How do I determine the age of my heat pump?

Friday, December 13, 2019

The date of manufacture is encoded in serial number on the data plate of almost all heat pumps. Go to the outside unit (condenser) and look for the metal plate or sticker on the side with the manufacturer’s data. Each manufacturer has their own system. Sometimes it’s the first two numbers, or second two numbers, or second and fourth, or even a letter code. Find your brand in the list below and click on it to go to the page with specific instructions for determining when your unit was produced, with actual data plate examples.
