This is a used R410A refrigerant cassette type air conditioning unit, likely either a Daikin or Acson brand. It falls within the 2.5 to 3.0 horsepower range. The unit is an expose type, meaning it's designed to be mounted visibly on the ceiling. It is a non-inverter type, so it operates at a fixed speed and may be less energy-efficient than inverter models. The listed price does NOT include installation services.
