The Best LG Air Conditioner: Our Choices
Buying criteria: You can use these factors to compare and evaluate LG air conditioners
We give you an overview of the relevant criteria that you can use to decide between the different LG air conditioners. The following factors will help you compare the different models:
Now you can find out what the individual criteria are.
Design and construction
LG does not manufacture mobile air conditioners, but only split air conditioners. These consist of an indoor and an outdoor unit.
Outdoor units usually look quite similar. For the indoor unit, different designs are suitable depending on the structural requirements of the premises. A ceiling cassette is suitable for a suspended ceiling into which it is inconspicuously installed. It is usually placed in the centre of the room.
If you do not have a suspended ceiling or have a high ceiling, an under-ceiling unit or, in the case of LG, a "ceiling unit" is suitable. The strong air flow reaches every corner - up to a ceiling height of 4.2 metres. If you need a strong cooling capacity and do not mind draughts, such a unit is suitable.
If the air conditioner is to be completely invisible, a recessed ceiling unit - at LG "duct unit" - is ideal. The compact unit is installed completely in the ceiling or in an adjacent room.
If you need powerful performance in a very small space, a floor-standing unit is suitable. It fits into any corner and can be installed quickly.
|Ceiling cassette||Suitable for suspended ceilings, inconspicuous, connection lines invisible in the ceiling, good air distribution|
|Under-ceiling unit||No suspended ceiling required, inexpensive, quick installation, easy maintenance, strong air flow even for high ceilings|
|Ducted unit||Invisibly installed in the ceiling, various air distribution systems can be used, uncomplicated installation and maintenance|
|Floor-standing unit||powerful performance in a very small area, no suspended ceiling necessary, quick installation, low-priced|
|Wall-mounted unit||draught-free air, very quiet, can cool and heat|
|Chest unit||low-priced, compact size, quick installation|
With a wall-mounted unit, you have draught-free air because the air escapes upwards. The unit is mounted on the wall like a radiator. Due to its special design and compact size, a chest unit can easily function as a floor chest, wall unit or ceiling unit. This is why it is also called a flexible unit.
The dimensions of air conditioners vary greatly for both indoor and outdoor units.
If you want a chic design for the indoor unit of your air conditioner, you should take a look at the wall unit "Artcool Gallery". With a picture frame, it looks like a wall painting. You can change the picture at any time.
This is one advantage of split units over monobloc units: The noisier part of the air conditioner is outside. Often, however, the indoor units do not work completely quietly either. LG advertises that its indoor units are up to 50% quieter than comparable models due to special screw fans and a quiet BLDC motor technology.
The indoor units sometimes only reach a quiet 19 dB and the outdoor unit about 49 dB. The units also have a whisper mode that reduces the noise level by 3 to 6 dB, depending on the model.
But it depends on the noise level at the next property: If the nearest building is at such a distance that the noise level arrives there sufficiently reduced, the unit is permissible.
An air conditioner with a low cooling capacity needs more time and energy to cool the room.
Two units of measurement indicate the cooling capacity: BTU ("British Thermal Unit") and Watt. For air conditioners, BTU/h indicates the maximum cooling capacity per hour. The unit watt also expresses the amount of energy used in a given time: 1,000 BTU/h correspond to about 293 watts.
According to an EU regulation, from 2025 air conditioning systems may only contain refrigerants with a global warming potential of 750 or less. Until now, LG had used the usual refrigerant R410A with a global warming potential of 2088.
This is now no longer possible in split units with a charge of up to 3 kg. In the meantime, LG has switched most of its units to the more environmentally friendly refrigerant R32 (difluoromethane), which complies with the condition. R32 is considered a highly efficient refrigerant that ensures lower energy consumption. As it is more efficient than the previously used R410A, it can be used in much smaller quantities. The refrigerant R32 is 68% less harmful to the environment than the commonly used R410A and is easily recyclable.
Since you should never come into contact with the refrigerant, only professionals should install your air conditioner. There are certified companies for this purpose.
The SEER value is decisive for the energy efficiency of your air conditioner. This is more informative for an air conditioner than the classic energy efficiency classes from A+++ to G.
