We used Harp two summers ago, cost us $12,000 for three wall units with the option of adding a fourth. Our place is only 1500 sqft though. And as mentioned, we had to upgrade our panel first, that was another $1000 or so.

We had HARP install 5 heads in a 3,000 square foot house with a third floor) the kitchen already had one) and it was about $25,000. We financed through the state’s Green Bank. Eversource now has really large heat pump discounts that are worth looking into. Geothermal might be your best bet if you’re willing to invest more up front.
