Best Window Air Conditioner

The $549 LG LW1517IVSM is our pick for the best window air conditioner. What sets it apart from the competition is the use of a dual inverter which means it is the most energy efficient window air conditioner on our list with a 14.7 EER. That could result in 25% energy savings compared to an average air conditioner.

With 14,000 BTU, the LW1517IVSM can cool areas up to 800 square feet while also removing up to 4.5 pints of moisture per hour to control humidity. Other features include 4 speeds, 4 way air deflection, 24 hour timer, remote control, included installation kit, and Wi-Fi. The Wi-Fi connection lets you control this unit remotely thanks to SmartThinQ app technology and it is also works with Alexa and Google Assistant.

One other important aspect of the LG LW1517IVSM is how quiet it is. Again thanks to the dual inverter, on the quietest setting it operates at just 44 decibels which makes it the quietest window air conditioner on our list as well.

Overall the LG LW1517IVSM is the perfect choice for large living spaces or rooms. The only read downside is the initial cost and it might not be the best choice for bedrooms since they are usually much less than 800 square feet.

The LG LW1217ERSM is a step below our first choice, but also comes with a cheaper price of around $403. It received the highest score from the leading consumer magazine for window air conditioners.

At 12,000 BTU the LW1217ERSM can cool rooms up to around 550 square feet while also removing 3.3 pints of moisture per hour. It also can be controlled remotely via the LG SmartThinQ app or with voice control from Alexa or Google Assistant. Other features include 3 speeds, 24 hour timer, and washable air filter.

On the highest setting the noise level is 55 decibels, which is the quietest for any model on our list at its highest setting. However, the minimum decibels is a bit higher than some other models.

Overall the LG LW1217ERSM rates as the best 12000 BTU window air conditioner and is an excellent choice for large rooms up to 550 square feet.

The LW8017ERSM also has a Wi-Fi connection and works with the LG SmartThinQ app, Alexa, and Google Assistant. Other features include 3 cooling and fan speeds, 24 hour timer, remote control, auto-restart, and washable air filter.

Overall we think the LG LW8017ERSM is a great choice for master bedroom window air conditioner or for any space around 340 square feet.

It is also available at Amazon.

If you need an air conditioner for slider or casement windows then you might want to consider the Frigidaire FFRS1022RE which sells for around $570. It is also one of the highest rated models at Home Depot.

It is designed to cool rooms up to 450 square feet while also removing 3 pints of water from the air per hour. It is a bit noisier than the LG models, and is probably not the best choice for a bedroom.

The FFRS1022RE is not smart and has no Wi-Fi connection, but it has all the basic controls you want including 3 different fan speeds, 24 hour timer, thermostat, sleep mode, and remote control. It also has a washable air filter.

Thanks to its vertical design we recommend the Frigidaire FFRS1022RE for slider or casement windows.

The $350 Whirlpool WHAW101BW provides one of the best values in a 10,000 BTU window-mounted air conditioner. It is the cheapest 10,000 BTU model on our list and is quite energy efficient with an EER of 12.1. The biggest drawback is that it is also the loudest unit on our list.

The WHAW101BW lets you control it with its electronic control panel and digital display. There are 3 cooling speeds, 24 hour timer, eco mode, sleep mode, auto-restart, 8 way directional air louvers, and a washable air filter.

Overall the Whirlpool WHAW101BW is a decent option for anyone who wants an affordable 10,000 BTU model and does not care about smart app features.

The cheapest 8000 BTU window air conditioner on our list is the $289 GE AEC08LY. This unit can cool rooms up to 350 square feet with an EER of 11.4. It is a bit louder than some of the other models on this list, especially on the highest setting.

The AEC08LY has Wi-Fi so you can control it via your smart phone. It is also compatible with Alexa, Google Assistant, Apple Homekit, and IFTTT. Other features include 3 cooling and fan speeds, 4-way air direction, energy saver mode, washable air filter, and remote control.

Overall the GE AEC08LY is not quite as good as the LG LW8017ERSM, but it is still a very solid air conditioner that we would not hesitate to recommend to anyone.

The $290 Frigidaire FFRE083ZA1 is another good choice for an 8000 BTU window ac unit. It does not have Wi-Fi like the GE AEC08LY or the LG LW8017ERSM, but it is slightly more efficient than both of them and most people think it is easier to install. As far as just cooling a room, the performance of all 3 is very close.

Some features of the FFRE083ZA1 include digital temp setting, 3 speed fan, 24 hour timer, sleep mode, eco mode, and remote control.

Overall we would not hesitate to recommend the Frigidaire FFRE083ZA1 for anyone who wants to cool a 350 square feet space and does not need to control it from their phone.

Priced at just $219 the LG LW6017R provides a great value for rooms up to 260 square feet. It is also on the quiet side so it makes a good choice for bedrooms.

This unit comes with an installation kit and remote control which makes it easy to use. Other features include 3 speeds, 2-way air deflection, 24 hour timer, washable air filter, and auto-restart.

Overall the LG LW6017R is an outstanding 6000 BTU window air conditioner that we recommend for any room around 250 square feet.

The $173 Frigidaire FFRA051WAE is perhaps the best window air conditioner under $200 and we can see why it is also one of the best selling window air conditioners. It is cheap and quietly and quickly cools small bedrooms or other rooms up to 150 square feet.

Some features of the the FFRA051WAE include mechanical rotary controls, 2 fan speeds, 2-way directional control, washable air filter, and auto-restart.

At just 51.3 decibels in the lowest setting, we think the Frigidaire FFRA051WAE is the perfect choice for small bedrooms. However, it will not work well for larger spaces.

The cheapest window air conditioner to make our list is the GE AEL05LX with a price of just $149. This 5000 BTU model will work in rooms up to 150 square feet. It is a bit noisy with the noise level ranging from 55-59 decibels.

Some features of the AEL05LX include 2 cooling and 2 fan speeds, mechanical thermostat, drain in back of unit, and included installation kit.

Overall we recommend GE AEL05LX if price is your biggest concern and you need the most affordable window air conditioner for a small room.

Last time we checked the GE AEL05LX was not in stock. So as an alternative you might also consider the Toshiba RAC-WK0512CMRU which has comparable specs and sells for the same price.
