Snyder General Electric Furnace

Serial number HDM04666

Model number not visible

I believe that with that four letter start, the second two letters as a combination gives you the month and year, so I’m getting February 1977. However, I don’t have a lot of Snyder General serial numbers to make a determination that would be 100% accurate.

Does it look February 1977, and would that be consistent with the age of the house and other components?

40…The hill is in site…:shock:
