In the summertime, my cousin Lisa keeps the temperature in his home office as chilly as possible. I personally like to sleep in a room that is chilly so that I can cuddle up under my blanket all year long, however if a room gets too cold, it could become a bit uncomfortable. My temperature control is set to about 72 degrees at nights in the Summers and then, I use a ceiling fan for additional cooling. This is the perfect temperature for a really comfortable night of sleep. However, that is too warm for my cousin Lisa because the temperature in his home office feels more like an icebox. She keeps a few pieces of unit running at night to ensure that his home office remains at a certain temperature. Lisa sets the temperature control to his Heating, Ventilation, and A/C method at 70 degrees, then he has a digital remote controlled window air conditioning system that he keeps at 66 degrees, and finally, he turns on his ceiling fan plus his sitting fan. If he could transform his room into a freezer, I guess he would make the sacrifice and do it. Of course, his energy bill is a bit excessive as a result of the way he uses his cooling system, but he doesn’t care, he would rather spend the extra money to sleep in what he deems as a comfortable room. I guess it is a bit much, however that is my opinion. What do you think, is an Heating, Ventilation, and A/C system, a window air conditioning system, and 2 fans necessary for a comfortable night of sleep in the Summer? My cousin Lisa entirely thinks so.
