Riding the heat wave last summer, a unit in my storage room was leaking. It took City Heat and Air a day in a half to two days. The condensation drain stopped up and the guy just set it out and ran it for a little while. It worked very well. This time, the guy came to service my air conditioning before I turned it on. Once we turned it on, it started leaking. He actually right then put in a whole new pipe joint. We've been using it since and it was great that he fixed it on the spot.
