Compare Classic America Mini Splits and Window ACs

Every system in the lineup with every published spec in one table. Figures come from each model's spec sheet; where a sheet does not confirm a figure we say so rather than estimate it.

The table is the spec sheets in one view. Each column is a Classic America system, and each row is a figure those sheets publish: capacity, efficiency, voltage, coverage, line set, sound, and the other rows on the page. If a sheet does not confirm a number, the cell says so instead of borrowing one from a different model. Window units and mini splits are different machines, so some rows apply to only one of them. Use the table when you are choosing between two sizes, then open the product page before you buy. Coverage on the site follows the published maximum for that model. A sunny room or a tall ceiling can still need a different size, which is what the size finder is for.

DUET SEER2, EER2 and HSPF2 are the published non-ducted ratings for the wall-mounted indoor units it ships with. Heating at 5°F is the published low-temperature capacity where the sheet gives one. Coverage follows the maximum of the matching band on the ENERGY STAR room air conditioner sizing chart (8 ft ceiling, average sun). The 12,000 BTU window unit uses the 400–450 sq ft band. DUET is two rooms, up to 400 sq ft each. Operating temperature is spelled out here for MSC-12HAC1 only.

The DUET outdoor unit alone is 103 lb. The 123 lb figure includes its two line sets and two interconnect cables.
DUET ships with 2 indoor heads in one large box, about 178 lb total.
The large shipping carton adds about 7–10 lb, and a pallet, if used, can add up to 30 lb.
