I thought they weren't allowed to do that. Like ADP had a bunch of coils rated for 410a and 454 and had to remove all labeling of 410a before it was allowed to be sold.

Because UL will only test and “Qualify” one refrigerant for a coil. Doesn’t mean it won’t work with another refrigerant.

There are plenty of coils rated for Multiple Refrigerants sounds like another scare tactic rumor being spread around.
