5 great window-mounted air conditioners

1. LG LW8016ER ($209)

You can pay for a quieter unit, but this 8,000-BTU air conditioner is the best in its class. Efficient and "quietish," it emits a pleasant low hum, directs air well, and cools up to 340 square feet. It also has a fresh-air vent and removable drain plug. Buy it at Amazon.

2. Haier ESAQ406PT-H ($300)

This excellent 6,000-BTU AC produces a mere 43.4 decibels — 11.5 quieter than the average unit of the same size — because a buffer around the compressor muffles vibrations. Perfect for a bedroom, it cools up to 250 square feet. Buy it at Amazon.

3. GE Energy Star AEC08LX ($250)

Like the other units in GE's new line of smart air conditioners, this 8,000-BTU box pairs with Google Assistant, Amazon Alexa, or Apple HomeKit. You can adjust the temperature and turn it on or off using an app or vocal commands. Buy it at Home Depot.

4. Frigidaire Cool Connect FGRC1044T1 ($400)

Window-mounted air conditioners are usually ugly things, but not the 10,000-BTU Cool Connect. This sleek and efficient AC can also be controlled remotely via a smartphone and cools up to 450 square feet. Buy it at Amazon.

5. HomeLabs Window AC ($135)

If you're on a budget and you're looking for something simple, consider this top-rated Amazon pick. The 5,000-BTU unit cools just 150 square feet, but it's all you'll need to change the whole atmosphere in a small, hot room. Buy it at Amazon.
