Translation: Hire a f***ing professional. And that's exactly what you need to do. Qualified HVAC installers (with specific data center experience) will know far more than us "network types" will ever want to know about cooling. They do this for a living, and thus, know all the tiny details and odd edge cases to look for. (like looking above the drop ceiling -- that's what it's called, btw -- and seeing what's up there long before pencil meets paper (not that anyone uses paper anymore.))
Ricky, You shouldn't even *have* a drop ceiling in a modern computer room. You want the room to be as tall as practical so that the air from the hot aisles has somewhere to go on its way back to the HVAC, other than back through and around the cabinets. Personally, I've found that there's a pretty wide disparity between HVAC professionals that are capable of hooking up a CRAC and turning it on versus HVAC professionals that understand the holistic picture including hot aisles, cold aisles, humidity control and flow. I wouldn't want to call in a professional without first understanding the problem well enough to assess whether I was getting a competent answer. Regards, Bill Herrin -- William D.
