Dual hose portable air conditioners are designed to take the hot air from the room and blow it outside while the other hose takes in air from the outside, letting the air conditioner cool it to release it into the room. Therefore one hose is called the exhaust hose and the other is called the intake hose. Dual hoses are usually placed on higher BTU portable air conditioners used for rooms of up to 500 sq ft. Before you go purchasing a dual hosed unit, you should be aware of the pros and cons.
Pros
