Enhancing Performance of Residential and Commercial AC Systems with an R-22 Replacement Refrigerant

Among the options offered in the Freon™ refrigerant portfolio, Freon™ 407C (R-407C) is a high-performance blend. This alternative to R-22 in positive displacement air conditioning (AC) equipment can also:

• Replace R-502 in new and retrofitted medium-temperature applications with evaporator temperatures above -6.7 °CC (20 °F)
• Work in existing medium-temperature applications
• Work in new or existing residential and commercial AC and heat pumps

Replacing R-22 with Freon™ 407C in these systems requires switching to polyolester (POE) oil. 

Features and Benefits

Freon™ 407C has been a popular R-22 replacement because of its properties, which include:

• Similar cooling capacity, energy efficiency, and pressures as R-22 in systems
• An ability to be topped off after a leak, multiple times, with minimal impact on system performance
• Safety; Freon™ 407C has an ASHRAE A1 safety classification
