LG Ductless A/C Systems

LG duct-free cooling and heating systems for a single-zone application are among those with the highest rated performance and efficiencies in the market today. LG single-zone units comprise of four types of systems with varying styles, designs, and capacities. These solutions include the following:

The stylish, highly-efficient, and powerful high-wall, duct-free Art Cool™ systems that consist of Art Cool™ Gallery, Art Cool™ Premier, and Art Cool™ Mirror. Advanced and innovative, these cooling/heating systems are available a range of finishes that include a customizable picture area that enables you to place an artwork or photo. Powered by variable speed compressor, these units practically change the way indoor units are designed—aesthetic-wise. In terms of capacity and efficiency, LG Art Cool™ models are available up to 24,000 Btu/h and have efficiency ratings of up to 28 SEER.
The elegant but highly economical Mega Inverter high wall duct-free units that are available up to 24,000 BTU/h and with efficiency ratings of up to 17.0 SEER. These models also use the powerful inverter technology and come in different stylish designs.
The light commercial systems that include the ceiling cassette and high static ducted models. These units have rated capacities of up to 42,000 BTU/h and have efficiency ratings of up to 20 SEER.
The ultra-powerful and highly efficient LG single-zone wall-mounted models that are available with up to 22,000 Btu/h rated cooling capacity and a 27,600 Btu/h rated heating capacity. These units also have efficiency ratings of up to 21.5 SEER.

This article will particularly focus its discussion about the LG single-zone wall-mounted models. Take note that these systems are available up to four (4) models, but in this particular review, we will just be specifically looking at the three models which are currently available at ComfortUp, namely:

LG LS090HSV4
LG LS120HSV4
LG LS180HSV4
More options to be added soon

What are the LG Single-zone Wall-mounted Air Conditioners and Heat Pump?

LG LS090HSV4 The LG LS090HSV4 replaces LG LS091HSV3. An inverter-driven system, this model has a rated cooling capacity of 9,000 Btu/h and a rated heating capacity of 10,800 Btu/h. Given these capacities, this might work as your best option if your room size ranges from 300 square-feet up to 500 square-feet. Designed with industry-standard efficiencies, this model brings in a 21.5 SEER, 13.3 EER, and 10.8 HSPF. LG LSU120HSV4 The LG LSU120HSV4 model replaces LG LS121HSV3. Also an inverter-driven system, this unit has a rated cooling capacity of 11,200 Btu/h and a rated heating capacity of 13,300 Btu/h. This system is perfect if your room has a size of 400 square-feet up to 650 square-feet. In terms of efficiencies, this particular model boasts of a 21.5 SEER, 12.5 EER, and 11 HSPF. LG LS180HSV4 Like the other models in the series, this unit is also a new system and replaces LG LS181HSV3. Built with the powerful inverter technology, it has a rated cooling capacity of 18,200 Btu/h and a rated heating capacity of 22,000 Btu/h. In terms of application, this particular model is ideal to be installed in rooms with a size that is not smaller than 600 square-feet and not bigger than 1000 square-feet. Also a high-efficiency system, this models is available with 20.5 SEER, 12.6 EER, and 9.7 HSPF.

System Comparison

Now, let’s try to compare these systems by looking at their cooling and heating capacities, operating ranges, sound pressure levels, and other pertinent data.

Capacity: In terms of cooling and heating capacities, it would be understandable that the model designed for a bigger space would have higher capacities than the model that is built for smaller rooms. This means that the model LS180HSV4 would have the bigger capacity ranges in terms of cooling and heating compared with the other two. The model LS090HSV4, it turns out, would have the lowest capacity ranges among the three units. Check out the table below for the specific capacity data about these models.
Energy-efficiency: While the model LS180HSV4 comes with the biggest capacities, it is starkly obvious that it has much lower Seasonal Energy Efficiency Rating (SEER) compared with the other two units with lower heating and cooling capacities. Specifically, LS180HSV4 has a SEER of 20.5, which is a bit lower than the 21.5 SEER that you would get from models LS090HSV4 and LS120HSV4. The Energy Efficiency Rating (EER) of LS090HSV4, however, is the highest among the three, which comes at 13.3. Coming in second is LS180HSV4 with 12.6, while the lowest is LS120HSV4 with 12.5. With regard to the Heating Seasonal Performance Factor (HSPF), the model LS120HSV4 has the highest with its 11 HSPF. Model LS090HSV4 follows with its 10.8 HSPF. While the model LS180HSV4 has 9.7 HSPF, which comes as the lowest among the three.Operating Range When it comes to operating ranges, all of the three models are similar. Check out the table below for the details.
Sound Pressure: Sometimes, how quiet the unit operates makes all the difference in terms of achieving immediate comfort. With these particular LG models, the models LS090HSV4 and LS120HSV4 are the quietest while in operation mode. They can operate with a noise down to 19 dB(A) for the indoor unit and a maximum of 45 dB(A) for the outdoor unit. In contrast, the model LS180HSV4 can operate with noise down to 29 dB(A) for the indoor unit and a maximum of 53 for the outdoor unit. Check out the table below for the complete details.
Piping System: With regard to the piping system, the models LS090HSV4 and LS120HSV4 require a liquid line with a size of 1/4 inches and a size 3/8 inches for the suction line. For the model LS180HSV4, you will need a liquid line with a size of 3/8 inches and a suction line with a size of 5/8 inches. You can refer to the table below for the additional size considerations on the piping system for these particular models.Additionally, all of the three models are built with the ozone-friendly refrigerant R410A, designed with a 4-way remote air flow control, and come with a washable air filter. Except for the model LS180HSV4 that uses a twin rotary compressor, the other two models are built with a rotary compressor system. All the models also come with the same type of remote controller (AKB73835317).

Warranty and Other Additional Information/Specifications

As outlined, buying these models gives you a 7-year warranty on the compressor system and a 5-year warranty on parts as long as you can show proof that you are the original registered end-user and be able to provide proof of proper installation. You can check the table below for additional reference.
