As a PSA, mini splits are pretty easy to self-install, and it can save you a bundle, even when buying all the equipment new. Lots of youtube videos on how to do it, though I'd add that most of them show using a manifold with analog gauges to do a vacuum test. You should really get a digital micron gauge and pull a deep vacuum.

- bombcar 5mo agoEven where it's not legal you can often do much of the work and hire a licensed contractor for the "final step". It can be worth asking around.
- ericd 5mo agoGood point, though you generally don’t really have to handle coolant for mini splits, they come precharged. You mainly have to add more if you have a longer lineset. I’ve heard the online EPA course/test for coolant cert is pretty easy, though. The main thing is just making sure you test the lineset well, including deep vacuum decay, and ideally a nitrogen high pressure test.
