If I had to evacuate the system in the future it could be an issue but otherwise hoping for the best. The savings I had for a pretty simple instal would pay for two more new complete units.

What tools did you buy? Still have them? If I decide to DIY, do you want to sell them?

All yellow jacket made in USA tools. Flaring tool with brake, reamer, good gauges, US made vac pump. SK crows foot to torque properly. Plus nylog.

I still saved so much compared to the HVAC scam artists that way overcharge on these things around here.

The pump is great for auto work, gauges may need some day, ditto for flaring tool. Probably wouldn’t sell but I’d consider a loan if terms were favorable.

I think most line sets are not pre-charged except MrCool DIY kits that Vstech mentioned earlier.

I think most systems that have brazed connections have an inline filter/dryer.

Never looked into precharged, I used standard line sets on both of mine. Only difference being the type of insulation on them.