The SEER stands for "Seasonal Energy Efficiency Ratio" and indicates the ratio of cooling capacity to energy consumption.
In other words, it tells you how much electricity the air conditioner needs for its cooling capacity. In contrast to the EER value, the SEER value takes into account the respective climate. Since 2014, the EU has stipulated that split units must have a SEER value of at least 4.6. Units with a low climate-damaging refrigerant only need a value of 4.14.
Energy-efficient split air conditioners achieve a SEER value higher than 8. LG's units have SEER values of 6.6 to 8.5. In addition, an inverter air conditioner is more energy efficient than an on/off unit due to its flexible rotation speed.
Guide: Questions you should ask yourself before buying an LG air conditioner
What differentiates LG air conditioners from other manufacturers?
LG air conditioners are quick and easy to install. The automatic cleaning function of the wall-mounted units prevents the formation of mould and bacteria and ensures healthy air and a long service life for the unit. In addition, LG air conditioners filter dust, pollen and cigarette smoke from the air. The air conditioners also reduce high humidity. Some of the wall units also have a heat pump function that keeps the home warm.
LG does not manufacture mobile air conditioners (monobloc units), but only split units. These consist of two parts: an indoor unit that is installed in the room and a compressor that is attached to the outside wall of the building. In addition to single-split units, LG also offers multi-split units. With these, you can connect up to ten indoor units to one central outdoor unit.
Does an inverter air conditioner make sense?
The advantage: Inverting air conditioners consume less electricity and operate more quietly. At the same time, they reach the desired temperature much faster than on/off air conditioners. You usually pay a little more for an inverting air conditioner, but the advantages outweigh the disadvantages.
In what price range can I get an LG air conditioner?
You can buy the indoor unit and the outdoor unit either separately or together as a set. The outdoor unit costs more than the indoor unit. A single-split outdoor unit starts at 600 €, while a multi-split outdoor unit costs 800 € to over 5,000 €. Indoor units are available from €340, with units costing up to over €5,000.
What are the alternatives to an LG air conditioner?
If your landlord does not allow this or if you only need the air conditioner occasionally, a mobile air conditioner is a good option. A mobile air conditioner ("monobloc unit") costs less to buy but has higher electricity costs.
If it is only used occasionally, it is worthwhile. Mobile air conditioners are also available from electrical retailers. Manufacturers such as De'Longhi, Trotec, Argo, Wiland or Klarstein offer efficient air conditioners. If you are looking for another manufacturer of split air conditioners, Samsung, Midea, Mitsubishi, Daikin or Heiko offer a selection.
How do I disinfect the LG air conditioner?
You can remove removable parts such as the grille and air filter with a screwdriver and clean them separately. Cleaning the air filter is particularly important. It can quickly become clogged, which weakens the cooling performance of the unit. You should clean it once a month. You can find special disinfectant sprays for cleaning air conditioners in shops and on the Internet. These disinfect both the evaporator and the ventilation system of the air conditioner. You should also clean the outside unit of the split air conditioner, as it sucks in particles such as pollen. Wipe the dirt from the inside to the outside.
How often you should clean the air conditioner depends on various factors such as the model and the intensity of use. Some experts recommend cleaning the air conditioner once a year. However, if you notice a musty smell in the room, it might be time for a cleaning.
Why does my LG air conditioner make unusual noises?
|Occurrence and type of noise||Cause|
|Noises when switching off||Since each component repositions itself as originally when switched off, noises are common here. Noises are also normal when first used.|
|Humming noises from the indoor unit||Clogged or blocked filter. There may be a leak, causing condensation on the vane.|
|Humming noises from the outdoor unit||Clogged air filter. Blocked air inlet and outlet due to objects. Motor may vibrate if outdoor unit is placed unevenly.|
Basically, it can help to clean your filter regularly. If there are obstacles in the vicinity of the air conditioner, you should remove them. If the outdoor unit makes noise, check that it is level and stable. If not, adjust the position if possible.
If the unit is mounted on a roller shutter or on a cabinet, you can place damping rubber pads under the outdoor unit or fix vibrating parts with cable ties.
