Buyers Guide & Information

LG AC Reviews

We have independently reviewed, rated and compared the LG Air conditioner range.

According to Cole Porter’s timeless classic ‘Too Darn Hot,’ quality of life is compromised pretty spectacularly when the temperature rises! We all prefer to keep our cool these days.

In fact, according to statistics, 84 percent of all homes in the United States have some air conditioning. Interesting fact: it’s more common for houses in the US to have an air conditioning unit than a garage, a dining room, or a dishwasher.

These essential appliances make home life much more pleasant for everyone in warmer climes, hence their priority on the list of home comforts. LG offer a wide range of products to keep you cool as a cucumber whether you live in a small apartment or a large family home.

Key Considerations Before Buying

British Thermal Units (BTU) Explained

A British Thermal Unit (BTU) is a precise measurement that represents the amount of energy required to change the temperature a single pound of water by 1 degree Fahrenheit above or below the current temperature. It’s the most commonly used way to measure the effectiveness of heating, ventilation, and air conditioning systems.

Nearly all air conditioners have a tested BTU rating. A higher BTU rating means that the air conditioner is capable of cooling a larger area more effectively. LG air conditioners include products suitable for both cooling both large and small spaces.

Cooling Area

Though it may be tempting to think that a higher number of BTUs will cool your room more effectively and quickly, it won’t be energy efficient if it’s the wrong size for the space. A potent air conditioner with more BTUs than necessary will cool the area quickly. The problem is that the unit will then cycle on and off frequently throughout the day in short bursts to maintain this temperature. This can damage internal components and shorten the operational life of the AC.

Here’s a guide to help you to calculate the optimum number of BTUs for the space you wish to cool:

More Features of LG Portable AC Units

Advances in technology have made controlling your AC and making it as energy efficient as possible so much easier. Less energy equates to less cost to you on expensive electricity and less burden on the environment, so it’s a win-win to use features such as smart technology which are now available with many AC units.

Some LG products allow you to stay cool and in control with their LG SmartThinQ® technology. It lets you control your LG air conditioner remotely, so you can start or stop cooling, change the mode, or set the temperature from anywhere. Even if smart technology isn’t for you, you can still benefit from the many other features offered by LG such as remote control operation, energy saving features which keep the temperature at a set level without working constantly and variable fan speeds to control the noise level and rate of cooling.

With their wide range of air conditioning products, including portable, wall-mounted and window-mounted options, LG aims to keep you cool and comfortable — even when Mother Nature turns up the heat. LG air conditioners give you the power and technology you need to maintain the perfect temperature inside your home all year round, no matter how hot and steamy it gets outside.

8 Best LG Air Conditioners Reviewed

1. LG LP0818WNR

Specification Summary
Type of AC Portable
BTU 8,000
Cooling Area 200 sq. ft.
EER 11.6
Voltage 115V

If you’re looking for a portable LG, the LP0818WNR is a solid choice. This portable AC can cool a space up to 200 square feet, and while it’s cooling, it also works to draw moisture from the air. It uses a top inclined air discharge system with auto-swing louvers that actively work to eliminate hot spots from the room.

The dehumidification feature eliminates up to 4.9 pints of water from the air per hour. The rolling caster wheels make this the perfect climate control system when you’re on the go, and the sleek contemporary aesthetics look great in any room. It weighs about 60 pounds, but the wheel system counteracts the heavy design.

This LG is built with 8,000 BTU cooling power, and even with the powerful performance, you can always count on quiet operation. On the high setting, the noise level is about 53 decibels, and on low, it’s 50 decibels. This makes it a great addition to a bedroom since it won’t keep you up at night.

In terms of cooling features, the LP0818WNR comes with 2 fan speeds, 2-way air deflection, a 24-hour timer, and easily adjustable temperature controls. All of this can be controlled from either the device’s panel or the included LCD remote. You can plug it into a standard 115V, and there’s an included installation kit that makes setup easy for anyone. On top of all this, maintenance is easy, thanks to the washable air filter.

One thing that isn’t ideal for an 8,000 BTU is that it comes with just 2 fan speeds. There are plenty of 8,000 BTU portable units that offer 3 speeds, but this one only has a High and Low setting. But for the price and the cooling performance, this small flaw is easy to overlook.

2. LG LP1419IVSM

Specification Summary
Type of AC Portable
BTU 14,000
Cooling Area 500 sq. ft.
EER 12.0
Voltage 115V

Another portable LG to consider is the LP1419IVSM. This model is significantly more costly than the LP0818WNR model, but there are quite a few reasons for this. First off, the LP1419IVSM uses dual inverter technology for highly efficient performance.

LG says that “portable air conditioners with DUAL Inverter Compressor provide cool temperatures with up to 40% more energy savings.”

Even though the cost is high initially, you’re looking at a lot of energy savings over time – up to 40%. Secondly, this unit can cool a space up to 500 square feet, which is more than twice the cooling area of the last LG. It has a cooling power of 14,000 BTU, and while it cools, it dehumidifies the air up to 6.8 pints per hour.

