I was continuously trying to fan myself with the script I was holding, however it was not working, and when I observed that everyone present was doing the same I knew I had to do something, then it was our second last rehearsal & my friend and I needed to concentrate without distractions.
Adjusting the control unit settings had also not helped so I figured that the problem must be the a/c unit, later on, I went to the manager, and he too had observed 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 guy 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. The manager told me to call the manager who in turn gave me the responsibility to call the Heating, Ventilation plus A/C dealer. Since I had no idea what the problem was other than the Heating, Ventilation plus A/C unit was not working, I told the serviceman who I talked to that the place needed Heating, Ventilation plus A/C maintenance. I was afraid that the house services provider would schedule the air conditioner maintenance the same afternoon as our last rehearsal however luckily it was a afternoon before which was perfect. I was there at the specified time however there was nobody. To their credit, the Heating, Ventilation plus A/C serviceman showed up ten minutes later, and he tested the a/c with such efficiency that I was impressed. The Heating, Ventilation plus A/C professional tested the air duct & said that it needed cleaning. With the air duct disinfect & a new air conditioner filter in place, my unit was as fantastic as new.
