LG Air Conditioner Buyer’s Guide – HVAC Brand Review

| Last Updated: April 26, 2022

There are many different types of air conditioning systems from central air conditioning systems that cool the entire home to window or portable air conditioner systems that cool just one room or space.  There are even systems that can cool several rooms at once (multi-zone) that are not considered central air conditioning systems.

Regardless of the size of the space you are trying to cool in your home, an air conditioning system is an investment for most homeowners, so you want to carefully evaluate air conditioning systems and get the best bang for your buck.

No one manufacturer produces all types of air conditioning systems. Additionally, not all air conditioning brands are alike. When trying to evaluate an air conditioning system to cool a single garage or bonus room, or a few rooms in your home or condo, you want to look at the energy efficiency, quality of manufacturing, reliability, ease of use and maintenance, warranty, and the price. The LG brand is one of the better-known manufacturers of smaller air conditioner units.

How Does LG Compare to the Competition?

We all use LG appliances in our daily lives. They are known for their reliability, durability, and top quality. The question that arises here is that amidst the presence of some well-known brands on the market, what makes LG stand out from its competitors? In this section, we have gathered a couple of features that help LG in marking its position in the electronic world.

Smart Features

LG is ideally known for adding comfort in our daily lives. LG products are incorporated with some advanced features that not only make them user-friendly but also enhances the performance of the appliance. For example, most of the LG air conditioners are equipped with an LED display or a display panel that eases the task to a great extent.

Remote Control Functionality

Another feature that makes these air conditioners immensely popular in the electronic crowd is that you can operate it by merely sitting on the sofa with the help of a remote control. You don’t have to get up and adjust the settings when you have an LG air conditioner installed in your house.

When looking at smaller air conditioning units, your are more likely to be looking at EER values of energy efficiency rather than SEER values, so it is important to understand the difference between the two.

SEER stands for Seasonal Energy Efficiency Rating and is a measure of the cooling power of the air conditioner over a typical cooling season. It is an average of the highs and lows in a typical home’s cooling energy usage. THE SEER rating is commonly used when looking at a large, central air conditioning unit. A SEER value can range between 8 to 30, but very few AC systems have a SEER rating above 23.

EER stands for Energy Efficiency Rating and is an older method of calculating energy efficiency in an air conditioner. However, it is more of a constant, accurate measure because it is a measure of the cooling energy usage at a specific peak cooling time. Seasonal temperature changes are not factored into the calculation of an AC unit’s EER rating. The EER rating is more commonly used when looking at smaller window, through-the-wall, mini-split, or portable air conditioning units. An EER rating can range between 6 and 16.

It is important to note that both the SEER and the EER can be Energy Star qualified, however, the US Government only mandates that the SEER be displayed on air conditioners.

The U.S Department of Energy’s rule in AC energy efficiency divides the country into 3 regions with the following energy requirements:

Northern region: SEER rating of no less than 13

Southern region: SEER rating of no less than 14

Southwest region: SEER rating of no less than 14 and an EER of no less than 11.

The Best of LG

Unlike many of the major brands, LG does not manufacture central air conditioning systems. Instead they concentrate on manufacturing small window and through-the-wall air conditioning units, portable air conditioning units, and ductless air conditioning units, used to cool from one to 8 spaces.

Overall LG’s air conditioning units are considered to be reasonably priced, efficient, and reliable.

LG has developed several proprietary technologies.

Variable Refrigerant Flow Technology

The company’s variable refrigerant flow (VRF) technology reduces energy-efficiency losses and produces energy savings.

Gold Fin Anti-Corrosion

LG’s Gold Fin is an anti-corrosive epoxy treatment that prevents corrosion on the coil of the outdoor heat exchanger in order to maintain excellent heat transfer properties in the coil for an extended period of time.

LG’s Dual Inverter Compressor

The dual inverter compressor in many LG units constantly adjusts the compressor’s speed to maintain the desired temperature. It has a wider rotational frequency so it cools faster, air is expelled farther, and the unit runs quieter and saves more energy than conventional compressors.

LG SmartThinQ® Technology

This connected technology lets you control your LG air conditioner from anywhere so you can start or stop cooling, change the mode, or set the temperature from your phone, office computer, or wherever you may be.

It also works with the Google Assistant and Amazon Alexa so you can change your air conditioner settings with simple voice commands when you’re at home.

The Drawbacks

No brand is perfect. Let’s have a look now at some of the negatives about LG’s AC products.

LG Only Offers Limited Warranties

LG offers a 1-year limited warranty on parts and labor for its older ducted portable, window and wall air conditioner units.

LG offers a 5-year limited warranty on parts for Multi F/ Multi Max Multi Zone indoor and outdoor Units and specified models. On such units and additional 2-year compressor parts warranty is also offered.

Warranties are limited to replacement or repair of parts. LG will not replace the entire unit if faulty.

Consumer Reviews of LG Were Unfavorable

ConsumerAffairs.com gave LG Air conditioners a 1 ½ star rating out of 5 based on 97 consumer reviews. They noted that LG air conditioner models manufactured since 2012 have not lasted as long as older model LG air conditioners. Some consumers reported that after 2 to 4 years, the units quit working due to problems with the control panel circuit board or the compressor.

As with many manufacturers, certain models may not perform as well as other models. Generally, when consumers post reviews, it is not unusual to find that more negative than positive reviews are posted since many people do not take the time to post a comment about a product they are satisfied with.

