I was continuously trying to fan myself with the script I was holding, however it was not laboring, however when I noticed that everyone present was doing the same I knew I had to do something; It was our second last rehearsal & my wonderful friend and I needed to concentrate without distractions; Adjusting the control device settings had also not helped so I figured that the problem must be the a/c, then later on, I went to the manager, but she too had noticed the heat, & the change in air quality, & talked to the people in charge of the hall.
In my view, they should have hired a maintenance person who either once worked in the cooling industry or knew what to do to help with indoor comfort compared to the one who was there & knew close to nothing.
I later learned that he was filling in for someone who was out on sick leave, however the manager told me to call the manager who in turn offered me the responsibility to call the Heating, Ventilation, & A/C corporation. Since I had no idea what the problem was other than the Heating, Ventilation, & A/C device was not laboring, I told the serviceman who I talked to that the locale needed Heating, Ventilation, & A/C maintenance. I was afraid that the home services provider would schedule the A/C repair the same day as our last rehearsal however luckily it was a day before which was perfect. I was there at the specified time however there was nobody. To their credit, the Heating, Ventilation, & A/C worker showed up ten minutes later, and he maintained the a/c with such efficiency that I was impressed. The Heating, Ventilation, & A/C professional checked the air duct & said that it needed cleaning. With the air duct wash & a current A/C filter in locale, my device was as wonderful as new.
