Our place was quoted at $28-30K. We would qualify for the full rebate, so we would have had to pay about half of that. Mind you we would have also had to install some sort of electric system for domestic hot water, so that would add even more. Im not sure how the numbers work with this. I never got an official paper quote, so I have no idea what was labor, and what was materials. We decided against it as there were way too many cons, and not enough pros to go with the heat pump.
