LG Electronics have proven themselves through the years to be providers of top-quality electronic appliances, across a wide range of products. Providing everything from smartphones, to refrigerators, to televisions, few corporations can boast the versatility, and continued commitment to reliability, that LG have built through the years. Today, our analyst team will be discussing one of LG’s middle-market window-mount air conditioners. The LG LW8017ERSM, unwieldy though its name may be, is an effective, and cost-cutting alternative to some of the larger more expensive window-mounted air conditioner units on the market. Both highly efficient, and convenient, this unit quietly excels in every regard, in typical LG fashion. Continue reading below for our full LG LW8017ERSM review.

LG LW8017ERSM Air Conditioner Review


Retailing for various prices, averaging out at approximately $279.99, this unit is incredibly affordable when compared to other products that we would class as middle-market units. Usually with units like the LG LW8017ERSM, most of the product’s convenient features are sacrificed, resulting the skeleton of a more advanced product. LG have chosen to retain most of the core functions of the higher end units, such as smart home compatibility, and bring them to a more affordable unit, making less sacrifice, and providing the user with more bang for their buck. Check out what we thought of the unit below.


Cooling Performance

With a moderate 8,000 BTUs of raw cooling power, the LG LW8017ERSM is suitable for installation in typical living spaces of up to 340 square feet. Further, with a maximum airflow of 220 CFM, this unit is highly capable of circulating air in its environment, all while removing up to 2.2 pints of moisture from the air per hour. This makes the LG LW8017ERSM the perfect choice for medium sized living spaces, especially if humidity is an issue.


Efficiency / Certifications

The Energy Efficiency Ratio (EER) of a product is a proven adequate measure of a unit’s performance efficiency. With the industry average EER standing at 9.7, any product that scores above 10 is considered to be highly efficient. LG have maintained a reputation for their unit’s efficient performance for quite some time now, with this particular unit scoring an EER of 12.1. In addition to this, the LG LW8017ERSM benefits from an Energy Star certification, which declares that this unit adheres to a strict set of energy consumption related regulations set out by the Environmental Protection Agency. To be Energy Star certified guarantees that the unit will function efficiently, saving you a hefty sum on your upkeep bills.

For optimum efficiency of operation, we suggest using the LG LW8017ERSM three fan speeds, using the lowest speed necessary to combat heat. This will help to save you a substantial amount of money over a long period of time.

In addition to being highly efficient, the LG LW8017ERSM is also UL-Listed. This essentially means that it’s public safety was assessed by Underwriters Laboratories, who have become somewhat of an institution of the industry over the years.



LG’s commitment to providing the buyer with a user-friendly and convenient product is evident in the LG LW8017ERSM, with the inclusion of a full-function wireless remote control, effectively allowing the user to operate their device from anywhere in the room. This is especially useful in those hot summer months where the act of having to pull yourself through the hot air to change settings on your device is the last thing you want to do.

Additionally, also included in the LG LW8017ERSM, is a 24-hour programmable timer. One of our favourite features, the programmable timer allows the user to enter a schedule of operation into their device. The unit will then power on and off according to this timetable, which is useful in the case of the user not being home to manually operate the unit. No more shall the user be forced to return home from work to a hot and humid home due to lack of air conditioning.

One aspect of this unit’s design that’s certainly worth mentioning, is that it is smart home compatible. This unit will work with Amazon Alexa, Google Assistant, Nest, and SmartThinQ.

Finally, this unit benefits from auto Restart Capability, and an Energy Saver function. Auto Restart allows the LG LW8017ERSM to automatically reboot itself following a power outage. This feature is essential for those of us who suffer frequent power blackouts due to natural disasters or infrastructural problems. Without this capability, your device will cease functioning in a power outage and will require manual rebooting to continue servicing your home. This is especially problematic if it occurs while you are away from home for a long period of time, as your air conditioning unit will not function for as long as you are away. The Energy Saver function enables the appliance to function on decreased capacities so as not to consume as much energy. This is usually achieved by the unit periodically powering off, and back on when necessary.



4-Way directional airflow allows for a more even distribution of cooling power, a slight design feature which makes a big difference, a difference that will undoubtedly be felt during the peak of the Summer.

The net weight of this unit is 58lbs, with its shipping weight coming in at approximately 65lbs. While not the heaviest of LG’s window-mounted air conditioners, the LG LW8017ERSM still boasts enough weight to make transport or installation without assistance dangerous. We strongly advise seeking help when installing this unit as a precautionary measure.

With an indoor decibel level of 54dB, the LG LW8017ERSM is relatively quiet. For reference, the average human conversation usually registers at approximately 60dB, so this unit will not likely disrupt you as you go about your daily business at home. That being said, whether or not this unit is suitable for installation in a bedroom or other rooms that require low-noise, is entirely up to the user depending on their noise tolerance.

As is largely industry-standard nowadays, the LG LW8017ERSM contains a washable filter, which is accessible through a top down chassis. To aid with keeping this filter clean, there is a built-in filter alarm function, to notify when the filter is blocked. We strongly advise cleaning the filter as often as the instructions manual suggests, as the efficient performance of the device will suffer immensely if the filter is blocked.


Help & Support

As an LG product, owners of the LG LW8017ERSM benefit from LG’s wide-range of customer service resources available online, which include FAQs, Troubleshooter, Service scheduling information, Tutorial videos, downloadable user manuals, and more. If you encounter an issue with your unit, and none of these resources provide an effective solution, we recommend contacting an LG representative via telephone, email, social media, or online  live chat.

This product is also backed by LG’s 1-year parts and labour limited warranty. For more information regarding LG warranty terms and conditions, we recommend contacting the company directly prior to purchase.



All factors taken into consideration, the LG LW8017ERSM is a fantastic choice of air conditioner from the middle-market. Capable of providing all the necessary core-functions of what would be considered a high-end unit, this affordable alternative is effective at getting the job done, with little to no hassle. With a simple and easy-to-understand design, this is a unit you will be able to operate instantly. We especially found the smart home capabilities of this device to be a nice touch. If we were to pick issue with this device, it would be the lack of some of the convenient features we have become accustomed to in the more expensive units on the market. However, such oversights can be forgiven when considering the price of the unit, and the number of features that are included.
