When I went to university, I don’t remember there ever be any cooling system in the classrooms. I remember resting in the classroom and having it so hot that the sweat would be rolling down your back. Everyone had the sweat stains and no 1 thought anything about it. The only 1s who squirmed were the ladies, if you tried to deliver them a hug around their neck when you were dripping. It would have been nice to have cooling system, but the people I was with and I were a small university district. Our university was old, and no 1 offered it a hour thought. The people I was with and I would go lake house to our homes that didn’t have cooling system. There would be fans running to help cool it off. The shades would be pulled to help keep the sunlight out of the house. That way it would be cool since there was no solar heating. Now, people want their shades pulled at night, and the sunlight coming in during the day. That is a nice concept, but it does not keep out the solar heat. Instead it is easier to rely on the cooling system. Air conditioning is in nearly every home. That is why I decided to go to university for heating, ventilation, and cooling system when I graduated from high university. It took myself and others nearly more than one years to get my certification and I have undoubtedly been enjoying now working for the local Heating and AC business. In a couple of years, I am hoping to be able to start a heating and cooling system company of my own.
