The air conditioning system in a floor-standing unit is unmounted but works just like a wall-mounted system. However, floor-standing ACs have the advantage of being portable, as you can move them to any part of the room. Additionally, they don’t take up wall space and are easier to access. Floor standing air conditioners are a preferred and convenient option for air conditioning of commercial facilities, gyms, restaurants and offices. Such a system is recommended for home air conditioning only in large rooms.
