I was watching this new construction show one morning when i woke up in a hotel called Michael holigan. He was showing the best Central AC units to go with in new contruction. He said if your willing to pay some money the best one is a water cooled central AC unit. He said its more up front cost put lower operating cost. He said something like If you take a hose water down the coils on a ac unit when running it will blow colder air. This is basically the way a water cooled AC unit works. Is he rite. Is that the best unit to go with if you can afford it. Does it have a lower operating cost?