This LG is all about maximum cooling for maximum comfort. LG knows that comfort isn’t just about staying cool, but also about quiet operation. This is considered a low noise level unit that, and it’s always working to eliminate unnecessary noise so that you’ll barely notice it’s running. On the low setting, it has a dBA rating of 44, which is about as loud as a quiet library.

It’s not only advanced in energy efficiency and quiet operation, but also in cooling performance. It’s built with a convenient Sleep mode that gradually raises the temperature throughout the night, but the best part of all is the Smart technology. This unit pairs with the SmartThinQ app by LG so that you can control your home’s climate from anywhere, even when you’re away from the house. You can also control it with your Alexa or Google Assistant device.

3. LG LP0817WSR

Specification Summary
Type of AC Portable
BTU 8,000
Cooling Area 200 sq. ft.
EER 9.0
Voltage 115V

The LP0817WSR is considered a midrange LP portable AC. It’s a great choice if you’ve got some money to spend, but you’re still not wanting to break the bank. It’s an 8,000 BTU unit that can cool a room with dimensions up to 200 square feet. There’s barely any installation needed other than some window ducting, but the included window installation kit will help with this.

Similar to other LGs, this one uses a top inclined air discharge design with automatic swinging louvers so that you never have to worry about hot spots throughout the room. And just like other LG portable ACs, the LP0817WSR features a sleek contemporary design that blends in well with any style room décor.

The 3-in-1 operation is what users seem to love most about the LP0817WSR. In LG’s product description, the company says that “the cool mode is ideal for powerful cooling and dehumidifying in hot days. In fan mode, the fan circulates air while the dry mode is ideal for rainy and damp days.” The dehumidification feature eliminates nearly 2 pints of water from the air per hour. It also comes with a 24-hour timer, auto restart function, and a Sleep mode.

The main downside is that this is not the most energy efficient portable LG AC on the market. Unlike the LP1419IVSM model, this one isn’t designed to maximize your energy savings by up to 40%. The EER is 9.0, which is still adequate, but it’s definitely not the most efficient unit on this list of LGs – especially when compared to the 12.0 EER of the LP1419IVSM.

4. LG LP1417GSR

Specification Summary
Type of AC Portable
BTU 14,000
Cooling Area 500 sq. ft.
EER 12.0
Voltage 115V

The LG LP1417GSR is another portable unit that is designed for large spaces up to 500 square feet. It has a BTU rating of 14,000 with a cooling performance that is very similar to the LP1419IVSM. This one is a bit cheaper than the LP1419IVSM, which is also a 14,000 BTU unit and offers the same cooling area. The main reason for the lower price tag is that it does not feature Smart technology, which means you won’t be able to control the unit with an app.

Even though it doesn’t offer Smart operation, there’s a lot going for the LP1417GSR. Aside from the fact that it can handle cooling an ample space, it also significantly reduces your home’s humidity by removing up to 3.1 pints of water from the air per hour. Similar to all other portable LGs, it uses the top inclined air discharge design to eliminate hot spots from the room.

It comes with a 24-hour timer, an auto-restart function for power outages, easy up/down temperature adjustments, sleep mode, and a full-featured remote to control it all. It operates with the standard 115V outlet and comes with a 6-ft power cord for simple installation. You’ll need to use ducting through a window for ventilation to allow the auto evaporation system to work, but this is an easy process.

As for the flaws, some users wish that the 6-ft power cord was slightly longer, but this is an easy fix with an extension cord. The other drawback is that the LP1417GSR is that there are only 2 cooling powers, which is minimal, considering the high cost of the unit and insufficient considering the high BTU rating. But all in all, this is an excellent choice if you’re looking for a portable LG for a large space, and you don’t find Smart technology a necessary addition.

5. LG LP1417SHR (Portable AC with Heating)

Specification Summary
Type of AC Portable
BTU 14,000
Cooling Area 500 sq. ft.
EER 12.0
Voltage 115V

Keeping cool in the hotter months is a necessity, but when the temperature dips in the colder months, having a dual function unit with supplemental heating is a great option. LG’s LP1417SHR portable air conditioner with heat pump technology will keep you as cool as a cucumber or snug as a bug in a rug, according to your needs. Its 14000 BTU cooling capacity is optimal for spaces up to 500 sq ft, whereas its 12000 BTU heating capacity is designed for areas up to 400 sq ft.

The auto-swing oscillating air vents circulate the warm or cool air efficiently to ensure the whole space is kept in the ‘comfort zone.’ What’s more, the dehumidification function will control the humidity in your home. With a sleek contemporary design, this free-standing portable unit blends in with almost any room décor so it will fit in where you want it when you want it.

6. LG LW1017ERSM

Specification Summary
Type of AC Window
BTU 10,000
Cooling Area 450 sq. ft.
EER 12.1
Voltage 115V

Receiving an excellent 5-star rating on from some delighted customers, this window AC unit not only meets but exceeds customers’ expectations.

