The simple answer is yes. Most portable air conditioners come with a complete window vent kit. The main part of this kit sits in the window sill and should be connected to the exhaust hoses of your portable air conditioner. The window venting kit will generally git most standard windows, however, it is advisable that you measure your window to ensure the venting kit will fit. If the window vent kit that comes with the portable air conditioner you want to buy is not the right size for your window, you may be able to order one or have one custom made for your particular window size.\r
