Very efficient and quiet, for mild winters: it stops heating below 5 °F, so a cold climate needs Fujitsu’s Orion XLTH instead.
No store we check sells it online; the maker lists where to buy or who installs it.

The best value for heating through a cold winter, if you can pull a vacuum yourself or pay someone to. It holds its full rated heat at 5 °F for far less than a quick-connect unit that does the same.
Amazon $1,049.96 Della $1,049.96Full rated heat in deep cold at a fair price, for a self-installer comfortable with a vacuum pump. Della’s Optima Pro has near-identical certified ratings for a little less.
Amazon $1,311 Pioneer Mini Split store $1,318For mild to moderate winters: it heats only down to −4 °F and loses some of its heat in deep cold.
