You have to support a standard window air conditioner either from the bottom with a bracket or the sides with a window kit. When using a window kit, you must account for at least an extra three to four inches for the accordions to fit.
Slider window air conditioners also come with a window kit, but if you have a particularly tall window you may need to purchase additional plexiglass, wood or another filler to seal the space above the air conditioner.
Casement window air conditioners also come with a window kit, but if you have a particularly tall window you may need to purchase additional plexiglass, wood or another filler to seal the space above the air conditioner.

BTUs are units of power - the larger the area you need to cool, the more BTUs you need. To calculate how many you need, use our BTU calculator.
These air conditioners vent on the sides and the back and are designed for thinner walls. The chassis slides away from the back of the unit, called a sleeve. You remove the chassis and install the sleeve into the window or wall. After the back of the unit is secure, you slide the chassis back into the sleeve.
Through-the-wall air conditioners vent only through the back of the unit and are ideal for thicker walls. A sleeve is required for installation, which must be purchased separately. If you are replacing your current wall air conditioner, you can use the existing sleeve. Here are the standard sleeve sizes from different manufacturers.
Packaged terminal air conditioners are commonly used in the hospitality industry. They are 42" wide and installed through an exterior wall. PTAC units require a wall sleeve and exterior grille which are both sold separately. Wall thermostats and remote controls are available for most models and are also sold separately.

Voltages vary based on the type and size of the air conditioning unit. Different voltages require unique plug types to accommodate the necessary voltage. If you have a specific voltage at your installation location, you should narrow your search to units that will fit your needs. When unsure you can check the plug type as a quick reference of voltage.
