Which refrigerant is HCFC and commonly used in older residential HVAC systems?

Explanation:
R-22 is an HCFC, and it was the standard refrigerant used in many older residential air-conditioning systems. HCFCs contain chlorine, which is why they contribute to ozone depletion, though they’re less damaging than the earlier CFCs. Because of environmental regulations, production and import of R-22 have been phased down, so newer systems switched to R-410A, which has no chlorine. The other refrigerants mentioned serve different purposes: R-134a is an HFC used in some newer applications (like automotive AC), and R-404A is used mainly in commercial refrigeration. So, the one that fits being HCFC and common in older home systems is R-22.