In light of this, it is worth noting that in 2017, Consumer Reports listed the LG brand in the top 3 for window air conditioners. Additionally, two other review sites, consumersearch.com and yourbestdigs.com afforded LG the top brand for portable air conditioners.


Other LG AC Units

Here are some other LG AC units explained:

LG Single Zone Cooling Units

PORTABLE AC: LG manufactures 24 models of portable air conditioning units ranging from 7,000 BTU to 14,000 BTU. They can cool spaces ranging from 200 sq.ft. to 500 sq.ft.

EER ratings range from 8.5 to 10.1. Most units feature LED display panels, thermostat control, remote control, 24 hr on/off programmable timers, 2 fan speeds, rotary compressor, and front air discharge.

Window AC

LG manufactures 60 models of window air conditioner units ranging from 6,000 BTU to 24,500 BTU. That allows for cooling spaces ranging from 260 sq.ft. to 1560 sq.ft.

EER ratings range from 9.4 to 11.5. Most models feature 2-way or 4-way air deflection, multiple fan speeds, adjustable thermostats or thermistors, 12-24-hour on/off timers, rotary compressors, and top discharge. Most utilize R410A refrigerant.

Through-the-Wall AC

LG manufactures 41 models of wall-mounted single-zone air conditioning systems ranging from 8,000 BTU to 36,500 BTU. The EER ratings range from 9.6 to 12.1.

Most models feature 2-way or 4-way air deflection, adjustable thermostats or thermistors, 12-24-hour on/off timers, rotary compressors, and top discharge. Most utilize R410A refrigerant.

Duct-Free Single-Zone Systems

LG Art Cool™ Premier wall-mounted cooling systems are duct-free split single-zone systems designed to cool any room. They are available in models ranging from 9,000 BTUs to 24,000 BTUs. These units feature a 24-hour on/off timer and low ambient temperature operation down to 14F. They have a self-cleaning indoor coil, an ultra quiet fan and motor, and outdoor compressor. Three temperature and fan speeds set automatically.  

Units can be upgraded with LG trademark Art Cool Mirror Inverter Technology, which uses a variable speed compressor that automatically reverts to low speed when the selected temperature is reached. This helps provide energy savings and consistent comfort levels. Such technology allows efficiency ratings of up to 20.5 SEER.

Units are available in mirrored finishes or are customizable with the LG Art Cool™ frame which allows the user to display their favorite photo in a customizable frame.  

Duct Free Multi-Zone Systems

LG manufactures multi-zone systems ranging from 18,000 BTU/h to 60,000 BTU/h.

The Multi F Series are outdoor air conditioning units with heat pumps that can support two to four indoor AC units with little to no ductwork required. They can range from 18,000 to 36,000 BTU.  Multi F Series units include inverter variable-speed compressors on the outdoor units. They also have self-diagnosis capability, auto operation and restart, and LGRED heat technology to operate even in extreme cold.

The Multi F Max Series are outdoor air conditioning units with heat pumps that can support 8 indoor AC units and range from 48,000 to 60,000 BTU. The Multi F Max Series offers the same features as the Multi F Series.

Finding The Best Prices

Getting the best price on your air conditioning system starts with doing some research on efficiency, reliability, and features offered, for the major brands you are interested in. If you have some information under your belt, it will make it easier to talk to HVAC contractors about what you are looking for in an air conditioning system. Here are a few other ways to get the best prices.

Correctly Determine the Size of the System You Need

Many people don’t really know how to determine what size air conditioning system they need for their home. You don’t want to get a system that is too big for your needs because, it will cool the home faster than it can remove the humidity. This results in a cold, damp air quality that would be uncomfortable.

The calculations can be complex so working with a reputable HVAC contractor is key to getting the proper size system for your home. While there’s a little more leeway with portable or window units when dealing with a single room, you should still have a professional consultation if you’re going for a multi-zone system.

Time of Year

Many people might think that the best time to buy an air conditioner would be in the winter. If you’re dealing with portable, window or through-the-wall units, you might want to start looking toward the end of summer, although, when retailers are staging for the next season. For more complex systems that require professional installation, fall and winter are the ideal times.

Don’t Rule Out Tax Breaks

The government offers tax credits to homeowners to encourage them to purchase energy-efficient appliances because that helps reduce the consumption of energy on a national basis. This generally applies to central air or heating systems. But some ductless systems may qualify.

What Kind of Warranty Does LG Offer?

Photo credit: lg.com

An impressive warranty on a product surely enhances the confidence of customers in it. Like other popular brands, LG offers a certain warranty on its products to ensure a reliable purchase. With the purchase of LG products, you get to enjoy a great warranty on different parts. Moreover, the striking news is that LG has extended its labor warranty as well.

The new cooling system comes with a 5-year warranty on the compressor. Plus, it also covers the 5-year labor expenses to save you from additional expenditures. Similarly, the linear or inverter compressor is backed by a 10-year warranty that covers the damaged parts. Moreover, the labor warranty lasts for 5 years, which is very impressive.

Talking about the other non-cooling parts of the system, LG offers a reliable warranty of 1 year for damaged parts and a similar warranty as well, to cover the labor expenses. Overall, the general warranty for most of the LG products, including air conditioners, usually lasts for 2 years, which takes care of all the damaged parts.

These warranties work in case of faulty quality, poor performance, or function in everyday use of the product. All these warranties begin from the date of purchase, and you.
