We are sorry to hear this. Our portable evaporative air coolers work best in areas with a dry climate, with humidity levels below 50-60%. These also require ample cross ventilation along with dry heat for optimal cooling. You may need to check the environment conditions of the area you are operating the unit in, in order to ascertain why it did not cool the way it should have. Our customer support team will be able to look into all your concerns and troubleshoot for you. Please call us at
