Arrived for ac out. Upon arrival I found the wet switch was tripped. The pan was dry though, so could have been a bad switch. I replaced the switch. System started up. The filter was very dirty and I changed it. There was only a 14 degree temp split and it needs to be at 20. I went outside and check charge and it was reading low on refrigerant. The capacitor has also failed. It will need to be replaced. System is running for the night, we will be back in the morning to diagnose further.
