I'm not sure Central Air would solve my problem.  The ambient air temp in the basement never climbs over 20c.  Adding central air would help with any humidity issues I might have but I don't believe it would do much in the way of cooling the tank unless I dropped the temp in the basement a significant level, which would make it uncomfortable for me to be in the basement.  Hard to work on the tank in my parka! *laugh* 
 
I think I read somewhere that it takes four times more air to equal the cooling capacity of water.  I think I might be stuck with the chiller.  I have being eying up the Pacific Coast Imports 1/2HP.  People seem to have good things to say about it.
