What the numbers tell you

The model number identifies your specific unit type and capacity. The serial number reveals the manufacturing date and sometimes the plant location. Many manufacturers use coded serial numbers where the first four digits represent the year and week of production. For example a serial number starting with 2415 means the unit was built in the 15th week of 2024.

Common locations by neighborhood

In older Coral Gables homes with historic architecture the data plate might be behind a removable panel. In newer Aventura condos the plate is often on the exterior wall near the ceiling. If you cannot find the plate take clear photos of all sides of your unit and contact a local HVAC technician who can help identify the information.
