My 0.02 ... I'm getting bids myself; the owners have always gone cheap and so far I have a little 'room a/c' unit that I had to rig up with my own insulated pipe to exhaust the hot air into the return air plenum (i.e. above the drop ceiling tiles).
Full rack, about 10K BTU's, 18k if you include the fridge and coffee pot. Yea, not my choice. Movincool has a unit that looks pretty easy to install, but so far all of the installers want MORE money than the unit costs to lift it up above the ceiling tiles and hookup the 2 ducts to the room. Here's the Movincool: http://www.movincool.com/portable-air-conditioner/cm25.php The price is pretty similar to the comparable Liebert (Emerson power) unit though, so we'll probably go with Liebert. Building A/C is usually just about enough (room is about 70-80 during the week), but on the weekend they shut it off. We exploded a can of soda in the room once: One can in the 6 pack spewed and knocked the 6 pack off. Not sure if it exploded on the rack or when it hit the floor. Yea, we have office supplies in there too.

Currently, I have two HVAC bids regarding the expansion of our server room. (It will seem strange to have that room below 80 degrees, and I am not kidding with that number!). We have two proposals and with two different units, both 15 tons. One is by Stulz, and one is by Liebert. Anyone care to offer their opinions/experiences/etc on the advantages one has over the other?
