What are the disadvantages of R-410A?
Systems that use R-410A will run at a higher pressure than systems using R-22 (approximately 60% higher). The number of service technicians currently trained and equipped to service these units are, at this time, very limited. The standard gauges, tools, and recovery equipment are not compatible for use on R-410A systems. This limits the number of service personnel qualified to service R-410A systems.
