Guys, I've read many of the Mr. Cool posts and it seems the general concensus is very positive. I really want to go that way as I am a pretty serious DIYer. I'm thinking of putting one in my wife's greenhouse on the recomendation of my electrician who has seen several perform well in other greenhouses. My concern is how much of a DIY project I'm getting into. I was an early adopted of Split Ductless in my old house. The old one was a Mitsubishi Circa 2013 it was professionally installed and seemed to **** out every 1.5-2 years. I would call the man and he'd do something with the lines and it would be working again. I feel like that experience was more of a problem of being and early adopter (at least where I lived) and possibly poor installation. I'm not sure I want to invest in all of the things I'm reading about on this forum (Vacuum pump, Micron Meter, Argon...). If I get a Mr Cool, how likely is it to become yet another hobby for me?

I just finished putting in a 9k Pioneer system yesterday. the price difference between the Pioneer + micron gauge, vac pump and adapters is the price of the Mr Cool system and you'll have all the tools and probably do a better job because those push connectors are guaranteed to lose some level of vacuum as you plug them in. I'm seeing a $850 difference in price. I got a CPS micron guage, harbor freight 2-stage pump, flaring kit and adapters ~$550. I spent another $400 on nitrogen tank, but in reality I was comfortable after seeing an overnight vacuum hold that barely moved. Just more peace of mind than anything.

Most mini-split issues are due to poor install. Ductless splits have existed for probably close to 40 years now. The biggest issue are the flare connections. They need a bit of prep and care to ensure they're correct. They have to be torqued to a specific value, flared correctly, and special assembly lube helps as well. Almost all (name brand) minisplits specify a minimum of a 24 hour leak test at very high pressure (400+ PSI). Almost no installers do any of that, so a lot of them end up with very small leaks.
If you take your time, do the flares properly, it should provide years of service.

If you havent already purchased the unit, Ingrams has great support if you buy through them. Many people here that have had issues had Ingrams send out replacement parts with very little hassle.
