Mitsubishi R410A replacement heat pumps

| Posted in General Questions on
Have been hearing that R410A is being phased out in the US and Canada and that all of the major manufacturers will be introducing a new lineup of heat pumps using different refrigerants in 2025.
Does anyone have any updates on timelines on when these products will be announced and when they’ll be made available?
We’re in the middle of the build and being forced to decide now whether or not to order our heat pumps now or hold off a few more months in the hope that something new might be available (which may put our timelines at risk and end up costing a bunch extra in project management fees…)
Any insights appreciated!

The older 410A refrigerant isn't supposed to be used in any new heating/cooling equipment after January 1, 2025. That being said, there's a lot of existing equipment that uses that refrigerant and the product should be available for years into future. Personally, I wouldn't be worried about installing equipment (manufactured in 2024) with the older refrigerant.
I recently had a discussion with an HVAC contractor and he wasn't sure which of the new refrigerants to stock. He wasn't happy about the possibility of needing to carry three different products on his trucks.
I am just dealing with this now on (2) residential projects in NYC. We had R410A equipment from Mitsubishi (ASHP) and LG (split HWH) specified and our HVAC subs could find the Mitsubishi equipment for purchase in Jan/Feb but cannot find the LG equipment or Mitsubishi equipment for purchase as of March 2025.
We made the decision for one project (whose equipment will be ordered in about a year) to re-specify with the new refrigerants, which I think is R454B. THough we spoke with the MEP engineers and HVAC techs and they think R410A equipment will be serviceable for at least 10-15 years.
I think the decision is whether or not you want to take the risk of something in your system going catastrophically wrong in the next 10-15 years, because if you do, you will probably have to replace the whole thing (including lines, but MEP eng. was not 100%) or just respecify.
From my understanding the new residential equipment equivalents should be online now from Mitsubishi for specifiers and professionals, if not in the next two or three weeks.
Good luck
