      Tips3
      • About 12,000 BTU covers 450-550 sq ft, 14,000 BTU 550-700 sq ft and 18,000 BTU 700-1,000 sq ft.
      • A window unit cools best the room it sits in. For several connected rooms, a ductless mini-split usually spreads the air better.
      • In the ENERGY STAR list, every unit above 15,000 BTU uses a 230 V plug; up to 15,000 BTU most run on a standard outlet.
