A through-the-wall air conditioner is a permanently installed, self-contained cooling unit that slides into a wall sleeve and vents outdoors through the wall—freeing up your window and delivering a tighter, quieter, more secure seal than many window units. Wall air conditioner models come in common sleeve sizes and capacities from 8,000 to 24,000 BTU, with select units offering electric heat or heat-pump functionality.

Match cooling capacity to room size. Adjust by ~10% for very sunny rooms or kitchens; reduce ~10% for shaded rooms. High ceilings or high occupancy may require stepping up one size.
