A/C Age?

Can anyone supply a date of manufacture for the following A/C unit?

Manufacturer: CONCORDE

Model Number CCU10C30A

Serial Number: 1605D06050

The type of serial number would seem to indicate the sixteenth week of 2005.

For the most part you can guess based on those first 4 numbers.

Also see inspectpedia.com for a chart.

Same as Lennox it is a 2005

Thanks guys.
