Through-the-wall air conditioners offer a permanent cooling solution for areas of your home that might not be connected to your central cooling system. There are a variety of units to choose from, depending on your needs. Select a wall air conditioner with a remote for unbeatable convenience or opt for a heater air conditioner combo wall unit for comfort all year long.
Wall Air Conditioner Considerations
Wall AC units involve installation. In-wall air conditioners must be vented through an exterior wall, so make sure the inside of your wall is clear of any plumbing pipes or electrical wiring. Air conditioner wall units also need to be installed with a wall sleeve – either a through-the-wall sleeve or a slide-out chassis – because an exterior wall cannot support the weight of a unit by itself.
Finding the appropriate BTU (British thermal unit) rating for your room size is an important factor to consider. The BTU rating indicates how quickly and efficiently a wall AC unit can cool down an area. This quiet through-the-wall air conditioner offers 8,000 BTUs for cooling smaller rooms, while an 18,000 BTU wall air conditioner is perfect for larger areas. Find additional information on cooling capacities and energy efficiencies.
You may also want to consider purchasing an Energy Star wall air conditioner, which consumes about 10 percent less energy compared to other wall air conditioners.
If you do not want to install a through-the-wall unit, choose a wall-mounted ductless air conditioner. These wall air conditioners are ideal when it comes to cooling, energy efficiency and quiet operation but require professional installation.
