Plant was bought in dormant(flowering) stage, but it's summer where I am

[Marbles321]

Hi I have had my plant for about a month now, and it was bought in the dormant (flowering) stage. However, I am located in the Northern California, Sacramento Valley, where it is beginning to become super hot and officially summer. I have read that my Novice Phalaenopsis should be in it's resting stage (growing new leaves, and roots), as it does in it's summer season. I just checked the plant's roots today, which I hadn't known I should've done right when I got it, and cut of a bunch of black dead roots, but there is definitely still some healthy root. Should I repot? or just leave it alone and maybe it will go into a resting stage? Super lost and any information that will save my plant is needed and appreciated!!
