If so, this is a very common problem. If your air conditioner is leaking outside, it means, there may be nothing wrong with the installation or air conditioner itself. Due to condensation, air conditioners sometimes have to leak outside. If it's dropping water on the side walk or annoying your neighbor downstairs, then you should have a solution for this. We build customized drain pans or funnels (your choice) and attach hoses underneath the air conditioner to re-route the water. This is a very effective solution to this problem.
