Service diagnostic found that the outdoor starter was stuck closed and was constantly sending voltage to the outdoor system. I spoke with the homeowner and he chose to have the contactor replaced and to sign up on our gold maintenance plan with the first visit this winter. I replaced the outdoor contactor and function checked the system. I also sealed some air straws at the furnace and secured the outdoor compressor wiring at no additional cost. No other issues were found. The system is operational at completion of service.
