Sizing drives the cost, not the brand
A heat pump has to be matched to the house through a load calculation, room by room, not picked by the size of the old furnace. Go too small and the compressor runs flat out and still can't keep up on the coldest days. Go too big and it short cycles, switching on and off fast enough that it never runs long enough to dehumidify the air right. Getting that number correct up front shapes which unit gets quoted and what the install involves.
