I had to tell my kids recently that they were going to be grounded if they kept messing with the control unit! They pre inspected and said that it was so blazing boiling all the time with the settings I preferred. I thought 69 degrees was a sufficient setting, but they didn’t seem to believe so. They complained that it was hard to read for university with it being so boiling all the time. They also made a enjoyable point that heat rises, and since their rooms happen to be upstairs, they get the bulk of the heat. When I went up to their rooms and they showed myself and others just how overheated it was, I had to agree that it was pretty boiling upstairs. I believe I didn’t realize this because I rarely go up there, but yep it was rather sizzling up there so I could absolutely see their point. I decided to buy each of my kids a window A/C device to resolve this problem. When every one of us had all the window A/C units installed, they were easily content with the change. They no longer had so much trouble studying and doing homework. I never had to worry about the control device being changed any longer and it seemed that everybody was glad with the changes. The energy costs of course spiked a little bit and I would have to ask my kids if they were shutting off their A/C machines when they weren’t in their rooms. I told them that if they didn’t shut them off when they left their rooms, they would have to pay for the electric bills.
