Upon my arrival in Paige I did Air Conditioning. spoke with the customer about their concerns with the system displaying a communication error to the outdoor unit. Performing my diagnostics I verified high voltage at the outdoor system and verified it was getting DC voltage. I found the unit was not getting 24v supplied from the indoor to the outdoor. I then checked the indoor system finding that the water removal system was backed up causing the float switch to trip. Spoke with the customer about their repair options and went over maintenance. Customer approved to move forward with both today. I cleared the water removal system then stress tested it with a gallon of hot water and drain pan solution. System is now operating to manufacture specifications at this time.
