Let’s switch which air filter we use

My roommate Cara leaves in one month plus I could not be more excited. I have gotten to where I dislike having a roommate. It is not that Cara is so bad, I just want to live by myself. I want to decide what I eat at night with no input. I want to clean or not clean if the mood strikes. I also want sole control over the heating and cooling! With Cara, I have to make sure the temperature suits her needs too. In the Winter, Cara absolutely wants more heating than me. I would rarely run the oil furnace to save a little money in the Winter! Cara wants it to be around 78. So the two of us compromised, which means neither of us were ecstatic. In the Summer, I feel having more air conditioner plus paying more is worth it. Cara has this odd thing were no air can hit her. She won’t sit near the HVAC ducts plus will turn off the AC when I am not home. I then come back to the beach house from my job to a stifling house. I can’t wait for her to leave so I can change that. What I really will do is get rid of our furnace entirely. I will just get a small electric furnace to use on those actually freezing days. In the Summer, I will run our air conditioner idea at all times. I will make sure I get AC when I return from work. I guess heating and AC control is actually the one thing I am looking forward to most. I guess I could handle cooking plus cleaning as a team effort.
