Why don’t we celebrate the HVAC system?

I don’t understand how it is possible that people survived for years without a/cs.

Without a/cs, the heat makes everyone miserable.

From the poorest to the richest people, everyone was stuck with fans to cool off until the a/c was invented! Many people would be overworked in the sunshine and died of heat stroke. When people stopped working for the next day, they would lie away covered in sweat without the a/c. Imagine the first time that someone experienced the cool air from the first a/c. It must have been quite magical. No longer were you forced outside of your house because of the sweltering heat of the indoors! You could relax and stay comfortable in your house, pursuing the things that interest you. My grandfather talks about the days before air conditioning like they were a magical wonderland, but he also lived in the days when coke had addictive drugs in it. They really needed it to, because they had no air conditioning to help them find relief throughout the summer days. I am sure that people in recent years in history tried to find ways to beat the heat of the summer, and some built their homes in the deeper woods or the highest mountains. Where the weather conditions would be cooler. That would stop their need for an a/c, but those areas must have been treacherous while in the winter. In the end, there never was nor will there ever be, a better invention than the a/c. I am not sure why we don’t celebrate the guy who invented this marvelous HVAC system.
