Tbh, we probably live in different areas of the US and have different experiences with weather, money, and ac. So this conversation will likely not lead to agreement. Maybe just have sympathy for your roomates, I don’t like going outside after being in a super cold house when it’s hot outside and maybe they are similar. Get them a small space heater or offer to go half’s on it, or just recommend ( and not pay for it) it as a gesture to make compromise
