All-Season Comfort & Superior Energy Efficiency: Your Year-Round Climate Partner
The Lloyd Stellar Duo is designed to be your primary climate control appliance for every season.
Hot & Cold Operation (-4°C to 52°C): True All-Weather Versatility
This is the defining and most significant feature of the Stellar Duo. It offers true all-weather comfort, capable of efficiently cooling during scorching summers (up to 52°C) and providing powerful heating during chilly winters (down to -4°C). Direct Benefit: This eliminates the need for separate heating appliances, providing a single, integrated solution for year-round climate control, making it highly suitable for regions with diverse climates.
Superior 5 Star Energy Rating (ISEER 5.20): Maximizing Savings Across Seasons
With a 5 Star Energy Rating and an ISEER of 5.20, the Stellar Duo demonstrates excellent energy efficiency in both cooling and heating modes. While slightly lower than some cooling-only models, this is a top-tier rating for a hot & cold inverter AC. Economic Advantage: Its low annual electricity consumption (751.96 kWh) translates to substantial savings on your power bills throughout the entire year, a crucial factor for long-term ownership in India.
1.5 Ton Cooling & Heating Capacity (5050W): Powerful Dual Functionality
This AC provides powerful and efficient cooling in summers and robust heating in winters, with a capacity of 5050W for both functions. It effectively covers an area of 15.8 m² (approximately 170 sq. ft.) ensuring rapid and consistent comfort, irrespective of the season.
Comprehensive Air Quality & Advanced Smart Features: A Healthier, Smarter Home
Beyond temperature control, the Stellar Duo prioritizes the air you breathe and intelligent interaction.
In-Built Air Purifier: Year-Round Health Guardian
The inclusion of an In-Built Air Purifier significantly enhances indoor air quality. It actively removes pollutants, allergens, dust, and harmful particles from the air. Health Benefit: This contributes to a healthier living environment year-round, especially beneficial for individuals with allergies or respiratory sensitivities.
High CO2 Alert: Crucial Safety and Air Quality Monitoring
A highly important health and safety feature, the High CO2 Alert monitors carbon dioxide levels in the room. If levels become too high, it provides an alert, prompting you to ventilate the space for better indoor air quality. This is particularly important in sealed environments during winter heating.
Door Open Alert: Preventing Energy Waste
This smart safety and efficiency feature alerts you if a door or window is left open while the AC is operating. Energy Saving: This helps prevent energy waste by prompting you to close openings, ensuring the AC runs optimally and efficiently.
In-Built Wi-Fi (Voice & Wi-Fi Enabled) & Direct Voice Command (“Hello Lloyd”): Ultimate Convenience

The revolutionary “Hello Lloyd” Direct Voice Command takes convenience to the next level, enabling hands-free operation using simple voice instructions. Smart Home Integration: These features offer unparalleled ease of use and integrate the AC effortlessly into your smart home ecosystem.
Mood On (Mood-Lighting): Personalized Ambiance
A unique aesthetic feature, Mood On (Mood-Lighting) offers ambient lighting options. This allows you to set the perfect atmosphere in your room, adapting to various moods, events, or seasons, enhancing the overall living experience.
Superior Air Delivery & Robust Durability: Widespread Comfort and Lasting Performance
The Stellar Duo ensures conditioned air reaches every corner while being built for lasting operation.
Impressive 18m Long Air Throw & Precision Control Smart 4-Way Swing
An 18m Long Air Throw ensures that conditioned air (whether cool or warm) effectively reaches every corner of the room, even in larger spaces, providing consistent climate control. The Precision Control Smart 4-Way Swing further enhances this by oscillating air horizontally and vertically, ensuring uniform and precise airflow distribution throughout the entire room, eliminating hot/cold spots.
Ultra-Wide Operating Voltage Range (100V – 300V): Unmatched Electrical Protection
Designed to operate effectively within a very wide voltage range, this feature offers superior protection to the AC from severe voltage fluctuations common in India. It ensures stable and reliable performance, minimizing the need for an external voltage stabilizer and safeguarding your investment.
Robust Warranty
Lloyd offers a comprehensive warranty package, including a 1-year warranty on the product, 5 years on functional parts (including PCB), and a substantial 10 years on the compressor.
