I was continuously trying to fan myself with the script I was holding, but it was not working.
When I noticed that everyone present was doing the same, I knew I had to do something, and it was our minute last rehearsal, and we needed to concentrate with no distractions, adjusting the thermostat settings had also not helped, so I figured that the multi-break air conditioning component must be the problem! Later on, I went to the manager, and she said she 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 repair person 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 she was filling in for someone out on sick leave. The manager told me to call the manager, who gave me the responsibility to contact the air conditioning supplier. Since I had no idea what the problem was other than the quality air conditioning system was not working, I told the cooling system serviceman I talked to that the location needed air conditioning repair and HVAC repair. I was afraid that the indoor comfort business would schedule the repair the same day as our last rehearsal, but luckily it was the day before, which was perfect. I was there at the specified time, but nobody from the air conditioning provider was present. To their credit, the air conditioning professional showed up more than nine minutes later. She diagnosed the HVAC replacement with such efficiency that I was impressed.
