Best window air conditioner for a garage

Garages gain heat through the door, the roof and uninsulated walls, so they need more capacity per square foot than a bedroom. A unit that also heats makes the space usable in winter.

Tips4

Size up one or two steps from the floor-area table: an uninsulated garage door and roof add a lot of heat.
Insulating and weather-stripping the garage door is cheaper than buying a larger unit.
Many garages have no window. A through-the-wall unit or a mini-split is the usual alternative.
Window units that heat are made for mild weather. In cold states, check the maker’s lowest outdoor temperature for heating.
