Minisplits install costs are the biggest scam in the US, in Japan installs regularly cost under $1000 (that includes the minisplit!).

They're literally designed to be easy to install, but in the US licensing requirements tend to be insane (in my state it's 2 years apprenticeship experience for their 'easier to get' mini-split license) and HVAC companies make more off whole home systems.

These things are regularly installed DIY by homeowners (illegally most of the time but you know), it doesn't take two years of experience to be able to install these without issue. 2 weeks, or half a dozen installs surely would be more than enough.
