A: Yes. Several manufactures have developed new systems that contain environmentally-friendly refrigerants such as R-410A (also known as Puron). Puron is a chlorine-free coolant that is safe for the Earth’s ozone-layer and delivers superior cooling than traditional refrigerants. In fact, by 2010, systems that use Freon and other refrigerants will be phased out and replaced with Puron-based systems. And by 2020, no more Freon can be manufactured.
