Baby Room temperature

Anyone else stress the temperature in their kiddos room and what they dress them in???? My little one is 15 months. He is usually running on the warmer side. Our upstairs right now reads 80! So I put him in short sleeve jammies (pants) and no sleep sack with his windows open and fan on. My hubs thinks I over-stress it. If it gets cool knowing he doesn’t have a sleep sack on I can always turn fan off. Just want some advice here lol. Thanks ladies!!!!
