This decision appears to be driven by EPA mandate which requires a phase-out of HFC refrigerants (like R-410A) in favor of newer, lower-global-warming-potential (GWP) refrigerants—beginning in 2025.
As of January 1, 2025, manufacturers will no longer be able to produce new HVAC systems that use R-410A. The two most common replacements are expected to be:
* R-32 and
* R-454B
So in anticipation of the potential for supply issues during this transition period, it seems that TV just simply decreed that these variable speed units are just not going to be offered.
However - when Iook at the website for Sunshine AC, these units are absolutely available. It's my understanding that systems with the old R-401A refrigerant can still be installed in 2025 as long as the system was manufactured prior to 2025.
Hopefully the powers that be will soon again allow for more upgraded systems to be become available.

Question - Is Sunshine installing the old R-410A refrigerant in their variable speed systems, or the newer refrigerants? If they are installing systems that were manufactured last year or even before that, I don't blame The Villages for not offering systems that were manufactured more than a year ago. They are selling new houses.
Personally, I would want the latest refrigerant regardless of what type of system I purchased.
