Hey folks! I just installed a Mr. Cool DIY Mini-Split heat pump in my home, but I have some concerns. The linesets sat in my shed for about a year because of a job change and an injury, and I'm worried about them since they were exposed to high temps and humidity during that time. While I can't see any damage, I don't have a way to check if the vacuum in the linesets is still okay now that I've connected everything. I've contacted Mr. Cool for help but haven't heard back. Should I be worried about moisture in the system, and what should I do before turning it on?

You might need to hire someone to recover the refrigerant and check everything. Once moisture gets in, it can cause acid to form in the system, which is bad news. If it were me, I’d get a professional involved to ensure everything is safe and functional.
Without the right tools, it's tough to be sure. If you can get your hands on a vacuum pump and gauge set, do that before opening the refrigerant valves. It'll save you peace of mind and maybe some future headaches. If that's not an option, consider contacting an HVAC pro for a quick check—they can make sure everything’s good to go.
Honestly, it sounds like you've already done the hard part. If everything is connected and you're not seeing any leaks, just fire it up! There's no point in stressing over what you can't see. If the system works, great! If not, that's when you troubleshoot. Just monitor it closely after starting it up, and if something's off, you'll know and can address it then.
