Finally got the A/C running in the main workshop (2 1/2 ton Unico system through 12 air drops) and the system works great for controlling temperature. Unfortunately, humidity is the enemy to the cars and tools in our garages and with the heavy weather we've been having here in the Northeast, the A/C system will not maintain the desired humidity levels (45-55%). With a 72F setting, room humidity was 70% this morning, enough to allow mold and surface rust on bare metals to creep up in the shop.
As a stand-alone system, I installed a Therma-Stor Air Purifying Dehumidifier, mainly to bring fresh make-up air into the room, never really expecting that it would be needed to control humidity with an A/C system in place. The humidistat allows precise humidity control and in less than 10 minutes, the 70% humidity was down to 52% in a 20x32' room with 12' ceilings.
I'd highly recommend the use of a dehumidifier in a nice garage, even if its a small 30-40 pint unit available through the home centers. Air conditioning is not enough (unless you live in the Southwest with very dry conditions). See http://www.ultimategarage.com/UltGar2g.htm for some pics of the system I used.
