This product listing includes two Hisense 1.0HP air conditioner models: a non-inverter model (AN09CBG) and a 5-STAR inverter model (AI10TUGS). The non-inverter AC provides standard cooling, while the inverter model offers enhanced energy efficiency and potentially quieter operation due to its variable-speed compressor. The 5-STAR rating on the inverter model indicates a higher level of energy savings. Both models are suitable for cooling smaller rooms. Free shipping is included.
