I was continuously trying to fan myself with the script I was holding, it was not working, when I noticed that everyone present was doing the same, I knew I had to do something, then it was our ninth last rehearsal, and we needed to concentrate with no distractions, however adjusting the control unit settings had also not helped, so I figured that the multi-split air conditioning component must be the problem.
Later on, I went to the supervisor, he said he had noticed the heat and the change in air quality and talked to the people in charge of the hall.
They were yet to do anything about it. They should have hired a repairman who either once worked in the cooling industry or knew more about air conditioning than the one who was there who knew close to nothing. I later learned that he was filling in for someone out on sick leave. The supervisor told me to call the supervisor, who gave me the responsibility to contact the air conditioning business. Since I had no idea what the problem was other than the quality air conditioner was not working, I told the cooling system serviceman I talked to that the site needed air conditioning repair and heating and air conditioning repair. I was afraid that the indoor comfort company would schedule the repair the same day as our last rehearsal, luckily it was a day before, which was perfect. I was there at the specified time, nobody from the air conditioning provider was present. To their credit, the air conditioning company showed up numerous hours later, he tested the heating and air conditioning installation with such efficiency that I was impressed.
