Manual J help for upstairs only
Hey Everyone again.
I was fortunate enough to get some good guidance on preparing my second floor (hats off to Dana and Martin). Now that all the insulation is in, need your help calculating Manual J loads specifically for cooling since we already have hot water heat upstairs. Looking into getting a ductless mini split unit to cool.
I have drawn out to my best ability and marked everything that I thought needed. Based on my guestimates, I’m zeroing in on 6k BTU or half a ton unit to be able to cool both the bedroom and the bathroom (when door is open to the bathroom).
Dana earlier advised on using a single head unit for better efficiency, so I’m thinking of the Mitsubishi 6k BTU 33.1 Seer Ductless H2i Hyper heat pump system. There is one with pan and without, not really sure what the pan is for. Unit would be placed to blow away from the bathroom door, and more towards the stairs. Will 6k be enough to cool inside bathroom with door open or should I go slightly higher?
