1. LG LW2217IVSM (22000 BTU)

First up, the LG LW2217IVSM is an outstanding window air conditioner with inverter technology. Not only is it impressively powerful providing 22000 BTUs, but you’ll also appreciate its ability to cool up to 1300 square feet. This dual inverter saves on average up to 25% of your energy bill. Let alone, dual inverters save up to 40% more energy than the Energy Star Certified requirements. You’ll appreciate its softer than usual 44dB noise level, as well.

With air coming in four different directions, it’s able to cool the room evenly. It also comes with a useful remote control. With integrated LG ThinkQ technology, you can control the unit with a phone app regardless of your location. Overall, this air conditioner is an amazing choice and we highly recommend it!

Users Say: “As advertised. Quiet, cool efficiently, synced to the network without an issue. We have this unit at our farmhouse which is a second gone for us. It’s 3:30 hrs from our main home. I turn the unit on remotely when we leave gone and the entire farmhouse is cool by the time we get there. We have several floor fans that are also on smart plugs that distribute the cool air efficiently.”

2. Midea U (8,000BTU)

Coming in three different sizes, you can get the Midea U with either 8000, 10000, or 12000 BTUs. This window air conditioner provides advanced DC inverter technology. Not only is it remarkably quiet at 42dB, but it also saves more than 35% energy. Another beneficial feature is its U-shape construction which enables your window to open. 

With built-in smart features, this unit can also be controlled anywhere with the MideaAir app. It’s also compatible with Alexa or Google Assistant voice command. Overall, it’s an excellent choice if you’re looking only to cool a single room!

Users Say: “First things first, I wanted to know details on wattage usage of the 8000 BTU unit, so here it is now that I have one of these: ~700 watts on high cool, ~500 watts on medium cool, ~200-300 watts on low cool. It’s very quiet, easy to install, well put together and I simply like everything except 1: I wish the fan would blow harder on each setting without increasing wattage much ( easy modification for a manufacturer like them). Let’s just say a swamp cooler might be a better option overall for low power usage but both are a nice option as well, just pricey. For those who don’t know Midea produces a lot of your regular brand parts and has been around for over 40 years.”

3. LG LW1517IVSM (14,000 BTU)

Next up, the LG LW1517IVSM is an excellent dual inverter window air conditioner for the money. It’s primarily designed to cool a room up to 800 square feet. You’ll also appreciate that it’s 25% more energy efficient than the minimum Energy Star Certified system. On top of that, you’ll enjoy the four separate cooling speeds, as well. 

This unit has a built-in auto-restart feature that turns the air conditioner back on in case of a power outage. Compared to the moderately high 14,000 BTUs, it’s reasonably priced. Be sure to check out the reviews below!

Users Say: “Very quiet even when it is running full out. Looks better than every other window a/c out there. Simple to install and just works great. The “Smart ThinQ” however is anything but smart. Although LG likes to blame it on the location of your wifi (mine is 10′ from the unit) it works most of the time at best as it takes a while to load the app and signs me out every once in a while which is unnecessary. I do turn it on when leaving work from my car (on a cellular network) so it is icy cool when I arrive at home. It does work lots of the time. The remote works well and does everything I need it to do. For its cooling capacity and super quiet this is the best 14,000 BTU window a/c you can buy.”

Tech Specs & Details

  • Size: 27.95 x 27.28 x 20.67
  • 4 Fan Speeds
  • SmartThinQ Technology: Compatible with Alexa & Google Assistant
  • Inverter
  • Area Coverage: 800 Square Feet

4. Midea U (12,000BTU)

The Midea U is a remarkable inverter window air conditioner. Providing 12,000 BTUs, it’s exceptionally powerful. This system is very quiet with a 42dB noise level, provides smart features with its MideaAir app, saves 35% energy, and compatible with Alexa/Google Assistant voice commands. It’s an amazing bang for the buck!

Users Say: “The unit is very quiet as advertised, at least 60% if not more, quieter than the 12k LG that it replaced. Install was tricky because we have Andersen windows. I had to add blocking screwed into the windowsill to make the sash align with the U. A bit of trial and error but it’s in and very secure. I will have to add some foam insulation to cover some gaps as well. We will put it to the test this weekend and report back. UPDATE: We ran the Midea 12 K unit this past weekend and it was phenomenal, super quiet, plenty of cold air, and easy to use. Early days yet, but we look forward to a hot summer outside and cool quiet comfort inside. Updated update, Flawless operation! Can’t recommend highly enough!”

5. LG LW1817IVSM (18,000 BTU)

Last but not least, the LG LW1817IVSM is another fantastic value. It provides 18,000BTUs which effortlessly cools areas up to 1000 square feet. With LG SmartThinQ, it’s al compatible with both Google-Assistant and Alexa. Another essential benefit is its quiet noise level of 44dB. Lastly, its auto-restart feature comes in handy, as well!

Users Say: “Purchased last year when summer started in Boston, this unit has proved its worth. Can set the desired temperature by degree, 3 different fan settings. It is indeed very quiet, easily not noticeable on the lowest fan setting, but powerful enough to cool the room into the 60s deg F range if desired on the higher fan settings. It was quite heavy and a feat to install by myself — would recommend two people, as the manufacturer suggested. It is indeed energy efficient too — my monthly energy costs were cut in half compared to the prior year when I replaced two weaker window A/C units with this beast. The 240V requirement may be a deal-breaker for most. I got around this by constructing an appropriately rated extension cable to connect two out-of-phase 120V outlets to create a 240V receptacle (can read about on YouTube, very dangerous if not done correctly) — mine has been working well for a year now. Would buy again!”
