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 AC offers four-way air direction, which allows it to cool down a room much quicker. Simply mount it on an appropriate window and control the temperature using the remote control. Users will benefit from 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.

If you’re looking for an all-in-one machine, you’ve got to consider the MIDEA MAW10R1BWT. This brand is known in the window air conditioner space for their innovative designs and solutions. The reason we’ve picked this product is its 3-in-1 functionality. Depending on what you need most in your home, you can choose from a dehumidifier, air conditioning, and fan-only modes. 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 mode, 24hr timer, fast cool, and ECO energy saver.

From the brand you’ve (probably) never heard of comes a cost-effective, small wall-mount AC. It’s Energy Star rating puts it up a notch, and being under 65 pounds makes for easier carrying and install. If you’re man enough, you can put this in yourself, but don’t mess up your back.

Take advantage of the smaller, more narrow size by putting it in tight spaces, whether it’s between window frames and corners or beneath the sill and above the baseboards. With less weight and a smaller build, you can let your creativity run wild with where to put it. Above the stove, cooling down the mancave made out of a shed outside—the choice is yours, and the power is fantastic.

Set it to auto, and let it learn how you operate, or put on a 24-hour timer and have the room icy cold for your triumphant return from work the next day. How you use Friedrich Chill Series is anybody’s guess, but when you use it, it’s a whole different ballgame. This unit chills the room fairy quickly, despite only being 8,000 BTUs of power. Save money and cool down the room with a space-saving, energy efficient model.

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 numerous features. One nifty bit about this unit, which helped it earn our top spot, 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 to supplement heat (especially if you’re using a rather small space heater and can’t afford a larger unit).

This air conditioner is great for living rooms and medium-sized bedrooms. Use the timer feature to set it up to chill the room while you’re driving home from work. Apart from that, this model is also compatible with other sleeves. If you’ve ever owned a Koldfront air conditioner in the past, you might be able to recycle that old sleeve for this unit, if need be. Overall, it’s an excellent value with tons of reliable features, and is lightweight/small enough to install on your own without requiring additional help.

Much like it’s younger brother that snagged the first spot, this ultra-powerful Koldfront WTC12001 12,000 BTUs air conditioner is perfect to cool large spaces, and quickly take the blistering heat out of small rooms. Seriously: Power this bad boy on in a 9 X 9 room, and you’ll be frozen in place before you can reach the dial (which is okay, because it comes with a digital remote).

The manufacturer says you can cool up to 450 square feet, but in reality, you could use this in a large area like a conjoined living room/dining room, and the whole family would be putting on mittens to hold their cups of hot coffee in no time. This comes with three fan speeds, four different operation modes, and comes with a fantastic energy rating.

You get buttons galore and an eight-button remote—just enough that you can master it in an afternoon, not too many that you’re scratching your head just to turn the fan on. The wonderful thing about these units is that just because it can work up to 12,000 BTUs doesn’t mean you have to push it that far. Putting this down three degrees from the room temperature will ensure that you get to a comfortable level in a short amount of time.

LG produces some of the best appliances and general-use electronics in the world, and they don’t stop at televisions and routers. This LG LT 9,800 BTUs comes with nearly 10K BTUs, so you can turn your studio apartment into an igloo in just a couple of hours. This unit is small enough that you can install it 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 does the trick.

Though small and compact, this unit weight a staggering eighty pounds, and will require a helping hand to get installed. You 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. Then again, you could use the built-in timer features to cool the room down before you even walk in the door without wasting a ton of electricity.

Dehumidified water leaks out of the back without aid, so you don’t have to worry about changing a drip pan. One downside is that you do need to order the sleeve separately, so don’t purchase this expecting it to come with everything you need. The last thing you want to do is carve a hole in the wall, open it up to the outside world, and then have to push the two-day delivery option on a sleeve. It cools down your room quickly without breaking the bank, all with an excellent Energy Star rating.

10K BTUs are more than enough to get the task done. Returning from a dash around the block in the blistering heat? Set the timer to chill the room for you without icing your wallet. You get a formidable amount of power behind a median price, all wrapped in a galvanized cabinet with a self-draining part.

Garrison R-410A even comes with a touch of smart technology embedded, called the Follow Me feature that understands the temperature of the room, and takes control of your choices to keep it adjusted to your specific comfort level. Five modes give you optimal control when you want it, including a sleep function (and you can set the timer up to 24 hours).

This 220V, seventy-pound unit has a thermostat included, but it doesn’t appear to come with the sleeve. It’s a quiet unit that will allow you to sleep without worry, though it will require a two-man team to move it into place properly. If you’re looking for a model that you can install in a low space, this is your guy—self-evaporative technology means you’re not going to kill the grass directly beneath the unit outside, either.

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.

The great thing about the Follow Me feature is that you can leave the remote in the middle of the coffee table for when you have large groups of guests over—have your AC automatically contour the BTU output to how many guests you have based on how quickly the temperature rises in the room. Keep in mind that if you bring it with you when you cook and place it on the counter, it could get false readings.
