 So, everybody needs air conditioning. It's 120 degrees out here daily to support everybody's mission. We clean the filters, the coils, inspect the fans, ensure the board's clean, and every component's looking like it's supposed to. Just doing an operational check of the unit and verifying the unit's performance. A lot of people that need air conditioning, we provide that by doing preventative maintenance on about 10,000 air conditioners, whether they be environmental control units, like what's behind me here, or split units and package units. Out here we provide support for maintaining common equipment, food and perishable items, medical equipment, and then your sleeping quarters. So, if there's a difference in air, HVAC was there. Stay cool.
