Customer needed system to be recharged as he had another contractor doing some work and the contractor let the refrigerant out. I recharge the mini split system back up with 4 pounds of refrigerant. Additionally, he asked if I would also look at his Goodman split system in which I suggested the system also needed an additional 3 pounds of refrigerant. The customer agreed to allow me to recharge that system as well. Total charger, refrigerant for both system was 7 pounds.
