Do you keep your server(s) in a small room or closet at your office? I bet that server room gets pretty hot during the weekends when central air is unavailable. Did you know that heat is a leading cause for computer hardware malfunctions? What can you do? One approach is to buy a portable air conditioner. Not the kind you put in your window in your home. One on wheels that is made for just this type of use. There are two issues to consider. First issue is: where will the hot exhaust air go. Some brands (like APC - www.apc.com) come with an exhaust duct made for venting up through your t-bar ceiling. Other brands assume you will expel the hot air out a window. The other consideration is condensation. Some units (like APC) assume you will be able to have a drainage area that their little tube can go. Other brands, like the Fujitronic (www.fujitronic.com) are condensation-less. The Fujitronic units start at about $400. We use the condensation-less Fujitronic FA-1300 unit in our office.
