How can I tell the age of a Heil air conditioner or furnace from the serial number?
Saturday, June 23, 2018
The Heil brand is produced by International Comfort Products. Units produced since the early 1990s have a serial number that is a single letter followed by a series of numbers. The first two numbers are the year of manufacture. So the serial number shown below indicates that the condenser unit was manufactured in 1991. See our blog post How many tons is my Heil heat pump or air conditioner? for the size of your Heil unit. And the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner?
