October 15, 20205 yr Thinking about replacing a couple of old AC units and need to decide which refrigerant to go with. Have read a bit on it and I am undecided. Apparently R-32 is supposed to be the new standard, but I am not sure if it is really better and no idea how common it is in Thailand. Thoughts?
October 15, 20205 yr My thoughts would be you think too much go with whatever refrigerant comes with the AC unit you buy.

R-410A has a GWP (Global Warming Potential) of 2,090 R-32 has a GWP of 675. So 1 kg of R-410A is equal to 2,090 kg of carbon. You should be careful not to release either but R-32 is less bad. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate Easier to recycle than R410A, as R32 is a single component refrigerant

Do you have any experience with either?
October 16, 20205 yr To think long term, go for R32 in case of R410A phases out. I doubt you can feel the difference. Phasing out part is inevitable in my opinion.

I do not need to be to know that R32 is better, or at least less bad, than R410A. You have to judge if the savings on running costs will be more than the extra cost of the unit.