This ENERGY STAR® certified unit is specially designed with energy efficiency in mind, with an impressive 12.1 EER. Its 10000 BTU cooling capacity is suitable for spaces up to 450 sq ft.  The auto restart function ensures that your AC automatically turns back on when power returns after a power outage, giving you peace of mind.

With LG’s SmartThinQ® technology, you can control your AC at home from anywhere: start or stop cooling, change the mode or set the temperature to be just how you like it when you get home. The app also works with the Google Assistant and Amazon Alexa so you can change your air conditioner settings with simple voice commands from the comfort of the sofa, without having to search for that elusive remote control.

7. LG LW8016HR (Window AC with Heating)

Specification Summary
Type of AC Window
BTU 7500 Cooling, 3860 Heating
Cooling Area 320 sq. ft.
EER 11.2
Voltage 115V

Perhaps you’re looking for a window AC unit that offers the extra dimension of a little heat when you need it in the chillier months as well as keeping your home cool and comfortable when the temperature rises. If so, look no further than this high-performing unit from LG. It offers an impressive energy efficiency Ratio (EER) of 11. 2, with 7,500 BTU cooling capacity for space up to 320 sq ft and 3850 BTU supplemental heating for up to 220 sq ft, making it ideal for smaller homes.

LG Portable Vs Window Air Conditioners Compared

One of the best features of a portable air conditioning unit is that it’s super-easy to install. These products plug into a wall socket and come complete with a window kit – effectively a pipe through which the heat removed from the air inside.

Some homeowners’ associations don’t allow the use of window AC units because they protrude to the outside. Portable units have the advantage here because the small exhaust pipe won’t violate any such rules.

The most obvious benefit is that you can move it quickly from room to room so you can enjoy its cooling effect wherever it’s needed. A window AC doesn’t offer that flexibility. If it’s not possible to vent through a window for some reason, ceiling vent kits are also available for portable ACs.

A small window unit, by contrast, removes the possible problem of the space taken up by a freestanding portable unit which is particularly relevant in homes where space is tight. Sitting in the existing window opening, without taking up any valuable floor space, window units undoubtedly reduce clutter.

Another essential factor to bear in mind in these energy-conscious times is that a window air conditioner uses energy more efficiently than a portable unit. As a result, you get more cooling power per BTU.

A top tip is to pay attention to the BTU rating when looking at window units. The higher that number is, the bigger the room the unit can cool.

Both window and portable AC units can come with many features such as digital thermostats, remotes, and timers. The presence or absence of these factors may help your decision-making process.

LG Window Vs Through-the-Wall ACs Compared

Window and through-the-wall ACs are easy to compare because they’re effectively similar in cooling capacity and size. Through-the-wall units, however, tend to be more energy efficient because they create an airtight seal in the room.

The significant differences between these types of AC units are their installation and way that they vent. Window ACs, as the name suggests, fit through a window and don’t require permanent installation. Through-the-wall ACs, on the other hand, is built into the wall. They are ideal for windowless rooms or for those who prefer not to interfere with the existing windows.

Wall air conditioners typically only vent (or exhaust) warm air through the back of the unit to the outside, while window ACs vent from both the sides and back. This is why the two types are not interchangeable, even if they are identical in size. Simply put, since a window unit needs to vent from both the back and the sides, if it’s installed in a wall, the side vents will be blocked, and it will overheat.

Comparisons with AC Brands

Haier Portable AC

A top alternative to our pick for an LG portable AC is this unit from Haier which combines compact size and performance. Its 12000 BTU cooling power will cool a room up to 450 sq ft. It includes remote control, a digital settings panel, and three cooling speeds.

Being minimalist in size and styling, it doesn’t intrude on living space unduly, and it performs well in terms of energy efficiency. It also has helpful features like auto-start and a 24-hour timer, which make it easy to ‘set and forget.’

Another feature is its self-evaporative draining system, which means you don’t have to empty the tank every day – one less thing for your to-do list. As with all portable units, it’s easy to install, with a 6ft power cord and a 5ft single exhaust hose, both of which give some flexibility on where it can be sited in your room. Read more about Haier AC units here.

In general, the Haier HPC12XCR receives good feedback, especially considering the average reviews for most portable ACs. Most users note that the cooling performance is about what they expected or better.

Koldfront Through-the-Wall AC

This through-the-wall AC from Koldfront is an excellent alternative to our LG top pick. It offers superb value for money and has both heating and cooling functions. With a 12,000-BTU rating, it can cool a space of up to 550 sq ft, and the 10,600 BTU heating element can heat an area of up to 450 sq ft.

Although it doesn’t offer the ‘smart’ control technology of our LG recommendation, it has remote control operation, an electronic digital thermostat, a sleep mode, a 24-hour timer, and an energy-saver mode. The louvers in the output vent can be adjusted to direct air in 4 directions, and there are three fan speeds plus ‘auto.’

It also has a ‘Dry’ mode for dehumidification which extracts about 2.5 pints of water from the air per hour. The lack of a self-evaporative function means that you need to empty the tank regularly, however.
