Our commercial refrigeration technicians completed approved repairs on a freezer that was suffering from air intrusion into the case. The unit had been shut off for the system to de-ice, and left off for the sealant to properly cure. Our tech returned today to complete a final inspection, recharge and reconnect the refrigerant lines. Unit is up and running per specs again. We will send a technician back per manager's request 5/31 to do a final courtesy follow-up.
