Renter-Friendly Window Air Conditioners

A window unit air conditioner pulls in air from outside to provide fresh, cool air inside your home. When the weather gets hot, powerful window air conditioners can make life much more comfortable indoors. You can install and uninstall these renter-friendly devices as needed. That means you often can take them with you when you move.



Find The Right Sized Window Air Conditioner

At Lowe’s, we offer options with a wide range of practical features like window venting and convenience features like remote controls. With a remote, you can control your unit’s temperature settings from your couch or bed. Most models have multiple power settings and allow you to run just the fan on days with moderate temperatures.



A small window air conditioner is perfect for tight spaces and can circulate cool air throughout an area. Most of our AC units for small windows come with remotes and are Wi-Fi enabled. For larger areas of 350 to 500 square feet, opt for a large window air conditioner. Some models even include a heater, so you can use the same machine all year for comfortable indoor temperatures. Window air conditioners are rated by BTUs for certain room sizes. For example, a 550 square foot space would need a 12,000 BTU air conditioner. Similarly, a 150 to 350 square foot space will need 5,000 to 8,000 BTU air conditioner. A 550 to 1,050 square foot space will need 12,000 to 18,500 BTUs and a 1,050 to 1,600 square foot space will need 18,500 to 25,000 BTUs.



If you’re wondering if you can leave your window AC unit installed during winter, in most instances it can remain in place. You can insulate your unit by placing a padded cover over the interior portion of the air conditioner to keep cold drafty air from coming in. Also, you might consider a heat-control window film to insulate your windows. Remove the air conditioner window unit only if the window lets cold air in or you need the daylight from the window.



Easy Installation

Most small AC units can easily be installed in a double-hung window and usually include an installation kit. Tools typically required for a window air conditioner installation are a drill, screwdrivers, a level and tape measure.
