Determining the age of HVAC systems and water heaters can be more intricate than simply checking the equipment's data plate for a manufacturing date. Most manufacturers encode the date within the serial number, using a specific date code system unique to each. To accurately decode this information, you can refer to the Building Intelligence Center HVAC and Water Heater Index. This resource is invaluable and worth bookmarking for quick access whenever needed. For your convenience, we've included a link below.
