She is not happy about heating

My parents just got divorced and I recieved my father in the separation, and when they first cut I was extreme on my mother.

I thought she was throwing in the towel early.

I did not listen to the reasons why she could no longer handle my dad, however now that she is living with me full time, I get where she could wear on a person… My father is harshly demanding. She wants meat and potatoes for every lunch and can’t make it himself. She doesn’t clean up after himself, do laundry or offer to help out around the house. She also is freaky with temperature control. She consistently wants the heating method on, even in the summer. I have tried hiding my wireless thermostat remote and my dad consistently finds it. I have begged him not to turn on my furnace or to turn it off before I get home. I am consistently coming into a sweltering house. My energy bills are so high! I am now looking into adding Heating and Air Conditioning zone control to my house. If I can get her room on a separate Heating and Air Conditioning program, maybe all will be okay. My dad could have her own thermostat and have as much heating as she wants in the space. I am wondering if that will be satisfactory. Knowing my dad, the dining room, kitchen and lavatory all will be heated as well, however even splurging for many indoor air handlers and thermostats, it might still be the same problem. She is super unsatisfactory. I don’t suppose how much longer I can take him.
