New construction - only single stage HVAC systems are available
There's been lots of discussions on some other threads about the benefits of dual stage or variable speed HVAC systems and I was pretty sold on this idea. I did just learn that as of Jan 2025, the only option is the Carrier Performance 15 Single Stage system.
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. |

Personally, I would want the latest refrigerant regardless of what type of system I purchased. |

For R-410A Systems (like split systems): December 31, 2025. However, the EPA issued an Interim Final Rule allowing installation of these systems until January 1, 2026, if they were manufactured before January 1, 2025. For R-410A Products (like self-contained units): December 31, 2027. |

"It's not that we don't want to offer them, because we did when they were available. The HVAC companies are not manufacturing them right now, due to government changes on 1/1/25 to change refrigerants" Now clearly that above statement isn't correct - there is some miscommunication or misunderstanding there as these thing are clearly available. They must have anticipated some supply hiccups with this new rule regarding refrigerant change and tried to simplify things by only making one type of unit available. I am hoping to have them reconsider this policy ASAP as I need to finalize everythign on the week of July 28. |
Sunshine can install anything they want as replacement equipment. But, if I am buying a new house, I want the latest equipment with the latest refrigerant, not something that is grandfathered in.

And thinking about what you were telling us further it’s possible that The Villages doesn’t want to change the design paperwork on your new house to accommodate this change. Similar to when people try to add a room or stretch a garage., etc,, The Villages isn’t doing this anymore for new builds like they used to. Maybe that’s the problem and if so, I’d fight that like crazy. |
I’d be happy with the latest. You’ll have less issues to worry about down the road.

Variable speed more efficient.
The variable speed units will have a lower operating cost. Cycle on and off less resulting in more consistent temperature. Dislike getting a discontinued refrigerant, but expect it to continue to be available for reasonable life of units, or a substitute will be made.
Are the variable speed units not available with the new refrigerant or is it that the "contractor grade" units are not yet available? Contractor grade units are sold to developers at a lower cost than the retail product but generally have inferior construction. Since most developers put in the cheapest stuff regardless of efficiency, producing contractor grade equivalents of more expensive units may not be a priority for Carrier. |
The Villages action to stop offering variable speed systems is likely a risk mitigation decision. That is, the supply chain for the new refrigerant systems may not be able to do timely deliveries at the moment due to this new regulation. TV is all about building to a strict schedule.

They are buying builder grade HVAC systems and get Hugh discounts due to the bulk quantity. If they were to buy one at a time, special order units their discounts would be severely reduced. Their installers are trained for garden variety installs not the suffisticated units you are after. Their argument about the refrigerants makes no sense. How come the private installers can get whatever you want with whatever refrigerant that is mandated by law. This issue is purely a I don’t want to vs a can’t do. JUST MY OPINION!
