Product Number Breakdown

Example model numbers from the imported spec sheets, labeled by part with compact option tables like the printed model-number guides.

Common cooling capacity codes 018 = 18k BTU/h / 1.5 tons, 024 = 2 tons, 030 = 2.5 tons, 036 = 3 tons, 042 = 3.5 tons, 048 = 4 tons, 060 = 5 tons. Furnace and gas/electric heating capacity codes are BTU/h input, not tons.
