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.

100% of the time you are told something is or isn't available its because what ever they are putting in front of you is what they make the most money on.
We ordered the upgraded stainless steel appliances, but they installed the bottom-of-the-barrel Home Depot crap in the house. We were charged about three times what we could have paid had we sourced the appliances ourselves.
The AC unit they put in our 2,200 sqft home is an absolute joke. It's only a 3-ton unit that pretty much runs ALL DAY LONG. In Florida, the rule of thumb for AC is one ton per 500 sq ft. We expect that this undersized unit will destroy itself in a couple of years, and then we will be installing a correctly sized 5-ton unit.
For those of you building a new home, don't buy any of the upgrades. They use the cheapest materials and charge through the roof. Buy the basics that you want and can't add later - extensions for example - then go buy quality stuff once the home is built.
We were in the house less than a week before the "upgraded" stove and dishwasher were put to the curb, the fridge was placed in the garage, and new high-quality appliances were delivered.
