The Best Deals on Window-Mounted and Portable Air Conditioners Right Now
Find the right fit for your space, and stay cool this summer without breaking the bank.

You would think that after growing up in the hot and humid South, where stepping outside felt like standing in front of an open oven, that I would be used to and unbothered by stagnant summer air at this point. But nope! I still dislike the feeling of sticky clothes and stifling heat, especially in my own home, and think that everyone should have an air conditioner they can rely on.
But some houses don't come with central air and might not allow you to permanently mount something to the wall, which is where things can get complicated. So, to help you stay nice and cool this summer, I'm breaking down the difference between window-mounted and portable AC units and sharing the best deals on both happening right now. Keep scrolling to get the details.
Window-Mounted Air Conditioners
If you can't have a wall-mounted air conditioner, a window unit is a great alternative for a few reasons. They're pretty affordable and easy to install, they don't take up any floor space (which is nice if you're living in a small studio or apartment), they're temporary and they cool rooms efficiently and quickly. The only catch is that they'll also block some of the natural light that comes in your room, and they have to fit the specific dimensions of your window.

We just named Windmill the smartest window AC unit because it's both teched out with cool features and super easy to install. Shoppers praise this brand in glowing reviews for its fast and easy-breezy setup. And this summer, Windmill is giving back to NYC customers with new Eco Rewards, enabling customers to save on their energy bills and earn up to $60 in rewards while making a huge environmental impact. By lowering energy use during peak demand, Windmill users help decrease the risk of overloading New York City's electrical grids, which can cause blackouts, excessive air pollution and higher energy costs.
UNDER 500 SQUARE FEET
These ACs on sale are smaller than most window units, both in size and BTUs, so they're ideal for a smaller room such as a home office or an apartment living room.
OVER 500 SQUARE FEET
If you have a little wiggle room in the budget, these units have slightly more power than the ones above which means they can cool a larger area.
Portable Air Conditioners
If you don't love the idea of a box sitting on your window sill, you might prefer a portable air conditioner. Just as the name suggests, these units typically come on four caster wheels, so you can move them as needed. However, this means that even the most compact unit will take up some of your floor space, and high-powered ones can be pretty pricey. You'll also still need to vent your unit through a window, which means it will have to sit in a corner of your living room or bedroom.
