Came out to call for a system leaking water in the utility closet. Customer thought that the hot water tank was possibly the culprit, but the water would only happen when the AC was running. I checked system over and found a minor clog in the drain p trap, and the float switch failing to shut the system off. Discussed with customer about repair needed and also adding a pan treatment to help keep drain cleaner. Customer approved what we discussed. I was as able to clear drain with a shop vac. I replaced the float switch and added a pan treatment into the coil. Cycled system on and made sure water was draining properly. System no longer has a condensation issue.
