Being as outdated as I am I have seen things come and go, and I have seen things change in technology.
Especially when it comes to heating and air conditioner technology.
I have seen the dawn of central heating and air conditioner systems being put into residential homes and I even remember when gas gas furnaces were the common way people heated their homes long before central heating was available for residential towns. It used to be where central heating and air conditioner was only found in commercial buildings in the form of what they call commercial heat and air conditioner system units. But I seen all that transfer forward and by the early to mid 1990’s, most people who had an average income was able to afford to have central heating and air conditioner in their home. This was a genuinely different to see it all happen this way when I had been used to gas gas furnaces and window air conditioner systems all of my life up until that point. I have seen it all! When I was a kid window air conditioner systems were not even that common in homes. Most people had to use fans and suffer when it got real warm out because even window air conditioner units were pretty costly. That should tell you how outdated I am right there! But today’s heating and air conditioner technology I can and will divulge is much better than how it was when I was growing up, that is the real truth in my opinion!
