The summer heat can be unpredictable, which is why you need a multi-functional cooling unit to match. Bring in this HOMCOM air conditioning unit for home which does four jobs in one. Our air conditioners cool, ventilate, dehumidify and also have 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 1 °C every hour.
