Thanks to the climate changes and rising heat across the world, gone are the days when air conditioners were deemed as luxury items. Nowadays, an air conditioner has become a must-have appliance for every home. With that said, if you’re in the market for a quality air conditioner for your home or office, you can’t do better than the best LG air conditioner. Having churned out a significant number of high-performing air conditioners over the years, LG is probably now the world’s most reliable brand when it comes to air conditioners.
To help you out in your shopping, we’ve reviewed 15 LG ACs and chose five of the best models at the moment. While each of our picks guarantees to provide great performance, the king of them all is the LG LP0818WNR Portable Air Conditioner. Admittedly, this model is below some of our other picks in terms of pure power, but the advanced features it comes with makeup for the small BTU output.
As always, we considered certain factors for our selections, some of which include the type, BTUs, coverage area, and dimensions. Depending on where and how you want to be using the unit, it’s important to consider the type and dimensions. Whereas, the BTUs and coverage area determine the efficiency and power of the unit. Lastly, we’ve stuck with the usual pattern for the structure – the comparison table, a review section, and a buying guide.
If you’re in the market for a unit that provides adaptability and portability in smaller spaces while maintaining the high performance of a larger unit, you can’t look beyond the LG LP0818WNR Air Conditioner. Apparently, what this unit lacks in size, it makes up for it in functional and intricate features. And apart from being portable, it also comes in an ergonomic design, featuring side handles to easily move or carry it. That apart, it also comes with a four-wheel construction, so whether you choose to carry it or wheel it from one room to another, everything is possible.
In terms of coverage area, the AC unit is capable of cooling a room measuring 200 square feet in size. However, that makes it only suitable for small rooms. Moving on, the design includes a self-evaporative technological system, which guarantees that the air conditioner unit efficiently cools the air at all times while keeping water waste and energy consumption to the minimum. Whereas, apart from being an air conditioner, this product also serves as a dehumidifier and a fan. For its dehumidification power, it’s capable of purifying a room of up to 200 square feet at a rate of 1.27 kilograms per hour.
For clarity and convenience, the portable unit is equipped with a control panel and LED display, along with a remote control that allows you to adjust the settings of the device right from across the room. On the display panel or the remote control, you can control the temperature, switch between the three operating modes, and set the 24-hour on/off timer. In general, this air conditioner from LG is probably the best cooling appliance you can find on the market today, especially if you have a small space to cool.
Packing 14,000 BTU and having a coverage capacity of up to 800 square feet, the LG Dual Inverter LG LW1517IVSM Window Air Conditioner is the go-to option if you are in the market for a powerful unit that can effectively cool your large room. While the powerful nature of this unit has its many advantages, the only downside with it is that its installation is more difficult than other, smaller units. With the portable models, only one person can carry out their installation. That may, however, be impossible with this heavy-duty model.
Once it’s installed though, only few models can better it in terms of power and general performance. It’s designed to cover a space of up to 800 square feet, which is the largest on this list by a long mile. And despite its powerful operation, the unit is up to 25 percent more energy-efficient than the minimum Energy Star certification requirement, thanks to the incorporated DUAL Inverter technology. Impressively, this unit, for all its power, has a quiet operation, which is due to the included dual inverter compressor and special BLDC motor.
This product also offers SmartThinQ technology, which allows users to remotely control it via a smartphone app. It’s also worth mentioning that it’s compatible with Amazon Alexa and Google Assistant, which means you can adjust the settings with only your voice. With everything on offer, this heavy-duty unit from LG is the perfect option if you are looking to cool a larger space.
If you are in search of a perfect model to cool multiple rooms without needing to install a couple of window AC units, the LG Dual Inverter Technology Air Conditioner should be your go-to option. Featuring Dual Inverter technology, this model consumes less energy than units with conventional cooling systems. Besides, its compressor with dual rotors results in faster cooling, low operational noise, greater stability, and high energy savings. With its 14,000 BTUs, you can be guaranteed that the AC unit is powerful enough for whatever is thrown at it.
In terms of coverage area, it is capable of cooling an area of up to 500 square feet in size, which is remarkable. Its many impressive features include a dual oscillating fan assembly and a control panel, alongside power buttons. Furthermore, this unit offers you two different models to cool the air – Dry Fan and cool operating mode. The design also comprises of the Wi-Fi, timer, and sleep indicators. The sleep feature shuts the unit down after eight hours, so that the unit won’t overheat.
