I was able to buy some R-410a on eBay when I installed mine a couple years ago. Looking again, I don’t see any more listed.
The tools weren’t too expensive. I wasn’t able to buy lineset covers locally, and I’m sure I paid a little premium buying them online.
I wasn’t able to do a high pressure leak test because I was only able to get a low pressure nitrogen regulator. I ended up tearing my hair out for months because the system barely worked because there was a leak I didn’t find until I noticed oil on a fitting.
Having a recovery pump and cylinder would be invaluable for troubleshooting leaks. But they’re so expensive.
