IceCOLD® is a revolutionary breakthrough synthetic solution which is added to the cooling system's refrigerant. The system runs less because the vent air is colder. IceCOLD® improves coil heat transfer while delivering a substantial degree change in colder vent air. Some benefits of IceCOLD® are that it extends the compressor's life and reduces repair costs. It also reduces compressor noise while being the most cost effective way to enhance the system's performance.
