What is the typical storage life of refrigerants used in residential and light commercial pumps?

The typical storage life of refrigerants used in residential and light commercial heat pumps can be classified as having an indefinite length of time, provided they are stored correctly. Refrigerants are chemical substances that do not degrade or lose their effectiveness over time when contained within a sealed cylinder. As long as the cylinder remains intact and there are no leaks, the refrigerants can be safely stored for extended periods without significant changes to their properties.

Correct storage conditions include keeping the refrigerants in a cool, dry place and ensuring that they are not exposed to extreme temperatures or direct sunlight, which could potentially affect the integrity of the containers. The stability of the refrigerant in its sealed state allows for indefinite storage, thus making this option the most accurate representation of refrigerants' storage capabilities in heat pump applications.
