Hi. I'm in the process of building a new third floor on top of my two storey semi-detached downtown toronto home. It will contain a master bedroom, ensuire bathroom, reading area and small deck. Total floorspace of just under 500 sqft. The plans call for a supplemental HVAC system for this floor. I had originally figured a split system ductless would be the right choice. I've attached the floorplan below.
I had a discussion with my contractor yesterday. The HVAC guy that he is dealing with has suggested that I don't need a split system, just a single outlet that will supply the heat and cooling to the entire floor. The contractor is saying that if the outlet is located over the sliding doors to the deck it will sufficient to get heat and cooling to all rooms, with a supplemental electric register for when it gets really cold occasionally. I'm concerned however that the bedroom would not get sufficient heat/cool, especially when we have the door to the hallway closed (we would typically leave it open during the day, but close it at night). Note that the floor in the ensuite bathroom will have radiant heat, so it would probably be ok heatwise in any case.
My thought was that it would be a split system with one outlet over the sliding door, and one outlet in our bedroom. Still with an electric register in both rooms for when it gets really cold.
Any professional advice out there?
