The LG DUALCOOL AI AIR Deluxe Pro 12,000 BTU is a high-efficiency, AI smart learning wall-mounted split system designed to provide year-round climate control. It is particularly popular for its balance of energy efficiency, quiet operation, and smart integration.
The details
AI-Powered Intelligence
- Smart Learning: The system tracks your daily routines and temperature preferences, automatically adapting its operation to provide personalized comfort without manual input.
- AI Airflow Optimization: Using real-time room sensing, the AI fine-tunes fan speed and airflow direction based on occupancy and ambient conditions.
- Active Energy Management: Intelligent operation reduces unnecessary consumption, while Active Energy Control lets you cap power usage at 80%, 60%, or 40%.
Advanced Air Quality
- Total Purification: Combines Ion Technology to neutralize odors/bacteria and Microparticle Filtration to trap ultra-fine dust.
- Self-Cleaning: An automated internal drying cycle prevents mold and bacteria buildup, ensuring the air stays fresh.
Performance & Reliability
- DUAL Inverter Compressor: Delivers rapid, powerful cooling and heating even in extreme weather conditions.
- Gold Fin™ Protection: A specialized anti-corrosion coating on the heat exchanger ensures long-term durability.
- Ultra-Quiet (19dB): Refined airflow design allows for near-silent operation, ideal for sleep or work.
Connectivity & Eco-Efficiency
- LG ThinQ App: Full Wi-Fi control to manage settings, schedules, and energy monitoring from anywhere.
- Eco-Friendly R32: Utilizes high-efficiency refrigerant that is better for the planet and your electricity bill.
- A+++ Energy Rated: Optimized for high output with low power input (as low as 0.89 kW).

Tech stuff
The unit must be installed by a F-Gas qualified AC engineer. Please ensure the qualified fitter reads the user manual in full before installing.
These units contain a gas which is governed by F-Gas regulations. The gas must be handled by a qualified F-Gas personnel. Further information on the requirements and ensuring the engineer is qualified can be found at: Government Guidance
* Note: In order to reduce the Global Warming Potential, the outdoor unit footprint and provide extra energy savings; our outdoor units have a rating lower than the sum of indoor units BTU. Please note this will not affect the cooling or heating in individual rooms as those units are variable cooling inverters and they balance the cooling or heating power among the indoor units to achieve the target temperature in the shortest time. Please make sure you size the units as per our room guidance or call for tech support.
Question from .: Asked on 27/05/2026 What size is the outdoor unit and what surrounding clearance is required
Hi, The outdoor unit measures approximately 717 × 495 × 230 mm (W × H × D). Installation requires sufficient clearance around the unit to ensure proper airflow and servicing access. As a general guide from LG installation practice, allow space around all sides of the unit, with additional clearance at the front for airflow discharge and at least 300 mm above. Exact spacing should always follow the installation manual and installer assessment based on the site conditions.
Thank you.
Question from Bernie: Asked on 25/05/2026 Can I fit myself.
Hi Bernie,You can do some basic preparation work like mounting the indoor unit and drilling the wall hole, but you cannot legally or practically fully install the LG split air conditioner yourself in the UK because the refrigerant connection and commissioning must be carried out by an F-Gas certified engineer.Thanks!
