What is the most common HCFC today?

Explanation:
R-22 has been the standard refrigerant for many air conditioning and small refrigeration systems, which is why it’s the most commonly encountered HCFC. Its widespread adoption in residential and light commercial equipment gave it a dominant presence in service inventories and repair work. The other HCFCs are more specialized or less widely used across the industry, and R-32 is actually an HFC, not an HCFC. So the best answer reflects the historical and practical prevalence of R-22 in typical HVAC setups.
