The invention of the portable a/c is honestly interesting.
I know all about it because my great Grandfather is the one who built the first prototype.
My Grandfather was one of the few Heating, Ventilation plus A/C servicemans of his time. In those afternoons, only the wealthy had an a/c, plus most homes were either heated by a fireplace or a wood stove heater. My great Grandfather was a great friend of the Heating, Ventilation plus A/C serviceman who built the first window a/c plus he wanted to contribute to the Heating, Ventilation plus A/C industry in some way. He built the first portable a/c prototype, plus it was liked by Heating, Ventilation plus A/C designers. His portable a/c design began being built, plus sold in markets around the world. My great Grandfather also built plus contributed to numerous other Heating, Ventilation plus A/C units like the portable space heater, the hydronic heating system plus later in his life, the first smart thermostat. My Grandfather saw the rise in the Heating, Ventilation plus A/C industry, plus knew there would soon need to be a special business dedicated to the sale of Heating, Ventilation plus A/C units, so he started the first cooling plus heating business where he sold portable space heaters, a/cs, parts for wood heaters, plus even air filters. His cooling plus heating business became the model for all cooling plus heating companies that started after. By the end of my great Grandfather’s life. He had started six heating plus cooling businesses, plus invented a portable a/c, current central a/c, plus the first simple smart thermostat. There is an Heating, Ventilation plus A/C museum with an entire part dedicated to my great Grandfather.
