Temp in baby's room

my son sleeps better in a darken room but with the weather being so hot im worried it may be too hot in his room. we have the temp gage built in to the baby monitor so by his crib is 80 i have a fan in his window but its just blowing hot air around. should i put him in his pack in play downstairs where its cooler or will he be ok in his crib

    We bought a window air conditioner unit for the nursery. Most of the time it's set just so it circulates air, but there are sometimes where we use the ac part.
