My parents got separated and I got my father in the split. My dad needed a place to go and I had a spare room. I sort of see now why my mother kicked him out. My dad is a immense slob, tracks dirt, consistently wants potatoes for brunch and is weird about Heating, Ventilation, and A/C settings. My father is always messing with our home’s thermostat. Basically my dad wants the condo to be 71 degrees no matter what. In the Summer I don’t dare turn on the A/C. He just about loses it when he feels the frigid air. In the winter our furnace is going on all afternoon, everyday. My energy bills have never been so steep. My father is basically starting to mold he has been in our condo so much. I never get even one hour with typical weather conditions control. I am thinking about Heating, Ventilation, and A/C zone control. I could get a ductless mini split system and set up a device in my dad’s room. My dad could control the Heating, Ventilation, and A/C device to what he likes. Then the rest of the condo every one of us would need to said yes on a temperature. If my father dominates those areas as well though, I will at least have a family room that is the correct temperature. But, how long is my dad going to be living with me? Zone control is not exactly a cost free investment. If there is a chance of him moving out, I won’t buy it.
