1987 The U.S. and 22 other countries sign the original Montreal protocol establishing timetables and phase out schedules for CFCs and HSFCs. In recent years the HVAC industry has supported global efforts to transition to safer non chlorine based refrigerants.
HFCs such as R410A, R407C and R134A are refrigerants of choice for this generation.
As we continue to transition to R410A, R407C and R134A, we could see technological changes and pressures that may bring newer refrigerants and more transition.
With increased attention to global warming and climate change we may see a new family of refrigerants and changes in refrigeration and air conditioning systems.
Energy shortages, along with higher utility bills may bring increased demand for maintenance and service procedures that guarantee HVAC systems operate at their peak performance.
