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.
SEER vs. EER
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 to 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 not less than 13
Southern region: SEER rating of not less than 14
Southwest region: SEER rating of not less than 14 and an EER of not 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-CorrosionTM
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 CompresserTM
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.
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 models1. On such units and additional 2-year compressor part 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.
LG’s Top Models

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, though, 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.

An air conditioner’s performance depends not only on the quality of its installation and how well it is maintained but also on the equipment itself. LG’s brands are known among HVAC professionals as one of the larger names in small home cooling, heating and energy-efficient systems.
With over 35 years of operating history in the US, LG has a significant presence in the small unit HVAC market. While some of LG’s brands have received some poor ratings and reviews, it is difficult to know whether that is due to the actual equipment itself or installation quality.
Generally, most component failures can be traced back to improper installation. Overall, an LG unit can be expected to deliver reliable and efficient performance at a reasonable price.
