Goodman Furnace: Reading the furnace model number
Reading the furnace model number on a Goodman furnace: The 14-character model number identifies the brand (A = Amana, G = Goodman), configuration (M = upflow/horizontal, C = downflow/horizontal, K = dedicated upflow, D = dedicated downflow), gas valve type (M = modulating, C = 2 stage, H = convertible 2 stage, S = single stage), AFUE rating (80, 92, 96 or 97), input capacity in MBtu/h (030 to 120), and maximum CFM (3 = 1200, 4 = 1600, 5 = 2000). Cabinet width is coded A = 14 in, B = 17.5 in, C = 21 in, D = 24.5 in. The nomenclature layout on the page is jumbled, so confirm any position not listed here against the rating plate.
Applies to: ACVC96, AMVC96, GCVC96, GMVC96 furnaces
