True or False: Units using R-22 need to be replaced as of 2020?

Although R-22, also known as HCFC-22, has been phased out due to its ozone-depleting properties, the statement that units using R-22 need to be replaced as of 2020 is not entirely accurate. The production and import of R-22 were banned starting in 2020, which means that while new units cannot be manufactured using R-22, existing units that utilize this refrigerant can still operate as long as they are properly maintained and can obtain reclaimed R-22 for repairs.

Furthermore, many older systems still in operation can continue to use R-22 until they become inoperative, at which point replacements may be necessary. It's also important to note that in some areas or among certain users, there may be additional regulations or incentives that encourage replacement of R-22 systems with more environmentally-friendly alternatives. In summary, while there are restrictions on new production, existing units do not have to be replaced immediately, making the statement false.
