Mini-Split Installation
How a mini-split gets installed and what it costs — DIY pre-charged systems vs a licensed pro, the line set, the electrical, and how to line up local quotes.
btuwise’s installation pages cover the part a calculator can’t: getting the system mounted, connected and running safely. A pre-charged DIY mini-split (MrCool DIY and similar) with quick-connect line sets is genuinely homeowner-installable; anything that needs the refrigerant lines flared, vacuumed and charged is a job for a licensed HVAC pro with EPA-608 certification, and the dedicated circuit belongs to a licensed electrician. These guides explain the difference honestly, what installation costs and what drives it, and how to get matched with vetted local installers so you can compare quotes, timing and warranty before you commit.
