System is completely empty on refrigerant R22. Saw clear indication of leak inside condenser unit. Did not perform leak check at time of visit so could not pinpoint leak. Informed homeowner of leak showed her inside of condenser where refrigerant leaked out. Advised homeowner that best solution at the moment will be to replace unit due to age and condition. Informed homeowners that repairs will be costly and also possible that parts won’t be available. Homeowner will wait for husband to get home from work so they can decide on what they will like to do moving forward.
