That is about $1 a month more than the cheapest system its size, or roughly $90 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 2 of 22 — middle of the pack.
Looking at the RZF50DVMG 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
