How do I determine the age of a DiamondAir heat pump or air conditioner?
Tuesday, June 29, 2021
The first two numbers in the serial number are the month, and the third and fourth numbers are the year of manufacture for a DiamondAir system. If the serial number is missing from the data plate, or worn away, you can call DiamondAir tech support at (813) 885-7999 with the name or address of the original owner, and they can look up the date of manufacture for you.
For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner? And to figure out what all the other numbers listed on the condenser data plate mean, go to our blog post How do I understand the air conditioner or heat pump condenser label (data plate)?
