Chillwell is a terrible product. It does not and will not work properly. The ChillWell portable ac unit is another scam. The only cold air this ac unit will blow is the air your home air conditioning is blowing at the time. If you were to turn off your home AC unit and use the Chillwell, it will blow hot air.
Customer service is not available. Trying to return is nearly impossible. Instead, we called our Credit card company to report it and fight it. So far so good.
DO NOT BUY CHILL WELL PORTABLE AC
