I did a quick search on here, but didn't see anything, so if this has already been discussed, please forgive me. If not... I just heard there is a federal requirement to change all refrigerants to A2L by 2025. A2L is flammable, which means there are detection requirements, venting requirements, lineset requirements, etc.
The 2024 ICC mechanical code includes numerous A2L refrigerant specific changes. The changes are outlined here: https://www.iccsafe.org/wp-content/..._Related_Changes_Redline_08.23.2022_FINAL.pdf
My questions are;
1. Has anyone here worked on a project that had to comply with these new A2L requirements?
1.a. If so, how did it go?
2. What happens in locations that don't adopt the latest mechanical code before the federal requirement kicks in?
2.a. FL, for instance, runs a few years behind the model codes. Does that mean there could be a period in the near future where buildings are being permitted & built with flammable A2L refrigerants without the detection and venting requirements outlined in the 2024 ICC code?
