A Delhi cooling season runs eight months, not three. The unit switches on in late March and is still working in October, which means efficiency is not a line on a sticker — it is the difference across a whole year's bills. At 5 Star and an ISEER of 3.68, this is the top of the BEE ladder in window format, rated at 1070.79 kWh a year. The DUAL Inverter compressor is what earns it: instead of slamming on and off like a fixed-speed unit, it modulates its speed to hold the room where you set it, drawing only the power the weather actually demands. Add Convertible 4-in-1 to dial capacity down for one person on a mild evening, and the meter reflects how you live rather than the hottest day of June.
DUAL Inverter Compressor + Convertible 4-in-1 — capacity that follows the room
A fixed-capacity AC is either too much or too little for most of the day. LG's DUAL Rotary Inverter compressor varies its speed continuously — a hard, fast pull-down when you walk in at 3 PM, then a low, steady hum through the night. That is where the 44 dB comes from: at steady state the compressor is barely working, and a window AC that runs at 44 dB is a window AC you can sleep beside. Convertible 4-in-1 lets you set the effective cooling capacity to the moment — full power for a packed drawing room in peak May, a fraction of it for one person and a book on a mild April evening. Because the inverter modulates at every setting, the lower steps stay efficient instead of paying a fixed-speed penalty.
100% copper tubes with Ocean Black Protection — built for the weather it sits in
A window AC's condenser section hangs outside, taking the monsoon rain, the summer dust and Delhi NCR's winter pollution head-on all year. The tubes here are 100% copper — faster heat transfer, better efficiency, and far easier to service than aluminium — and they carry Ocean Black Protection, LG's anti-corrosion coating originally engineered for salt-laden coastal air. On a Delhi balcony or a Ghaziabad window ledge, that coating is what keeps the coil clean-surfaced and exchanging heat properly into its eighth and ninth summer. Stabilizer-free operation takes care of the other local reality: the voltage swings that come with a loaded grid in June, handled without an extra box on the wall.

🛠️ The spec sheet at a glance
A window unit is a single self-contained box that seats into an existing opening — no outdoor unit to hang, no long copper run through the wall. In older Delhi colonies and rented flats, that is often what makes air conditioning possible at all.
The top BEE band in window format, rated at 1070.79 kWh a year. Over a Delhi cooling season that runs March to October, the efficiency band is what shows up on the bill month after month.
A high-density filter traps dust, allergens and airborne particles — worth having in a city where the AC runs long hours and the winter AQI puts everything indoors.
Independent horizontal and vertical louvre control spreads cool air evenly across a 111–150 sq ft room, instead of a cold draught over one chair and a warm far corner.
1 year comprehensive on the whole product, 5 years on PCB and motor — the electronics that matter — and 10 years on the DUAL Inverter compressor. Coverage that matches how long this unit is meant to run.
