How to Choose a Portable AC (BTU Sizing)
Size by room, not by price. ~20 BTU per sq ft.
Small rooms
~350–400 sq ft — bedrooms, offices. See 8K models.
Medium rooms
~500–550 sq ft — living rooms. See 12K models.
Large rooms
700+ sq ft — open plans. Prefer dual-hose.
Deduct ~10% capacity for very sunny rooms or ceilings above 8 ft. An oversized unit short-cycles and feels clammy — match BTU to room.
