In a cold winter climate (Traverse City, MI) does a mini-split ducted heat pump system make sense over a GSHP?
We are starting to design a new build near Traverse City MI where average temperature for three months of the year do not exceed 32F. Does an air source heat pump still make sense as I’ve read at temperatures below 37F it needs to run continuously. We are designing the house to have a very tight envelope with heat recovery and high R value insulation.

Mike,
In my opinion, an air-source minisplit system will probably make more sense than a GSHP -- as long as you have designed a very tight, well insulated house with excellent windows.
