In 1925, Carrier found the problem and approach Paramount a solution to their problem. He persuaded Paramount Pictures Coporation to part with 65,000 dollars to install a climate control device. Paramount at that time is constructing the Rivoli Theatre, a flagship movie house in Times Square in New York City. He installed the machine in the movie theatre and there it is, on Memorial Day, the air-conditioning is a great hit to all movie goers and Paramount not only made huge profit all years round, Carrier also made his big step forwards as he is appointed to install the climate control technology in 300 movie theaters over the next 5 years.
