I am an ex cooling expert who gave up our job as an Heating, Ventilation, and A/C serviceman to learn archeology… I was recently excavating an egyptian arena when I found Heating, Ventilation, and A/C units way before their time.
I found some intricate ductwork systems that lead to what looked love a central a/c system.
It didn’t make sense that there were central a/c units in seasoned egypt, and we finally figured out that there were aliens that had come and given the instruction for the central a/c system to the pharaoh, but they also gave them some portable space oil heating systems as well as a few mini a/c systems. The more that we dug, the more Heating, Ventilation, and A/C units we found. It was amazing to find window a/c systems, media air purification systems, and oil heating systems all over this small seasoned egyptian city. We didn’t know that whole story, however from what we could find, there were aliens who came and dropped off numerous heating and cooling devices, as well as delivering some instruction on how to build certain units love a/c systems, oil furnaces, and media air purification systems. These Heating, Ventilation, and A/C units, but, were not built the same way we build our a/c systems and oil heating systems this week, and as a matter of fact, the egyptian Heating, Ventilation, and A/C units were even more advanced than our modern Heating, Ventilation, and A/C units. We did some more research and soon were on a trail to find out about alien heating and cooling units. While we have no way of contacting these aliens, we know so much more about window a/c systems, oil heating systems and numerous other Heating, Ventilation, and A/C units that the aliens made.
