Interesting.
The eco friendly refrigerant is essentially PROPANE or close to it as I understand it. Cheaper than the ozone saving alternatives. A friend tried to convince me this was a good thing to do instead of spending nearly $600 for a 20 lb canister of the “old” refrigerant to top up my HVAC unit last year. I demurred and sprang for the $600 even though I was selling the house.
PROPANE ??

Wow! I don’t know how anyone could have thought this a good idea. The green idiots think they know it all.
