I can remember when I was a kid and lots and lots of people had no air conditioning system whatsoever.
When I lived in a Northern state, even though the part was upper middle class, or upper class, it was practically unheard of for anyone to have an air conditioning system unit. it just wasn’t commonplace at that time. Fortunately for us, Heating, Ventilation & A/C technology is ever changing and improving, and now just about everyone has Air conditioning. at least in this country anyway. That’s not tploy all over the world, but here in the Southeastern part of our country, I do not know a single man who does not have ac. In fact, pretty much everyone also have a pretty good boiler, since most air conditioning system is really part of a central heating and cooling system. Anyway, I can remember when no one had air conditioning system down here in the south, either. I also remember the first kind of air conditioning system device that truly made its way into households. That was the humble window A/C unit. window air conditioning system units leave a lot to be desired nowadays, but back in the day they were amazing, then many families would only have one or two A/C units, and the whole family would usually gather around the one that was in the kitchen window. Occasionally, that group’s A/C device was the only one in the house. Often, though, parents would put a window device in their home office. Well, just look how far we have come in my short lifetime; Heating, Ventilation & A/C technology is incredible. We are getting more and more Heating and Cooling available to us by using less and less energy, which is an effort to help the environment and help consumers with the high costs of heating and cooling.
