This Midea air conditioner utilizes R32 refrigerant and inverter technology for efficient and cost-effective cooling. It is available in three horsepower options (1.0HP, 1.5HP, and 2.0HP) to suit different room sizes. The inverter technology allows the compressor to adjust its speed, resulting in energy savings and more consistent temperature control compared to traditional air conditioners. R32 refrigerant is a more environmentally friendly option with a lower global warming potential than older refrigerants. Installation services are included.
