As with all serve racks, they sound like jet engines and this one was no different. I tried to soundproof the room and door, but to no avail. So, it remained a continuing issue for all the surrounding offices.
There were also the thermal and moisture issues do to an oversized split A/C system. This along with un-insulated walls, hollow core door, and A/C freezing up I had to find an alternate solution as this was never going to work long term.
