How can I tell the age of an Affinity air conditioner or furnace from the serial number?
Saturday, June 23, 2018
Affinity is the high-efficiency HVAC brand of York International, a division of Johnson Controls. The second and fourth digits of the serial number, taken together, are the year of manufacture of the unit. So the serial number on the data plate of an Affinity series heat pump condenser shown below indicates it was manufactured in 2011.
Also, see our blog post How many tons is my Affinity air conditioner or heat pump? For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner?
