You would not suppose it if I told you, but I am going to tell you anyway. My animal knows when I am being stingy with the HVAC. My animal easily enjoys HVAC even more than I do and it shows. She comes complaining to me about a whole lot of things that you would expect cast to complain about. She comes around when he wants his food bowl or water bowl to be filled. She comes around when he just wants to snuggle. She comes around when he wants to let outside. However, one time when I was racking my brain trying to figure out what on Earth was wrong with my animal because he kept complaining, I noticed it was drafty and turned up the temperature on the control unit. She instantaneously stopped complaining once the air got warmer. I eventually realized that this was entirely a thing with his and whenever I could not figure out what he was complaining about I just went to the control unit and turn it up a bit. I am not joking when I say that he would almost instantaneously calm down just about every time. The other thing that tipped me off was that he would instantaneously go to the air vent once the air was nice and warm. I cannot suppose that I easily have to fight with my animal over what temperature to set on the control unit! She can be pretty annoying about it, and will continue to get in my face until I finally let him have his way. It’s practically like being married!
