Cost for mini split AC units in Boston, MA

[Haley M.]

Hi everyone, we're considering putting mini splits in our Boston unit for AC only (heat is natural gas). The unit is 600 sq. feet and I know we need an exterior unit of 20,000 BTUs and two indoor units. We're on the top floor with direct roof access. I've gotten a few quotes and I'm in sticker shock for how much it will cost to get these installed. Everyone has been over $10,000. Does this sound reasonable? Does anyone have any other recommendations or resources for mini splits, or is this what I should expect? Thanks in advance!
