I need help determining the date of manufacture for this air handler. According to building-center.org it is 1932. I know that is not right. Thanks.
I did see the style 5 but there is only the one letter in the serial number. 1993 does make sense being the condo was built in 1994 and the unit looks original and is not in good condition so I’m only going to say “manufacture date undetermined but unit appears to be original”. Thanks for the help John.
