TC, If both a/c units are running I wouldn't think it is a power problem. Generally both running on 30 amp service could cause you to pop the main or pedestal breaker. Shut the front unit off and see if the main a/c produces cold air. I'm betting it won't. I'm not an a/c guy but make sure the cooling coils, and filter are clean, and that the fan is running freely. Somebody reported mud dubbers realy like to target the fan blades. We have a couple of experts on these units a hopefully they will be along shortly to help you out. Based on you MOC # I'm thinking you have a pretty new unit. If still under warrenty and time permits I'd get it back to the dealer before your trip. If you are going to a cooler climate that 13.5 with a fan to blow the chilled air out of the bedroom might make it bearable. Good luck, Jim

My mistake, I guess I didn't read his original post correctly. I do see the statement he is only running one at a time. Jim
