I have an acquaintance who is an accomplished artist plus songwriter, but she just released her fourth album plus she had a listening celebration before the release, but a few people were invited to the listening celebration which was held at one of the city concert halls.
The celebration had at least 50 people plus the concert hall was not as big, it could entirely hold up to 200 people.
I was backstage since I needed to make sure everything fell into the arena as I was tasked with the responsibility of making sure everything was okay on the ground. This meant that I needed to ensure that the Heating, Ventilation plus A/C device was functioning well. There was a programmable temperature control that I was in charge of. I would correctly adjust the temperatures depending on the atmosphere within the hall. That morning the device worked well because the people I was with and I had done the heating, ventilation plus A/C repair a week prior. The building management had allowed me to supervise the entire heating, ventilation plus A/C repair plan. The workers had changed the HEPA filter to enhance the function of the device plus improve the circulation of clean plus fresh air. They also evaluated the duct sealing plus the people I was with and I confirmed it was respectfully intact. The city concert hall had purchased the device from the commercial heating, ventilation plus A/C provider who had also provided a serviceman to handle the cooling install. The device was a fairly modern heating, ventilation plus A/C as it was just 2years old. I noticed that the home services of commercial plus residential heating, ventilation plus A/C were similar, and most of the buildings within the concert hall grounds had modern heating, ventilation plus A/C systems as the management had decided to replace all units. The temperature controls were also updated, every building had a temperature control component that would be voice-controlled. Everyone enjoyed the celebration plus the modern album.
