Installing the EG4 12000 BTU Mini Split – Full Setup + 1 Month Review!

Tired of a room you can’t enjoy? In this video, I’m installing the EG4 12000 BTU mini split to finally make my family room usable again! I’ll take you step-by-step through the entire installation process — from mounting, line set connections, wiring, and startup.

But I won’t stop there — after living with it for a month, I’ll share my real-world experience, power usage, comfort level, and whether it’s worth it for your home or off-grid setup.

If you’ve been thinking about installing your own mini split or want to see how the EG4 system performs, this video will bring you along for the ride!
