The summer heat can be unpredictable, which is why you need a portable ac to match. Bring in this HOMCOM air con unit which does four jobs in one. It cools, ventilates, dehumidifies and also has a sleep mode. 'Cool' keeps the area at a constant temperature, 'ventilate' controls the speed of the fan, 'dehumidify' dries out the moisture in the air and 'sleep' gradually increases the temperature by every hour. Please note: included exhaust hose must be connected for this air con to work.
