My brother does not supply HVAC

I do not like when I get stuck spending the night at our brothers, and about once every 2 weeks our brother and I go out to the bars, then the two of us don’t gathering too much, so we spend the night after a bar day, but if we do the bars near our place, our brother crashes with me, however most of the time though, we go to his section and I end up in his additional room. My brother has an amazing house, big backyard and a pool. The reason I do not like spending the night, is that his guest room has no access to HVAC… When our brother got his HVAC equipment, he went with a ductless option. The ductless mini split came with multiple indoor air handlers and temperature controls. The additional room did not end up setting one, then so anytime I spend the night, I have to deal with dire heat or cold. In the summertime, our brother gets myself and others a box fan if he thinks of it. This is not adequate cooling at all. I usually sweat to death the whole night. In the Winter season, our brother has a section gas furnace and electric heated blanket in the family room. This works somewhat for heating, however it is not great. You also can’t legitimately adjust the temperature control in the room. I have a guest room with access to our heating and cooling system. It makes sense to typically go to our place, and however, our brother somehow ends up getting myself and others to his section more though. It must be because he is the older sibling and can bully myself and others into it.
