I'm building a 1700 square foot single level home on an ICF crawl space. Definitely want heat pumps. Ductless. Thinking 1 12000 in each bedroom (2 bedrooms) and 1 18000 in the living area. These should heat the entire home with the HVAC yes? We have electric heat (rarely be used hopefully) and a wood stove insert as well. I can't make my mind up to go high mount. Floor mount. Or. Ceiling? Are they all basically the same to install? Is one more efficient than the other? They cost around the same give or take a few hundred bucks. I'm in a colder climate as well. Any input would be appreciated.
