The summer heat has already arrived for much of the U.S., and everyone is doing their best to keep cool. Fans are the energy-efficient go-to when it’s under 90°F, but at that temperature and hotter they actually exacerbate the effects of heat stress—at those temperatures, air conditioning is your only option.

Things are only going to get hotter from here, so if you don’t already have a new A/C it’s a great time to grab one.

Here’s a list of the most popular and trusted air conditioners you can buy on Amazon.

1. Midea MAW12V1QWT Window Air Conditioner

Reviews: 9,933

Rating: 4.5

If you haven’t used a U-shaped air conditioner before, you’re in for a treat. Air conditioners with this design have a slit down their middle, which allows you to close the window much further than you normally would. This better secures the air conditioner in place and significantly lowers the noise from operation.

The Midea MAW12V1QWT is one of the highest-rated air conditioners on Amazon, with a very high 4.5 stars after almost 10,000 reviews. It comes in 8,000, 10,000, and 12,000 BTU versions and features a standard array of smart features you can access from its companion app.

Those who love their Midea MAW12V1QWT praise its quiet operation and how efficiently it cools rooms. The only minor complaints we could find involve the installation being more difficult than expected.

2. GE AHEK08AC Window Air Conditioner

Reviews: 3,860

Rating: 4.5

This GE features a traditional window A/C design but incorporates smart features to allow remote control via a smartphone app.

While it’s not the quietest option on the list, users seemed to love it regardless, primarily due to the fast rate at which it was able to cool down a room.
