But there are only 2 of you while there are 4 of us. We are indoors 24/7 these days due to Covid-19. Furthermore, how much time do you spend in air-conditioned environments when you are eating out? Perhaps the cost of your fine dinning added to you electric bill would alter the balance somewhat. No, I am not getting at you, far from it, all I am saying is different lifestyles, different factors at play. Finally, if it was left to me, I would have the 9,000 BTU air conditioner in the mancave running 24/7, and the three girls could do without! However, I think I would live to regret that, if I lived long enough.
