Ductless minisplit Location
I am in the process of getting quotes for a new ductless mini-split heat pump for my house in Montreal area. The overall dimension of my home is about 30’x30′. The front of house is the wall where the stairs are.
I have quite a few quotes from different vendors (Carrier, Lennox, Directair, Daikin). I am still trying to compare them for their efficiency and reliability. Do you have any opinion on that? I would like the unit to be efficient to heat the house in winter, as winter are cold and long here in Montreal. The unit would cool the house about 20-30 days a year.
I am doubting the efficiency of the mini-split that would be located on the second floor. I have received 2 propositions for the location. The first one would be a air handler located where the red rectangle is. I am pretty sure that this would be useless to cool down the rooms and most of the air would be pushed down the staircase.
The second location (yellow square) would be a cassette. Do you have an opinion on the efficiency of this installation? Would this be enough to cool down the rooms? Would only the small hallway be cool and the unit be constantly cycling? Do you have an opinion about the reliability of such devices?
Thank you for your help.
