"DIY" vs Non-"DIY" Mini splits (lemmy.world)

Is there significant quality differences between DIY mini splits (Mr. Cool, Pioneer) and non-DIY mini splits (Mitsubishi, Daikin)?

I'm going to replace 4 window and portable AC units with something more permanent, because 2 are under-powered and only one provides heat. Thinking of installing 4 single-zone systems because only 1-2 would need to be on at the same time, and it would simplify installation a bit.

I will be diy-ing regardless, so I would prefer not needing to buy extra tools and refrigerant from shady suppliers. But, if non-DIY systems are significantly better, that's a trade-off I'm willing to make.

Agree a recovery pump was a big help. I already had a powerful vacuum pump, but I did buy a recovery pump, cylinder, gauges, and a scale.

You can still check for and find leaks with Better Bubble or similar leak detector.

These are also great to help prevent leaks if you don't have Nylog and a torque wrench/crowsfoots for the fittings. They're Teflon or similar. https://flareseal.com/