It’s also worth adding that this model comes with an LCD, which displays the fan speed, temperature, and timer settings. Plus, the product is compatible with Google Assistant and Alexa, so you can control it from your phone. However, the phone application is somewhat too slow, which may be the only issue. For easy mobility, the unit is equipped with four casters, which make it easy to roll it over thick carpeting. Also, it’s a plus that it has a quiet operation, so you’re guaranteed to have an enjoyable night.
Certainly, LG has a reputation for producing sleek, modern air conditioners over the years. However, the LG LW8016ER Air Conditioner is a bit different, trading aesthetics for efficacy, which results in a unit that’s both easy and simple to operate. In terms of functionality, this product packs quite a punch, with its 8,000 BTU. However, its BTU output isn’t its selling point as it’s below what is offered by most top-of-the-line AC units. Nonetheless, the fact that your lights may dim a bit when the compressor starts working and the not so impressive design of the unit are the only drawbacks you will find with this product.
Other than that, it comes with everything to marvel you, including three fan settings, a quick operation, and a dehumidification capability of 2.2 pints per hour. When it comes to coverage area, this unit can cool spaces up to 340 square feet, making it ideal for most homes. It’s also fully programmable, features a 24-hour timer and includes a remote control for utmost convenience. Meanwhile, there’s a unique energy-saving function that will help keep your utility bills down. And apart from being incredibly functional, this unit is also reliable and durable. It boasts a gold anti-corrosion coating, which somewhat guarantees its longevity.
In addition, the unit features a feature that kicks in when there is a power outage, making it turn itself on immediately the power is restored. With this, you will not wake up feeling stuffy in the morning. Although the aesthetic design of the AC unit is nothing to write home about, its great performance and functionality will. It’s a wonderful unit will only a few imperfections.
While the LG LW5016 5,000 BTU Window Air Conditioner is the lowest-rated air conditioner on this list, that doesn’t make it useless because it’s actually functional. With its coverage area of up to 150 square feet, this model is especially suitable for you if you are looking for something to cool your small room or office space. In terms of BTU output, it delivers 5,000 BTUs, which should be enough for a space that’s not larger than 150 square feet. Admittedly, this model is not the most powerful or the most functional, but you can’t deny that it does what it’s advertised to do.
Furthermore, it doubles as a dehumidifier, with a dehumidification capacity of 1.3 pints per hour. With its dehumidification ability, it’s evident that this unit from LG is as versatile as it gets and can help you maintain a cool and comfortable atmosphere during the hot summer season. It also comes with two cooling/fan speeds, which makes it more flexible than some other models in its category. However, this machine doesn’t come with many bells and whistles of more sophisticated models, but that shouldn’t come as a surprise considering its very affordable price.
Despite coming at a very affordable price, this unit sports a durable construction, so you can rest assured that it will serve you for many years. For its installation, there’s an installation kit in the package, which is easy to use and completely takes the hassle out of installation. In general, this model is a decent unit, but if advanced features and powerful operation is what you’re looking for, continue your search.

Things to Consider
It’s important to read reviews when looking to invest in something as important as an AC, but we don’t think reviews are enough to hinge your decision on. To make the best decision, we encourage you to read the comprehensive guide we have put together below.
While LG is one of the most popular companies in the world, most people only know them for their TVs. If you are in the process of choosing between LG and some other brands in your search for the right AC unit for your needs, below are some reasons why LG is the best on the market.
If you are familiar at all with the world of electronics and home appliances, then you should know how reputable LG is. Without a doubt, the company is one of the most reliable brands when it comes to home appliances. For instance, they are one of the first options that come to mind when we’re in search of reliable televisions, kitchen appliances, and washing machines. Fortunately, they are equally brilliant in the manufacturing of reliable and high-performing air conditioners. It also helps that they back their air conditioners with long-term warranties.
LG air conditioners usually come with energy-saving features, so they save you lots of money that would have otherwise been spend on energy bills. The Energy Efficiency Ration of an AC unit measures the efficiency. The higher the energy efficiency ratio, the more efficient the product will be. Therefore, this is a significant reason why you should go for an LG air conditioner when choosing the right AC brand for your home or office.
