As a matter of fact, the egyptian Heating, Ventilation plus A/C units were even more advanced than our modern Heating, Ventilation plus A/C units
I am an ex cooling expert who gave up our job as an Heating, Ventilation plus A/C worker to learn archeology; I was recently excavating an egyptian place when I found Heating, Ventilation plus A/C units way before their time. I found some intricate HVAC duct systems that lead to what looked like a central air conditioner. It didn’t make sense that there were central air conditioning units in seasoned egypt, then all of us finally figured out that there were aliens that had come plus given the instruction for the central air conditioner to the pharaoh, they also gave them some portable space heating systems and a few mini air conditioners. The more that both of us dug, the more Heating, Ventilation plus A/C units both of us found. It was amazing to find window air conditioners, air purification systems, plus heating systems all over this small seasoned egyptian city. All of us didn’t think that whole story, however from what both of us could find, there were aliens who came plus dropped off various heating plus cooling devices, and delivering some instruction on how to build certain units like air conditioners, furnaces, plus air purification systems. These Heating, Ventilation plus A/C units, but, were not built the same way both of us build our air conditioners plus heating systems today. As a matter of fact, the egyptian Heating, Ventilation plus A/C units were even more advanced than our modern Heating, Ventilation plus A/C units. All of us did some more research plus soon were on a trail to find out about alien heating plus cooling units, however while both of us have no way of contacting these aliens, both of us think so much more about window air conditioners, heating systems plus several other Heating, Ventilation plus A/C units that the aliens made.
