Blue Star HPYFAN-series DC inverter wall splits adjust compressor speed to your room's actual need, so the temperature stays steady and the electricity bill stays lower than with stop-start fixed-speed machines. Add Breezesync Wi-Fi app control, Self Clean hygiene and super-quiet night operation, and you have the smartest way to cool and heat a Nepali home. Every model carries a 1-year warranty plus a 10-year compressor warranty, and all three sizes (1.0, 1.5 and 2.0 Ton).
