I was called to a home to repair a broken air conditioner. Upon arrival, I found that the unit was completely frozen over. I called the technician who installed the system and found out that this has been an ongoing issue for the client. The technician informed me that the unit's control board, transformer, and blower motor had all been fried due to the coil freezing over. After discussing the repair options with the client, they decided not to move forward with either option.
