Early mechanical refrigeration systems employed sulfur dioxide gas or anhydrous ammonia, with small home refrigerators primarily using the former. Being toxic, sulfur dioxide rapidly disappeared from the market with the introduction of Freon. Ammonia is still used in some large commercial plants.

Use of highly purified liquefied propane gas as a refrigerant is gaining favor, especially in systems designed for R-12, R-22 or R-134a. Moreover, propane is nontoxic. An odorant, such as ethyl mercaptan, can be added in trace amounts to alert persons of system leaks
