A refrigerant recovery machine became necessary when it was discovered that chlorofluorcarbons (CFCs) were depleting the ozone layer. Once this was discovered, Freon was taken off of the market and maintenance facilities were advised that they needed to have a way of capturing the Freon when extracted. It became illegal to release it into the atmosphere. The recovery machine was quickly developed and certification course was necessary to own and operate one at a shop.

Selection Considerations
To avoid fines for the improper removal of refrigerants, buyers in the United States should select refrigerant recovery machines that comply with standards from the Environmental Protection Agency (EPA).
Some refrigerant recovery machines recover refrigerants as liquids while others recover vapor. For example, propane can be recovered either as a gas or as liquid propane (LP). Because it does not require pressurization, liquid recovery is faster than vapor recovery. A refrigerant recovery machine pump can either use oil or be oil-less, which is a key maintenance consideration. Generally, higher end systems recover liquids and feature oil-less pumps.
The type of refrigerants that a system can recover is also an important consideration. Although some units can remove both high-pressure and medium-pressure refrigerants, others cannot. For example, some refrigerant recovery machines may not be designed to remove R410A, a higher-pressure refrigerant.
