We are getting a wall mounted HVAC system for the great room

We have decided that we’re going to have to buy a wall mounted HVAC unit for the great room in our house. We have always had issues with supplying heating and cooling to this room. I guess it’s because it’s such a large open area and it’s also two and a half stories high. It’s really hard for the furnace or the air conditioning to keep up with the heating and cooling demand in that part of the house because the air just goes right out of that room into the rest of the house. But as a result, it’s never very comfortable in that room. It’s a beautiful room, with a giant wood burning fireplace and very comfortable furniture. However, we hardly ever go in there to hang out as a family because in the winter, it’s just too cold in there. And then in the summer, it’s even worse. The heat from the sun shines in through the floor to ceiling windows and it makes the air conditioning from our central A/C system completely useless in that part of the house. We have been trying to figure out what to do in that room, and we knew that we didn’t want to run any more ductwork in there because it would ruin the beautiful oak beamed ceilings. Our HVAC company told us that they would suggest installing something called a ductless mini split air conditioning unit in the great room. This is a wall mounted HVAC unit that doesn’t need air ducts to provide heating and cooling.
