There can be some stress to plants following repotting.
Make sure that you used a well draining commercial potting soil and pot size was chosen that comfortably held the roots with just an inch extra space.
To large of a container will lead to root rot.
Check the soil before watering. Make sure the top inch or so has dried before watering again.
Chinese Evergreen will also turn yellow if they are too cold.
