way of fixing things before they become a mandated recall, or just making something the way it should have been from the factory.
