How can I tell the age of a Carrier heat pump or air conditioner from the serial number?
Saturday, July 21, 2018
The second two digits of the serial number are the year of manufacture of a Carrier heat pump or air conditioner. This unit was manufactured in 2002.
For units from the late 1960s thru the late 1980s, there is a different serial number code, with the single number after an initial letter being the year of manufacture. So the serial number of the unit below indicates it was manufactured in 1978. Because the “8” may be for 1968,1978, or 1988, you want to look at the ANSI certification year, or year of construction of the home, for guidance. This home was built in 1979, so we determined it that way. Whatever year your figure out, it’s a really old system.
