This HISENSE 1.0 horsepower (HP) air conditioner is available in both inverter (AI09CBGS) and non-inverter (AN09CBG) models. It uses R32 refrigerant, known for its environmentally friendly properties and energy efficiency. The 1.0HP capacity makes it suitable for cooling smaller rooms. The inverter model (AI09CBGS) offers variable speed cooling for more consistent temperatures and potentially lower energy consumption compared to the non-inverter model (AN09CBG), which operates at a fixed speed. Customers can choose between the two models based on their budget and desired energy efficiency.
