What size unit? Happy so far?

They really have these systems figured out.

Helped a friend set 2 for his smallish 2 story home.
The biggest pain is attaching linesets behind the cassette, they give you a 3×5 hole to make the connections.
Fat fingers not apply lol.

Unfortunately my friend's cheaper off-brand's units insulation wrap, is not uv stable in the deep south…it falls apart after about a year.
Am sure Mitsubishi uses better materials.

Open end torque wrench, and and the spin flare is not something a diy'er will have.
We used 3 clicks of the elbow for torque specs ,or common sense.
After working behind other people's shoddy work in remodals,it's always a pleasure to open up your own walls …and see that craftsmanship is still rewarded years later!

I give it two AA's !
