That is about $8 a month more than the cheapest system its size, or roughly $930 over ten years — before you weigh purchase price, which often runs the other way.
It is not an inefficient unit, though. It sits at the larger end of its size group, so it works harder for the same rating. On efficiency alone it ranks 10 of 21 — middle of the pack.
Cheaper systems the same size
Systems around the same size that cost less to run, closest in size first. Cheaper to run is not the same as the better buy — purchase price, indoor units, and how well it is installed all sit outside these figures.

Looking at the RAV-GE1801AP-SG for your home?
This is the outdoor half of a pair. The indoor unit is the half you live with, and it should be named before anything is agreed.
What to pin down before you commit
- The paired indoor model number — the unit that mounts in the room
- Whether the capacity suits that room, and how that was decided
- What happens to the existing piping, drainage and bracket
- Whether the old unit is being removed and disposed of