Most giant brands are known for their modern inventions and top-of-the-line features, and there’s no exception with LG and their air conditioners. Expectedly, LG usually incorporates modern features into their air conditioners, which make them stand out amongst their rivals. Some unique features incorporated into some AC units on our list include Dual Inverter technology and SmartThinQ technology.
Features to consider when choosing an LG air conditioner
Before picking your favorite air conditioner from LG, there are different factors you must take into consideration to make sure that you get the best model available. The following are some important factors you must take into account when trying to decide between the different LG models on the market.
Air conditioners have different types, with the window and portable types being the most popular. Normally, window units are more popular, thanks to their ease of installation and affordability. However, some apartments and homes have unusual window shapes that may not accommodate window units. Portable units, on the other hand, are great because you can easily move them from one room to the other, but they need more maintenance and are not as efficient.
While split or built-in systems provide a more permanent solution, they can be really expensive and need professional installation. The LG LW1517IVSM Air Conditioner is an example of an excellent window-type AC unit on our list.
Regarding air conditioners, BTU is an internationally recognized measure for the amount of heat that can be removed by an AC unit from a particular space. Thus, when you are buying an LG AC unit, we advise you to find out the BTU of the machine. For example, a unit with a BTU rating of 5,000 can cool a space of up to 150 square feet, as we might have noticed with the LG LW5016 Air Conditioner’s BTU rating and coverage capacity.
It’s also important to consider the amount of area that the AC unit you intend to buy can cool. Of course, this usually depends on the size of your room or office, so logically, the first thing you will need to figure out is the size of the space you intend to cool. With its ability to cool up to 800 square feet, the LG LW1517IVSM Air Conditioner has the biggest capacity in terms of coverage area.
Cooling and fan speeds
Another factor you may want to consider is the number of fan speeds on your unit. Having a range of cooling/fan speeds can be useful in circulating air at different rates and providing a cooling effect as well. As a rule of thumb, the best air conditioners should come with three-speed settings. That doesn’t mean those with fewer speeds won’t work though, it may just depend on your needs.
If you intend to use your AC unit in your living room or bedroom, then you need to mind how noisy it is. While appliances’ noise level is usually measured in decibels, most people don’t have an idea of how loud 40 decibels are, for example, probably because most people don’t use this measurement in their daily lives. Therefore, it can be a bit complicated to choose a unit with quiet operation.
Generally, a regular AC unit works between 40 and 60 decibels. Televisions, for reference, operate at about 60 decibels, and normal conversation is around 50 decibels. Thus, if you purchase an AC unit that works around 60 decibels, it’s likely to interfere with your TV show or conversations. Some of the quietest models on our list include the LG Dual Inverter Technology Air Conditioner and the LG LW1517IVSM Air Conditioner.
Dimensions and weight
Dimensions and weight are also important when choosing the best air conditioner for your needs. If you know you want to be moving the unit from one room to the other, then you must consider a portable unit that can be easily moved. Here, you’ve got to keep both dimensions and weight in mind as both usually contribute to portability. However, if you know you’re not likely to be moving your unit around a lot, then you could choose the largest and the heaviest models. But you’ve still got to know that heavier units are usually difficult to install.
Most AC units come with a warranty, so there’s no need for you to worry. These warranties usually cover anywhere from one to 15 years. Make sure you check the terms of the warranty though as some warranties come with different limitations.
Typically, window models are fairly loud since they usually rumble against the window when operating. Portable models, on the other hand, are less noisy when operating, with some even being as quiet as a fan.
When the summer months arrive, you need the best cooling system to maintain optimum comfort in your home. While the LG LP0818WNR Air Conditioner neither possesses the highest BTU output nor cover the largest area, it’s still our Editor’s Choice, for being super-efficient and coming with a range of advanced features. Basically, this portable model comes with a bit of everything and we’re loving it.
With that decided, the LG LW1517IVSM Air Conditioner and the LG Dual Inverter Technology Air Conditioner take the second and third spots respectively. Each one has a BTU rating of 14,000, which means they’re both powerful enough for cooling large areas and multiple rooms. However, the exact coverage area is where the LG LW1517IVSM edges its rival as it’s rated to cover up to 800 square feet compared to its rival’s 500 square feet coverage.
