Central air is an excellent way to cool your home, but a window air conditioner is your second-best option if that is not an option. Window ACs can cool any room with a single- or double-hung window. You can keep costs low when you choose an Energy Star *-certified unit. All of our window picks are certified.
Window air conditioners are safe and easy to install if you follow the manufacturer’s instructions. Most models feature security brackets to keep burglars out and your AC in place.
If your window is not suitable for a window unit, consider a portable air conditioner. We’ve listed our best portable air conditioner pick in this guide, but you can also check out our portable AC guide.
For this guide, we tested 13 window air conditioners and consulted with Enesta Jones, a spokesperson for the US Environmental Protection Agency (EPA). We put each unit through a series of objective tests. Additionally, we answer your air conditioner FAQs and define some common terms.
