How to Read Carrier Serial Numbers
Carrier serial lookups start with the exact label text, so copy the full serial number without guessing or trimming characters.
Many Carrier-family systems encode production timing in a short character sequence that can be decoded once the format is identified.
Where to Find the Serial Number
Outdoor condensers and heat pumps usually place the serial label on the cabinet exterior near the service side.
Furnaces and air handlers commonly place the plate inside the burner compartment, blower area, or cabinet face.
