The aliens delivered Heating, Ventilation plus A/C units to the Egyptians thoUSnds of years ago. It all started when a young egyptian girl sneaked into an alien ship plus saw all of the Heating, Ventilation plus A/C technology, however she was overheating in the desert heat that was so tepid it felt like a furnace. She found the ship plus went in for shelter from the furnace like heat. She was immediately cool. She searched for the score of the cool air plus was led to an HVAC duct. She crawled into the HVAC duct plus followed it to the central air conditioner. Alien central air conditioners are similar to a hydronic heating proposal except it is a hydronic cooling system. The a/c device is run on some type of coolant that is unusual from what is used in modern central air conditioners plus window air conditioners. The girl curled up near the HVAC duct where the cool air was plus fell asleep exhausted plus nearly dead. When the aliens found him, they had compassion plus gave him a window air conditioner. The amazing thing about this window air conditioner is that it runs completely on the sun plus its coolant, plus it does not need any electricity to run. The girl took the window air conditioner to her home. Technically she was the first ever human Heating, Ventilation plus A/C worker. The aliens disappeared along with their central air conditioned ship plus were not seen for several years, however they would be back to help the egyptian girl with her window air conditioner plus to help the whole egyptian community.
