We arrived to clients home for evaporator change out. Once we hooked up our gauges, we realized there was zero refrigerant in the system. We proceeded to take out the old evaporator and place the new one in. We finished brazing the lines and put the system in vacuum. After reaching its required vacuum level, we charged the system with 7lbs if r410a. We let the system cycle for 20 min so we could get an accurate reading. We checked out supply and return temperatures and we were satisfied with the cooling. We wrapped up the job and thanked customer for their business.
