It has a U-shaped design that gives you the flexibility to open and close your window while the unit’s installed, which isn’t possible with many other window air conditioners. And since the compressor (aka the loud part of the unit) is blocked by your window, the Midea U-Shaped air conditioner is nine times quieter than traditional models, according to the brand. You’ll have no problem hearing your TV without turning the volume up. “Even cranked to max, the unit is whisper-quiet inside—about as loud as a box or stand fan set to low,” wrote a customer. To buy: From $359; amazon.com. Midea’s window air conditioner usually comes in three different sizes—all of which are Energy Star certified, but the 8,000 BTU and 12,000 BTU versions are the two back in stock (the 10,000 BTU model is still sold out). According to Energy Star, an air conditioner with 8,000 BTUs works in rooms ranging from 300 to 350 square feet, while a 12,000 BTU model works for rooms ranging from 450 to 550 square feet. “I looked at many window units before I finally made the leap and bought this Midea U unit,” a shopper said. “This 8,000 BTU unit is in my bedroom and it cools my entire apartment without straining. A humid 80 degree day is nothing.”
