How do I find the age of a Haier heat pump or air conditioner from the serial number?
Monday, March 28, 2022
Many Haier units have an 8-digit serial number, with the first two digits being the year of manufacture, and 3rd and 4th digits the month. So the data plate shown above indicates the Haier room air conditioner was produced in February, 2007. Haier publishes charts for the longer serial numbers, with up to 20 digits of both numbers and letters, at https://www.haierappliances.com/support/support-content/35198, but several units we have examined have serial numbers that do not conform to their published data formats.
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)?
