Dual Zone Control for Whole House A/C

I have a 5 TON Unit (Carrier) and a WHITE RODGERS 1F90-371 Programmable Thermostat in a 5/4 Private Dwelling. I've started using a closet for all my I.T. Gear, Servers, Raids, WiFi Routers etc... as you might guess; the I.T. Closet's become a hot-box. I'm not happy with the idea of keeping it open all the time since quite a bit of noise is generated from it. I'm tinkering with the idea of having my A/C come to the rescue! Is it possible to keep the closet cool 24/7 without making the rest of the family members feel like they're in alaska?

Will it require extensive work, dampers, Dual zone control thermosat's, dedicated thermostats, I'm quite the handy man -- can I do it?

Please help! :o)

To zone just that one room it will not work. A 5 ton unit needs to move around 2000cfm to keep from freezing up. (that would be 10 8 inch ducts) I would look at using a high cfm bathroom exhaust fan to take the heat out and maybe cut the bottom part of the door off a extra half inch to let fresh air in.

You make mucho sense! What size (CFM) bathroom exhaust fan do you recommend? The closet is about 6' x 3' and the bottom of both doors that open into the closet have a 2" gap at the bottom. The room reaches 90 degrees Fahrenheit... Do you suppose a thermostat can be placed to control when the bathroom exhaust fan kicks in, or just let it run continously? I'm also concrened with the noise this fan would generate.

Thanks!

The under cut on the door will be fine. the exhaust fans the have now you wont even know its running. the fans pull very little amp and are made to run all the time if you want. I would instal it to turn off and on with a light switch and let it go.
