Thread: Age of Lennox Heat pumps

I'm trying to figure out the age of these heat pumps
The realtor said they are new, they sure don't look like new units.
The serial #s are 5605H07263 - 5605E 01858

Thanks

For Lennox products: 1st & 2nd Digits = Factory, 3rd & 4th Digits = Year, 5th Letter = Month (from A to M, A=Jan, I is not in use, M=Dec)

These heat pumps are 2005 August & May.
