* R-22 Refrigerant: R-22 is a single component HCFC refrigerant with low ozone depletion potential. It has long been used in a variety of air-conditioning and refrigeration applications in a variety of markets. Production of R-22 will cease in 2015 per the Montreal Protocol. Also commonly known as Freon.

* R-410A is classified as an HFC refrigerant and has no undesirable ozone depleting properties because it does not contain any chlorine. The operating pressures of R-410A are approximately 50% to 70% higher than that of R-22. R-410A systems use synthetic polyol ester (POE) oil. Unfortunately, POE oils are hydroscopic, meaning they readily absorb water. This can degrade the oil, causing harm to the entire system. R-410A systems should not be left open to the atmosphere longer than absolutely necessary.
