One day many years after receiving his window air conditioner, the egypitan man noticed that his window air conditioner was no longer working well. He tried to fix it, but there were no heating and cooling businesses that sold heating and cooling equipment for sale. On top of this, he had no idea how to fix a window air conditioning unit on his own. He did what he could to contact the HVAC aliens, and with time, they came. The aliens took the young man and his window air conditioner. They showed him how to take the window air conditioner apart and fix it. They also showed him how to clean air ducts. After showing and teaching him everything about cooling units, they moved on to their hydronic heating units. These hydronic furnaces are way more advanced than any hot water boiler heating system or furnace we have today. The young man learned all he could. Then the aliens came to the egyptian city and introduced the pharaoh to central air conditioning and window air conditioning. In this city, the heat is all they really were concerned about as furnaces were not really ever needed in the desert. The young man became the city’s first HVAC technician and he opened the first heating and cooling business ever. He was very busy fixing hydronic cooling systems and window air conditioners. He even started a school where he would train young men to be HVAC technicians. All of this history was discovered by an ex cooling expert who became an archeologist and an HVAC scientist.
