10 best LG air conditioners in 2026 (10+ compared)

Are LG air conditioners good?

Buying Criterion

LG air conditioners have an average overall score of 7.7, ranking #4 among comparable air-conditioner brands.

LG air conditioners are a strong choice for connected homes that value app control, distinctive airflow, and a broad value-to-premium range. Entry models cover straightforward cooling and heating, while DualCool, Libero, and Artcool families add more refined airflow, indoor design, or air-quality functions.

LG air conditioners suit buyers who will use ThinQ control, dual airflow, or a design-led indoor unit, but the exact model decides the sound level, filters, heating output, and included Wi-Fi. The main limitations are feature variation between generations and the need to verify local service, app support, and installation combinations.

The chart below compares LG with other air-conditioner brands by average overall score.

What are the main advantages of LG air conditioners?

The main advantages of LG air conditioners are as follows:

Connected control: ThinQ-compatible systems can provide app control, schedules, monitoring, and selected smart-home routines. Confirm the exact Wi-Fi module, account, network, and offline remote behaviour.
Airflow comfort: DualCool and related systems can shape or separate airflow to reduce direct draughts in suitable rooms. The benefit depends on the mode, louvre position, room layout, and model generation.
Broad range: LG covers value wall units, practical Libero or DualCool families, and design-led Artcool-style systems in supported markets. This gives more choice but makes exact model comparison essential.
Heating and efficiency: Inverter control, SEER, and SCOP can support efficient cooling and useful heating. Compare low-temperature output if the system will heat regularly rather than only in spring.
Indoor design: Design-led LG units can fit a prominent living-room wall better than a basic cabinet. Measure depth, clearances, filter access, and airflow before paying for appearance.

What are the main disadvantages of LG air conditioners?

The main disadvantages of LG air conditioners are as follows:

Model variation: ThinQ, DualCool, filtration, sound modes, and heating functions vary across generations and markets. Read the complete model code and energy label instead of relying on the family name.
Smart-home dependence: App features need a supported account, network, and platform. Local remote control should remain available, but cloud routines and monitoring may stop during an outage.
Design premium: Artcool and better-equipped indoor units can cost more without changing the room's required capacity. Pay for the finish or airflow function only when it has a clear everyday benefit.
Installation limits: Multi-split systems need approved combinations, simultaneous capacity, drainage, electrical work, and careful commissioning. A smart or premium indoor unit cannot hide an unsuitable outdoor installation.
Support and parts: App support, filters, remotes, and warranty handling can differ by generation and retailer. Confirm local service and replacement-part channels before choosing an uncommon model.

What are the main LG air conditioner series?

Buying Criterion

The main LG air conditioner families are as follows:

Entry wall-mounted models: LG's entry wall-mounted models focus on conventional cooling and heating at a more accessible price. They suit buyers who do not need DualCool airflow or a design-led cabinet, subject to checking the current efficiency and control specification.
Libero: Libero families provide a practical step up with inverter comfort, connected features, and common room capacities in supported markets. Verify the exact suffix for ThinQ, filtration, sound, and heating details.
DualCool: DualCool systems emphasise separate or shaped airflow and connected comfort functions on selected models. They fit rooms where direct draughts are a concern, but mode behaviour and capacity still need model-level checking.
Artcool: Artcool is the design-led family for buyers who want the indoor unit to suit a visible wall. Its finish can improve the room's appearance, but it may add cost and require careful clearance and cleaning planning.
LG multi-split: Compatible LG outdoor units can serve several indoor spaces with approved combinations. Confirm simultaneous output, pipe limits, independent controls, drainage, and local service before selecting a multi-room layout.

How much do LG air conditioners cost?

Price Guide

LG air conditioners cost about £300-£1,100 for equipment, with professional installation priced separately. Entry wall units are often around £300-£500, while Libero, DualCool, connected, or better-equipped models commonly sit around £500-£900.

Artcool, larger capacity, premium heating, and multi-split combinations can reach roughly £900-£1,100 or more before installation. Add brackets, pipework, electrical work, drainage, commissioning, and any optional Wi-Fi or control hardware.

How do LG air conditioners compare with Samsung models?

Buying Criterion

LG and Samsung both offer connected inverter air conditioners with value, premium, and design-led families. LG emphasises ThinQ control, DualCool airflow, and Artcool styling, while Samsung stands out for WindFree dispersed airflow and SmartThings integration on selected models.

LG entry, Libero, DualCool, and Artcool families provide a broad step-up path. Samsung AR35 and WindFree ranges offer a similar spread, with exact quiet modes, filters, heating behaviour, and app functions changing by model and generation.

Choose LG when its airflow, ThinQ platform, indoor design, local support, or price fits the room. Choose Samsung when WindFree comfort or SmartThings matters more; compare the exact installed model's efficiency, sound, heating, and included connectivity rather than the brand feature list.

What should you consider while choosing the best LG air conditioner?

Key Factors

Before choosing an LG air conditioner, consider the following factors:

Capacity and heat load: Match capacity to room area, insulation, glazing, ceiling height, solar gain, and occupancy. A 2.5–3.5 kW class often suits ordinary rooms, but the actual heat load should decide the model.
Entry, Libero, DualCool, or Artcool: Choose the family by the function that matters: value, connected comfort, airflow control, or indoor design. Confirm the current suffix because ThinQ, filters, sound, and heating can differ.
Airflow and sound: Check louvre control, low-mode and maximum indoor sound, and whether DualCool or a similar mode changes the airflow path. Direct draught avoidance must still leave enough airflow for the room.
SEER and SCOP: Compare seasonal cooling and heating ratings at the same capacity and climate assumption. SCOP and low-temperature output matter when the unit will provide regular heat.
ThinQ and offline control: Confirm app compatibility, Wi-Fi inclusion, account requirements, firmware support, and local remote behaviour. Smart features should remain optional to basic cooling and heating.
Filters and maintenance: Check the exact filter type, cleaning interval, replacement cost, and access around the indoor unit. Design fronts and air-treatment features can change maintenance effort.
Installation and service: Confirm approved indoor/outdoor combinations, pipework, drainage, commissioning, warranty, local service, and spare remotes. A premium indoor unit is only as reliable as the installed system.
