Requesting Help on ages of HVAC & HW

A Whirlpool air handler for a heat pump is mfg# 88355K69, Model # DSUU24AN, serial # 14768. Any idea on the age?

Electric hot water heater: State Select Model# ES640DORT, serial # CO6A168958, Item # 9241225005. Any idea on the age?

Anywhere I can find out information on condensing units by “Miller” Nordyne Nortel Co? The model and serial numbers are illegible.


Just a guess, but the air hanedler looks like a 1976 and the water heater a 1989.

How old was the home?

I agree, the water heater is probably 16th week of 1989.

The residence was built in 1969 so these items are definitely not the original.

Thanks for your help.
