When we moved to a house in 2018, it already has an AC unit installed. We turned it on once to test if it was functioning when we first moved in but we haven't use it at all in 2018 or 2019. It was only this past Monday that we turned the AC on for the first time. I supposed it is a combination of hot weather and working from home.
By the way, what kind of energy costs are we talking about with turning on the AC at home?
