Have you ever stopped to believe where both of us would be without heating, ventilation, & A/C? Don’t ask myself and others why I am thinking about this, but it just truly is on my mind.
What did the people do in the caveman afternoons for heating in & air conditioning? That truly gets myself and others thinking. I think for heating they had fire, and similar to fireplaces; However, what about air conditioning? Maybe that is why their lifespan was not too long back then, however because of the lack of air conditioning! I can tell you that without heating, ventilation, & A/C I personally would not be able to function… Floor fans & all other kinds of fans do no great if the indoor air conditions is terrible & the temperatures outside are over a single hundred & twenty degrees! That is how it is where I live in the south. Without air conditioning both of us would all die! How did people survive this section of the country before air conditioning I wonder? I can never find any information on this no matter how hard I decide to search on the internet, no matter how many clickable live links I click, there is just not enough information on air conditioning in prehistoric times, but there is not any information on heating & cooling from the start of proper human history, then all you may find is when certain devices were created! Like I can tell you that the first genre of gas furnace was a steam boiler according to a single website I read. So the question stands, where would both of us all be without heating, ventilation, & A/C? Probably dead.
