I'm in the process of getting bids to install a new HVAC system in my house. It is an old house with no ducting and only about 1200 square feet. I'm in Southern California and the house is west facing on top of a hill. I've gotten two very different opinions regarding placement of the supply registers.
One contractor said the supply's should be located closer to the perimeter walls and nearer to doors and windows. Another contractor was very sure that the best location is away from the perimeter and closer to the interior walls.

Logic tells me that the perimeter locations will be more efficient.

Please advise....thanks for your time.

Great site.
