In my case I have the opposite problem. Our small (200 ft^2) computer room has sufficient cooling capacity and good insulation, so the summer months are usually not a problem. However on the coldest winter nights (when the temperature drops below about 1 degree F) the air conditioners often stop working. These are consumer-grade 'split' systems with outdoor condensers and indoor air handlers - they just weren't designed to be used when it's cold outside. It's not unusual for my pager to go off at 2AM on a January night (yes we have a monitoring system!) telling me the computer room is overheating. Someday perhaps we will get a 'real' CRAC system. But on those cold nights (when I'm opening doors to let the heat out) I often wonder if there is a way to cool the space using some sort of air-to-air heat exchanger. Is anybody doing anything like that? Seems like it could save a bundle on energy costs in a cool climate like this.
