Arrived to property met with Tom who introduced us to apartment tenant and led us to outdoor unit. Showed us where the leak in the liquid line is. Removed refrigerant from lines and crimped in new fitting. Moved to indoor unit to braze and install new filter drier. Returned to outdoor unit and connected vacuum pump to system to remove atmospheric pressure before recharging system. Added 3 pounds of refrigerant to calibrate the system to factory charge. Thank you Tom and have a great day.
