The spot coolers provided Climage Control Solutions saved the day at my office when our central ac went out in the entire building. The portable ac units kept us all very comfortable for several weeks while we waited for ours to be repaired. It only took 2 units to cool quite a large space. Thanks you CCS!!! We appreciate you!

The MOB-250's provided by Climate Control Solutions saved the day when our central a/c units went out at our corporate office.
