no, the amount of harmful bacteria etc. is much lower in cold water, so much lower that the governing body of the water agency you get the water from deems it safe to use!. it's the vastly increased amounts of bacteria etc. in WARM water that makes it unsafe, they grow to dangerous levels in WARM water!!. have the condensate from your A.C. tested sometime!!.
