  • 100% Copper- Blue Star air conditioner's outdoor units are 100% copper, precisely designed to ensure maximum efficiency of the cooling system.
  • Anti-Freeze Thermostat- The anti-freeze thermostat on the indoor coil is a safety feature. It stops the compressor when the unit is set at a very low temperature and runs in cool mode. This prevents frost from forming on the heat exchanger thus, protecting the unit.
  • Comfort Sleep- Intelligently senses variation in indoor temperatures and adjusts the same automatically, to keep you comfortable through the night.
  • Dry Mode for Cooling during the Monsoons- When the Dry Mode is turned on, your Blue Star air conditioner ensures reduction of excessive humidity within the room, so you stay comfortable when cooling the environment.
  • Elegant cleanable Panel- The front panel of the indoor units can be easily detached for periodic cleaning. This helps in maintenance of the AC.
  • High Efficiency Rotary Compressor- Engineered with “High-Energy Efficiency Rotary Compressor”, with a built-in accumulator, the compressors in Blue Star Air Conditioners are designed to enhance cooling performance at low energy consumption levels, increasing efficiency and reducing costs.
