Guestroom has no HVAC

I don’t care for when I get stuck spending the night at my siblings, and about once every more than one weeks my sibling and I go out to the bars… The people I was with and I don’t celebration too much, so we spend the night after a bar day… If we do the bars near my locale, my sibling crashes with me, most of the time though, we go to her area and I end up in her guest room. My sibling has an amazing house, sizable backyard and a pool. The reason I don’t care for spending the night, is that her guest room has no access to Heating as well as Air Conditioning, and when my sibling got her Heating as well as Air Conditioning equipment, she went with a ductless option. The ductless mini split came with several indoor air handlers and thermostats. The guest room did not end up setting one, but so anytime I spend the night, I have to deal with drastic heat or cold. In the summer, my sibling gets me a box fan if she thinks of it. This is not satisfactory cooling at all. I usually sweat to death the whole night. In the winter, my sibling has a space gas furnace and electric heated blanket in the kitchen. This works somewhat for heating, however it is not great, but you also can’t genuinely adjust the temperature control in the room. I have a guest room with access to my heating and cooling system. It makes sense to always go to my locale, however, my sibling somehow ends up getting me to her area more though. It must be because she is the older sibling and can bully me into it.
