Multiple Choice

There are no drop-in replacements for R-22 refrigerant.

Explanation:
Direct substitutions for R-22 without any changes do not exist. A true drop-in would have to match R-22’s operating pressures, temperature glide, and lubricant compatibility so the existing components (compressor, seals, oil, lubrication system) can run safely and efficiently as-is. In reality, refrigerants marketed as substitutes (like R-407C, R-410A, or others) require system modifications, such as oil changes, different pressures, or even hardware retrofits, because they don’t behave identically in an R-22 system. Because of these differences, you can’t simply swap in a replacement without adjustments, so the statement is true.
