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.
I had to make this choice recently and went just with a regular split VS diy.
There isn’t that much difference, but you have much more choice in the non diy.
The only specialized tools I had to buy was vacuum pump and flare tool, for cutting copper lines.
If you take your time and are good diyer it’s really not that hard.
