That is about $3 a month more than the cheapest system its size, or roughly $350 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 11 of 26 — middle of the pack.
