AC Service Complaint unit not keeping up Found unit low on r22 adds 1.5 lbs. customer would like to see if it gets them through the summer. Cooling at this time. Cannot guarantee refrigerant. Let customer know options on leak search and ball park estimate for new coil or new unit. Without conducting leak search there’s no guarantee where it is, but generally indoor coils leak so I wanted to give them an idea of cost if we took the next step.
