LG is a trusted brand in the electronics space. So, it’s no surprise that they have made one of the best AC units on the market. The LG LW1216ER Air Conditioner is designed for large rooms (up to 550 square feet) and has an impressive cooling power of 12,000BTU. Unlike some other AC units on the market, this product doesn’t provide any heating power, so don’t buy it if you need an all-season solution. 

Using the front and side vents, this unit offers four-way air direction, which allows it to cool down a room much quicker. Just mount it on an appropriate window and control the temperature using the remote control. Users will also appreciate the Saver function, which makes the most of the 12.1 energy efficiency ratio. Plus, it has a 24-hour on/off timer and LG’s patented anti-corrosion coating that lowers the need for frequent services. Be sure to also browse our list of the best-selling small air conditioners.

If you’re looking for an all-in-one machine, you’ve got to consider the MIDEA MAW10R1BWT. This brand is known in the air conditioner space for their innovative designs and solutions, and that’s certainly the case in this model’s 3-in-1 functionality. Depending on what you need most in your home, you can use it as a dehumidifier, air conditioner, or just a plain old fan. This allows you to find the perfect solution, save money, and get the environment just right in your home. 

It offers 10,000 BTU of cooling power, making it suitable for rooms of up to 450 square feet. You also need to have a window that’s big enough to accommodate the machine (all of the necessary mounting accessories are included). One thing that users love about the MIDEA MAW10R1BWT is the intuitive remote control that lets you control the temperature and air quality in the room using different modes including sleep, 24hr timer, fast cool, and ECO energy saver.

The first rule of thumb: These units may say they only cover a certain area, like Koldfront WTC 8,000 BTUs model, which says it covers up to 350 square feet, but 8,000 BTUs can cover a lot of ground. You just have to be smart not to leave too many heat-drawing elements in your room, like chargers and other constantly plugged-in devices.

Koldfront offers a median price while giving you three fan speeds, four operation modes, and an eight-button remote control that allows you to control the numerous features. One nifty bit about this unit is the additional feature of a heater. It provides up to 3,500 BTUs of heat, which isn’t going to do much in any normal-sized room, but it’s great for providing supplemental heat.

LG produces some of the best appliances and general-use electronics in the world, and they don’t stop at smart TVs and routers. This LG unit offers nearly 10K BTUs, so you can turn your studio apartment into an igloo in just a few hours. The unit is small enough to install in the space between your windowsill and your baseboards. Not everyone wants their unit sitting high above the television or being difficult to access, and this unit is perfect for that demographic.

Keep in mind that the unit is small, but definitely not lightweight. This bad boy weighs a staggering 80 pounds and will require a helping hand to get installed. Once it’s installed, you’ll get three different cooling options, three fan speeds, and a six-button remote control, so you can leave it by the door and flick it on before you even kick your shoes off after work. You can also use the built-in timer features to cool the room down before you even walk in the door.

Who even knew Keystone was still pushing out products? This wall unit AC comes with everything you could want: 12K BTUs for a deep chill, three cooling speeds, three fan options, and the coolest feature of all — a temperature-sensing LCD remote control. Yes — your remote control sends information to your AC and uses that to cool down your room.

This unit weighs nearly 80 pounds, so you’ll want an extra pair of hands when you’re installing it. The good thing is it’s a compact model, so you’ll be able to install it under windowsills and in other optimal points of the home — it doesn’t just have to be high up on the wall. You’ll have to purchase your wall sleeve separately.
