When I was in college I had to study for my final exam.
And what I found was that having good air conditioning was the key! When I had some very light but good air conditioning running I was at all my best.
It was a good thing that the house that I was renting and sharing with a roommate was very well equipped with the very best in central heating and air conditioning at that time. My roommate was more or less the same as I was with needing quality air conditioning to be able to study real well. It was something that we both agreed on. So it was always a thing that the central heating and air conditioning system’s cooling was always working top notch. To ensure this we always called the local heating and air conditioning company every few months to come out and do a heat and a/c tune up and check up on the central heating and air conditioning system unit. We would split the cost of the heating and air conditioning home services bill because it was something that we both believed in and needed just as much. We wanted to have top quality air conditioning in the house so that we both could study for the exams with had. Especially that final exam which was the most important because it made the difference on if we passed the college we worked so hard for and paid a lot for or not! Needless to say thanks to the quality air conditioning we both passed with honors and went on to have great careers in life.
